Highly Pathogenic Avian Influenza (HPAI) H5N1 is a major problem in poultry industry in many countries. It became endemic disease in Indonesia since 2003. Recently, research revealed that current circulate HPAI in Indonesia has switched from clades 2.1 to 2.3.2.1. To eradicate this disease, methods such as stamping out and quarantine seem not suitable applied since poultry industry is one of main sector in agricultural commodity in some areas such as Central Java, Yogyakarta, and East Java. It provides large of job opportunity for native people from rural to city areas. To prevent the morbidity of this disease, vaccination use local seed is primarily needed. This research was conducted to explore local isolate of HPAI clade 2.3.2.1 as vaccine candidate. Samples were obtained from some areas in East Java where outbreak occurred. Molecular characteristic according to Neuraminidase (N) gene was conducted. Samples has close relativity to circulating virus was used as seed vaccine then processed into killed vaccine production. It was challenged to observe the protectivity on poultry. The effectivity of the vaccine was measured through Haemagglutination Inhibition (HI) assay. The result of study showed that isolate DOD_3_2013 has close relativity to circulating virus thus it used as vaccine candidate. Challenged test showed that this vaccine candidate induced higher antibody titer compared to control. The average of antibody titer was 8.2 (log2) with the protection level 100%. It is concluded that this isolate could be used as vaccine candidate to eradicate HPAI clade 2.3.2.1 around East Java.

Mycoplasma gallisepticum causes major health hazards in poultry birds in Bangladesh which results in huge economic losses every year. This study was carried out to estimate and analyze the prevalence of Mycoplasma gallisepticum (MG) infection in commercial layer chickens at Kishoreganj district of Bangladesh during the period from November 2018 to October 2019. A total of 505 serum samples from 94 commercial layer farms of Kishoreganj Sadar Upazila and Pakundia Upazila of Kishoreganj district were collected. Serum plate agglutination (SPA) was performed to detect the antibody against MG. Prevalence was found 73% in the Kishoreganj district by SPA test. MG was significantly (P<0.01) more prevalent in Pakundia Upazila 82% than Kishoreganj Sadar Upazila 61.11%. In case of season, winter season had significantly higher (X^2=30.94, p=0.000) prevalence of MG infection. In relation to age, seroprevalence of MG infection was highest 78% in birds of 65 weeks’ age and lowest 71% in 6-25 weeks’ age birds. Any significant (P>0.05) association was not found between flock size and seroprevalence of MG. Seroprevalence was highest in flock containing above 2600 birds. MG infection is prevalent in the chicken population of Kishoreganj district, Bangladesh. Measures should be taken for successful prevention and control of this disease in Bangladesh.

Anaplasma spp. are significant arthropod-borne bacteria globally, but documented information about anaplasmosis in small ruminants in the north of Iraq is insufficient. Hence, this study was conducted to determine the prevalence of Anaplasma spp. and identify sheep and goat tick vector populations in Sulaymaniyah Governorate, north Iraq. The study population consisted of 470 sheep and 145 goats from 45 livestock farms in 10 geographical locations of Sulaymaniyah Governorate. The study was accomplished from April to December 2017. Blood samples were taken from the jugular vein and used for DNA extraction. Polymerase chain reaction (PCR) was conducted using primers based on the 16S rRNA of Anaplasma spp. Fragments of PCR products were sequenced for phylogenetic analysis. The prevalence of Anaplasma spp. was 58.9% based on the PCR results. Furthermore, 58.9% of sheep and 57.9% of goats were positive for anaplasmosis. The sequences represented 100% identity with previously documented GenBank isolates of A. ovis from Iran, the Netherlands, China, and Mongolia. Altogether, 150 Ixodid ticks were picked from small ruminants within the same flocks and were identified based on morphological features. Various infestation rates were observed; about 40% of the Ixodid ticks belonged to Rhipicephalus sanguineus, 34% belonged to Rhipicephalus turanicus, 18% were Hyalomma anatolicum, and 8% were Boophilus microplus (Rhipicephalus microplus). The present report is the first molecular study of Anaplasma species in small ruminants from Sulaymaniyah Governorate in northern Iraq to the best of our knowledge. The study concluded that anaplasmosis was endemic in small ruminants from the investigated areas.

The aim of our study is to evaluate the effect of Apsa-mos® as immunostimulant on the level of antibodies in broiler chickens vaccinated with Newcastle disease live attenuated vaccine (β1 and lasota strain) at 10, 24-day old respectively. Forty, one-day-old chicks were reared in this experiment. They were divide into four groups and treated as follows: Chicks in the 1st group were treated as control one (G1); Chicks in the group 2 (G2), were vaccinated with live attenuated β1 NDV vaccine at 10 days followed by attenuated lasota NDV strain vaccine at 24 days of age, chicks in the group three (G3) were vaccinated as in group 2 but amended with Apsa-mos® at a rate of 1 mg / kg of feed; Chicks in the 4th treatment was given Apsa-mos® only at a rate of 1 mg / kg of feed. Antibody titers after administration of NDV vaccines were estimated using ELISA technique. The results showed a significant difference in the titers between the vaccinated and non-vaccinated birds with higher values when Apsa- mose® was added, in comparison with groups 1 and 4. No significant changes were noticed between granulocytes differential counts and in the values of stress factor of heterophiles/lymphocytes (H/L ratio) in all treated groups. Amending Apsa-mos® to the feeds of the treated birds G3 and G4 has no negative effect on the treated and play a positive role by restoring the normal architecture of lymphoid tissues of bursa of Fabrecious and caecal tonsils. we concluded that the giving of Apsa-mos improve the immune state of the chicks in both types humeral and cellular immunity especially in G3 and decreased the influence of the vaccine in this group and increase the immunity in G4 also Apsa-mos decrease the effect of the vaccine in G3 seen in histological changes in bursa of fabricious and cecal tonsils.

This is a primary study in detecting a specific antibody of the Maedi-visna virus (MVV) in blood samples and viral antigen in nasal swabs from sheep. Two hundred and forty nasal swabs and blood samples were collected from sheep of different ages and health statuses in Nineveh province, Iraq. Enzyme-linked immune sorbent assay was used to detect specific antibodies against MVV specific proteins gp135 and p25, Whereas Agar gel immune diffusion (AGID) was used to detect antigens from nasal swabs using specific antibodies against gp135 proteins of MVV. Serological results using ELISA showed the total prevalence of MMV 22.9% and the highest prevalence of infection in sheep less than one-year-old 36.5% when compared with older animals 8.4%. Animals that suffering from respiratory problems had a higher prevalence of infection 25.7% compared with healthy animals 6.9%. AGID showed an identical reaction between Maedi-visna viruses and specific rabbit antisera with a total infection rate of 12.9%. The highest prevalence of infection was 22.4% recorded in animals less than one-year-old, the lowest percentage of infection in animals more than two years of age was 1.4%. Animals suffering from respiratory signs also showed high prevalence of infection 13.8%, while the lowest percentage of infection were recorded in healthy animals 4.6%. It has been concluded that the high prevalence of infection rate in sheep less than one-year-old and the animals which suffered from respiratory problems had higher prevalence according to ELISA and AGID testes.

Histopathological alterations in the liver of intermediated hosts infected with Echinococcus granulosus parasite can be occurred by necrotic expansion as a result of an increase in growth of the parasite larva stage (metacestode), which may cause perturbation in production of liver function markers. Thus, this study aims to determinate the liver biochemical profile and some serum electrolytes of E. granulosus-infected sheep at different hydatid cyst infection ratios (IRs). fifty livers from naturally E. granulosus-infected sheep with five livers from uninfected-sheep as a control group were enrolled in this study. Cardiac blood samples under sterilized conditions were gently collected and isolated sera were biochemically assayed for determination of liver function markers including; Aspartate transaminase (AST), Alanine transaminase (ALT), alkaline phosphatase (ALP), Albumin (ALB) and total protein (TP), as well as the level of some serum electrolytes including Ca, K, Na and Cl using fully automatic biochemical analyzer, FUJI-Film. The current data indicated a progressive increase in the level of AST, ALT, ALP, Ca and K. The level of ALB and TP were gradually declined with a rise of liver infection ratio with hydatid cysts. In conclusion, the current findings indicated perturbation of liver function markers and the level of some serum electrolytes, mainly Ca and K in E. granulosus-infected sheep based on the infection ratio of liver. Additionally, acute and chronic infection of E. granulosus parasites in sheep can be determined based on the level of liver function markers in serum.

The study included 70 local buffalo animals (between six months and two years), 50 buffalo were confirmed to be infected with gastrointestinal worms and 20 were considering as a control group. The results of the feces tests showed that local buffalo was infected with different types of worms. It was observed that worm incidence was as follows: 85% Nematodes, 10% Cestode and 5% Trematode. The results of the study showed a significant decrease in the total number of red blood cells, hemoglobin concentration, packed cell volume, total number of platelets, and significant increase was observed in the total number of white blood cells and was most likely caused by a significant increase in the rates of eosinophil's. Also the results showed that the effect of worms on some biochemical parameters was significant decrease in total protein concentration, albumin, and globulin. So, it could be concluding that buffalo spread in the city of Samarra suffers from parasitic diseases that affect the health of animals, through change the study criteria, so a therapeutic program must be adopted by cattle breeders to control parasitic diseases and thus improve the health and production of animals.

The current study was contributed to the analysis of the nucleotide sequence pattern of the nucleotide sequence of the tissue DNA isolates based on the Internal Transcribed Spacer ribosomal DNA (ITS2rDNA) gene and Cytochrome c oxidase subunit 1 mitochondrial DNA (COX1 mtDNA) using the traditional polymerase chain reaction (150 samples of abomasum collected directly from camel carcasses after working in Al-Najaf slaughterhouse from 1/10/2019 to 1/2/2020). ITS2rDNA were well suited for the prepared primer with size783 bp and identical ratio ranged 81.17-99.73% of the same species, as indicated a high similarity of the isolates taken from two-humped camels in China or less related to Parabronema skrjabini in sheep and goat. In addition, the study identified the number of the mutations within the four COX1 gene and ITS-2 region, which were the most conservative region of the host's species, supporting the concept of host specificity with Parabronema skrjabini. The COX1 gene and ITS-2 region applied to confirm the diagnosis using a universal primer, as it included eight isolates with a size of 689 bp, identical values were ranged from 84.99-98.02% depending on the multiple sequence alignment and showed an increase in the substitution level among isolates at an upper taxonomic level. Studying of the COX1 gene and ITS-2 region in Parabronema skrjabini demonstrated a significant relation in the cluster and an early common ancestor with isolates of the two-humped camel (China). As for the COX1 gene and ITS-2 region, the phylogenetic relationship supported the ribosomal gene results, especially with Habronema muscae or related species such as Habronema majus, Dirofilaria repens, Dipetalonema evansi, Setaria tundra, Cercopithifilaria sp towards the root node. Therefore, considering COX1 gene and ITS-2 region as an ideal tool in determining the phylogenetic history of the sequence maps, but less conservative mode than the ITS2 ribosome gene based to a taxonomic species level.

Current work aims to investigate the brain blood supply of the local rabbit, where 14 rabbits of both sexes were used with weights ranging from 3-3.5 kg. This study revealed that the rabbit's brain is supplied by the vertebral and internal carotid artery (ICA). The union of the vertebral arteries creates the basilar artery that runs on the ventral surface of the pons and medulla oblongata, forming at its end the posterior communicating arteries (PCA), as well as at the path of the basilar artery from which the following arteries are formed, which are the anterior cerebellar arteries, pons arteries, 1st posterior cerebellar artery, 2nd posterior cerebellar artery, and the medullary arteries. The ICA enters the cranium through the foramen lacerum, forming the anterior carotid network, from which an artery exits anteriorly, called the intracranial part of the ICA, and caudally exits the (PCA). The following arteries are created from the intracranial part of the ICA, which is the accessory anterior communicating artery that connects with the posterior communicating artery and the posterior cerebral artery (PCEA) forming the closed circle of Willis, the middle cerebral artery is also created anteriorly and laterally to distributed on the two cerebral hemispheres of the brain, as well as the anterior cerebral artery which directed forward to gives the marginal artery which represents the first terminal branch of the anterior cerebral artery, and at the marginal artery going toward the olfactory tract and then to the olfactory bulb from which the internal ethmoidal artery is created. The anterior communicating artery originates from the anterior cerebral artery and it is a small artery communicating the left and right anterior cerebral arteries with each other, and the posterior cerebral artery originates from the PCA, as well as the anterior cerebellar arteries arising from the PCA and accessory posterior communicating artery (APCA) and the anterior part of basilar artery, to supply the hemispheres of the cerebellum and the cerebellar vermis.

In this experiment, we aimed to recorded the effect of chronic oral exposure to DEHP on lipid peroxidation and histopathological lesions induced in different organs. A total of 150 quail chick divided into two groups (75 quail’s chicks at each group), control group left without any treatment all time, the second group was orally administrated 5% of DEHP (278.05 mg/kg bw) three times per week and lasted for 60 days. At 30 and 60 days old, a total number of 25 from both groups were euthanized. Blood samples were collected to determine the serum concentration of DEHP and mono ethyl hexyl phthalate (MEHP), liver and kidney to estimate tissue concentration of malondialdehyde (MDA), samples from different organs for histopathological examination. The result showed that the concentration of DEHP and MEHP in blood's serum and concentration of MDA in liver and kidney significantly increased with time in comparison with the control group; besides, oral administration of DEHP induced sever pathological lesions, in brain, aorta, intestines, liver, lung, ovary and testis. In conclusion, the DEHP and its metabolic product MEHP significantly increased in serum and cause significant increase in concertation of MDA in liver and kidney tissues, produces a significant histopathological change in brain, aorta, liver, intestine, lung, ovary and testis that can cause a life-threatening condition.

This study was conducted to determine the prevalence of Sarcoptes scabiei infection in cows in Anbar province, Iraq. The parasite was diagnosed in the laboratory via examining skin scrapings taken from the suspected cows. The results indicated that the infection rate in cows with S. scabiei reached 37.5%, the animals of 3 months - Hammada articulate had a great effect on the parasite, however, the concentration 10 mg/ml leads to the complete disappearance of all parasites and the cure of the infected cows on the 14th day of treatment, which is equal to the drug Abamectin in its effect on the parasites. The current study concluded that cows in the study areas were infected with scabies mites at a high rate, and this calls for finding safe treatment methods by using medicinal herbs and plants because they contain many active compounds that affect the parasite and lead to its mortality, and they are safe strategic alternatives to harmful chemical drugs. This necessitates the establishment of an integrated control approach through treatment with effective plant extracts and to maintain the cleanliness of the animal environment.

The study aims to assess the impact of various doses of red bull on kidney and pancreas of male albino rats. Thirty male albino rats were assigned to three groups (10 animals/ group). Control group (1) received standard diet and water, group 2 and group 3 received daily oral doses of 10 ml/kg/rat and 20 ml/kg/rat of the energy drink (red bull) respectively for 30 days. Under light microscope no tissue changes were seen in kidney and pancreas of control group. In group 2 red bull causes vacuolar degeneration as well as coagulative necrosis of renal tubular epithelium, vascular congestion in the glomeruli and in the interstitial space of the kidney, in addition to atrophy of the glomeruli, as regard to pancreas it causes vascular congestion of the islets of Langerhans, increase in the size of the islets, besides, necrosis of Langerhans cells. In group 3 red bull leads to more atrophic glomeruli, massive coagulative necrosis of renal tubular epithelium, marked vascular dilatation and congestion in the interstitial space and degenerative changes of the renal tubular epithelium, whereas the pancreatic tissue revealed reduction in the size of the islets of Langerhans, vacuolation and degeneration of their cells, necrosis of other islets with mononuclear inflammatory cells infiltration and degenerative changes of pancreatic acini. It is concluded that administration of red bull to rats for 30 days will affect the histological structure of kidney as well as pancreas and this effect is a dose dependent.

This study aimed to diagnose orf virus ORFV from infected goats in Al-Qadisiyah Governorate of Iraq, using polymerase chain reaction and construction of phylogenetic tree. Clinical examination was made on 400 goats in different herds and crusty scabs were collected from forty infected goats. All scabs were subjected to (PCR), sequencing, and phylogenetic analysis involving the presence of GIF gene GM-CSF* inhibitor factor, a characteristic gene of the ORFV. The typical proliferative skin lesion with overall orf prevalence results by PCR was 10% with low mortality rates and high significance variation with age and gender. Two positive PCR amplicons were sent for partial-gene-based sequencing and Phylogenetic analysis. Multiple alignments of sequences presented close identities with two Iraqi global isolates of the virus. This study didn't only report novel sequences from the local orf virus isolates, but it also provides important data about transmission of local sheep orf virus into local goat during closely rearing and grazing and orf outbreak in small ruminant in Iraq might be suspected.

The fly larvae infect the nasal cavities and sinuses (frontal and maxillary) of sheep, goats, and a range of wild ruminants, forming a disease called oestrosis (Nasal myiasis or nasal bot). The disease is one of the significantly diseases for the Iraqi small ruminant industry that causes detrimental economic losses. The current work was carried out to morphologically- and molecularly-characterize O. ovis larvae collected from sheep in a slaughterhouse in Al-Qadisiyah province, Iraq. The study depended on collecting 20 larvae (at different stages) from 20 sheep from 15 October till 17 December 2020. The morphological examination was done using a stereomicroscope and relying on larval characteristic features, including the posterior end, spiracles, and cephalopharyngeal skeleton. The molecular characterization was performed utilizing polymerase chain reaction (PCR) and partial gene sequencing (PGS) methods of the cytochrome c oxidase subunit I (cox1) gene at 700-bp and 300-bp regions. Morphologically, the first-stage larvae (L1) showed characteristic mouth hooks, while the second-stage larvae (L2) revealed clear terminal stigmas. For the third-stage larvae (L3), the color of body segments and their spines' were the most important features for this larval stage. The PCR showed amplification at both regions 700bp and 300bp, in 8 and 7 isolates, respectively. The PGS revealed 15 different local isolates in genetic level aligned with isolates from Kyrgyzstan, Italy, Spain, and Turkey. This study shows the important strain differences of O. ovis that infect the local sheep in Al-Qadisiyah province, Iraq.

The current study was undertaken to record and describe various neoplasms that affect sheep's skin and to determine the relationship between tumor occurrences, age, and sex of the animals. A total number of 12 sheep were examined for abnormal masses in different skin areas including head, eye, ear, udder, teat, the animals age was ranged between 2-6 years. Three different types of cancer were diagnosed in sheep as squamous cell carcinoma, fibroma and papilloma with incidence rates 41.6, 25.1, 33.3% respectively. Neoplasms were recurrent in females more than males and in old ages more than young animals. It can be concluded that the malignant neoplasm especially squamous cell carcinoma was the predominant tumor found in sheep.

There are no prior studies on the pharmacological interaction between nefopam and ketorolac and on their pharmacokinetics in the chickens. The median analgesic effective doses (ED50s) of nefopam and ketorolac were estimated individually as 8.39 mg/kg, i.m. for each drug. Thereafter, their values were determined together in combination as 2.63 and 2.63 mg/kg, i.m. after administration at the ratio of 1:1 of their ED50s. The pharmacodynamic interaction between nefopam and ketorolac was designated as synergistic through the interaction index 0.62. Plasma concentrations of nefopam alone 16 mg/kg, i.m. in different measured times 0.25, 0.5, 1, 2, 4, and 24 hours were 34.07, 31.34, 22.53, 19.03, 14.81, and 10.37 µg/ml, whereas the plasma concentrations increased to become 44.67, 43.52, 45.71, 32.83, 20.96, and 22.54 µg/ml when administered with ketorolac 16 mg/kg, i.m. by 31, 39, 103, 73, 42, and 117 %, respectively. The changes in the pharmacokinetic parameters of nefopam included increases in area under curve (AUC0-∞) 130%, area under moment curve (AUMC0-∞) 210%, mean residence time (MRT) 35%, half-life (t1/2β) 27%, time maximum (Tmax) 300% and concentration maximum (Cmax) 34%, whereas other values were reduced which included elimination rate constant (Kel) 21%, volume of distribution at steady state (Vss) 45% and clearance (Cl) 3%. The net results indicated a synergistic interaction between nefopam and ketorolac in addition to an alteration in nefopam pharmacokinetic parameters which may enhance nefopam therapeutic efficacy in chicks.

Authors reported that exposure to acetaminophen postnatally may be linked to increasing the risk of ASD. However, the reports on its effects on the brain are scanty, and the knowledge concerning their safety is little as there is a traditional left out of the clinical trials by users. The present work tried to elucidate the histological effects of acetaminophen on the hippocampus of neonate male rats after early postnatal exposure. The pups were categorized into2 groups, the control group, and the acetaminophen treated group. The acetaminophen treated animals were injected subcutaneously with acetaminophen of 60 mg/Kg/day from postnatal day (PND) 7 to PND 14, while the control group treated with normal saline with a similar approach. The histopathologic assessment revealed a diminishing in the pyramidal cells layer thickness of Cornue Ammonis. Some areas are devoid of cells with the appearance of Ghost like cells indicating features of neural cell death, degenerated neurons in the pyramidal layer are noticed. Features of nuclear clumping of pyramidal cell layer were shown. Moreover, several changes including vacuolations in the granular layer of DG with disorganization in DG. Neuronal processes presented with clumping. Apoptosis in the granular cells layer and hilus of a section of DG with the appearance of many astrocytes and microglial cells. Exposures to clinically relevant doses of acetaminophen in the postnatal period were shown to affect the histology of rat hippocampal regions, and a balanced risk assessment based on the best professional judgment must be prioritized.

Wild rabbit (Oryctolagus cuniculus) and cape hare (Lepus capensis) are hosts for different flea species and have high medical and veterinary importance, fleas of wild leporids are of special concern since they can act as vectors for diseases, including zoonoses. This study was designed to identify flea species infesting these animals with the description of their epidemiology and the assessment of factors influencing their infestation importance in five provinces located in northern Algeria, to evaluate their implication in the transmission of pathogens. In total, 86 wild leporids were checked from July 2014 to September 2020. Fleas were collected from the fur of animals with tweezers and identified using appropriate keys. The findings showed that 32/86 (37.2%) of animals were infested with fleas. Four flea’s species were identified on cape hares Ctenocefalides felis (51.06% of fleas identified), Ctenocefalides canis 34.04%, Spilopsyllus cuniculi 10.63%, and Archaeopsylla erinacei 4.25%,with a seasonal peak in December. The same, four flea species were found parasitizing wild rabbits Spilopsyllus cuniculi 90.7%, Ctenocefalides felis 4.65%, Ctenocefalides canis 2.32%, and Pulex irritans 2.32%,with the highest importance in March and April. Moreover, this study showed no influence of female gestations on the rate of flea hare infestations. However, S cuniculi rate was correlated with the breeding cycle of the wild rabbits. These findings revealed that, the temperature and the humidity can be important factors that influence on wild leporids flea infestation.

Urtica dioica is used in the many countries as seasoning and as an herbal medicine (antioxidant). In this study, adult male locale rabbit was separated into five groups, Group 1 considered as control, Group 2 to 5 animals were treated with 0.75% ethylene glycol (EG) in water to induce renal and liver damage till 30th day. The group 3 to 5 animals were feed extract of the plant of U. dioica at a dosage of 100 mg/kg body weight from day 15 to the day 30. The extracts were administered twice daily orally. Liver histopathological changes characterized by vacuolar degeneration and coagulative necrosis of hepatocytes, congestion and dilatation of central vein and sinusoids. Renal histopathological changes characterized by deposition of oxalates, blood vessels congestion infiltration of inflammatory cells and change in renal glomeruli in GE treated groups. While histopathological changes in the animals group treated with U. dioica extract and ethylene glycol showed an increase improvement of the histological features of liver tissue, were limited dilatation of renal tubules with less deposition of oxalates, as well as slight infiltration of inflammatory cells in the interstitial tissue. Finally, as a conclusion we noticed that U. dioica extracts had the ameliorative effect of ethylene glycol-induced hepatic and renal histopathological.

Infectious bronchitis disease is becoming the most challenging disease in broiler fields in Iraq. This disease leads to massive economic loss every round of production. Three vaccine strains H120, Ma5, and 4/91 are used to combat the disease during the production period while outbreaks occur continuously. This study aimed to investigates the prevalence and circulation of Mass and 4/91 IBV strains in the broiler fields in Duhok province which is the first record in the area. Positive samples were obtained from suspected flocks to this disease during 2018-2020. A specific region of S1 was amplified using specific pairs of primers. Genotyping was performed by nested PCR using specified primers for detecting both Mass and 4/91 strains. In the results, all of the positive flocks were infected with nephropathogenic strain 793/B or 4/91. Two of the positive flocks had an infection with both Mass and 4/91. These results indicate that more than one strain circulates in the area as well as shows the weakness of vaccines used in broiler fields.

This paper aims to investigate the occurrence of clinical and sub-clinical cases of mastitis in buffaloes, and to identify the differences in the components of the mastitis milk, to facilitate the investigation of a number of epidemiological risk aspects in relation to the occurrence of mastitis and to detect the different bacterial species associated with the disease. Eight hundred buffalo milk samples were randomly extracted from the animals of different ages in Mosul city, Iraq and examined by California mastitis test (CMT) and Ultrasonic milk analyzer. According to the clinical signs and CMT, the results indicated the prevalence of the clinical and subclinical cases of the disease in buffaloes to be 10.62% and 27.37% respectively. There was a substantial rise in the population of somatic cells /ml in both clinical and subclinical cases of mastitis. The risk factors included third trimester of lactation period, old ages 10-11 years, outdoor feeding animals, > 30 buffaloes/herd, northern and southern parts of the city, Spring and Winter seasons. In clinical instances of mastitis, the occurrence of Staphylococcus aureus was 25.88%, Streptococcus agalactiae 18.82%, Streptococcus pyogenes 16.47%, Corynebacterium bovis 14.11%, Escherichia coli 10.58%, Pseudomonus aeruginosa 7.05%, and Pasteurella multocida 7.05%. In the subclinical cases of mastitis, the prevalence of Staphylococcus chromogens was 14.61%, Staphylococcus xylosus 12.78%, Streptococcus agalactiae 11.87%, Streptococcus dysagalactiae 11.41%, Streptococcus uberis 10.04%, Proteus vulgaris 10.04%, Klebsiella pneumonae 9.58%, Escherichia coli 8.21%, Corynebacterium bovis 7.30%, and Pasteurella multocida 4.10%. It is concluded that mastitis leads to a significant reduction in the levels of total solids, lactose, protein, fat, density, and a significant rise in the levels of pH values and electrical conductivity of the milk samples of clinical and subclinical cases of mastitis.

Cutaneous myiasis is the infestation of larvae of flies in the vertebrate. The condition causes significant economic losses to the livestock industry indicating the importance of a systematic approach to clinical management. The incidents of two episodes of severe cutaneous myiasis wound at the base of the antler in a 5-year-old semi-intensively managed male Dama dama deer was described. Physical examination revealed a foul-smelling necrotic wound around the left cornual region measuring 5cm×4cm in radius and 3cm in depth and fly eggs were seen on the surface of the wound. The clinical findings suggest the diagnosis of a severe cutaneous myiasis. The case was managed by wound debridement and flushing with hydrogen peroxide 3% and diluted hibiscrub 0.05%, followed with povidone iodine 2.5%. Topical ointment, Dermapred® and insecticide, Negasunt® were applied topically. Parenteral administration of flunixin meglumine 2.2 mg/kg for 3 days and Oxytetracycline 1 ml/10 k every 72 hours, given twice both through intramuscular route. Supplement injections, Vitavet® and Catosal™ were given to improve the wound healing process. The outcome of the wound improved post-14 days of treatment. Administration of timely combination of antimicrobials, pain management and flies control are leading factors to a good healing process.

A Lambda-cyhalothrin (LTC) is classified as a synthetic type II pyrethroids, available in the local market, used to eliminate insects, which is widely used for spraying homes. This study aims to reveal the acute and subacute toxic effects of LTC in chicks as a biological model. The acute (LD50) by up and down method recorded through 24 hrs. The signs and toxicity scores were estimated, the sub-acute toxicity effects of LTC in the open-field activity and tonic immobility test, body-weight and histopathological effects were recorded. The oral LTC LD50 in chicks was 228.5 mg/kg. Oral administration of LTC at doses 57.12, 114.25, and 171.36 mg/kg, which represented 25%, 50%, and 75% of LD50 respectively, caused signs of toxicity such asdepression with wing dropping, feathered by closed eyelids, gasping, and recumbency. LTC causes a significant decrease in chick’s weight, locomotor activity in the open field activity represented by increase latency to move, and decrease the number of lines crossed. The liver and brain show histopathological changes such as congestion, focal infiltration of mononuclear cells, hemorrhage, coagulative necrosis, and vasogenic edema. In the brain, the lesion was represented by shrunken in purkinji, demyelination of axon and hyper atrophy of astrocyte, the lesion was more severe in both organs when exposed to a high concentration and for longer periods. Our results demonstrated that LCT has a moderate toxicity in chicks, and causes behavioral and histological toxic effects, especially with sub-acute toxicity. Therefore, we do not recommend using it, and restricted application in homes and agriculture.

D-ɑ-tocopheryl polyethylene glycol succinate (Vitamin E TPGS or TPGS) has been approved by food and drug administration (FDA) as harmless adjuvant and is largely used in drug systems delivery. Physicochemical and biological possessions of TPGS provide many advantages for its usage in drug delivery, such as high bio-compatibility, increased drug solubility, improved drug penetration and selective anti-tumor action. The aim of the study was to use the TPGS polymer as a drug release model to regulate the release of the anesthetic xylazine-ketamine in order to minimize therapeutically reference dose, avoid side effects, and improve efficacy. The study performed on 15 adult local breed male rabbits, divided into 3 groups with same number which injected intramuscularly with single dose of suggested anesthetics. Group 1 injected with ketamine and xylazine. Group 2 injected with ketamine and xylazine as same dose of group 1 loaded by PLGA-TPGS. Group 3 injected with Ketamine and xylazine loaded by PLGA-TPGS with half dose of Group 1 and 2. The following physiological parameters were evaluated: heart rate, respiratory rate, degree of muscle relaxation, onset of action and stages of anesthesia before administration the drug at time zero then at 10, 30 and 60 minutes after drug administration, also induction of anesthesia, surgical anesthesia and recovery time were recorded. Nanoprecipitation technique was optimal method for preparing small particle size as well as reduce dose for therapeutic effect. Small and large dose was showed perfect analgesic and muscle relaxant activity of xylazine-ketamine drugs. Ketamine 30 mg and xylazine 10 mg loaded PLGA showed elevation of conciseness period as well as increase muscle relaxant. Ketamine 30 mg and xylazine 10 mg loaded PLGA reduce heart rate but onset of action delayed when compared with reference drug. The process of nanoprecipitation was ideal for forming small particle sizes and reducing the dosage for therapeutic effects. PLGA loaded with ketamine-xylazine demonstrated improved cycle concentration (walk time) as well as improved muscle relaxant, finally the protocol created an excellent anesthetic combination for induction of general anesthesia.

Lameness is one of the most prevalent and costly maladies affecting dairy cattle. It has been ranked as the third after mastitis and reproductive failure. One of the leading causes of lameness is corium tissue damage and hence claw horn lesions development. Flooring system was found to have an impact on the development of such lesions. Therefore, the objective of the present study was to study the effect of flooring system on the development of four non-infectious claw disorders in Egyptian dairy farms. Another objective was to study the effect of claw disorders on reproductive performance and total milk production. Four dairy herds with earthen floor (n=2) and desert floor (n=2) from Ash-Sharkia and Ismailia Provinces were included in this study. Results revealed that the prevalence of white line disease (WLD) was the highest among recorded lesions in earthen floor farms (2.7%) followed by sole ulcer (SU) 2.1% and sole abscess (SA) 1.7% then vertical wall fissures (VWF) 1.6%. While in the desert floor farms, VWF and SA were reported in 0.8% of animals followed by WLD and SU in 0.4% and 0.3% of animals, respectively. The non-infectious claw disorders were detected mainly in hindlimbs in earthen floor farms when compared to forelimbs (6.6% and 1.5%, respectively) while in the desert floor farms were nearly equal for the forelimbs (1.1%) and hindlimbs (1.2%). In conclusion, the animals housed in earthen floor farms were more susceptible to non-infectious claw disorders than those housed in desert floor.

This study was conducted to qualify the ameliorating potency of silymarin against toxicity in ethidium bromide (EtBr) treated female rats. Eighty female Wistar rats aged 100 days, weighted 170-175 g were randomly allocated to control, orally supplemented with drinking water, and three treated groups, orally supplemented with silymarin 200 mg/kg BW, EtBr 10 mg/kg BW, and combination of EtBr and silymarin (SEtBr), respectively. Each group was allocated to two subgroups, sacrificed after 20 and 40 days of treatment. Bodyweight gain, uteri, and ovaries weight were recorded. Ovarian samples were obtained for histopathological examination. EtBr group females recorded the lowest body weight gain, relative weights of ovaries and uteri, and ovarian follicle number, whereas S group females recorded the highest body weight gain and follicular number, while the ovaries and uteri weights were either higher or close to the control group, at both experimental periods. Histopathological findings of both periods revealed necrosis, cirrhosis, ischemia, and prominent hemorrhage in the blood capillaries in EtBr treated ovarian tissues, but many of the ovarian follicles being mature and the atretic follicles were hence found to be high in number, whereas silymarin treated females showed normal ovarian tissues and viable ovarian follicles as that in control females. The combination-treated females, at 20 days, revealed necrotic primary ovarian follicles with some macrophages infiltration, whereas 40 days’ period showed normal ovarian cortex, medulla, and ovarian follicles. In conclusion, silymarin treatment in combination with EtBr has a potent amelioration effect against ovarian toxicity, in a duration-dependent manner.

The study aimed to investigate if taurine could help reduce sodium fluoride-induced toxicity in chicks. The chicks in this study were divided into four equal groups, each with eight chicks: the control group, sodium fluoride 20 mg/kg group, taurine 3 g/kg group, the fourth group was dosed with each of the sodium fluoride 20 mg/kg and taurine 3 g/kg groups all groups were dosed orally. The dosing was set at 5 days/week for 4 weeks. After 2 and 4 weeks of treatment, the group treated with taurine alone or with sodium fluoride showed an improvement in neurobehavioral and motor activity, as evidenced by a reduction in the duration of chick immobility in the immobility test and an increase in the number of squares cross in the open field test compared to the group treated with sodium fluoride alone. The level of ALT enzyme and calcium in the group treated with sodium fluoride increased significantly compared to the control and taurine group alone, and with sodium fluoride, AST and creatinine levels increased significantly after 4 weeks of sodium fluoride treatment compared to the other groups. When it came to measuring malondialdehyde and glutathione, the sodium fluoride group alone showed a significant increase in malondialdehyde and significant decrease in glutathione after 2 and 4 weeks of treatment when compared to the control and the other groups. The histopathological examination confirmed the previous findings, with the histological sections of the liver, kidney, and brain showing a significant improvement in the group treated with sodium fluoride and taurine after four weeks of treatment. We conclude from this study that taurine has a clear therapeutic effect against oxidative stress, as evidenced by behavioral and motor behavioral effects, as well as levels of glutathione, malondialdehyde, and liver function enzymes, and serum creatinine, as well as histopathological examination of the brain, kidneys, and liver.

The study was conducted to evaluate the application of transabdominal ultrasonography for the determination of pregnancy and fetal viability in Iraqi buffaloes. Thirty-two buffaloes at different periods of gestation were included. The buffaloes were palpated transrectally and transabdominal ultrasonography was applied to determine the pregnancy and fetal viability status. The accuracy, sensitivity, specificity, the positive and negative predictive value of transrectal palpation were 93.7, 100, 83.3, 90.9, and 100%, and for transrectal palpation were 78.1, 100, 58.8, 68.2, and 100%, respectively. The values of accuracy and specificity in the first trimester obtained by transabdominal ultrasonography were lower than those obtained by rectal palpation (66.6 vs. 94.4% and 62.5 vs. 90.9%), whereas the same values of accuracy and specificity were at second and third trimesters. Notwithstanding the values of the transrectal palpation and transabdominal ultrasonography sensitivity were 100% in the three trimesters of buffalo’s gestation. At the first trimester of gestation, transabdominal ultrasonography required more time in comparison to transrectal palpation to get the final decision. Conversely, transrectal palpation required more time than transabdominal ultrasonography to diagnose the pregnant buffalos which were at the second and third trimesters of gestation. The transabdominal ultrasonography pregnancy diagnosis in the third trimester was faster than at the second and first trimester, a highly significant (P<0.001) negative correlation was reported between the time required for pregnancy diagnosis and the gestation age. It can be concluded that the transabdominal is a practical approach of ultrasonography for pregnancy diagnosis and determination of fetal viability in buffalo cows especially at the second and third trimesters of gestation.

The current study intends to look at the impact of the fluoxetine hydrochloride on specific tissues lung and pancreas of mature pregnant mice. The two doses used during the study were 45,75mg/kg b.w. from the 7th to the 17th day of pregnancy. Experimental animals received fluoxetine orally at a dosage of 45mg/kg b.w. The findings indicate variable pathologic changes in the lungs. At the dose of 75 mg/kg b.w. hyperplasia of pneumocytes occurred. In the pancreas, there were no detectible lesions at the dose of 45mg/kg b.w. while at the dose of 75 mg/kg b.w. the severity of tissue lesions was seen. In conclusion, antidepressants may stimulate oxidative injury throughout the body's internal organs, particularly if taken at high doses during pregnancy. Consequently, these lesions have a great impact on the heath of both fetus and pregnant mice since the most common lesions were observed in fetus which cause abortion which effect on the health of pregnant mice.

In the current study, the potential effects of the Nokia mobile device were studied with frequency 900-1800 Mhz on the eyes of pregnant and non-pregnant female Swiss mice. The mice were divided into three groups: The first group is a control group consisting of five mice, the second group consists of 10 mice and the third group consists of 10 pregnant mice. Female mice of the second and third groups were exposed for a 3 hour / day and for a 30 days to a mobile device. After the end of 30 days, mice were euthanized and tissue samples were taken from the eyes of pregnant and non-pregnant mice. Microscopic examination showed, that there are significant effects on the cornea and retina of the eye, especially in pregnant females, which supports the current studies conducted on the effect of mobile phones on the eyes represented by vascularization where some sections showed newly formed blood vessels in stroma layer just beneath bowman's membrane and retina degeneration. This study concluded that the exposure to the mobile radiation led to serious histological changes in the tissues of eye which may lead to blindness.

This evolution-based study aimed to reliably identify the epidemiological prevalence of Escherichia coli that wasrecovered from affected milk of cattle by mastitis, study the evolution of this bacterium, and describe some isolates using polymerase chain reaction (PCR) technique and DNA sequencing. Here, we collected 50 cattle milk samples and submitted them to conventional bacterial isolation and identification using enrichment culture method and biochemical tests. Then, we confirmed the results by PCR technique based on 16S ribosomal RNA gene. The results showed that E. coli was isolated from cattle at (36%), and this was confirmed by PCR that showed highly specific detection of E. coli isolates at (100%). DNA sequencing of partial 16S ribosomal RNA gene showed (99%) homological identity with NCBI-Blast E. coli isolates and the phylogenetic analysis showed genetic similarity (0.5 genetic changes). In conclusion, this was the first study in Iraq to report genetic relationship between E. coli isolated from milk of mastitis-infected cattle. Therefore, it is essential to define the role of animals as an important source in the distribution of some pathogens that are related to public health.

Hypodermosis is a distinctive ectoparasitic disease infesting cattle; Hypoderma bovis and Hypoderma lineatum are the most common causes of this myasis. In this study 78 larvae were collected from infected cattle by extraction in the Educational Veterinary Hospital, from Kokjali and Bazwaya flocks and from the skin of slaughtered in Mosul abattoirs for the period from October 2020 to March 2021. Morphological identification by using stereomicroscope depending on patterns of spinulation of the 10th abdominal segment and peritremes structure of L3 classified as H. bovis and H. lineatum. Molecular technique by traditional PCR applied on 16 L3 of the genus Hypoderma revealed that the reaction product was 500 bp by amplification of mt CO1 gene while the results of PCR-RFLP using restriction TaqI enzyme for differentiation between the two species indicated reaction products 300bp for H. bovis and 200bp for H. lineatum respectively. The results of molecular analysis by PCR and PCR-RFLP proved the existence of these two species of Hypoderma in Mosul.

To investigate the effects of systemic administration of Theranekron (Tarantula cubensis) extract as homeopathic remedy on anastomosis healing after surgical intestinal resection. Eight healthy stray dogs (age 1-1.5 years, weight 15-20 kgs) were randomly divided into two groups; control (4 animals) and treatment group (4 animals). Intestinal resection and anastomosis were performed in all animals in both groups. Theranekron D6 (3 ml) was administered subcutaneously one week before surgery and at operation time in the treatment group whereas animals of the control group were injected 3 ml of normal saline at the same time points of treatment group. All animals were kept for 15 days following surgery and a segment of intestine was removed for histopathological and press pressure measurement. The results showed that no post-operative complications have been observed in both groups. The gross examination of the anastomosis site revealed sever adhesions with omentum and other intestinal segment of the all animals of the control group in comparison to the treatment group where lesser adhesions with omentum without any adhesion with the other intestinal segment have been noticed. There was slight difference between control and treatment group in relation to histopathological examination. In conclusion, the findings of this study showed that Theranekron was able to improve the healing process of the resected and anastomosed intestinal segment

This work was aimed to explore the details of the ion channels gating and there physiological role in sperm in the future.Mouse spermatozoa express a pH-dependent K+ current (KSper) thought to induce hyperpolarization to enhance Ca2+ influx via alkaline-activated calcium channel (Catsper) to initial a so-called sperm capacitation by NH4Cl during travelling in female genital tract for fertilization. However, the regulating mechanism of the Ksper and Catsper channels by membrane potential and pHi remains uncertain, because the complexities of two channel kinetics in sperms is hardly to be overcame at this stage. Here we show that difference of the intracellular [Ca2+]i between the wild type (Wt) and knockout (KO) Ksper (or Slo3/) mice in the application of the Slo3 blockers, Guinidine (QD) and Clofilium, and NH4Cl, indicating that Ksper channels, encoding Slo3 gene, dominates the membrane potential of mouse sperms to increase the intracellular [Ca2+]i and [pH]i during the capacitation process to play a vital role in fertility. Furthermore, a HH model sperm built directly with the native Ksper and Catsper currents in sperms reveals two functions of membrane potential and intracellular pHi, allowing us to calculate the intracellular pHi by NH4Cl, based on membrane potentials recording from current-clamp experiments. During modeling, we found a caton channel with Vrev= +20 mV in mouse sperm from the double-KO (i.e. Catsper-/- and Ksper-/-) mice, which is definitely necessary for a model able to match the data.

The disaccharides, consisting of sucrose, lactose and maltose, are hydrolysed into monosaccharides (D-glucose, D-galactose and D-fructose) by intestinal brush border enzymes: sucrase, lactase and maltase. The aim of this study to investigate changes in the brush-border membrane carbohydrate digestive enzymes. From intestinal mucosal scrapings of equine, brush border membrane vesicles were isolated. The results showed that sucrase, maltase and lactase are present in the equine small intestine. The activity of all three enzymes is highest proximally (in the duodenum and jejunum) and lower in the ileum. There was considerable variation between individual horses, however the majority showed highest disaccharidase activity in the jejunum, with some showing highest activity in the duodenum. Sucrase activity is highest in the jejunum and duodenum and lower in the ileum. Maltase activity is similar in all three regions, but slightly higher in the jejunum. Lactase activity is low in all three regions of the small intestine, slightly higher in the equine jejunum and duodenum than ileum. From this study, we can conclude that the equine small intestine digests disaccharides by the brush-border associated disaccharidases sucrase, maltase and lactase. Levels of sucrase and lactase are comparable to other species, but maltase is much higher.

The present study was aimed to determine the scolicidal effect of stem and root alcoholic extract of Punica granatum L. (Pomegranate) on the viability and fatty acids content of Ecinococcus granulosus protoscolices. The study elucidate the scolocidal effect of both stem and root extracts. Its seemed that the scolocidal effect of root extract was higher than that of stem extract ie. LC50 and LC90 of stem extract were 5 and 9 mg/ml respectively while LC50 and LC90 of root extract were 3 and 8 mg/ml respectively. GLC analysis of E. granulosus protoscolices was stated presence of nine fatty acids esters, which were Lauric (C12:0); Myrisitic (C14:0); Palmatic (C16:0); Stearic (C18:0); Archidic (C20:0); Behenic (C22:0), which were saturated fatty acids, and Oleic (C18:1); Linoleic (C18:2); Linolenic (C18:3) which were unsaturated fatty acids. Treating E.granulosus protoscolices with LC50 of pomegranate stem bark was showing slight and swing effect on fatty acid content, while treated the protoscolices with LC50 of root bark were resulted in obvious increase in short length fatty acids like Lauric, Myrisitic and Palmatic in compare with control group. In contrast the long chain fatty acids concentration like Oleic, Linoleic and Linolenic were decrease.

Pseudomonas (P.) aeruginosa possesses a variety of the virulence factors that may contribute to its pathogenicity, such as exotoxin A (toxA) and exoenzyme S (ExoS). The principal aim of this study was to find out the rapid method for identification of P. aeruginosa and to detect the toxA, exoS and16SrRNAgenes by Polymerase Chain Reaction (PCR) technique. Other aim on the other hand, the DNA sequencing was performed for phylogenetic tree analysis of 16SrRNA gene in local pathogenic P. aeruginosa isolates in comparison with NCBI-Genbank global P. aeruginosa isolates and finally submission of the present isolates in NCBI-Genbank database. According to the detection of the 16S rRNA gene, the study revealed that 29 (58%) and 32 (64%) of P. aeruginosa out of 50 swabs obtained from each wound and burn areas were positive. whereas in addition, the result of this study showed that the toxA gene was detected in 77% of P. aeruginosa isolated from the wound and 51% of P. aeruginosa isolated from the burn. whereas, the exoS gene was detected in 69% of P. aeruginosa isolated from the wound and 49% P. aeruginosa isolated from the burn. BLAST analysis showed that the 16S rRNA gene shared more than 99% homology with the sequences of P. aeruginosa. Furthermore, the phylogenetic tree analysis of the 16S rRNA gene indicated that (PA-IQw and PA-IQb) the 16S rRNA gene shared higher homology with other four P. aeruginosa isolates available in the GenBank. The homology of the nucleotides was between 99.9% and 100%.

Research was undertaken to establish an inventory of ticks on dogs in the north east of Algeria. In the first aspect of study, a survey aims to identify of Ixodidae infesting the dogs in bioclimatic different areas and to determine the risk factors. This work took place between 2006 and 2012. The results of the collections show that all the dogs, which were the subject of this survey, are infested by ticks during the period between March and August in different areas of the northeastern of Algeria. Rhipicephalus sanguineus is the predominant tick species. It has been observed with a frequency of 88 % in the area of El-Tarf, 100 % in Souk-Ahras, 95 % in the Tébessa region and 72 % in Guelma, (average of 89 %). Climatic conditions seem to play the essential role for this distribution of ticks. The other tick species collected are: Ixodes ricinus, Rhipicephalus turanicus, Haemaphysalis punctata and Hyalomma anatolicum. The latter were present with very low a proportion, which gives them the appearance of accidental parasitism in dogs. Rhipicephalus sanguineus has significant infestation intensity in spring and summer, peaking in August in the semi-arid region (Souk-Ahras). In humid regions (El-Tarf), the peak of infestation recorded by this arthropod is in April. The second aspect of study of the seasonal dynamics of Rhipicephalus sanguineus shows the seasonal nature (Spring-Summer) of the brown tick of dog.

The aim of this work is to study lamb births and mortalities in Algerian sheep Ouled Djellal breed distributed in different zones of Tébessa region, which is divided according to bioclimatic stage, staff in livestock and area agricultural vocation, into four distinct zones: northern (A, B), middle (C) and southern zone (D). During two years 2015-2016, birth numbers (BN) and mortality rates (MR) of 355 sheep flocks were recorded using a questionnaire. Concerning BN the total number was 21244 lambs representing a mean 59±31 per flock. No significant differences between the birth means of C and D (75±28 vs 83±30) were registered. Birth mean was significantly higher (P<0,05) in B (40±17) than A (29±10), when comparison with C and D, the births of A and B were highly significantly (P<0,001). According to (BN) the studied region were classified into 3 zone groups: (a) with high lambing rate (C, D); (b) with medium lambing rate (B); (c) with low lambing (A). In regard to mortality rates, the total rate was 24±6%. The (MR) in A (27±5%) was significantly higher (P<0,05) as compared to other zones (B) 24±4%, (C) 23±7% and (D) 22±4%. However, no significant differences between B, C and D were revealed. According to the results of (MR) the studied region was classified into two groups: (a) with low MR (C, D), (b) with high MR (A, B). Our result showed that zones influence the (BN) and (MR) in Tébessa region, and southern zones especially D seems the appropriate to practice breeding of Ouled Djellal breed.

This study aimed to investigate the impact of supplementing different levels of Nigella sativa oil in rations of growing lambs. In a feeding experiment lasted 90 days, 18 growing Ossimi lambs (6-7 months old) were randomly divided by weight into three equal groups (6 animals each). Individual animals in all groups were fed a uniform total mixed ration, offered at 3% of body weight, where the first group was without supplement (R1), while Nigella sativa oil was supplemented at 0.1 (R2) and 0.2% (R3) of dietary DM. Results indicated that additions of N. sativa oil didn’t influenced feed intake, but it increased average body weight gain and feed efficiency. Nutrients digestibility values and dietary nitrogen utilization were higher with N. sativaoil rations than control. Ruminal fermentation parameters showed comparable pH values among groups at 0, 3 and 6 hrs. of feeding. Ruminal NH3-N concentration was lower and TVFA concentration was higher for animal fed R2 and R3 rations than control. It’s concluded that N. sativa oil could be added at 0.2 % of the daily feed as a natural growth enhancer of lambs.

COVID- 19 is highly infectious disease where the first infected case reported in Wuhan city-China, then it was spread worldwide. The causative agent belongs to novel enveloped single linear positive-sense stranded RNA Coronavirus, which is also called SARS-CoV-2 and has an affinity to lung cells. The genetic analysis of SARS-CoV-2 suggested that this novehtm hgn l strain may be developed from the animal. origin by recombination between a bat SARS-like CoV and a coronavirus of unknown origin. The ability of rapid spread of SARS-CoV-2 virus from person to other is similar or even more than to other human viruses like influenza or plague leadding to be announced as a pandemic by WHO in 2020. The mortality rate in SARS-CoV-2 increased day by day and this led the scientists to search ways to control the virus. Most of the deaths in aged patients may be due to immune response complications where 70% of patients showed lymphopenia. This review, provided some details about structure, pathogenicity and immune response against SARS-CoV-2. The facts in this review lead to suggest that in most cases the death in SARS-CoV-2 may occur via loss of systemic inflammatory response control which leading to lung injury followed by pneumonia, acute respiratory distress syndrome (ARDS) and respiratory failure, hence the death especially in old patients. In concluding the early effective control of both innate and adaptive immunity may be the critical. key factor in protection against SARS-CoV-2.

Data of twenty one local breed bull calves (Sharabi and Janoubi) were collected from previous work for this study, their ages ranged from 8-18 month with initial live body weight of 125-300 kg. They were fed for 100 days period a standard ration which consisted of 60:40% concentrate to roughages ratio and contained 12.4% crude protein, 19.9% crude fiber and 2.2 Mcal/kg ME. Feed was offered at 3% of live body weight. Calves weights were sorted out into three groups, according to their means of body weight and were 140, 210 and 280 kg. The first group of calves had a significant increase daily gain more than the other two groups and were 1200, 850 and 830 g, respectively. Also, feed conversion rate of the first group was better than the other two groups, and were 6.2, 8.9 and 9.9 kg. ration/1 kg weight gain, respectively. Cost of feeding to produce one kg of weight gain in the first group was more efficient than the other two groups, and were 1860, 2670 and 2970 I.D., respectively. No differences were found in carcass traits among the three groups of calves. The results of this study suggest that it is better to choose local bull calves at live weight less than 200 kg for fattening purpose, to obtain more economical benefit.

The present study was conducted on 57 local breed cows suffering from various degrees of endometritis. The clinical examination included visual examination of vagina supported by uterine palpation per rectum; the laboratory examination included the bacterial isolation from the uterine swabs and histopathological examination of the uterine biopsies. Animals were randomly divided in to three groups of 15 cows each and 12 cows were considered as a control group received no treatment and observed for three consecutive estrous cycles. The first group was treated with a mixture of oxytetracycline (4 g) and tylosin (2 g), second group was treated with cephquenome sulfate 0.5 g, and the third group was treated with lugol's solution (30 ml) 2 %. These treatments were applied as a single intrauterine infusion and the clinical recovery was evaluated at the next estrous cycle by considering the absence of abnormal vagina discharge as an indicator of clinical recovery. Cows that showed clinical cure were inseminated artificially and the pregnancy diagnosis was preformed at least 75 days after insemination by rectal palpation. Retained placenta was the most important predisposing factor of endometritis 50.8 %, results of the bacterial examination demonstrated that E. coli was the most prevalence bacteria (27.4 %). Histopathological examination of uterine biopsy showed a high incidence ratio of chronic endometritis (42.1 %). Results of the treatment showed a higher response and conception rate in the second group (using of cephquenome) 73.3 % and 63.3 %, respectively, followed by first group (using mixture of oxytetracycline and tylosin) 60 % and 55.5 %, respectively, then the third group (using of lugol's solution) 40 % and 50 %, respectively. The lowest cure and conception rates were observed in the control group 25 % and 33.3 %, respectively. This study pointed out a positive relationship between the nature of the vaginal discharge and each of the bacteriological and histopathological examination and revealed the importance of the early treatment of endometritis especially using of cephquenome sulfate.
