Abstract

The study was conducted on 97 native goats, 2-4 years old, from both sexes, animals were examined clinically and 15 clinically normal native goats served as control, the others 82 native goats naturally infective with blood parasites were divided into three groups according to hematological and biochemical tests, 30 were infected with Babesia motasi, 24 were infected with Anaplasma ovis and 28 infected with Theileria hirci (Th.lestoquardi). Results indicated that blood parasitic infection affected blood parameters as total red blood cells, haemoglobin concentration, packed cell volume significantly decreased, beside the significant increase in the erythrocytes sedimentation rate and anemia of different types were also recorded depending on the type of infection. Total platelets count significantly decreased, while there was significant increase in mean thrombocytes volume as well as significant decrease in fibrinogen, significant increase in clotting time, prothrombin time and activated partial thromboplastin time were also recorded. Biochemical changes showed significant decrease in serum total protein and serum calcium values specially in goats infected with Babesia motasi. Infection with B. motasi has an adverse effect on blood clotting indices in comparison with other blood parasitic infections.
