Abstract

The study was conducted on 76 Friesian-Holstein cows suffered from RFM, that presented in Al- Fayha station out of 822 cows. The cows included in this study aged 3-7 years and calved 1-5 times. The cows were divided into four groups; the 1^st group (20 cows) treated with PGF₂α 22.5mg/ i.m., the 2^nd group (20 cows) treated with oxytocine 50 I.U/i.m. plus Estradiol Benzoate 4mg/ i.m., the 3^rd group (16 cows) treated by manual removal with antibiotic therapy (oxytetracyclin 20mg/kg/ B. W), the 4^th group (20 cows) received no treatment and serve as a control group. The results showed that the incidence of RFM was 9.2%. RFM were more likely to occur following; male calving, calf death, abortion and dystocia. The incidence of RFM was greatly affected by the age of animal, number of calving and season. The results of treatments showed that injection of PGF₂α was more effective in treatment of RFM in comparison with the other regimen of treatments that used in this study.
