Abstract
The study was conducted on 641 Iraqi Awassi ewes suffering from dystocia ( n = 332), uterine prolapse ( n = 125), retained placenta ( n = 110) and postpartum metritis ( n = 74). Procedures for treatment of different types of dystocia were manual (correction and traction) ( n = 146), pharmacological ( n = 48) and surgical (Caesarean section) ( n = 138). Efficiency of each method of treatment was: 75.3%, 66.6% and 86.9%, respectively, with a difference ( P < 0.01) between methods. Ewes with uterine prolapse were treated by repositioning and suturing of the vulva for 3–5 days. Good prognoses were obtained in 80% ( 100 125 ) of the cases. Animals affected with retained placenta were treated by manual removal of placenta plus long acting (LA) oxytetracycline 20% i.m. ( n = 37) or 2 mg oestradiol benzoate i.m. plus 20 IU oxytocin i.m. ( n = 37) or 10 mg prostaglandin F 2α i.m. ( n = 36). Good response was obtained (91.6%) with PG F 2α treatment. Manual treatment, antibiotics and oestradiol benzoate plus oxytocin had a response of 54.8% and 67.5%, respectively. There was a difference ( P < 0.01) between prostaglandin-treated and other groups. Ewes with postpartum metritis were treated: Group 1 ( n = 25) 20 mg per kg body weight (BW) L.A. oxytetracycline i.m.; Group 2 ( n = 250 20 mg kg −1 BW L.A. oxytetracycline i.m. plus oestradiol benzoate (2mg i.m.) followed by 20 IU of oxytocin i.m.; Group 3 ( n = 24) 10 mg prostaglandin F 2α i.m. plus 20 mg kg −1 BW L.A. oxytetracycline i.m. High success was obtained (91.6%) in the third group, while the responses were 60% and 76% in the first and second groups, respectively, with a difference ( P < 0.01) between groups. It was concluded that Caesarean section was the most successful procedure for treatment of dystocia. It was also documented that injection of PG F 2α or oxytocin plus oestradiol alone or in combination with antibiotics directly after parturition reduced morbidity from retained placenta and postpartum metritis.
