Fladioimmunoassay technique was used to determine the concentrations of progesterone in serum, fore-milk and saliva of 40 Nili-Ravi buffaloes during pro-oestrus, oestrus, met-oestrus and di-oestrus. Progesterone concentrations during oestrus were uniformly lower in all experimental body fluids; the highest concentrations were found during the mid luteal phase. Although the hormonal trend was si...

The present study was conducted to see the effect of non-specific genital infections and ovulatory disturbances on clinical signs of oestrusnamely oestrus duration, tonicity of uterus, relaxation of cervix and persistence of follicle. The mean values of oestrus duration, tonicity of uterus and relaxation of cervix varied significantly (P

This experiment was conducted to determine the reproductive performance of Arabian ewes treated with short and long-term progesterone devices in addition to low doses of equine chorionic gonadotropin (eCG) during the anoestrus season. A total of 36 ewes were divided into three groups: in group I vaginal sponges (60 mg medroxy progesterone acetate; (MAP)) were applied and removed after 6 days; i...

Buffalo reproduction is considerably affected by late maturity, poor oestrus symptoms and long postpartum periods. This study was undertaken to evaluate the efficiency of Eazi Breed controlled internal drug release (CIDR), an intravaginal progesterone-releasing device, in relation to oestrus and fertility. Five hundred true anoestrus buffalo cows, in the age group 4-6 years in 10 villages of Dh...
