The present study was conducted to see the effect of non-specific genital infections and ovulatory distur-bances on clinical signs of oestrus namely oestrus duration, tonicity of uterus, relaxation of cervix and per-sistence of follicle. The mean values of oestrus duration, tonicity of uterus and relaxation of cervix varied significantly (P < 0.05) among the group of impaired ovulation (anovulation and delayed ovulation) and normal ovulation. Following the onset of oestrus, follicle was palpated up to 144 hrs in all anovulation ani-mals, 72.00±4.17 hrs in case of delayed ovulation, 36.89±0.62 hrs in case of normal ovulation with infec-tion and 36.71±1.61 hrs in the control group (normal ovulation without infection). The study revealed that oestrus duration and status of reproductive organs are important criteria in the diagnosis of ovulatory dis-turbances in repeat breeding cattle.
