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<0.05) amongthe group of impaired ovulation (anovulation and delayed ovulation) and normal ovulation. Following the onset of oestrus, follicle was palpated up to144 hrs in all anovulation animals, 72.00±4.17 hrs in case of delayed ovulation, 36.89±0.62 hrs in case of normal ovulation with infection 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 disturbances in repeat breeding cattle.
