The present study was conducted with the objective to determine the effect of continuous buck exposure on the postpartum resumption of ovarian activity, first behavioural oestrus and conception rate in Malabari crossbred does. A total of 20 does on day 31 postpartum were selected and were randomly allotted into two groups. Buck exposed (BE) does (n=10) were in continuous exposure to bucks throughout the study period whereas the control (n=10) group were not exposed to buck. Both groups were kept under similar feeding and management conditions. The animals were weaned on day-30 postpartum, the time interval from the weaning to the first behavioural oestrus ranged from 33-41 postpartum (3-11 days) in BE and 48-72 postpartum (18- 42 days) in control animals (P<0.05). During the study period, in both the groups, an oestrus response of 100 per cent was observed within
72 days. The conception rate in BE and control were 50 and 30 per cent, respectively (P>0.05).It was concluded that, does in continuous exposure to buck showed reduced intervals from the weaning to first behavioural oestrus, earlier resumption of cyclicity and improved conception rate compared to the control group.
