A study was conducted to assess the effect of weaning age on post-weaning reproductive performance of crossbred sows. A total of eighteen crossbred sows were selected and weighed at 110th day of gestation and farrowing. After weaning these sows were weighed and divided into three groups based on weaning age as Group-I (28 days of weaning age), Group-II (42 days of weaning age) and Group-III (56 days of weaning age). The body weight loss of sow due to lactation per piglet was significantly (P˂0.01) higher in Group III (3.12 ± 0.17) compared to Groups I (1.63 ± 0.13) and II (2.14 ± 0.17). Weaning to estrus interval is significantly (P˂0.01) lower in Group I (5.16 ± 0.54) compared to Group III (12.50 ±1.72) and did not differ with Group II (9.33 ± 0.95). Sows in Group I (151.50 ± 3.72) are with lowest and Group III (183.00 ± 1.71) with highest farrowing intervals. Litter size on subsequent farrowing was slightly higher in group III (10.16 ± 0.30) compared to Group II (9.50 ± 0.42) and lowest in Group I (9.33 ± 0.71). Based on the findings we can conclude that sows in Group I and II have better reproductive performance compared to Group III.
