Abstract
ABSTRACT
A total of 29 sows (14 LWY, 7 HS and 9 BB) sows were studied for a period of 11
months under the field condition of Aizawl district, Mizoram. The average weaning to estrus
interval (WEI) of sows was found to be 13.52±3.35 days. The WEI in Large White Yorkshire,
Hampshire and Burmese Black was found to be 17.43±6.24, 7.67±0.49 and 12.00±5.21 days
respectively. However, there was non-significant difference among the three breeds i.e Large
White Yorkshire (LWY), Hampshire (HS) and Burmese Black (BB).
Key words : Weaning to estrus interval, sows, field condition.
