Body condition score at lambing did not affect the resumption of ovarian and estrous activity in lactating Pelibuey ewes

The aim of the study was to evaluate effect body condition score (BCS) at lambing over resumption ovarian and estrous postpartum activity in lactating Pelibuey ewes. Twenty ewes were assigned two groups, according BCS lambing: Low (LBC, n = 10) High (HBC, 10). Ovarian activities daily monitored from day 3 until first or 90 days postpartum. Continuous variables analyzed using Student´s t test binary responses with exact Fisher test. No significant on estrous, interval, length, cycle preovulatory follicles maximum follicular diameter ovulation rate observed. However, follicle interval shorter HBC group (HBC 6.2 ± 2.6 vs LBC 10.8 4.5 d; P < 0.05). corpus luteum intervals similar between but without expression. function both groups. did not affect
