Abstract
The present investigation was carried out on 459 Murrah buffaloes affected with some reproductive problem with 618 calving records(out of total 1336 Murrah buffaloes) sired by 118 sires over a period of 12 years from 2007 to 2018 at GADVASU, Ludhiana. The heritability estimates for dystocia, retention of placenta (ROP), anestrus, repeat breeding (RB), abortion and postpartum abnormal discharge (PPAD) were 0.04, 0.10, 0.05, 0.074, 0.085 and 0.121 respectively. The overall means for breeding values for dystocia, ROP, abortion, anestrus, RB and PPAD were 0.4, 0.2, 0.4, 0.2, 0.078 and 11.8%, respectively. Rank correlation of abortion with ROP was very high (0.99±0.02) and with anestrus, dystocia, RB and PPAD were also high i.e. 0.98±0.03, 0.98±0.03, 0.97±0.03, 0.95±0.04 respectively. Heritability estimates of reproductive problems have indicated appreciable values, signifying that incorporation of these traits in selection program will enhance the rate of improvement.
