Area specific mineral mixture, Buffalo, Reproductive performanceAbstract
In a field trial the efficacy of area specific mineral mixture (ASMM) supplementation on reproductive efficiency in buffaloes was assessed. Out of the 280 buffaloes examined, 220 had postpartum anestrus (40%) and repeat breeding (20%) followed by delayed sexual maturity (20%), silent heat (10.9%) and endometritis of mild to moderate degree (9.09%). Among the postpartum anestrus buffaloes 52.27% and 45.65% exhibited estrus and conceived, respectively, within 3 months of ASMM supplementation. Among the repeat breeders, which received the ASMM, 38.63% conceived within 3 inseminations. Onset of estrus occurred in 50% of the delayed pubertal animals, which received the ASMM. However, from silent estrus cases, 37.5% conceived within 3 months of the ASMM supplementation. The present study indicated that supplementation of ASMM improves reproductive performance in buffaloes under rural conditions.
