Effect of supplementation of area specific mineral mixture in improving reproductive efficiency in crossbred dairy cattle–a field study

Abstract

The efficacy of a supplemental mineral mixture (area specific mineral mixture, ASMM) on improving reproductive efficiency in crossbred dairy cattle was assessed in this study. Out of the 110 crossbred dairy cattle examined, 73 were had reproductive problems such as postpartum anestrus and repeat breeding (28% each), followed by delayed puberty (21%), silent heat (10%), infectious endometritis of mild to moderate degree (10%) and cystic ovary (3%). Among the postpartum anestrus animals, 84.21 and 85.71% exhibited estrus and conceived, respectively, within 2 months of ASMM supplementation. Among the repeat breeders, which received the ASMM, 78.6% conceived within 2 inseminations. Onset of estrus occurred in 66.7% of the delayed pubertal animals, which received the ASMM supplementation. Among the silent heat animals, 66.7% conceived within 3 months of the ASMM supplementation. The present study indicated that supplementation of the ASMM improved reproductive performance in crossbred dairy cattle.
