Abstract

Bone meal supplement slightly improved the reproductive performance of melengestrol acetate (MGA)-synchronized native cattle. Synchronized estrus was higher among cows (80%) and among heifers (90%) in the bone meal supplemented group compared to 80% among cows and 60% among heifers in the control group. The overall breeding effects showed that bone meal supplement had no effect on conception rate among heifers wherein 66.7% conception was recorded on both treatments with 1.7 and 2.0 services per conception in the bone meal supplemented and control group, respectively. Cows showed 62.5% conception with 1.8 services per conception in the bone meal supplemented group compared to 37.5% conception with 2.0 services per conception in the control. No significant differences were observed in all the reproductive parameters investigated.
