Effect of Bone Meal Supplement on Reproduction of Melengestrol Acetate-Synchronized Native Cattle


Author(s): S. C. Bantugan and J. R. Escano

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.
