Selection for Bali Bull Based on Growth Traits Using Animal Model

Abstract

Bali cattle are one of the Indonesian germ plasma. The cattle have many advantages for development in the tropics. The purpose of the study was to selection for Bali cattle bulls based on animal models method. Data used comprised of 428 weaning weight, yearling weight and body weight gain derived from 28 males. Prediction of components of genetic and environment variance and co-variance, and heritability were obtained using VCE 4.2. Breeding value was estimated on the traits of production: weaning weight, yearling weight and body weight gain using PEST. The heritability of weaning weight, yearling weight and body weight gain was 0.09±0.15, 0.27±0.13, and 0.47±0.15, respectively.  The AI bull coded number 4 is the best male with relative breeding value of 33.227 kg.
