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 422 weaning weight, yearling weight and body weight gain derived from 22 males. Prediction of components of genetic and environment variance and co5variance, and heritability were obtained using VC8 4.2. Breeding value was estimated on the traits of production: weaning weight, yearling weight and body weight gain using P8ST. The heritability of weaning weight, yearling weight and body weight gain was 0.09±0.11, 0.27±0.13, and 0.47±0.11, respectively. The AI bull coded number 4 is the best male with relative breeding value of 33.227 kg.
