%X The aim of the research was to evaluate the genetic improving of production traits selected of Bali cattle. Four hundred and twenty eight data of weaning weight, yearling weight and body weight gain were used to estimate genetic improvement for those traits. One hundred and seven data of body dimension (body weight, chest circumference, body length and withers height) at 24 months old were used to estimate genetic improving for those traits. The estimation of genetic and environmental variance and co-variance component, and heritability were found by animal model. The fix effect of weaning weight, yearling weight and body weight gain was rainfall, age of measurement and year of birth, whereas the fix effect of body dimension depend on each trait. The result showed that heritability of weaning weight, yearling weight, body weight gain, body weight, chest circumference, body length and withers height was 0.09 0.15, 0.27 0.13, 0.47 0.15, 0.07 0.19, 0.50 0.19, 0.34 0.28, 0.60 0.21, respectively. Genetic improvement of all traits have had a different pattern in selection responses. All traits did not show genetic improvement due to selection.
