GENETIC IMPROVEMENT OF WEANING WEIGHT, YEARLING WEIGHT, BODY WEIGHT GAIN AND BODY DIMENSION OF BALI CATTLE
Abstract: The aim of the
research was to evaluate the genetic improving of production traits selected of
Balicattle. Four hundred and twenty eight data of weaning weight, yearling
weight and body weight gainwere used to estimate genetic improvement for those
traits. One hundred and seven data of bodydimension (body weight, chest
circumference, body length and withers height) at 24 months old wereused to
estimate genetic improving for those traits. The estimation of genetic and
environmentalvariance and co-variance component, and heritability were found by
animal model. The fix effect ofweaning weight, yearling weight and body weight
gain was rainfall, age of measurement and year ofbirth, whereas the fix effect
of body dimension depend on each trait. The result showed that heritabilityof
weaning weight, yearling weight, body weight gain, body weight, chest
circumference, body lengthand withers height was 0.090.15, 0.270.13,
0.470.15, 0.070.19, 0.500.19, 0.340.28, 0.600.21,respectively. Genetic
improvement of all traits have had a different pattern in selection responses.
Alltraits did not show genetic improvement due to selection for.
