ESTIMATED BREEDING VALUE OF PRE-WEANING GROWTH TRAITS IN THE SIMMENTAL CATTLE OF INDONESIAWIDYA PINTAKA BAYU PUTRA, SYAHRUDDIN SAID AND IRWANDI
Simmental cattle (Bos taurus) is one of the beef cattle breed that has high value of meat production. This research was carried out to calculate Estimated Breeding Value (EBV) of pre-weaning growth traits in Simmental cattle at the breeding station. The records data of birth and weaning weights from year 2012 to 2017 were used in this study. Research showed that the average of corrected birth weight (BWC), weaning weight at 205 days of age (WW205) and average daily gain (ADG) in animals study were 42.82Â±6.24 kg; 193.69Â±40.45 kg and 0.74Â±0.19 kg/day respectively. Hence, the heritability (h2) value of BWC; WW205 and ADG were 0.84Â±0.33; 0.81Â±0.32 and 0.70Â±0.30 respectively. The highest of cumulative estimated breeding value for sire (EBVSire) was +61.31kg (Bull ID: W. Drovin). Meanwhile, the highest of cumulative estimated breeding value for progeny (EBVProg) in male calf was +86.86 kg (Calf ID: 000354) and in female calf was +79.01 kg (Calf ID: 000435). It was concluded that BW, WW and ADG traits had highly of h2 value (h2>0.30) and indicating that both traits can be increased through selection program.
