Abstract


Birth weight is one of the growth characteristics in cattle which has an economic
value and correlated with slaughter weight. The study aimed to estimate breeding value of
candidate bulls in Kebumen Ongole Grade cattle based on birth weight. One thousands and
five (1005) heads of offsprings generated from 127 sires and 868 dams were used in this study.
Heritability was calculated using paternal half sib correlation method. Breeding Value (BV)
was calculated based on absolute dan relative value. The results showed that the heritability
(h 2 ) of birth weight was in high category (0.76 ± 0.12). Ten candidate bulls with the high
breeding values (35.92 – 34.99) were obtained. These results are expected to be an initial
recommendation in selecting candidate bulls in Kebumen based on BV.
