Abstract

The study is aimed to estimate the heritability for growth traits at weaning and yearling age, and to determine the breeding values for body weight in Madura cattle, reared in Pamekasan Regency. One hundred and four (194) calves were collected for body weight (BW), chest circumference (CC), body length (BL), withers height (WH) at weaning and yearling age. Paternal half-sib correlation method was used for heritability estimates. As a result, the estimates of heritability for growth traits in both weaning and yearling age were categorized in medium to high. The heritability estimates for BW, CC, BL, and WH in weaning age were 0.33±0.30, 0.35±0.31, 0.66±0.37 and 0.53±0.34, respectively. In yearling age, heritability estimates for BW, CC, BL, and WH were obtained to be 0.66±0.43, 0.71±0.67, 0.38±0.58, and 0.36±0.57, respectively. The top 10 sires based on estimated breeding value for body weight were also obtained, with a range value from 80.70 to 88.35 in weaning age, and from 101.86 to 118.55 in yearling age. It was found that the analyzed growth traits may be taken into consideration as selection criteria in Madura cattle.
