Repeatability Estimates for Birth, Weaning and Yearling Weight in Madura Cattle

This study was aimed to estimate the repeatability value for body weight. Data on body weights of 186 offsprings of Madura cattle were taken at birth, weaning and yearling. All animals were reared under similar production system by breeders in Pamekasan regency, Madura. The repeatability values were estimated by HGLM- REML (Hierarchical Generalized Linear Model-Restricted Maximum Likelihood) using Genstat software. The result showed high repeatability value for birth weight (0.46±0.15), weaning weight (0.38±0.11) and yearling weight (0.33±0.07). The high estimates indicated that selection on the basis of first record will be effective to improve body weight at birth, weaning and yearling.
