Breeding value of sires based on offspring weaning weight as a recommendation for selecting Kebumen Ongole Grade cattle
Abstract: The objective of
study was to estimate breeding value of sires of Kebumen Ongole grade cattle
based on offsprings weaning weight. This research was carried out from August
to December 2015 in Urut Sewu area, Kebumen. The calculation of genetic
parameter estimation was heritability of weaning weight. The value of
heritability was used to calculate the breeding value of sires based on
offsprings weaning weight. Heritability was calculated using paternal half-sib
correlation with the direct pattern variance analysis. Breeding Value (BV) of
sire was calculated by absolute estimated breeding value. The materials used in
this study included were data record during the last three years (2013-2015)
consisted of 41 sires, 51 dams and 244 calves. Weaning weight data had been
corrected based on age of dams, sex and weaning age of 120 days. The results
showed that the heritability value of weaning weight was included in high
category (0.36 ± 0.21). The highest BV was KJ.J608 (49.76) with a ratio of
231.45%. The results of this study were expected to be the basis recommendation
for selecting sires in Kebumen.
