Abstract

This research aimed to estimate genetic parameters (heritability, genetic correlation) and breeding value and used these parameters to estimate selection responses and correlated response to selection of birth and weaning weight of male Saburai goats. Data of birth and weaning weight of ninety male Saburai kids (2017-2018) generated from nine bucks and 45 does were used in this study. Heritability, genetic and phenotypic correlation were estimated using paternal half-sib data. The results showed that heritability estimates for birth and weaning weight were moderate category (0.30±0.08 and 0.22±0.07, respectively). Genetic correlation between birth and weaning weight was categorized as a high positive value (0.42±0.06), while phenotype correlations between the two traits were 0.10 (low), and environmental correlations were 0.56 (high). Responses to selection increased with increasing selection intensity ranging from 0.11 kg to 0.28 kg and 0.60 kg to 1.54 kg for birth and weaning weight, respectively, at 50% to 5% selection proportion. The response of the selection of correlated traits expected to direct birth weight selection impacted on weaning weight ranged from 0.29 kg to 0.75 kg at a selection proportion of 50% to 5%. The moderate heritability and positive genetic correlation between birth and weaning weight suggested that selection for any of these two traits should be successful and improving birth weight will improve the weaning weight of male Saburai goats as well. However, indirect selection (birth weight selection) will impact on the lower response for weaning weight compared to direct selection for weaning weight.
