Abstract

Estimating heritability values can be used to implement selection programs and evaluate more targeted breeding programs in Bali cattle. This study aims to estimate the heritability value of birth weight, weaning weight and yearling weight of Bali cattle at Balai Pembibitan Ternak Unggul dan Hijauan Pakan Ternak (BPTU-HPT) Denpasar Bali. The research material used is the recording data of 500 Bali cows originating from 24 males  (sire)with 500 Bali cows (dam) that produce offspring of as many as 500 calves. The data was secondary data, obtained by taking records of body weight data, including birth weight, weaning weight, and yearling weight, along with pedigree data of Bali cattle raised from 2017 to 2021 at BPTU-HPT Denpasar. Estimating the heritability value is done using a one-way unbalanced layout model. The results showed that the heritability values of birth, weaning, and yearling weights were 0.25±0.09, 0.23±0.08, and 0.16±0.07, respectively. Based on these results, it can be concluded that the heritability value of birth weight, weaning weight and yearling weight in BPTU-HPT Denpasar Bali is included in the moderate category so that it can be used as a selection guide to increase the productivity of Bali cattle as local Indonesian cattle.

Abstract

This study aimed to evaluate the growth performance of Red-Combed Kedu (RCK), Black-Combed Kedu (BCK), and White Kedu (WK) chickens based on sex during the early growth phase (0 to 10 weeks of age). A total of 136 Kedu chickens were raised under uniform management conditions, consisting of 99 RCK (65 roosters and 34 hens), 29 BCK (5 roosters and 24 hens), and 8 WK (6 roosters and two hens). Body weight was recorded weekly and analysed using a two-way General Linear Model (GLM) in SAS to assess the effects of chicken variety, sex, and their interaction. The Shapiro–Wilk test confirmed that the data were normally distributed (p > 0.05). The results showed that sex had a significant effect on body weight from weeks 3 to 10 (p < 0.05), with roosters consistently exhibiting higher weights than hens. Significant differences among chicken varieties were observed only in the hen group at weeks 9 and 10, where BCK hens had higher body weights (p < 0.05) than WK hens, while RCK hens showed intermediate values. In contrast, no significant differences were found among rooster groups at any age. These findings suggest that genetic factors play an essential role in influencing growth performance in Kedu chickens, particularly in hens. This information provides a valuable foundation for breeding selection and the conservation of local chicken genetic resources.
