ABSTRACT
This study aimed to analyze the correlation between body weight and body measurements at 205 and 365 days of age in Bali cattle. The total samples used in this study were 437 Bali cattle consisting of 248 males and 189 females. The traits measured were hip height (HH), body length (BL), and chest girth (CG) at 205 days. The data were collected from 2018 to 2020 in the Breeding Centre of Bali cattle. The regression and correlation between body weight and body measurement were analyzed using SPSS version 26.0. The result showed that positive correlations were observed between BW and all body measurements. The highest positive correlation was found between BW and three variates (HH, BL, and CG), whereas the lowest correlation occurred between BW and HH. The reverse pattern was observed in the standard error of the mean (SEM). The traits with the highest correlation had the lowest SEM. In this study, the linear regression models for 205 were Y = −159.173 + 0.355 HH + 0.715 BL + 1.430 CG. This study concluded the BW at 205 days of age could be estimated from three variates (HH, BL, and CG) as the best linear regression models. For instance, the BW estimation accurately and easily based on CG could be done by everyone to accelerate and support the selection program of Bali cattle.
