English Abstract

The objectives of this research were to analyze the body performance in various groups of age and to estimate the correlation between body size and body weight in Ongole Grade cattle. This research was conducted in two sub-districts (Kedopok and Wonoasih) of Probolinggo City started from 21st February to 21st March 2020. Materials used were 70 heads of Ongole Grade cattle consisted of 6–12, 18–24, and 25–36 months old. Variables observed were wither height (WH), body length (BL), chest girth (CG), and body weight (BW) at 6–12, 18–24, and 25–36 months old. Data were analyzed by using unpaired t-test, coefficient of correlation, coefficient of determination, and simple linear regression. The results of unpaired t-test showed that means of body performance between male and female was significantly different (P<0.05) on wither height at 6–12 months old (110.80±10.73 cm and 101.87±7.31 cm, respectively). The phenotypic correlations between chest girth and body weight at 6–12, 18–24, and 25– 36 months old showed the positive highest result in each group of age with the values of 0.87, 0.95, and 0.85, respectively, and the results for coefficients of determinations were 75.71 %, 89.46%, and 72.38%, respectively. The simple linear regression equations for estimated body weight (Y) based on chest girth (X) in Ongole Grade cattle at 6 – 12, 18 – 24, and 25 – 36 months old were: Y= – 159.24 + 2.51X, Y= – 462.97 + 4.92X, and Y= – 358.77 + 4.22X, respectively. It indicated that chest girth could be considered as the best estimator to estimate body weight in Ongole Grade cattle.
