The aim of this study was obtained the best linear regression equation for body weight (BW) through body measurements in 58 heads of Sumba Ongole (SO) cattle raised at the breeding centre (PT. Karya Anugerah Rumpin). Total of 17 heads males and 41 heads females were used in this study. Three body measuremens of withers height (WH), body length (BL) and heart girth (HG) were in this study. The average of ages, BW, WH, BL and HG in SO cattle were 588.47±186.78 hari, 247.86±96.94 kg; 116.86±17.14 cm, 121.34±15.63 cm and 150.38±26.08 cm respectively. The highest coefficient of determinaton value (R2=0.89) was reached in linear regression using HG variable. Three body measurements in this study were non-collinearity and reveals that the linear regression in this study were accurate. The T-test analysis was showed that effect of sex to the cattle performance was not significant and reveals that the linear regression in this study can be performed in SO population. It was concluded that linear regression equation of BW = 3.50 (HG) - 278,53 can be used as the predictor formula for SO cattle at about 588 days of age.
