This paper aimed to provide a reliable method to predict Bali cattle’s body weight (BW). In total 1051 records were obtained which comprised of BW, Chest Girth (CG), Body length (BL) and Whither Height (WH) data from three age groups (weaning, yearling and mature). Data were analyzed separately for each sex and age groups. The predicted BW data were derived from two linear models and conversion from cattle weight measure tape. The model with CG, BL and WH as predictor has better model fits than the model with only CG. Both models have reliable prediction ability indicated by low RMSE (6.623 - 18.684) and CV-RMSE values of less than 25%. Utilizing measuring tape as prediction tool is not recommended due to its poor performance (CV-RMSE > 25%). Bali cattle is a distinct cattle species with unique characteristics; hence, linear model is a suitable method to predict the BW for further purposes. [ABSTRACT FROM AUTHOR] |
