Relationship between body weight and body measurements of Aceh cattle

Putra W. P. B., . and Sumadi, . and Hartatik T., . and Saumar H., . Relationship between body weight and body measurements of Aceh cattle. pp. 35-43. ISSN 1394-3277

Data on body weight (BW) and measurements: withers height (WH) body length (BL) and heart girth (HG) of 79 (39 males and 40 females) of Aceh cattle (average 550 days of age) were collected at the Breeding Station in Indrapuri district Aceh Besar Indonesia to estimate the BW from body measurements. The data were subjected to standard statistical analysis using SPSS 16.0 software and linear regression analysis was applied by keeping BW as dependent variable and body measurements of WH BL and HG as the independent variables. The overall means ( SD) for BW WH BL and HG of Aceh cattle over the sexes were 129.37 30.84 kg 96.59 7.11 cm 93.10 11.77 cm and 118.15 11.08 cm respectively. Predicted BW based on C E F and G regression models showed no significant difference (P 0.05) with the means of actual BW. The study revealed that HG was the best predictor of BW estimate and this alone contributed more than 80 of the variation in the BW of Aceh cattle. It is concluded that a simple linear regression involving HG as the predictor variable has a high accuracy in predicting BW.

Abstract

Data on body weight (BW) and measurements: withers height (WH) body length (BL) and heart girth (HG) of 79 (39 males and 40 females) of Aceh cattle (average 550 days of age) were collected at the Breeding Station in Indrapuri district Aceh Besar Indonesia to estimate the BW from body measurements. The data were subjected to standard statistical analysis using SPSS 16.0 software and linear regression analysis was applied by keeping BW as dependent variable and body measurements of WH BL and HG as the independent variables. The overall means ( SD) for BW WH BL and HG of Aceh cattle over the sexes were 129.37 30.84 kg 96.59 7.11 cm 93.10 11.77 cm and 118.15 11.08 cm respectively. Predicted BW based on C E F and G regression models showed no significant difference (P 0.05) with the means of actual BW. The study revealed that HG was the best predictor of BW estimate and this alone contributed more than 80 of the variation in the BW of Aceh cattle. It is concluded that a simple linear regression involving HG as the predictor variable has a high accuracy in predicting BW.
