Linear Regression Equations for Estimation of Body Weights in Sahiwal Calves


DOI:Coming soon...

Abstract:

The study was conducted on 194 purebred Sahiwal calves of both the sexes and different age groups (0-6, 6-12, 12-18, 18- 24 and 24-36 months) to find out the correlation coefficients between body weights and different body measurements and to develop linear regression equations for prediction of body weights of the various age groups. Among the body measurements, heart girth shown highly significant and highest correlation coefficients with body weights. It was concluded that the linear regression equations incorporating heart girth alone could be used to predict body weights of growing Sahiwal cattle.
