Estimation of live weight of Holstein-Friesian bulls by using body linear measurements

Abstract

The objective of this study was to estimate the body weight of Holstein-Friesian cattle by using multiple regression analysis. Data were collected from 29 Holstein-Friesian bulls, whose live weight, body length (BL), height at withers, chest depth, heart girth (HG), shin circumference (SC), rump height, and back rump height were measured. There was a relationship between dependent and independent variables. The estimated multiple regression equation was -431.8 + 2.438 HG + 21.21 SC + 1.041 BL, with a determination coefficient of 0.9987 and a standard error of the estimate of 5.240.
