Estimation of live weight from chest girth in pure and crossbred West African sheep. (380)

K. Benyi, N. Karbo

Abstract


Live weight and chest girth data on 144 Djallonke and 168 Sahel x Djallonké sheep were used to obtain linear and geometric regression equations for estimating live weight. The coefficients of determination ranged from 0.88-0.93 and 0.96-0.97 for linear and geometric equations, respectively. The geometric equations estimated live weight with a high degree of reliability regardless of girth size, while the linear equations gave very low and frequently negative live weight estimates where girth measurement were below 36 cm.
