AshmawiG.M. 72015107Five body measurements of 45 ram-lambs from Barki, Ossimi and Rahmani fat-tailed breeds (15 of each) were recorded at slaughter at 12 months of age to predict weights of live body and hot carcass. The measurements were body length, height at withers, heart girth, paunch girth and leg circumference. Simple correlation coefficients between body measurements with body weight and carcass traits were calculated. The stepwise procedure was used to select the variable for prediction equations of carcass composition. In Ossimi and Rahmani ram-lambs, body weight was significantly correlated with most measurements, while in Barki ram-lambs only heart girth was significantly correlated with body weight. All body measurements used to predict the weights of body and hot carcass had positive and significant regression coefficients. To predict total trimmed meat weight of Ossimi and Rahmani, heart girth must be included in the models with an accuracy of 0.66 and 0.89. The obtained results clearly indicate that weights of live body, hot carcass, total trimmed meat and total bone in carcasses could be predicted by measuring some live body measurements such as body length, heart girth, height at withers, leg circumference and paunch girth in ram-lambs of the three Egyptian breeds. Moreover, body length, withers height and leg circumference represented good body measurements to predict leg weight of the three Egyptian breeds (R2 = 0.70).]]>Abdel-Mageed, I. and N.
