PREDICTION OF LIVE BODY WEIGHT AND CARCASS TRAITS BY SOME LIVE BODY MEASUREMENTS IN BARKI LAMBS

The relationship among certain live body measurements (body length BL, heart girth HG and height at withers HW) and each of live body weight (LBW) and carcass traits were studied on 139 Barki lambs which slaughtered at 12 months of age. The study showed significant correlation coefficients between LBW, carcass traits and each of BL, HW and HG. Both BL and HG were responsible for 74 and 82% of the variation of LBW and 79 and 72 % of the variation in hot and chilled carcass weight, respectively. The measure of HG was an effective predictor and accounted for 67 %, 45 %, 61% and 61% of the variation in leg, loin, rack and shoulder cut weights, respectively. In conclusion, certain live body measurements can effectively predict the weights of live body, hot carcass, chilled carcass and prime cuts of Barki lambs.
