canal rediction, tissue composition and regional features in Pelibuey lambs supplemented with chicken manure. V. Estimation of kidney weight
Abstract
80 Pelibuey lambs supplemented with chicken manure and slaughtered at 34.3 were used; 30.0; 27.3 and 25.3 kg of live weight, to determine the equations for estimating kidney weight, through multiple regressions between regional traits and simple body measurements easily obtained in the live animal. The multivariate technique was used and the meat yield, size and length were selected as the main components that explained 82% of the total accumulated variance of the carcass yield. The thoracic perimeter, chest depth and cane perimeter zoom measurements were highly correlated with the weight and composition of the canal, so it was possible to obtain regression equations to estimate the weight of the kidney by combinations of them. nothing, with R2 = 81 ***, which can be very useful for producers, teachers and researchers, since this anatomical region is one of the most important and economic value in lambs. It is concluded that the estimation equation obtained is very useful, in productive practice, for the breeders of Pelibuey lambs.
