Características de Carcaça de Cordeiros Texel x Bergamácia, Texel x Santa Inês e Santa Inês Puros, Terminados em Confinamento, com Casca de Café como Parte da Dieta

Abstract

Thirty six Iambs (18 male and 18 female) from three different genetic groups: 12 lambs Texel x Bergamacia, (T B), 12 lambs Texel x Santa Inês (T S) and 12 lambs pure Santa Inês (SI) were fed with three different experimental diets: A - without coffee hulls; B - with in natura coffee hull and; C - with coffee hull, treated with urea and whole ground soybean seed. The hot carcass weight (CQ), cold carcass weight (CF), hot carcass dressing (RC), cooling weight loss (QR) and the measures of internal length (CI), and total (CE), leg length (CP), total leg length (CTP), croup circumference (PG), croup width (LG), thoracic depth (PT) and subcutaneous fat width (GS), according to the diet, the genetic group and sex were evaluated. Diets did not affect any of the analyzed variables. The crossbred T x B and T x S lambs showed lower CTP and higher PG, LG, and GS. The Tx B lambs showed higher values for PT. There were higher hot and cold carcass wei ghts for the crossbred lambs, and there was no difference for hot carcass dressing among the genetic groups. There was no difference between male and female lambs for GS. The female lambs showed better RC than male lambs. The male lambs showed higher values for all the other characteristics in relation to the female lambs.
