RESUMO  -   Este  estudo  teve  como  objetivo  avaliar  a  proporção  em  relação  ao  peso  de  corpo  vazio;  e  o  crescimento  alométrico  dos componentes não constituintes da carcaça de cordeiros da raça Texel terminados em confinamento e abatidos com diferentes pesos. Foram utilizados 30 cordeiros machos, não castrados e nascidos de parto simples. Os cordeiros foram desmamados com aproximadamente 50 dias de idade, confinados individualmente e distribuídos em cinco tratamentos com seis repetições, sendo cada tratamento um peso pré-estabelecido de abate (T23 – abate inicial, T25, T30, T35 e T40 kg de peso vivo).  As proporções de pulmão+traquéia, abomaso, intestino delgado, intestino grosso, cabeça e patas diminuíram e a proporção de testículos aumentou linearmente de acordo com o incremento no peso de abate dos cordeiros. Os componentes corporais fígado, diafragma, rúmen, retículo, omaso, pele, língua, testículos, gordura interna e gordura renal, apresentam desenvolvimento tardio. De forma inversa, pulmão+traqueia, esôfago, coração, pâncreas, rins, baço, abomaso, intestino delgado, intestino grosso, sangue, cabeça, patas e pênis, são componentes corporais que apresentam desenvolvimento precoce.

RESUMO  -   The objective of this study was to evaluate the proportion regarding the empty body weight, and the allometric growth of non-carcass components of Texel lambs finished in feedlot and slaughtered at different weights. It was used 30 male lambs, non-castrated and simple delivered. The lambs were weaned at 50 day-old,  individually confined and distributed in five treatments with six repetitions and each treatment with a predetermined slaughter weight (T23 – initial slaughter, T25, T30, T35 and T40 kg body weight). The proportions of  lung+trachea, abomasum, small intestine, large intestine, head and legs decreased and the proportion of testicles increased linearly according to the improvement on the slaughter weight of lambs. The body components as liver, diaphragm, rumen, reticulum, omasun, skin, tongue, testicles, internal fat and kidney fat present late development. On the other way, lung+trachea, esophagus, heart, pancreas, kidneys, spleen, abomasum, small intestine, large intestine, blood, head, feet and penis are body components that present early development.
