Resumo: Sixty three steers from zebu breeds Gyr, Guzerat, Mocho Tabapua and Nellore, weighing, respectively, 376.4, 357.6, 362.0 and 368.6 kg initial live weight and twenty-four months old, were used. The animals from each breed were divided into five groups. One group was ramdomly assigned to immediate slaughter (AB), three groups were full-fed a ration containing 50% concentrate, dry matter basis until reaching the slaughter weights of 405, 450 and 495 kg, respectively (group I, II and III). The fifth group was fed a restricted amount of the same ration (AR). At slaughter the empty body weight (EBW) was determined and the weight of internal organs and viscera were recorded. Regression equations of log weight of body component as a function of log EBW were fitted. All body components studied, with exception of liver and spleen, developed slowlier than EBW.

Os animais de cada raça foram divididos em cinco categorias. Uma categoria foi abatida imediatamente (AB), três receberam, em baias individuais, ração contendo 50% de concentrado na matéria seca ad libitum (I, II e III) e uma recebeu a mesma ração, em quantidade restrita (AR). Os animais I, II e III foram abatidos ao atingirem pesos vivos individuais de 405, 450 e 495 kg, respectivamente. No abate determinou-se o peso corporal vazio (PCVZ), e pesaram-se a cabeça, os pés, o couro, os órgãos internos e as vísceras. Adotou-se a equação de regressão do logaritmo do peso de cada componente do corpo em função do logaritmo do PCVZ. Todos os componentes estudados, excetuando-se o fígado e o baço, revelaram um menor ímpeto de crescimento em relação ao do PCVZ.Editora da Universidade Estadual de Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/320210.4025/actascianimsci.v22i0.3202Acta Scientiarum.
