摘要
O objetivo foi estudar a introdu o de 8% de gr os e subprodutos (farelo ou torta) da canola em dietas para cordeiros. Para a avalia o das caracter赤sticas quantitativas da carca a, foram utilizadas 24 carca as de cordeiros, utilizando delineamento inteiramente casualizado. As dietas com m谷dia de 15,4% de PB na MS e 80,2% de NDT foram compostas por 40% de feno de capim-Tifton e 60% de concentrado composto por milho em gr o, farelo de soja, canola em gr o integral, farelo de canola, torta de canola e mistura mineral. A utiliza o de gr os e subprodutos da canola na dieta de borregos terminados em confinamento n o influenciou (p %26gt; 0,05) as caracter赤sticas quantitativas da carca a. Em rela o aos rendimentos dos cortes, n o houve efeito dos tratamentos para nenhuma das vari芍veis analisadas. Assim, a introdu o de 8% de gr os e subprodutos (farelo ou torta) da canola possibilitaram bons resultados podendo ser recomendados nas formula es de dietas para cordeiros. The aim of this work was to evaluate the introduction of 8% grains and by-products (meal or cake) of canola in the diets of lambs. To evaluate quantitative carcass characteristics, 24 Santa Ines lambs were used in a completely randomized design. Diets with averages of 15.4% of CP in DM and 80.2% of TDN were composed for 40% Tifton hay and 60% concentrate based on corn grain, soybean meal, whole grain canola, canola meal, canola cake and mineral mixture. The use of whole grains and by-products of canola in the diet of lambs finished in feedlot did not influence (p %26gt; 0.05) quantitative carcass characteristics. For cut dressing in relation to the CCW, no effect was observed for the analyzed variables among treatments. It was concluded that the introduction of grains and by-products of canola allow for satisfactory results, and could be recommended in the formulations of lamb diets.
