ABSTRACT - The aim of this study was to evaluate the effect of different levels of cottonseed (0, 100, 200, 300
and 400 g Kg-1) on the physical and chemical parameters of the meat of finishing lambs. Forty-five uncastrated male
lambs were distributed in a completely randomised design with five treatments of nine replications. The pH values
were not influenced by the levels of cottonseed. The lipid and ash content showed significant differences, but were
not adjusted by the linear or quadratic equations. Losses during thawing increased, as did cohesiveness, and water
activity and water retention capacity decreased as the levels of cottonseed in the diet rose. Tocopherols, cooking loss,
toughness and chewiness were adjusted using quadratic equations. In the instrumental colour evaluation, L*, b* and h°
showed increasing linear behaviour. The inclusion of up to 400 g of cottonseed in the diet affects the physical-chemical
composition and the colour of the produced meat.

RESUMO - Objetivou-se avaliar o efeito dos níveis de caroço de algodão (0; 100; 200; 300 e 400 g Kg-1) na terminação
de cordeiros sobre os parâmetros físicos e químicos da carne. Utilizou-se 45 cordeiros, machos, não castrados, distribuídos
ao acaso em delineamento inteiramente casualizado com cinco tratamentos e nove repetições cada. Os valores de pH, não
foram influenciados pelos níveis de caroço de algodão. Os teores de lipídios e cinzas apresentaram diferença significativa,
mas não foram ajustados pelas equações lineares ou quadráticas. As variáveis perdas por descongelamento e coesividade
aumentaram, e a atividade de água e capacidade de retenção de água diminuíram com o incremento de caroço de algodão
na dieta. Já os tocoferóis, perdas por cocção, dureza e mastigabilidade foram ajustados através de equações quadráticas. Na
avaliação instrumental de cor o L*, b* e h° demonstraram comportamento linear crescente. Logo a inclusão de até 400 g de
caroço de algodão na dieta influencia a composição físico-química e na cor da carne produzida.
