Popis: The aim of this study was to evaluate the modulation of skeletal muscle fibres from Ile de France lambs fed with levels of whole cottonseed (WCS), as well as to develop sheep meat products and characterise them. This study was composed of three experimental tests. The first evaluated the serum levels, modulation, and performance of skeletal muscle fibres of Longissimus thoracis of Ile de France lambs fed with whole cottonseed and its relation to meat quality. The skeletal muscle fibres were identified by histochemical analysis and classified according to contraction velocity, staining and metabolism. Fifty Ile de France lambs, five references and five treatments (0, 10, 20, 30 and 40% WCS in the diet) were used, with nine replicates and a completely randomised design. The linear and quadratic trends, as well as the Spearman partial correlation between fibre characteristics and meat quality (58 variables) were evaluated, with whole cottonseed levels being used as covariates. Serum cholesterol, total protein and gamma glutamyl transpeptidase levels increased (P0.05) the texture profile, but they negatively affected the acceptability of the hamburgers (P0,05) o perfil de textura, mas afetaram negativamente a aceitabilidade dos hambúrgueres (P
