The present studyaimed to assess the effect of levels of supplementation with concentrate onthe tissue composition of commercial cuts of goats finished in native pasture.It was used 24 non-castrated cross-bred F1 (Boer × SPRD) goats at theage of 120 days, with initial average body weight (BW) of 15.52 kg distributedin four levels of supplementation with concentrated feed (0.0; 0.5; 1.0 and1.5% of body weight in dry matter) and slaughtered at 25.12 kg; 26.62 kg; 28.56kg and 29.19 kg, respectively, corresponding to 218 days of life. The carcasswas sectioned in the half, and from the left half of the carcass, the followingcuts were separated: leg, loin, ribs, shoulder and neck, which were dissectedinto muscle, bone and fat, with the results expressed in weight and yield ofthe tissues in relation to the weight of the cut. Supplementation increseadthe muscle weight, as well as the fat weight and yield and decreased the muscle:fatrelationship; however there was no influence on the proportion of muscle inthe five studied cuts. Therefore, in order to obtain better finished commercialmeat cuts, supplementation of 1.0 and 1.5% of body weight is recommended. Nevertheless,supplementation is unnecessary for obtaining lighter meat cuts with a good proportionof muscle.
