It was evaluated the effect of supplementation feeding levels (0; 0.4; 0.8; and 1.2% of body weight BW) on carcass aspects and leg tissue composition of crossbred goats finish on caatinga pasture. Were used 32 goats crossbred Anglonubiana, with eight months of age and 18±2.5 kilogram of BW, organized in randomized blocks, which were kept in 37 hectares of caatinga pasture, where they remained from 07h to 16h. Fasted live weigh, finish body weight, hot and cold carcass weight, empty body weight, hot and cold carcass yields, were influenced (P<.05) by supplementation feeding, raise of 3.50; 2.59; 1.69; 1.76; 3.39 kilogram, and 2.43; 2.44%, respectively. Retail cuts weight were influenced (P<.05) by supplementation, except neck weight. The cuts yield was not affected (P>.05) by supplementation with means, 10.17; 21.19; 16.23; 11.02; 7.30 and 34.08%, for neck, shoulder, ribs, brisket, loin and leg, respectively. Absolute weight of leg tissue composition was influenced (P<.05) by supplementation, with increase of, 293.59, 212.04, 28.29 and 53.82g, per unit percentage of supplementation, for total leg, total muscle, total fat and bone, respectively. Supplementation feeding increase carcass aspects, associated with increases in leg muscle tissue, fat and bones, recommending use of 1.2% of BW, to better finish for sale.
