Resumo:  The objective of the present study was to assess the growth performance and carcass traits of Moxotó goat kids fed different levels concentrate (supplement) (SL) on native pasture under semiarid conditions in Brazil. Thirty-two castrated kids (15.7±0.78 kg initial BW) were allocated randomly to one of the four SL (treatment groups: 0, 5, 10 and 15 g/kg BW). When the animals of treatment group 15 g/kg BW reached 25 kg BW, the animals in the other treatments groups were also slaughtered. Therefore, the animals belonging to the 0, 5, 10 and 15 g/kg of BW were finished with 18.40, 21.04, 22.94 and 25.74 kg of BW, respectively. The concentrate supplementation positively influenced the performance and the carcass traits of animals, providing higher feed intake and thus greater weight gain. The results of cold carcass yields were 405.9, 427.0, 449.1 and 462.9 g/kg of SBW for 0, 5, 10 and 15 g/kg BW, respectively. The weight of the different commercial cuts, (neck, ribs, shoulder, loin and leg) increased linearly as the SL increased; however the yields of the carcass cuts were not influenced, except for the shoulder. Overall, the distribution of non-carcass fat increased as SL increased, with the exception of mesenteric fat yield, which was not influenced. The use of concentrate supplementation to Moxotó goats under grazing conditions on native rangelands of the Brazilian semiarid improves the performance of animals and carcass yield, but does not affect the yields of commercial cuts of Moxotó growing goats.
