The objective of this work was to evaluate the "buchada" - composed of heart, lungs, liver, spleen, intestines, stomach and blood - yields, the weights and yields of organs, visceras, and carcass of undefined breed Caatinga grazing-fed goats, with or without supplementation. Eighteen castrated male goats with initial live weight of 15±0,55 kg, were kept in a grazing area in the Caatinga vegetation, Pernambuco state, Brazil, during 105 days. Animals were subjected to three treatments in a completely randomized design: grazing at will, without supplementation; restricted grazing; and grazing at will, with supplementation of soybean meal and forage cactus. Supplemented animals had higher weight at slaughter (PVA), higher empty body weight (PCVZ), and higher weight of tongue, lungs + trachea, heart, spleen, diaphragm, pancreas and kidneys. The weights of liver, gallbladder and reproductive tract showed no difference between treatments. The absolute value of "buchada" weights was influenced by treatments, and supplemented animals had the higher ones. "Buchada" yields in terms of PVA and PCVZ did not differ between treatments. The supplementation for grazing-goats raised in Caatinga produces animals with higher PVA, PCVZ and "buchada" weights, but does not influence the "buchada" yields, in terms of PVA and PCVZ.
