Resumo: | The effect of the substitution of Tifton hay (0, 33, 66, 100 g/100 g) for pineapple (Ananas comosus L.) stubble hay was evaluated in the characteristics of the carcasses of goats of an unknown breed (UB) in feedlot. Thirty-two bucks with an average initial live weight of 17.5±1.3 kg, at approximately 150 days of age, were housed in individual stalls provided with feeding and drinking troughs. The animals were distributed in a completely randomized design with four treatments and eight replications. There was a quadratic effect on the weights of hot carcass and cold carcass, empty body, and loin eye area. A linear increase was observed for losses by carcass cooling. The weights of commercial cuts and the weights of total muscle, total bone, intramuscular fat, and total fat decreased linearly. All morphometric measurements were influenced by the inclusion of pineapple stubble hay in the .diets. Substitution of Tifton hay for pineapple stubble hay at the level of 33 g/100 g improves the carcasses of UB goats qualitatively and quantitatively
