Conteúdo: 	Carcass data werc used to develop equations for predicting weights of several cut-out yields for bulls from two experments conducted at the Instituto de Zootecnia in São Paulo, Brazil. These data of 72 young bulls were obtained from 32 Nellore. 18 112 blood Marchigiana-Nellore, 12 1/2 blood Chianina-Nellore and 10 1/4 blood Marchigiana-Nellorc. Equation 1, used to predict weight of trirrimed total carcass cuts (Y = -6.8074 + 0.8021 (chified carcass weight in kilograrns - 3.1021 (kidney and pelvie fat percentage) + 0.2743 (fat tliickness in millimiters)), would seem to be the most uscful, since it utilizes threc casily obtainable variables and is highly accuratc (R 2 = 0.96). Chilled carcass weight was the independent variable with lhe greatest contribution in all prediction equations. AU the models included chiNed carcass weight and kidney and pelvic fat percentage as independent variables.
