This study aimed to evaluate the weights and carcass and commercial cuts of native goats and sheep fed with hay or Tifton 85 (Cynodon dactylon) orManiçoba hay (Manihot pseudoglaziovii) associated with the spineless cactus (Nopalea cochenillifera). We used 32 animals (16 Morada Nova lambs and 16 Moxotó breed goat) in a randomized block design and a 2x2 factorial design (species x hay). The animals fed Tifton 85 hay had higher hot carcass weight (11.58 kg) and higher cooling loss (6.35%). There were no differences among the hay, to slaughter weight, hot carcass, cold carcass weight, cold carcass, empty body weight and biological yield. The yields of cuts (%) were not affected by the substitution of Tifton 85 hay by Maniçoba hay, except for the internal length and girth of the chest, the measures of carcass werenot affected. Morada Nova lambs were heavier and carcass and meat cuts that Moxotó breed goats fed the same diet.
