    This study aimed at assessing the physicochemical and microbiological quality of feedlot-finished,聽culled Santa In锚s ewes and Moxot贸 goats, and compares the intake, weight gain and carcass聽characteristics. Three Santa In锚s ewes and Moxot贸 goats with similar ages were confined in double聽and/or individual pens and then euthanized after 40 days of confinement. The average intake, daily聽weight gain, hot carcass yield, cold carcass yield, weight loss by cooling and rib eye area (94.45%,聽0.220 kg/day, 41.37%, 40.14%, 2.99%, 16.1 cm虏, respectively) of the Santa In锚s ewes were higher than聽that of the Moxot贸 goats (84.01%; 0.06 kg/day; 41.55%; 39.81%; 4.12%; and 11.35 cm虏, respectively). The聽chevon (goat meat) showed higher protein levels (23.09 g/100 g), lower lipid levels (1.43 g/100 g) and聽higher red-color intensity (11.62), although it had lower tenderness (8.98 kgf shear strength). The聽superiority of the culled ewes was assessed relative to that of the culled goats, and the results showed聽that the Santa In锚s sheep has better performance than the Moxot贸 goats. However, mutton and chevon聽derived from the culled animals are promising alternatives for small farmers because culled meats add聽value to the standard meat obtained from these animals, broaden sales alternatives and increase聽profitability.Key words: Performance parameters, physicochemical parameters, microbiological parameters, cull animals
