Resumo: | The objective of this study was to evaluate the effect of the replacement of a ground corn diet by a forage cactus meal diet on the carcass characteristics and body components of Santa Inês lambs finished in feedlot. This study was carried out at Estação Experimental de Pendência, belonging to Empresa de Pesquisa Agropecuária da Paraíba S.A. (EMEPA-PB). Forty Santa Inês male lambs in feedlot were used in the experiment. Treatments were randomly assigned to the animals according to a completely randomized design, with four treatments, which consisted of growing replacement levels of ground corn by forage cactus meal: 0, 33, 66 and 100% of substitution and ten replications (lambs). Animals were slaughtered, and the following characteristics were evaluated: body weight, empty body weight, hot carcass weight, cold carcass weight, non-carcass components (NCC), hot carcass yield, cold carcass yield, biological yield, revenue of non components of carcass, revenues of non-carcass components, relative weight and relative value of the commercial cuts, viscera and organs' yield. Averages were submitted to analysis of variance and regression analyses at a 5% level of probability. The replacement levels of ground corn by forage cactus meal had no influence on biological yield, revenue of the non components of carcass, relative weight and relative value of the prime and choice cuts or on the relative weight of viscera and organs. The replacement of ground corn by forage cactus meal, on the ration given to Santa Ines lambs in feedlot does not impact the biological yield, relative weight and relative value of prime and choice cuts or the relative weight of viscera and other organs.
