PINTO, Tiago Ferreira et al. Use of cactus pear (Opuntia ficus indica Mill) replacing corn on carcass characteristics and non-carcass components in Santa Inês lambs. R. Bras. Zootec. [online]. 2011, vol.40, n.6, pp. 1333-1338. ISSN 1806-9290. http://dx.doi.org/10.1590/S1516-35982011000600023.
The objective of this study was to evaluate the biometric and morphometric measures, regional composition, carcass characteristics and non-carcass components of Santa Inês lambs submitted to levels of corn replaced by cactus pear in the diet. It was used 45 Santa Ines non-castrated male lambs, with average initial live weight of 25.50 ± 0.48 kg as a completely randomized block design with five treatments (0; 25; 50; 70 and 100%) and nine replicates. There was an effect of the diet on slaughter weight, empty body weight, hot and cold carcass, cold carcass weight, shoulder weight and loin weight. Cactus pear can replace up to 75% of corn in diets for feedlot Santa Inês lambs, without compromising production, carcass characteristics and production of non-carcass components.
