Abstract

SUASSUNA, Juraci Marcos Alves et al. Carcass characteristics of lambs fed diets containing silage of different genotypes of sorghum. R. Bras. Zootec. [online]. 2014, vol.43, n.2, pp.80-85. ISSN 1806-9290.  https://doi.org/10.1590/S1516-35982014000200005.

Thirty-five feedlot lambs (without defined breed, aged between 5 and 7 months, with average live weight of 17.7±3.7 kg) were used in a completely randomized design to evaluate the effect of diets containing different genotypes of sorghum on morphometric measurements and qualitative characteristics of carcass and yields of primal cuts. The animals stayed in individual indoor pens for 42 days and slaughtered at an average weight of 26.24 kg. No significant differences were observed on morphometric measurements, hot (11.67 kg) and cold (11.39 kg) carcass weight, hot (44.46%) and cold (43.37%) carcass yields, biological yield and on cooling losses. There was also no significant effect of silages of different genotypes of sorghum on the weights and yields of retail cuts (neck, shoulder, rib, loin and leg) and on the subjective evaluation of carcasses. It is possible to finish sheep without defined breed feeding them diets based on silages of sorghum, resulting in carcasses with high yield and good conformation.
