Carcass traits of goats finished with different levels of concentrate supplementation and kept on caatinga enriched with Urochloa trichopus

Abstract The objective of this study was to evaluate the carcass traits crossbred F1 goats (Boer x non-descript breed) finished on thinned caatinga pasture enriched with signal grass (Urochloa trichopus Stapf.), and receiving supplementation. Twenty-four 27.00 ± 3.32 kg body weight were used. supplement designed meet nutritional requirements animals highest supplementation level could gain 150g per day. For data analysis, a completely randomized design adopted, four treatments (supplementation levels 0.0%; 0.5%; 1.0% 1.5% weight) six replications (animals). Data subjected analysis variance regression. Supplementation resulted in an increasing linear effect for slaughter weight, hot cold empty yield yield; quadratic biological yield. Weight loss by cooling not influenced results subjective evaluations, only conformation (P<0.05). morphometry, positive found thorax perimeter, croup width, width. caused most non-edible components, there no influence variables It can be concluded that up kept higher
