| Popis: | The aim was to evaluate the effects of crude glycerin levels (CG) (0, 2.65, 5.33, 8.06 and 10.84% in dry matter basis) on intake, digestibility, performance, carcass morphometric measurements and meat quality of sheep finished in feedlot. Twenty five crossbred Dorper x St. Ines wethers, with 24 ± 2.0 kg average weight were housed in individual pens. The experimental design was completely randomized. Levels of CG in gross diet caused a decreasing linear effect (P 0.05) levels of glycerin on animal performance. For morphometric measurements of carcass and meat characteristics, no significant difference (P>0.05) levels of glycerin for hot carcass weight, chilled carcass weight, hot carcass yield, Chilled carcass yields, loss cooling, state of greasing, carcass length, leg length, depth of leg, chest depth, loin eye area, texture, marbling and color. However, the influence was observed (P |
