The objective of this study was to evaluate the effect of including levels of the crude glycerin of low purity (0, 6, 12 and 18%) replacing corn in the diets of goats on the carcass characteristics, tissue composition, meat cuts yield and physicochemical parameters of meat. Forty males castrated without defi ned racial pattern goats an initial average weight of 19.70 ± 2.30 kg were slaughtered after 86 days. Diets content 0 and 6% crude glycerin promoted similar responses to the analyzed variables, except for pH and breast weight. No differences were observed to total digestible nutrients, slaughter body weight, commercial cut yield leg tissue composition and physicochemical parameters of meat. Crude glycerin can be included up to 12% without losses on carcass weight and meat cuts, leg composition, and meat quality. The inclusion of crude glycerin containing 63.06% glycerol and 45.57% lipids could be effective in partial replacement of corn in diets for confi ned goats in tropical areas.

Research paper thumbnail of Corn straw replacing sorghum silage in lamb diets in semiarid regions: growth performance, apparent digestibility, and economic viability

Thirty-six Santa Inês x Dorper male lambs were used. The replacement decreased linearly dry matter, organic matter, non-fibrous carbohydrate, and total digestible nutrient intakes. The coefficients of apparent digestibility of dry matter, organic matter, and total carbohydrates increased linearly. Total and daily weight gain decreased linearly. The substitution of sorghum silage by corn straw promotes a positive economic indicator and a significant weight gain, which justifies its use in lamb feeding in semiarid areas.
