In this study, we evaluated the effects of total corn replacement with crude glycerin on carcass characteristics and meat quality of feedlot lambs fed high-concentrate diets with low starch. Forty non-castrated Santa Ines lambs (23.5 +/- 3.56 kg BW) were assigned to a randomized complete block design with five dietary treatments: 0%, 7.5%, 15%, 22.5%, or 30% crude glycerin, replacing corn. Animals were slaughtered at a BW of 38 kg after 72 +/- 20 days. The addition of up to 30% crude glycerin reduced carcass weight and yield (P <= 0.02). Odd-chain fatty acids, oleic, palmitoleic, total unsaturated, and monounsaturated fatty acids were increased (P <= 0.01) while CIA tended to increase in glycerin-fed lambs (P = 0.06). Crude glycerin decreased stearic, palmitic, transvaccenic, total saturated fatty acids, and atherogenicity index (P < 0.01). High concentrations of crude glycerin in low-starch diets reduced carcass weights, nevertheless improved meat quality by increasing unsaturated and oddchain fatty acid contents.
