Carcass characteristics and meat quality of lambs fed high concentrations of crude glycerin in low-starch diets
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±3.56kg BW) were assigned to a randomized complete block design wit...

Zusammenfassung: | 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±3.56kg 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 38kg after 72±20days. 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 CLA tended to increase in glycerin-fed lambs (P=0.06). Crude glycerin decreased stearic, palmitic, transvaccenic, total saturated fatty acids, and atherogenicity index (P |
