Glycerol has been evaluated as a safe and promising animal feed. It can replace traditional energy foods and reduce competition with major animal husbandry systems. In this study, 40 fattening Kazakh ewes (18 months of age) were selected to investigate the dynamic response of growth performance, serum biochemical indexes, fat deposition, carcass traits and meat quality to different levels of glycerol (0, 1%, 7%, and 12% DM). The results showed that glycerol could improve sheep growth performance, increase fat deposition, increase carcass dressing percentage and improve meat quality. Among them, the Gly7% group had significant positive effects (P |
