The objective of the study was to evaluate whether crude glycerin (CG), which was supplied as a dietary ingredient for growing lambs, affected the macro- and micromineral contents of the longissimus lumborum (LL). Twenty-four lambs were placed in two treatments: animals that received no CG and animals that received CG as part of their diet. The experiment lasted for 56 days. The phosphorus, potassium, magnesium, calcium and chromium contents in the LLs of the lambs were not significantly different between the groups. Cadmium, nickel and lead were not detected in the LLs of lambs fed CG. The zinc, iron and copper contents decreased in the LLs of lambs fed CG (approximately 10%, 14%, and 30%, respectively) (P ≤ .03). The sodium content in the LLs increased with the inclusion of CG in the diet (11%) (P = .029). We concluded that the zinc, iron and copper contents decreased in the LLs of the lambs fed CG and sodium content increased.

这项研究的目的是评估粗甘油（CG）作为生长羔羊的饮食成分是否会影响长腰肉（LL）的宏观和微量矿物质含量。将24只羔羊置于两种处理中：不接受CG的动物和接受CG作为饮食一部分的动物。实验持续了56天。羔羊的LL中磷，钾，镁，钙和铬的含量在两组之间无显着差异。在饲喂CG的羔羊的LL中未检测到镉，镍和铅。饲喂CG的羔羊的LL中锌，铁和铜含量下降（分别约为10％，14％和30％）（P ≤.03）。随着饮食中添加CG（11％），LL中的钠含量增加（P  = .029）。我们得出结论，饲喂CG的羔羊的LL中锌，铁和铜含量降低，而钠含量增加。
