Abstrakt: 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.
