摘要
很多研究表明,铜能够影响反刍动物体内脂质的代谢。在日粮中额外添加铜10~40 mg/kg DM可以降低皮下脂肪组织的厚度和胆固醇浓度,提高背最长肌中不饱和脂肪酸的含量,同时,血清中去甲肾上腺素增加。因此,文章主要讨论了铜影响反刍动物体内脂质代谢的可能机制。
Results from experiments investigating Cu metabolism in ruminants indicate that Cu is involvedin lipid metabolism. Copper supplementation ranging from 10 to 40 mg /kg of DM to diets decreased subcu-taneous adipose tissue deposition and decreased cholesterol concentrations but increased unsaturated fattyacid composition of LM. Serum norepinephrine tended to be greater in Cu-supplemented steers. There-fore, the overall intent of this review is to discuss possible mechanisms whereby Cu may affect lipid me-tabolism in ruminants.
