摘　　要：为探讨不同水平铜对育成期水貂营养物质消化代谢的影响，试验以蛋氨酸螯合铜为铜源对6组86～146日龄雄性水貂基础日粮中添加不同水平的铜，采用全收粪尿法进行消化代谢试验。通过对脂肪代谢率、氮消化率、氮沉积率和氮生物学效价的测定，结果表明：基础日粮中铜添加量为239—249mg／kg时，可显著提高水貂氮和铜的消化率（P〈0．05），但对氮沉积率、氮生物学效价和脂肪代谢率均无显著影响（P〉0．05）。Effect of different Cu levels on digestion and metabolism of mink nutrition was studied experiment. The 86- 146 days male mink of 6 groups were fed with basal diet supplemented with different levels of met-Cu for 60 days. Digestion metabolism experiment was done by Charging of feces. Through testing EE metabolism, N digestive rate, N deposition and biological value of N, the result showed that N and Cu digestive rate could be improved significantly（ P 〈 0.05） when 239 - 249 mg/kg Cu was added in basal diet. There was no obvious effect on N deposition, biological value of N and EE metabolism（ P 〉 0.05）.
