用添加0、25、50、100和200 ppm CuSO 4的日粮饲喂自然黑水貂。5 H2O处理153或357 d。短期铜补充水貂体重增加或血红蛋白或红细胞压积浓度没有显着的有益或不利影响，虽然血浆铜浓度略有升高，水貂美联储添加铜。肝脏铜浓度显着增加，只有在水貂喂200 ppm铜。肝脏锌和铁的浓度没有受到影响的添加铜。深色毛皮中观察到的雄性动物喂食较高水平的铜。长期补充铜的水貂的繁殖性能没有受到不利影响，虽然更大的套件死亡率和减少“窝质量”是由于较高的铜浓度。硫酸铜和醋酸铜对成年水貂ip急性（21-d）LD_（50）分别为7.5和5.0 mg/kg。
Natural dark mink kit were fed a diet supplemented with 0, 25, 50, 100 or 200 ppm Cu from CuSO4 . 5H2O for 153 or 357 d. The shorter term Cu supplementation had no significant beneficial or adverse effects on mink body weight gains or hemoglobin or hematocrit concentrations, although plasma Cu concentrations were slightly elevated in the mink fed added Cu. Liver Cu concentrations were significantly increased only in the mink fed 200 ppm Cu. Liver Zn and Fe concentrations were not affected by the added Cu. Darker fur was observed in pelted males fed the higher levels of Cu. The reproductive performance of mink on the longer term Cu supplementation was not adversely affected, although greater kit mortality and reduced "litter mass" were a result of the higher Cu concentrations. The acute (21-d) ip LD50 concentrations of Cu sulfate and Cu acetate in adult mink were 7.5 and 5.0 mg/kg, respectively.
