Abstract: Zinc methionine (Zn-Met) with levels of 0 (group Ⅰ), 15 (group Ⅱ), 30 (group Ⅲ), 45 (group Ⅳ), 60 (group Ⅴ), 75 mg/kg (group Ⅵ) and zinc sulfate with the level of 60 mg/kg (group Ⅶ) respectively, were used to evaluate the effects of different zinc levels in male mink in the growing period. The results showed that dry matter digestibility, protein digestibility, fat digestibility in group Ⅳ were significantly higher than that in other groups (P<0.05); minks in different groups had no significant difference in feed intake, dry matter intake, nitrogen intake, urine nitrogen, nitrogen retention, net protein utilization, net protein utilization and biological value of protein (P>0.05).

Key words: mink; zinc; zinc levels; digestibility; nitrogen metabolization
