Abstract
To determine the appropriate zinc sources and levels in the fodder for mink ,we evulated theeffects of different zinc sources and levels on the performance and digestibility of mink ,.Seventy weaned mink which weres 150 days old were selected .To study the performance and di-gestibility on the Zinc sources and Zinc levels .2 factors and 4 levels random design was conducted in the experiment .Two zinc sources(Zn-Met and ZnSO4·7H2O) were 0mg/kg ,20mg/kg ,30mg/kg and 40mg/kg .The minks were divided into 7 groups and each group have 10 indi-viduals .The feeding and balance trails were carried out .The results showed that adding different sources and levels zinc can improve nutrient di-gestibility .Daily weight gain for 40mg/kg ZnSO4·7H2O and 20mg/kg Zn-Met supplementing group was slight than other groups .The optimal level was ZnSO4 ·7H2 O 40mg/kg or Zn-Met 20mg/kg .关键词
