Abstract:

The experiment was conducted to study the effect of the different dietary Manganese (Mn) levels on production performance,blood serum biochemical parameters and organ index in male mink.Seventy-five healthy male minks with samilar weight were randomly divided into 5 groups with 15 replicates per group and 1 mink per replicate.0 mg•kg-1(I),50 mg•kg-1(Ⅱ),100 mg•kg-1(Ⅲ),300 mg•kg-1(IV)and 600 mg•kg-1(V)of Mn levels were added in basic diet.The trial lasted for 75 d.Production performance was examined,organ index was calculated and proteins indices,nitrogen metabolism indices,enzymes activity of serum were determined.The results showed that,body weigh,body length and pelt length were highest in group Ⅲ,and they were similar between group Ⅲ and IV (P>0.05),but significantly higher in group Ⅲ than that in group I,Ⅱ and V(P<0.05).Liver index,heart index and kidney index were not significantly affected by dietary Mn levels (P>0.05),spleen index of group IV and V were significant higher than that of group I,Ⅱ and Ⅲ (P<0.05).The content of albumin (ALB) and serum total protein (TP) in group Ⅲ were significantly higher than that in group I and Ⅱ (P<0.05),the content of serum globulin in IV and V groups were significantly higher than that in group I,Ⅱ and Ⅲ (P<0.05),and the highest one was in V group.The activity of serum AST in group Ⅱ and Ⅲ were significantly higher than that in group I (P<0.05),the activity of LDH in group I,IV and V were significantly higher than that in group Ⅱ (P<0.05),the activity of ALP in group Ⅲ was significantly higher than that in other groups (P<0.05 ),CK was similar among all groups (P>0.05).In conclusion,under this experimental conditions,when the diet supplementation with 100 mg•kg-1 Mn,the minks had the best production performance and relatively higher protein synthesis rate,enzyme activity and it also could improve the growth performance and no damagement on the spleen of male mink.
