摘要:

本试验旨在探讨饲粮锰水平对雄性水貂生产性能、血清生化指标及脏器系数的影响。选取120日龄健康、体重相近的雄性水貂75只,随机分为5组,每组15个重复,每个重复1只水貂,分别饲喂基础饲粮中添加0 mg•kg-1(I)、50 mg•kg-1(Ⅱ)、100 mg•kg-1(Ⅲ)、300 mg•kg-1(IV)、600 mg•kg-1(V)锰的试验饲粮。试验期75 d,分别测定水貂生产性能指标,计算脏器系数,测定血清中蛋白质指标、氮代谢指标及相关酶活性。结果表明,试验结束时水貂体重、体长、皮长第Ⅲ组均最高,与IV组差异不显著(P>0.05),但显著高于I组、Ⅱ组和V组(P<0.05),毛皮品质各组间差异不显著(P>0.05);饲粮锰水平对水貂肾脏、肝脏和心脏指数无显著影响(P>0.05);V组和IV组脾脏指数显著高于I组、Ⅱ组和Ⅲ组(P<0.05)。Ⅲ组水貂血清中白蛋白(ALB)和总蛋白(TP)显著高于I组和Ⅱ组(P<0.05),血清中球蛋白(GLOB)含量IV组和V组显著高于I、 Ⅱ和 Ⅲ组(P<0.05),V组最高;Ⅱ组和Ⅲ组血清中天门冬氨酸氨基转移酶(AST)活性显著高于I组(P<0.05),各组丙氨酸氨基转移酶(ALT)活性差异不显著(P>0.05);Ⅱ组水貂血清乳酸脱氢酶(LDH)活性显著低于I组、IV组和V组(P<0.05),Ⅲ组水貂血清中ALP的活性显著高于其他各组(P<0.05),而肌酸激酶(CK)各组之间差异不显著(P>0.05)。由此可见,在本试验条件下饲粮中添加100 mg•kg-1的锰能够提高雄性水貂生产性能,同时提高血清中蛋白含量,以及氮代谢相关酶活性,有利于动物的生长发育,同时对脾没有损害。

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.
