选取平均体重为（1.58±0.01）g的健康泥鳅540尾，随机分为6组，每组3个重复，每个重复30尾，对照组饲喂基础饲料，试验A、B、C、D、E组饲料中维生素水平分别为24.375、48.75、97.5、195、390 mg/kg，试验期为30 d。结果表明：当维生素E水平为195 mg/kg时，增重率（WG）、特定生长率（SGR）和蛋白质效率（PER）均达到最大值，饲料系数（FC）达到最小值，分别为112.74%、2.51%、241.23%和2.15，均与对照组差异显著（P＜0.01）。维生素E对泥鳅肠道消化酶活性影响显著，195 mg/kg添加组肠道蛋白酶和淀粉酶活性最高而脂肪酶活性最低，分别为14.96、0.206、20.86 U/g prot，均与对照组差异极显著（P＜0.01）。维生素E分别与增重率、特定生长率、蛋白质效率、饲料系数进行回归分析并考虑维生素E对泥鳅消化酶活性的影响，确定泥鳅幼鱼维生素E适宜需要量为156～196.28 mg/kg。
選取平均體重為（1.58±0.01）g的健康泥鰍540尾，隨機分為6組，每組3箇重複，每箇重複30尾，對照組飼餵基礎飼料，試驗A、B、C、D、E組飼料中維生素水平分彆為24.375、48.75、97.5、195、390 mg/kg，試驗期為30 d。結果錶明：噹維生素E水平為195 mg/kg時，增重率（WG）、特定生長率（SGR）和蛋白質效率（PER）均達到最大值，飼料繫數（FC）達到最小值，分彆為112.74%、2.51%、241.23%和2.15，均與對照組差異顯著（P＜0.01）。維生素E對泥鰍腸道消化酶活性影響顯著，195 mg/kg添加組腸道蛋白酶和澱粉酶活性最高而脂肪酶活性最低，分彆為14.96、0.206、20.86 U/g prot，均與對照組差異極顯著（P＜0.01）。維生素E分彆與增重率、特定生長率、蛋白質效率、飼料繫數進行迴歸分析併攷慮維生素E對泥鰍消化酶活性的影響，確定泥鰍幼魚維生素E適宜需要量為156～196.28 mg/kg。

In this experiment,540 healthy Misgurnus anguillicaudatus with (1.58±0.01)g body weight were randomly divided into 6 groups with 3 replicates of 30 each.The control group was fed with basal diet,the experimental groups were fed the feed with the vitamin E levels of 24.375 mg/kg (A),48.75 mg/kg (B),97.5 mg/kg (C),195 mg/kg (D),390 mg/kg (E),respectively.The experiment lasted for 30 d.The result showed that:When vitamin E level was 195mg/kg diet,the fish had the maximal weight gain,special growth rate,protein efficiency ratio,and the feed coefficient achieved the minimals which were 112.74%,2.51%,241.23% and 2.15 respectively,compared with control group,the difference were significant (P<0.01).In addition,vitamin E had significant effect on activities of digestive enzymes of Misgurnus anguillicaudatus(P<0.05).When vitamin E adding amount was 195 mg/kg,experimental fish had the maximal activities of Protease(14.96 U/mg prot)and Amylase(0.206U/mg prot),and had minimal activities of lipase(20.86 U/g prot),respectively.The conic anal-ysis of weight gain,special growth rate,protein efficiency ratio,feed coefficient and the effect of vitamin E level on activi-ties of digestive enzymes of Misgurnus anguillicaudatus indicated that the optimal vitamin E level of Misgurnus anguilli-caudatus was 156~196.28 mg/kg.
