摘　　要：试验旨在研究不同维生素E水平对骡鸭肝脏L-FABP mRNA表达量的影响。试验选用600只70日龄公骡鸭,随机分为4组:Ⅰ为对照组,Ⅱ、Ⅲ、Ⅳ为试验组,分别在填饲日粮基础上分别添加0、40、90、140 mg/kg的维生素E。预饲期25 d,填饲期13 d。结果表明:填饲结束后,与填饲前相比,肝脏中L-FABP mRNA的相对表达量显著升高(P<0.05);填饲结束后,与对照组相比,Ⅱ、Ⅲ、Ⅳ组肝脏组织中L-FABP mRNA相对表达量显著升高(P<0.05),且Ⅱ组最高。A trial was conducted to study influence of vitamin E supplementation of overfeeding diets on L-FABP gene expression in mule ducks.Six hundred 70-day-old male mule ducks were randomly allocated to 4 groups with 150 ducks per group.Each treatment had three replicates of 50 ducks.Group Ⅰ was control fed with overfeeding diets.Group Ⅱ,Ⅲ and Ⅳ were experimental groups fed on overfeeding diets containing vitamin E 40,90,140 mg/kg,respectively.It showed that the liver L-FABP mRNA relative expression level of 108-day-old ducks increased significantly（P0.05） compared with 95-day-old ducks.After overfeeding,the liver L-FABP mRNA relative expression level of experimental groups were higher than control group（P0.05） and groupⅡwas the highest.
