摘要
试验采用单因子完全随机试验设计,研究不同水平维生素E对北京鸭生产性能的影响,进而探讨0～14日龄北京鸭维生素E的需要量。试验一维生素E水平为0、5、10、20、40、100IU/kg和400IU/kg,选取392只1日龄健康雄性北京鸭随机分为7个处理组,每处理组8个重复,每重复7只。试验二采用半纯合日粮,维生素E水平为0、10、20IU/kg和100IU/kg,选取192只1日龄健康雄性北京鸭随机分为4个处理组,每处理组6个重复,每重复8只。饲养期均为14d。试验结果表明:维生素E可提高0～14日龄北京鸭生产性能,以日增重为评价指标,北京鸭维生素E最低需要量为10IU/kg。
The experiments were conducted to study the effects of vitamin E on growth performance, and vitamin E requirement of 0- 14 days old Peking ducks by completely randomized design.With similar body weight in experiment I , 392 male white peking ducks with one-day old were allotted into seven treatments, each included 8 replicates and one replicate with 7 ducks.Seven levels of dietary vitamin E in experiment I were 0,5,10,20,40,100 IU/kg and 400 IU/kg respectively.ln experiment H , 192 male white Peking ducks with one-day old were allotted into four treatments,each in- cluded 6 replicates and one replicate with 8 ducks.Four levels of dietary vitamin E in experiment I1 were 0,10,20 IU/kg and 100 IU/kg respectively.The trial period was 14 days.The results showed that vitamin E could improve peking ducks＇ performance during 0 ~ 14 days and the vitamin E requirement according to daily weight gain was no less than 10 IU/kg.
