摘　　要：为研究饲粮中添加维生素A对种鹅肝脏维生素A含量、免疫性能和抗氧化性能的影响,选取体重相近的180日龄扬州鹅种公鹅15只,随机分为5组(Ⅰ组、Ⅱ组、Ⅲ组、Ⅳ组、Ⅴ组),每组3只。Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ组试验鹅在基础饲粮中分别添加0、4000、8000、12000、16000 IU/kg维生素A。结果表明:(1)16000 IU/kg维生素A添加组肝脏维生素A含量显著高于0、4000、8000、12000 IU/kg添加组(P <0.05)。(2)从免疫和抗氧化性能来说,扬州种公鹅饲粮中维生素A的适宜添加量为8000~12000 IU/kg。维生素A含量过多或过少都会对种公鹅生长产生不利影响。The purpose of this experiment was to study the effect of vitamin A on the content of vitamin A,immunity and antioxidation in liver of geese.15 male Yangzhou geese of 180 days old were randomly divided into 5 groups(Ⅰgroup,Ⅱgroup,Ⅲgroup,Ⅳgroup,Ⅴgroup)with 3 in each group.GroupsⅠ,Ⅱ,Ⅲ,ⅣandⅤadded 0,4000,8000,12000,16000 IU/kg vitamin A to the basic diet respectively.The results showed that:(1)The vitamin concentration of 16000 IU/kg group was significantly higher than that of0,4000,8000,12000 IU/kg groups(P<0.05).(2)From the aspect of immunity and antioxidation,the suitable amount of vitamin A in Yangzhou male geese was 8000~12000 IU/kg.Too much or too little vitamin A had a negative effect on the growth of male geese.
