选用17日龄临床健康、体重相近双鬼头肉鸭250羽,随机分5个处理,每个处理5个重复,每个重复10羽,分别饲以日粮A(正常磷水平组,有效磷0.30%)、B(低磷水平组,有效磷0.20%)、C(B+I酶,200g/t)、D(B+酶Ⅱ,200g/t)和E(B+酶Ⅲ,200g/t和酶Ⅳ,100g/t)5种不同日粮,进行了30天的饲养试验.结果表明:在本试验条件下,酶制剂对17-47日龄双鬼头肉鸭的生产性能和经济效益无 显著影响(P>0.05).

Two thousand and fifty hundred clinical healthy 17-day-old ducks with similar weight were randomly divided into 5 treatment groups. Each group was assigned 5 replicates and 10 ducks in each replicate. Ducks were fed with diet A （normal phosphorus level, available phosphorous is 0.30%）, diet B （low phosphorus level, available phosphorous is 0.20%）, diet C （B ＋ enzyme Ⅰ, 200g / t）, diet D （B ＋ Enzyme Ⅱ, 200g / t） and diet E （B ＋ enzyme Ⅲ, 200g / t and enzyme IV, 100g / t） every day respectively for 30 days. The results showed that...
