| 摘 要： | 试验以５００只１４３日龄,产蛋率１５％的京白“９０４”母鸡为材料,研究饲料中添加不同剂量的复合酶制剂对产蛋性能的影响。结果表明,在基础日粮中加入０．５％的复合酶制剂,可使产蛋率提高１５％左右（Ｐ＜０．０１）;开产日龄在正常范围内提前７～８ｄ;饲料消耗减少１５．１１％（Ｐ＜０．０１）;蛋重增加１８．１８％（Ｐ＜０．０１）。饲养成本明显降低,拉稀减少或停止。

| Abstract: | Data from 50"Jing White 904"layers at 143 days with 15% of laying rate was analyzed to study the influence of compound emzyme preparation on laying performance of layers.The result showed that by adding"Juwei"compound emzyme the laying rate raised about 15 % (p<0.01);the date of starting laying was 7-8 days earlier;feeding stuff comsumption reduced 15.11%(P<0.01);and the average weight of egg increased 18.18%(p<0.01).There was a marked drop or stop in diarrhoea. |
