摘要
选用270日龄的海兰褐蛋鸡随机分成两组作为试验材料,研究饲料中添加不同剂量的酶制剂对产蛋性能的影响。结果表明,在基础日粮中加入0.4%的酶制剂,可使产蛋率提高7.51%(P<0.05)、开产日龄在正常范围内提前8.5～9d、料蛋比降低7.60%(P<0.05)、蛋重增加5.13%(P<0.05)。饲养成本明显降低,腹泻现象减少或停止。
To investigate the effects of enzyme preparation on performance of layers,270-day-old Hy-line brown layers were assigned randomly into two groups.Supplementation of enzyme preparation at a level of 0.4% increased laying rate by 7.51%（P〈0.05）,made age at the first laying be 8.5-9 d earlier than expected,reduced feed-egg ration by 7.60%（P〈0.05）,increased average egg weight by 5.13%（P0.05）,largely decreased feed cost and reduced or stopped the occurrence of diarrhea.
