复合酶和植酸酶对商品肉鸡生产性能及环境的影响

目的 研究复合酶和植酸酶对商品肉鸡生产性能及环境的影响。方法 研究选择1日龄AA肉仔鸡1600只，随机分成4个处理，每个处理4个重复。对照组喂基础日粮，试验1、2、3组分别在基础日粮中加入0.1%的复合酶、0.01%的植酸酶、0.1%的复合酶＋0.01%的植酸酶。结果 日增重和饲料效率试3组最好，其次是试1组，试2组第3，对照组最低(p＞0.05)；鸡粪尿中氮含量试1、2、3组较对照组分别下降了10.21%、5.64%、12.04%，磷含量试1、2、3组较对照组分别下降了2.04%、30.61%和31.63%；舍内氨含量试1、2、3组较对照组分别下降了20.48%、13.07%和26.98%；舍内硫化氢浓度试1、2、3组分别较对照组下降了19.66%、15.10%和29.30%。结论 复合酶和植酸酶能改善肉鸡的生产性能和减少污染物质的排放量。

Effect of Phytase and Compound Enzymes on Performance of Broilers and Environment

Objective] To investigate the effect of Phytase and Compound Enzymes on Performance of Broilers and Environment;Methods]1600 one-day AA broilers were randomly allocated to 4 treatments with 4 replicates.Control group with base diet,experimental group 1,2 and 3 with adding 0.1% Compound Enzymes,0.01% Phytase and 0.1% Compound Enzymes 0.01% Phytase in base diet respectively.Results:compared with Control group,daily gain and feed efficiency in group 3 is best,then group 1 and group 2.Result]The fecal nitrogen in group 1,2,3 decreased 10.21%,5.64% and 12.04% respectively,faecal phosphorus in group 1,2,3 decreased 2.04%,30.61% and 31.63% respectively;the ammonia of henhouse in group 1,2,3 decreased 20.48%,13.07% and 23.98%,the sulfureted hydrogen of henhouse in group 1,2,3 decreased 19.66%,15.10% and 29.30% respectively.Conclusion] Phytase and Compound Enzymes improve performance of broilers and decrease pollute substance release.
