木聚糖酶对肉鸭生产性能的影响

实验选取半番鸭作为实验对象。选取1日龄的生长情况基本一致的健康半番鸭200只,随机分为5组,进行对照试验,采用单因子试验设计,在5组半番鸭的日粮中分别添加木聚糖酶50g/t、100g/t、150g/t、200g/t和0g/t,试验为期45d。结果表明:在半番鸭的日粮中添加合适的木聚糖酶剂量,满足其正常的生长发育所需要的环境条件,自由采食和自由饮水,并且搞好饲养管理,半番鸭就能够进行正常的生长发育。最后通过经济效益分析,在半番鸭的日粮中添加150g/t的木聚糖酶可明显的改善半番鸭的生产性能,从而提高饲料的利用率,降低饲养成本。

Xylanase to meat duck production performance influence

This experiment selects the Jianchang duck to take the experimental object.Selects on 7th the age growth situation basic consistent health Jianchang duck 300,divides into 5 groups stochastically,carries on the check experiment,Uses the single factorial experiment design,respectively increases xylanase 50 g/t,100 g/t,150 g/t,200 g/t and 0 g/t in 5 group of Jianchang duck's date grain,the experiment lasts 28 days.The result indicated that,Increases the appropriate xylanase dosage in the Jianchang duck's date ...
