复合酶制剂对产蛋鸡生产性能的影响

The Effect of Compound Enzyme Preparation on Performance of Layers

选用41周龄的海兰褐商品蛋鸡1200只,随机分成两组,每组600只。组内设3个重复,每个重复200只。对照组喂基础日粮,试验组喂基础日粮+0.1%蛋鸡用复合酶制剂,试验期28d。结果表明在产蛋鸡的基础日粮中添加0.1%的复合酶制剂可以使产蛋率平均提高6.12%(P<0.05),料蛋比降低11.69%(P<0.05)。说明在蛋鸡的基础日粮中添加适当的复合酶制剂能促进蛋鸡消化吸收,降低饲养成本,提高饲料转化率和经济效益。

<Abstrcat> 1200 Hy-Line brown of 41 weeks old which were randomly divided into two groups, which there are 600 layers divided into three repeats in each group and 200 layers in each repeat. The control group was fed basal diet, the trial group was administered 0.1% enzyme preparation for use to the layers within 28-day experimental period. The result showed that adding 0.1% the complex enzyme preparations to the basal diet can make the mean egg production rate increase by 6.12% (P<0.05), rate of feed / egg reduce by 11.69% (P<0.05). The result indicated that adding proper complex enzyme preparation can promote digestion, reduce feeding cost and increase the feed conversion ratio and economic benefits in the basal diet quantity of the layers.
