日粮中添加酶制剂对樱桃谷肉鸭生产性能的影响

Effect of adding enzyme preparation into maizebean cake diet on productivity of cherry valley broiler ducks

选用 12 0 0羽刚出壳的樱桃谷肉鸭 ,依性别随机分为 2组 ,每组设 4个重复 (每个重复 15 0羽鸭 ,公母各半 ) ,一组为对照组 ,饲喂基础日粮 ,另一组为试验组 ,在基础日粮中添加 0 .1%华芬 15 11型肉鸭用复合酶。试验结果表明 :华芬 15 11型肉鸭用复合酶可以极显著地提高樱桃谷肉鸭的日增重 (P <0 .0 1) ,0～ 4 5日龄日增重提高 7.4 4 % ;能显著提高饲料利用率 (P <0 .0 5 ) ,0～ 4 5日龄饲料效率提高 7.38% ;能获取较好的经济效益 (提高毛利润 4 7.5 4 % )。

just hatched Cherry Valley broiler ducks are divided into two groups according to their sex with four repeats in each group.There are 150 ducks in every repeat in which half is male and half is female . Group 1 raised foundation diet is used as comparison one . Group 2 as test one added 0.1% of Huafen 1511 type enzyme preparations into the foundation diet . Outcome is that the 1511 type enzyme preparations of broiler ducks have distinctly daily weight gain (P<0.01) . And the daily weight gain rises up to 7.44%, and the feed conversion efficiency is distinctly improved (P<0.05) 7.38% during from birth to 45 days . So ecnomic efficiency is better .
