和美酵素代替油脂对矮小型蛋鸡生产性能的影响

Effects of Hemicelluloses instead of Oil on Performance of Dwarf Hens

用4种饲料在冬季饲养矮小型蛋鸡,A组为对照组,使用不加油或和美酵素的基础日粮;B组日粮是基础日粮添加0.5%油脂和500g/T和美酵素;C组日粮是基础日粮添加油脂;D组日粮是在基础日粮基础上加500g/T和美酵素,实验期11周。结果表明,使用基础日粮加和美酵素的D组产蛋率最高穴77.7%雪,和其它3个组差异显著(P<0.05雪,实验期料蛋比2.21押1熏每只鸡毛利3.52元,比对照组和加油组分别高0.45元和0.79元。结果也表明熏在代谢能较高的饲料中添加和美酵素,会使矮小型鸡的体重显著增加,并不能显著提高产蛋水平,因此和油脂同时使用效果不好。

Four types of feeds were used to feed dwarf hens in winter for11weeks.Group A was the control group using the base feed which didn't adding any fat or Hemicelluloses.Group B feed the base feed adding0.5%fat and Hemicelluloses500g/T.Group C is the base feed adding suitable fat.Group D is base feed adding Hemicelluloses500g/T.The results showed that the egg production of group D is significantly higher than other three groups(p<0.05).FCR of group D is2.21:1and the gross profit per hen gets3.52yuan during the testing period,respectively0.45yuan and0.79yuan more than group A and group C.The result also shows that it's not good to add Hemicelluloses in the higher ME feed.
