不同剂量生姜粉与中草药复方联合对蛋鸡生产性能及蛋品质的影响

摘要

[Objective]To enhance the application effect of Chinese herbal medicine in laying hens.[Method]220 25-week-old Roman pink-shell laying hens were randomly divided into 5 groups:control group(K),Chinese herbal medicine group (CK)，ginger powder groups (A,B,C).Different amounts of ginger powder were added in the Chinese herbal medicine to study their combined effects on the productiton performance and egg quality of laying hens.[Result]The daily feed intake,laying rate,and average egg weight in group A improved by 1.15%,6.20% and 1.44% than group CK respectively.The feed-egg ratio and broken egg rate reduced by 6.25% and 47.69% than group CK respectively.The broken egg rate in group B and group C increased by 95.38% and 112.31% than group CK respectively.The egg shape index,eggshell thickness,eggshell strength,Haugh unit,yolk ratio,eggshell ratio and yolk color in group A,group B,group C had no significant difference with group CK.[Conclusion]Adding appropriate amount of ginger powder in Chinese herbal medicine compound can reduce feed-egg ratio and improve laying rate.The optimal addition amount of ginger powder was 5 g/kg.%[目的]提高中草药在蛋鸡生产中的应用效果.[方法]将220只25周龄的罗曼粉壳蛋鸡随机分为5组:对照组(K)、中草药组(CK)、生姜粉组(A、B、C).在中草药配方中加入不同剂量的生姜粉,探讨二者联合作用对蛋鸡生产性能和蛋品质的影响.[结果]A组平均日采食量、产蛋率和平均蛋重较CK组分别增加了1.15%、6.20%和1.44%,料蛋比和破蛋率分别比CK组降低了6.25%和47.69%.B、C组破蛋率比CK组分别增加了95.38%和112.31%;A、B、C组蛋形指数、蛋壳厚度、蛋壳强度、哈夫单位、蛋黄比例、蛋壳比例、蛋黄颜色与CK组相比均无显著差异(P>0.05).[结论]在中草药复方中添加适量的生姜粉,能够降低料蛋比,提高产蛋率,生姜粉的添加量以5 g/kg最佳.
