【摘要】 试验旨在为研究中草药饲料添加剂对鸡蛋品质的影响。选择产蛋率约为83%的42周龄海兰褐商品蛋鸡300只,随机分为6个处理,每个处理5个重复,每个重复10只。对照组饲喂基础日粮,Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ组分别在对照组的基础上添加中草药添加剂1%、2%、3%、4%、5%。试验结果表明,处理组Ⅳ蛋重与对照组相比极显著增加(P<0.01),其他各处理组间差异不显著(P>0.05);Ⅴ组蛋黄颜色最深(P<0.01),不同的添加水平对蛋型指数、哈氏单位、蛋壳厚度、蛋壳重无显著影响(P>0.05);Ⅴ组蛋黄中的胆固醇含量明显下降(P<0.01),各试验组粗蛋白质、磷、钙、粗脂肪、磷脂与对照组均无显著差异(P>0.05)。同时随着饲喂时间的延长,不同采样时间Ⅱ、Ⅲ、Ⅳ、Ⅴ组蛋黄中的粗蛋白质含量显著增加(P<0.05),提高了鸡蛋的营养价值。因此,饲料中添加中草药4%~5%,可以在一定程度上改善鸡蛋品质。更多还原

【Abstract】 To study influence on egg quality by Chinese herbal medicine feed additives.Three hundreds Hyline brown hens (42 weeks and 85% laying rate)were chosen to be randomly divided into 6 groups,with 5 replicates in each group and 10 hens in each replicate.The control group feed basic dietart,Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ group feed 1%,2%,3%,4%,5% of herbal medicine additive adding on control group basic dietart respectively.The result showed that the weight of egg of group Ⅳ was highly significant than the control group(P<0.01),there was no obvious between the other groups(P>0.05);the group Ⅴ was the best yolk colour(P<0.01),there was no obvious different egg shape index,HU,eggshell thickness,shell weight by different adding level(P>0.05);the egg yolk cholesterol content of groups Ⅴ level decreased obviously(P<0.01),crude protein,calcium,phosphorus,crude fat,phospholipids were no obvious significant different between test groups and the the control group(P>0.05).The crude protein content of egg yolk of group Ⅱ,Ⅲ,Ⅳ,Ⅴ(P<0.05)increased significantly in different sampling time while feeding time prolonged,improving the eggs nutritional value.Thus,egg quality was improved to some extent by adding Chinese herbal medicine feed additives 4%-5% in feed.更多还原
