艾草粉对蛋鸡生产性能、蛋品质、抗氧化功能及粪便评分的影响OA北大核心CSTPCD
Effects of Artemisia argyi powder on production performance,egg quality,antioxidant function,and fecal scores of laying hens
试验旨在研究艾草粉对蛋鸡生产性能、蛋品质、抗氧化功能及粪便评分的影响.试验选取35周龄产蛋率相近的海兰褐蛋鸡1008只,随机分为3组,每组8个重复,每个重复42只蛋鸡.对照组饲喂基础饲粮,试验组分别在基础饲粮中额外添加1%、2%艾草粉.预试期7d,正式试验期56 d.结果显示,各组间产蛋率、破蛋率、蛋重、平均日采食量及料蛋比均无显著差异(P>0.05).1%、2%艾草粉组的蛋壳厚度显著高于对照组(P<0.05),2%艾草粉组的蛋白高度与哈夫单位显著高于其他组(P<0.05).饲粮中添加1%、2%艾草粉能够降低蛋鸡血清丙二醛(MDA)含量,提高谷胱甘肽(GSH)含量及过氧化氢酶(CAT)活性(P>0.05),对蛋鸡粪便评分无显著影响(p>0.05).研究表明,蛋鸡饲粮中添加2%艾草粉可以改善蛋品质,在一定程度上提高抗氧化功能,对产蛋率和粪便评分无不良影响.
This experiment aimed to investigate the effects of Artemisia argyi powder on the production performance,egg quality,antioxidant function,and fecal scores of laying hens.A total of 1 008 Hyline brown laying hens at 35 weeks of age with similar laying rates were randomly divided into three groups,with eight replicates in each group and 42 hens in each replicate.The control group was fed a basal diet,while the experimental groups were supplemented with 1%and 2%Artemisia argyi powder in the basal diet,respectively.The pretrial period lasted for seven days,and the formal experimental period lasted for 56 days.The results showed that there were no significant differences in laying rate,egg breakage rate,egg weight,average daily feed intake,and feed to egg ratio among the groups(P>0.05).The eggshell thickness in the 1%and 2%Artemisia argyi powder groups was significantly higher than that in the control group(P<0.05),and the albumen height and Haugh units in the 2%Artemisia argyi powder group were significantly higher than those in other groups(P<0.05).Dietary 1%and 2%Artemisia argyi powder decreased serum MDA content,increased GSH content and CAT activity of laying hens(P>0.05),had no significant effects on fecal score of laying hens(P>0.05).The study indicates that the addition of 2%Artemisia argyi powder to the diet of laying hens can improve egg quality,enhance antioxidant function to a certain extent,and has no adverse effects on laying rate and feces scoring.
