艾草粉对蛋鸡生产性能、蛋品质、血清生化和抗氧化指标的影响

Effects of Artemisia argyi Powder on Performance,Egg Quality,Serum Biochemical and Antioxidant Indices of Laying Hens

本试验旨在研究艾草粉对蛋鸡生产性能、蛋品质、血清生化和抗氧化指标的影响。试验选用180只40周龄健康产蛋期京粉1号蛋鸡作为试验动物,随机分成3个组,每组6个重复,每重复10只鸡。对照组饲喂基础饲粮,其余2组分别使用不同来源的1号艾草粉和2号艾草粉替代基础饲粮中的小麦麸,替代量均为3%。预试期7 d,正试期56 d。结果表明:1)与对照组相比,饲粮添加艾草粉显著提高了蛋鸡产蛋率(P<0.05),其中1号艾草粉组蛋鸡产蛋率显著高于对照组(P<0.05);饲粮添加艾草粉显著降低了蛋鸡料蛋比(P<0.05)。2)试验第28天,与对照组相比,饲粮添加艾草粉显著提高了鸡蛋蛋黄颜色(P<0.05),其中1号艾草粉组鸡蛋蛋黄颜色显著高于对照组(P<0.05)。3)与对照组相比,饲粮添加艾草粉显著提高蛋鸡血清谷胱甘肽含量和过氧化氢酶活性(P<0.05),其中2号艾草粉组蛋鸡血清谷胱甘肽含量和过氧化氢酶活性显著高于对照组(P<0.05)。由此可见,饲粮添加3%艾草粉能够提高蛋鸡生产性能,改善蛋品质,增强蛋鸡抗氧化能力。

The purpose of this study was to study the effects of Artemisia argyi powder on performance,egg quality,and serum biochemical and antioxidant indices of laying hens.A total of 180 healthy 40-week-old Jingfen No.1 laying hens were selected as experimental animals,which were randomly divided into 3 groups with 6 replicates in each group and 10 chickens in each replicate.The hens in the control group were fed a basal diet,and those in the other two groups were fed the diets using different sources of Artemisia argyi powder(No.1 and No.2 Artemisia argyi powder)to replace the wheat bran with the substitution amount of 3%in the basal diet,respectively.The preparatory experiment period was 7 days,and the experiment period was 56 days.The results showed as follows:1)compared with the control group,dietary Artemisia argyi powder significantly increased the laying rate of laying hens(P<0.05),and the laying rate in the No.1 Artemisia argyi powder group was significantly higher than that in the control group(P<0.05);dietary Artemisia argyi powder significantly reduced the feed to egg ratio of laying hens(P<0.05).2)At day 28 of the experiment,compared with the control group,dietary Artemisia argyi powder significantly increased the egg yolk color of laying hens(P<0.05),and the egg yolk color in the No.1 Artemisia argyi powder group was significantly higher than that in the control group(P<0.05).3)Compared with the control group,dietary Artemisia argyi powder significantly increased the serum glutathione content and catalase activity of laying hens(P<0.05),and the serum glutathione content and catalase activity in the No.2 Artemisia argyi powder group was significantly higher than that in the control group(P<0.05).It can be seen that dietary 3%Artemisia argyi powder can improve the performance and the egg quality,and enhance the antioxidant ability of laying hens.
