摘　　要：试验旨在探讨不同水平的艾叶粉对京红1号蛋鸡产蛋性能、蛋品质及生殖激素的影响。选择54周龄健康的京红1号蛋鸡1000只,随机分为5组,每组10个重复,每个重复20只蛋鸡。对照组蛋鸡饲喂基础日粮,各艾叶粉组分别在基础日粮中添加0.5%、1.0%、1.5%和2.0%的艾叶粉。预试期1 w,正式试验期8 w。结果显示,1.5%组和2.0%组蛋鸡的产蛋率、平均蛋重、平均日产蛋重均显著高于对照组(P<0.05),料蛋比显著低于对照组(P<0.05)。1.5%组、2.0%组鸡蛋的蛋壳强度、哈夫单位显著高于对照组(P<0.05),1.0%组、1.5%组和2.0%组鸡蛋的蛋黄颜色显著高于对照组(P<0.05)。1.5%组和2.0%组蛋鸡雌二醇、黄体酮水平显著高于对照组(P<0.05),1.0%组、1.5%组、2.0%组蛋鸡促卵泡激素、T4水平显著高于对照组(P<0.05)。1.0%组、1.5%组、2.0%组蛋鸡血清过氧化氢酶和超氧化物歧化酶活性显著高于对照组(P<0.05),1.5%组和2.0%组蛋鸡血清丙二醛含量显著低于对照组(P<0.05)。研究表明,饲喂适量的艾叶粉可以显著改善京红1号蛋鸡产蛋性能、蛋品质,调节机体的生殖激素水平,且艾叶粉的适宜添加水平为1.5%~2.0%。The study was to investigate the effect of different levels of Artemisia argyi powder on the laying performance,egg quality and reproductive hormones of Jinghong No.1 laying hens.A total of 1000 healthy Jinghong No.1 laying hens aged 54 weeks were randomly divided into five groups,with 10 replicates in each group and 20 laying hens in each replicate.Laying hens in the control group were fed with a basal diet,and the Artemisia argyi powder groups were supplemented with 0.5%,1.0%,1.5%and 2.0%Artemisia argyi powder,respectively.The pre-test period was 1 w,and the formal test period was 8 w.The results showed that the laying rate,average egg weight and average daily egg weight of laying hens in the 1.5%group and 2.0%group were significantly higher than those in the control group(P<0.05),and the feed to egg ratio was significantly lower than that in the control group(P<0.05).The shell strength and Haugh unit of eggs in the 1.5%group and 2.0%group were significantly higher than those in the control group(P<0.05).The yolk color of eggs in the 1.0%group,1.5%group,and 2.0%group was significantly higher than that in the control group(P<0.05).The levels of estradiol and progesterone in the 1.5%group and 2.0%group were significantly higher than those in the control group(P<0.05).The levels of follicle-stimulating hormone and T4 in the 1.0%group,1.5%group and 2.0%group were significantly higher than those in the control group(P<0.05).The serum activity of catalase and superoxide dismutase in the 1.0%group,1.5%group and 2.0%group were significantly higher than those in the control group(P<0.05),and the serum content of malondialdehyde in the 1.5%group and 2.0%group were significantly lower than those in the control group(P<0.05).The experiment indicates that feeding appropriate amount of Artemisia argyi powder can significantly improve the laying performance and egg quality of Jinghong No.1 laying hens and regulate the levels of reproductive hormones,and the appropriate addition level of Artemisia argyi powder is 1.5%~2.0%.
