摘　　要：试验旨在研究槲皮素对蛋鸡蛋壳品质的影响。选择体重和产蛋率相近的240只29周龄蛋鸡,随机分4组,每组6个重复,每个重复10只。对照组饲喂基础日粮,试验1、2、3组分别在基础日粮中添加0.02%、0.04%、0.06%槲皮素。结果表明:①与对照组相比,产蛋高峰期试验2组的蛋壳相对重极显著提高(P<0.01);在产蛋后期各试验组的蛋壳厚度均显著提高(P<0.05),试验2、3组的蛋壳相对重分别提高0.27%(P<0.05)和0.48%(P<0.01),试验1、2组的鸡蛋破软壳率极显著降低(P<0.01)。②产蛋高峰期各试验组的蛋壳钙含量均显著升高(P<0.05);产蛋后期试验2、3组的蛋壳钙含量显著提高(P<0.05),试验3组蛋壳磷含量显著降低(P<0.05)。③产蛋高峰期和后期各试验组的血清钙含量均极显著提高(P<0.01);在产蛋高峰期试验2组的血清碱性磷酸酶(ALP)含量极显著提高(P<0.01);在产蛋后期试验1组的血清ALP含量极显著降低(P<0.01),试验2、3组的血清羟脯氨酸(Hyp)含量均显著降低(P<0.05)。因此,0.04%槲皮素可有效改善产蛋后期蛋壳品质。Effect of quercetin on eggshell quality in laying hens was studied. 240 of 29 week-old laying hens with similar weight and laying rate were randomly divided into 4 groups, 6 replicates each group and 10 hens each replicate. The control group was fed the basal diet,the experimental 1 to 3 groups were fed the basal diet supplemented with 0.02% ,0.04% ,0.06% quercetin. The results showed that compared with the control group, the experimental 2 group significantly improved relative eggshell weight during the laying peak period （P〈0.01）. During the late laying period, the eggshell thickness of the experimen- tal 1,2 and 3 groups significantly increased （P〈0.05）, relative eggshell weight of the experimental 2 and 3 groups significantly increased by 0.27% （P〈0.05） and 0.48% （P〈0.01）, the experimental 1 and 2 groups significantly decreased rate of broken and soft eggs （P〈0.01）. In eggshell, calcium content of the experimental 1,2 and 3 groups significantly increased （P〈0.05） during the laying peak period. Calcium content of the experimental 2 and 3 groups significantly increased （P〈0.05） and the ex- perimental 3 group significantly decreased phosphorus content （P〈0.05） during the late laying period. Quercetin groups significantly increased serum calcium content during the laying peak period and the late laying period （P〈0. 01）, serum alkaline phosphatase content of the experimental 2 group significantly increased during the laying peak period （P〈0.01）, serum alka- line phosphatase content of the experimental 1 group significantly decreased （P〈0.01）, serum hydroxyproline content of the experimental 2 and 3 groups significantly reduced during the late laying period （P〈0.05）. In conclusion,0.04% quercetin effectively improved eggshell quality of laying hens during the late laying period.
