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。

Abstract: 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 experimental 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 experimental 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 alkaline 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.
