摘 要:本试验旨在研究叶黄素对鹌鹑繁殖性能及母源IgG向后代转移的影响。试验选取1日龄朝鲜龙城父母代鹌鹑144羽,按体质量随机分为4个处理组,每组设3个重复,每个重复12羽。采用小麦-豆粕型基础日粮,分别添加0、50、1001、50 mg.kg-1叶黄素。10周龄时,每个重复取2羽,ELISA法检测血清IgG含量。收集种蛋并孵化,计算孵化率、受精率、死胚率。子代鹌鹑在相同条件下饲养,日粮中不添加叶黄素,分别在1、3、7、14、21日龄时,每重复取2羽心脏采血,检测血清中IgG含量。结果表明:叶黄素可以显著提高种蛋的受精率和孵化率(P<0.05),降低死胚率(P<0.05);对雌鹌鹑血清中IgG的含量没有显著影响(P>0.05),但可以显著提高卵黄IgG水平(P<0.05);子代鹌鹑血清IgG的含量与叶黄素的添加量成正比,高剂量叶黄素可显著提高1日龄血清IgG水平(P<0.05)。结论:叶黄素可以显著改善鹌鹑的繁殖性能,并通过促进母源IgG在卵黄内的沉积从而提高后代血清中IgG水平。This experiment was conducted to study the effects of lutein on reproductive performance and maternal IgG transferring to offspring of quails. 144 1-d-old parental generation North Korea Longcheng quails were randomly divided into four treatments groups with 3 replicates of 12 quails each. Wheat-soybean basal diet was used, and the treatment groups were supplied with 0, 50, 100 and 150 mg·kg-1 lutein. At 10 weeks old age, 2 quails each replicates were randomly selected and serum IgG levels were tested by ELISA. Then fertilized eggs were collected and hatched. Hatching rate, fertilization rate and death rate were calculated. Newly hatched birds were reared under the same condition, but without lutein in basal diet. On d 1, 3, 7, 14 and 21, 2 birds per replicate were selected and serum IgG levels were tested. The results showed that lutein could significantly improve fertilization rate and hatching rate of quails (P〈0.05), significantly reduce death rate of embryos (P〈0.05). Lutein had no significant impact on female quails serum IgG contents (P〉0.05), but could significantly increase IgG deposition in egg yolk (P〈0.05). Serum IgG levels of new hatched quails were correlated with lutein contents in the diet, and 150 mg· kg-1 lutein could significantly increase serum IgG levels of 1-d-old quails (P〈0.05). Conclusion: Lutein could significantly improve reproductive performance of quails, and raise serum IgG level of offspring by promoting maternal IgG deposition in egg yolk.
