本试验旨在研究黄精多糖对种鹌鹑生产性能、蛋品质、孵化性能及血清抗氧化指标的影响。选取4 000只产蛋鹌鹑、500只雄性鹌鹑（仅用于配种），随机分为5组，对照组饲喂基础饲粮，试验组饲喂在基础饲粮中分别添加0.4%黄芪多糖及0.1%、0.4%和0.8%黄精多糖的试验饲粮，每组4个重复，每个重复200只产蛋鹌鹑、25只雄性鹌鹑。预试期15 d，正试期30 d。结果表明：1）0.4%黄精多糖组和0.4%黄芪多糖组的产蛋率及平均蛋重均显著大于对照组和0.1%黄精多糖组（P<0.05），0.4%黄精多糖组、0.8%黄精多糖组、0.4%黄芪多糖组平均日采食量、料蛋比均显著小于对照组（P<0.05）。2）各试验组蛋黄色泽均显著高于对照组（P<0.05），0.4%黄精多糖组、0.8%黄精多糖组和0.4%黄芪多糖组哈氏单位显著高于0.1%黄精多糖组和对照组（P<0.05）。3）0.4%黄精多糖组、0.8%黄精多糖组及0.4%黄芪多糖组的受精率、受精蛋孵化率和入孵蛋孵化率都显著大于对照组（P<0.05）。4）0.4%黄精多糖组、0.8%黄精多糖组以及0.4%黄芪多糖组血清总超氧化物歧化酶、谷胱甘肽过氧化物酶活性以及总抗氧化能力均显著大于对照组（P<0.05），血清丙二醛含量均显著小于对照组和0.1%黄精多糖组（P<0.05）。结果提示，饲粮中添加0.4%和0.8%黄精多糖均能提高种鹌鹑生产性能，增加蛋黄色泽和哈氏单位，提高孵化性能，提高血清抗氧化性能，其中以0.4%黄精多糖的效果最佳。

The aim of this study was to investigate the effects of Polygonatum polysaccharide on performance, egg quality, hatching performance and serum antioxidant indexes of quails. A total of 4 000 laying quails and 500 male quails (only for mating) were selected, and randomly divided into 5 groups each group had 4 replicates with 200 laying quails and 25 male quails per replicate. Quails in control group were fed a basal diet, and those in experimental groups were fed the basal diet supplemented 0.4% Astragalus polysaccharide, and 0.1%, 0.4% and 0.8% Polygonatum polysaccharide, respectively. The pre-experiment lasted for 15 d, and the experiment lasted for 30 d. The results showed as follows:1) laying rate and average egg weight of 0.4% Polygonatum polysaccharide group and 0.4% Astragalus polysaccharide group were significantly higher than those of control group and 0.1% Polygonatum polysaccharide group (P<0.05), and average daily feed intake and feed to egg rate of 0.4% Polygonatum polysaccharide group, 0.8% Polygonatum polysaccharide group and 0.4% Astragalus polysaccharide group were significantly lower than those of control group (P<0.05). 2) Yolk color of experimental groups was significantly higher than that of control group (P<0.05), and Haugh unit of 0.4% Polygonatum polysaccharide group, 0.8% Polygonatum polysaccharide group and 0.4% Astragalus polysaccharide group were significantly higher than that of control group and 0.1% Polygonatum polysaccharide group(P<0.05). 3) Fertilization rate, hatching rate of fertilized eggs and eggs of 0.4% Polygonatum polysaccharide group, 0.8% Polygonatum polysaccharide group and Astragalus polysaccharide group were significantly higher than those of control group (P<0.05). 4) Serum total superoxide dismutase and glutathione peroxidase activities, and total antioxidant capacity of 0.4% Polygonatum polysaccharide group, 0.8% Polygonatum polysaccharide group and Astragalus polysaccharide group were significantly higher than those of control group (P<0.05), and serum malondialdehyde content was significantly lower than that of control group and 0.1% Polygonatum polysaccharide group. The results indicate that dietary addition of 0.4% and 0.8% Polygonatum polysaccharide can improve performance of quails, increase yolk color and Haugh unit, improve hatching performance and serum antioxidant function, and the effects of 0.4% Polygonatum polysaccharide are the best.
