| 摘 要： | 将富硒益生菌（Se-enriched probioticS，SP）和亚硒酸钠（SodiumSelenite，SS）2种硒源分别以3个硒水平0．2、0．5和1．0mg／kg添加到蛋鸡基础13粮，进行为期35d的饲养试验。结果表明，13粮添加SP或SS均能显著提高脾硒含量，随着硒添加水平的升高，脾硒含量也显著升高，且添加SP较SS能显著提高脾硒含量；在试验的第14天，添加SS或SP均能显著促进蛋鸡外周血T淋巴细胞转化，且随着硒添加水平的升高，T淋巴细胞的转化增加；在试验的第14和第28天，添加SS或SP均能显著提高蛋鸡血浆IL-2的水平，随着硒添加水平的升高和试验时间的延长，血浆IL-2均升高，且在试验的第28天，添加SP较添加SS能显著提高蛋鸡血浆IL-2的水平。结论：日粮添加SS或SP均能提高蛋鸡的免疫能力，且随硒添加水平的升高效果愈好；随着试验时间的延长，添加SP的效果优于SS。

| Abstract: | Se sources(Se-enriched probiotics,SP and sodium selenite,SS)were added into basal diet at 0.2,0.5 and 1.0 mg/kg of Se.Feeding test lasted for 35 days.The results showed that the addition of either SS or SP significantly increased Se content in spleen.With an increase of the supplemental Se level,the Se content in spleen had a significant increase.Supplemental SP had a more significant action to increase Se content in spleen than SS.On days 14,supplemental Se from either SS or SP significantly promoted the T... |
