为研究黄芪茎叶超微粉对雏鸡非特异性免疫功能的影响,将200只1日龄健康雏鸡随机分为5组,每组40只鸡:Ⅰ组为不用药对照组,Ⅱ组为0.5%黄芪根普通粉对照组,Ⅲ~Ⅴ组分别为黄芪茎叶超微粉的0.5%、1.0%、1.5%3个剂量组。在21、28、35、42和49日龄时检测体重、免疫器官指数和外周血白细胞总数,在49日龄时测定碳粒廓清率。结果显示,1.0%、1.5%黄芪茎叶超微粉能显著提高雏鸡的外周血白细胞总数(P<0.05或P<0.01);黄芪根普通粉和黄芪茎叶超微粉均可显著提高鸡的体重和胸腺指数(P<0.05或P<0.01),1.5%黄芪茎叶超微粉的作用效果与黄芪根普通粉的作用相当;黄芪根普通粉和1.0%黄芪茎叶超微粉可以极显著提高雏鸡的碳粒廓清率(P<0.01),两者作用相当。研究表明,黄芪茎叶超微粉能够显著提高雏鸡的非特异性免疫功能。
To study the effect of astragalus membranaceus superfine powder on non-specific immune function of chickens, 200 healthy 1-day-old chickens were randomly divided into 5 groups with 40 chickens in each group: group Ⅰ was treated with no medication, group Ⅱ was treated with 0.5% Root ordinary powder control group, Ⅲ ~ Ⅴ group were 0.5%, 1.0%, 1.5% of astragalustemon ultrafine powder three dose groups. At 21, 28, 35, 42 and 49 days of age, body weight, immune organ index, and total number of peripheral white blood cells were measured, and the carbon clearance rate was measured at 49 days of age. The results showed that 1.0%, 1.5% Astragalus stem and leaves superfine powder can significantly increase the total number of peripheral white blood cells (P <0.05 or P <0.01); Astragalus root and Astragalus stem and leaves superfine powder can significantly increase the body weight and Thymus index (P <0.05 or P <0.01), 1.5% Astragalus stem and leaves superfine powder effect and Astragalus root ordinary powder effect; Astragalus root ordinary powder and 1.0% Astragalus stem and leaf superfine powder can significantly improve the chicken’s carbon Particle clearance rate (P <0.01), the role of the two quite. Studies have shown that Astragalus stem and leaves superfine powder can significantly improve the non-specific immune function of chickens.
