摘　　要：目的　探讨酵母多糖对仔鸡免疫系统的影响。方法　在仔鸡常规育雏及育肥期间，用酵母多糖灌胃（20 mg/kg）或肌注（2 mg/kg），并观察其对仔鸡脾脏、腔上囊及T淋巴细胞的作用。结果 与对照组比较，无论是灌胃或是肌注，酵母多糖对仔鸡脾脏、腔上囊和T淋巴细胞都可产生明显影响：脾脏重量（mg/10 g体重）增加：淋巴细胞数量(万/cm3)上升，对MTT的吸收能力增强；腔上囊皱襞增生。结论 酵母多糖是一种既可促进鸡的细胞免疫能力，又可提高其体液免疫应答水平的免疫增强剂，因此将其开发应于家禽（畜）养殖业是有前途的。Objective To explore the influence of yeast polysaccharides (YPS)on immune system of chicken. Methods YPS were given per stomach(20mg/kg)or intramuscularly (2mg/kg) in order to study the effect on spleen,Fabricicus' bursa and T-lymphocyte of chicken. Results The results showed that the gains in weight of spleen,bursa folds and the number of T-lymphocyte were higher in study groups than in control group. Conclusion YPS can improve immunologic function of chicken, showing its potential application in poultry breeding.
