摘　　要：200只1日龄健康三黄鸡,随机分为空白对照组、低剂量组、中剂量组、高剂量组4组,空白对照组皮下注射灭菌生理盐水;低剂量组、中剂量组、高剂量组分别按2.5、5.0、7.5 mg/只皮下注射黄芪多糖注射液,分别于第2、3、4、5、6周龄检测红细胞数量、C3b花环率和IC花环率,结果表明,黄芪多糖可显著提高三黄鸡红细胞数量和红细胞C3b花环率,同时显著降低红细胞IC花环率。因此,黄芪多糖可显著提高三黄鸡的红细胞免疫功能。200 1-day-old broilers were divided into four groups（CK,Low Dose ,Median Dose ,High Dose）randomly. The broilers of group CK were injected subcutaneously with starile saline and the other groups with 2.5 mg ,5,0 mg and 7.5 mg astragalus polysaccharides （APS）. The numbers of erythrocytes, E-C3bR rate and E-IC rate were detected on the 2nd, 3th, 4th, 5th and 6th weekend. The results indicated that the numbers of erythrocytes and E-C3bR rate of broiler were increased, but the number of E-IC rate was decreased significantly. Therefore, APS can improve the immune function of erythrocytes significantly in broilers.
