摘　　要：[Objective] This study aimed to investigate effects of Echinacea compound on the immune function of weaned piglets. [Method] Eighty Duroc x Landrace x Yorkshire crossbred piglets were randomly divided into four groups： control group （drug-free group）, 1.5% close group, 1.0% dose group and 0.5% dose group. Blood samples of piglets were collected at 20, 35, 50, 60, 70 and 80 days old, respective- ly, to determine neutrophil leukocyte percentage in peripheral blood, lymphocyte trapsformation rate and the levels of antibodies against classical swine fever, porcine reproductive and respiratory syndrome disorder. [Result] Applying a certain dose of Echinacea compound could significantly increase neutrophil leukocyte per- centage in peripheral blood and lymphocyte transformation rate （P〈0.05）, and ex- tremely significantly improve the levels of antibodies against classical swine fever, porcine reproductive and respiratory syndrome disorder （P〈0.01）. [Conclusion] Echi- nacea compound has played a certain role in promoting nonspecific and specific im- mune function of piglets.[目的]研究紫锥菊复方对仔猪免疫机能的影响。[方法]试验将三元杂交仔猪随机分为4组,对照组(无药组)、试验Ⅰ、Ⅱ、Ⅲ组(紫锥菊复方1.5%组、1.0%组、0.5%组)。并分别于20、35、50、60、70、80日龄采血检测仔猪外周血嗜中性白细胞百分数、淋巴细胞转化率、猪瘟、猪呼吸繁殖障碍综合征抗体水平等免疫指标。[结果]应用一定剂量的紫锥菊复方能显著提高仔猪外周血嗜中性白细胞百分数和淋巴细胞转化率(P<0.05),极显著提高猪瘟、猪呼吸繁殖障碍综合征疫苗的抗体水平(P<0.01)。[结论]紫锥菊复方对仔猪的免疫功能具有一定的促进作用。
