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.
