Résumé
The phagocytic activity of peripheral blood leukocytes (PBL) in chickens orally administered sugar cane extracts (SCE) or polyphenol-rich fraction (PRF) of SCE (500 mg/kg/day) for 3 consecutive days increased significantly, when compared with that of saline-administered control chickens. Chickens orally administered SCE or PRF (500 mg/kg/day) for 3 consecutive days showed significantly higher antibody responses against sheep red blood cells and Brucella abortus than control chickens. In addition, oral administration of SCE or PRF also resulted in a significant increase in the number of IgM- and IgG-plaque forming cell responses of PBL, intestinal leukocytes and splenocytes, when compared with those of control chickens. Furthermore, delayed type hypersensitivity responses to human γ globulin significantly increased in chickens orally administered SCE or PRF, compared with those of control chickens when evaluated on the basis of net increased wattle thickness at 24, 48 and 72 h after challenge. These results suggest that PRF of SCE has an immunostimulating effect in chickens.
