摘要
根据鸡球虫病的特点,研究不同浓度水平的茶多酚(tea polyphenol)对未孢子化以及完全孢子化Emeria tenella球虫卵囊的作用效果;并通过在基础日粮中添加0.02%、0.04%和0.06%不同浓度水平茶多酚的肉鸡饲养试验,初步研究茶多酚抗E.tenella球虫的作用机制。结果表明,茶多酚具有明显抑制未孢子化E.tenella球虫卵囊成熟的作用,且茶多酚浓度越高,抑制效果越好;茶多酚对孢子化卵囊具有一定杀灭作用,并可提高肉鸡免疫器官指数,增强其免疫功能和抗炎作用,其中以添加0.04%茶多酚的试验效果较好。
According to the characteristics of coccidiosis in chickens, the effect of different levels of tea polyphenol（TP）on the unsporulated and sporulated Eimeria tenella oogonium was investiga- ted. Through a broiler feeding trial, 0. 02%, 0. 04% and 0. 06% levels of tea polyphenol （TP） were supplemented in the diet to investigate the anti- coccidiosis effect. The results showed that TP could significantly inhibit the maturing of unsporulated oogonium of Eimeria tenella, and the higher concentration, the better inhibiting effect. TP could kill the sporulated oogonium,increase the immune organ index and immune function of broilers, and had anti-inflammatory effects. 0.04% TP in the diet is considerable.
