摘要: 在AA肉鸡的饮水中分别加入0%、0.2%和0.4%的茶多糖,研究其对肉仔鸡免疫功能和抗氧化能力的影响。试验结果表明,茶多糖能显著促进肉仔鸡胸腺的生长发育(P<0.05),可以明显升高血清中免疫球蛋白IgG的含量(P<0.05),提高T-淋巴细胞数和淋巴细胞转化率(P<0.05),增强白细胞吞噬功能(P<0.05),但对法氏囊的生长发育没有明显作用;同时,茶多糖能显著提高肉仔鸡血清中SOD活力(P<0.05)、GSH-Px活力(P<0.05)和CAT活力(P<0.05),并能明显降低血清中MDA含量(P<0.05)。

Abstract: To study the effect of tea polysaccharide on immune function and antioxidative activity in broilers, 0%、0.2%、0.4% of tea polysaccharide were added into the drinking water for broilers respectively. Results showed that thymus index and serum IgG levels of broilers were increased obviously by TP(P<0.05), furthermore lymphocyte transformation rate, macrophage activity, percentage of T cell numbers Serum SOD, GSH-Px and CAT activities in broilers were increased obviously by TP at same time(P<0.05)but not to index of fabricius bursa of broilers. Serum MDA levels of broilers were declined obviously by TP(P<0.05).

Key words: Tea polysaccharide, Broiler, Immune function, Antioxidation activity
