摘　　要：试验研究了不同剂量水平绿茶粉对老年犬免疫功能的影响。选取10岁初始体重34.5~37.5kg的拉布拉多72头,随机分为4组,分别饲喂添加0、1000、2000、4000mg/kg绿茶粉饲料,每组3个重复,每个重复6头犬,试验进行9周。结果显示,添加量为2000mg/kg时,T淋巴细胞转化率达到最高,与对照组相比,提高了47.83%(P<0.05)。低添加量绿茶粉(1000mg/kg)降低了老年犬血清中溶菌酶的含量,差异不显著(P>0.05),但2000mg/kg和4000mg/kg绿茶粉处理组溶菌酶含量分别提高了32.76%(P<0.01)和19.39%(P<0.01)。同时提高了血清中总蛋白含量(P>0.05),随着绿茶粉添加量的增加,球蛋白含量有所增加,4000mg/kg组球蛋白含量高于对照组,但差异不显著(P>0.05)。The aim of experiment was to investigate the effects of different levels of green tea powder on immunological function in aged canines.Seventy two ten year-old aged canines with an average body weight of 34.5~37.5 kg were randomly allocated into 4 groups with 3 replicates of 6 canines,four diets containing green tea powder(0,1 000,2 000,4 000 mg/kg) were given to feed the canine for 9 weeks.The results indicated that containing green tea powder(2 000 mg/kg) group T Lymphocyte Transformation Rate(LTT) reache...
