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).

Effects of Green Tea Powder on Immunological Function of Aged Canines
摘  要：
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) reached the highest,increased significantly(P0.05) up to 47.83%.Although lower adding green tea powder(1 000 mg/kg) reduced serum lysozyme activity in the aged canine,but not significantly(P0.05),and 2 000 mg/kg and 4 000 mg/kg groups serum lysozyme activity in aged canine were increased obviously(P0.01).Compared with control the contents of lysozyme in the 2 and 3 treatments increased 32.76% and 19.39% respectively.At the same time,that addition of green tea powder,the total protein(TP) in blood were slightly higher than those in control(P0.05).When the levels of green tea power increased,the contents of globulin increased.Treatment 3(4 000 mg/kg) were higher than those in the control group(P0.05).
