摘  要：
选取10岁初始体重为34.5～37.5 kg的拉布拉多犬72条,随机分为4组,每组3个重复,每个重复6条,分别饲喂添加0,1 000,2 000和4 000 mg/kg绿茶粉饲料,以研究不同水平绿茶粉对老年犬血清生化指标和抗氧化指标的影响,试验进行60 d。结果表明:随着绿茶粉添加量的增加,谷丙转氨酶、谷草转氨酶、总胆红素逐渐下降,除1 000 mg/kg组外各试验组均显著低于对照组;随着绿茶粉从1 000 mg/kg提高到4000 mg/kg,血清中甘油三酯、胆固醇都显著低于对照组(P<0.05)。尿酸、尿素氮、葡萄糖、高密度脂蛋白和低密度脂蛋白差异不显著(P>0.05)。同时,绿茶粉能显著提高老年犬血清中超氧化物歧化酶(SOD)活力(P<0.05)、谷胱甘肽过氧化物酶(GSH-Px)活力(P<0.01),并能明显降低血清中丙二醛(MDA)含量(P<0.05)。结果提示,添加2 000 mg/kg绿茶粉对老年犬有很好的保健作用。

摘  要：
The aim of experiment was to investigate the effect of different levels of green tea powers on blood biochemical indices and antioxdative activities in aged canines.A total of 72 canines of ten year-old with body weights of 34.5～37.5 kg were randomly allocated into 4 groups with 3 replicates of 6 canines,four diets containing green tea power(0,1 000,2 000,4 000 mg/kg) were given to feed the canine for 9 weeks.The results indicated that serum levels of AST,ALT and TBIL gradually decreased as increased green tea power added,the decreased levels were significant(P<0.01) except the group of 1 000 mg/kg.When green tea power increased from 1 000 to 4 000 mg/kg,serum TG and CHO significantly lower than those in control(P<0.05),while,serum UA,BUN,GLU,HDL and LDL were not influenced(P>0.05).In addition,serum SOD,GSH-PX activities in numbers of aged canine were increased obviously(P<0.05),serum MDA levels were decreased obviously(P<0.05) by green tea power.In conclusions,there are certain health care function by adding 2 000 mg/kg green tea power in aged canine.
