根田鼠基础代谢率对单宁酸反应的格局

RESPONSIVE PATTERNS OF ROOT VOLES TO TANNIC ACID

采用Kalabukhov skvortsov封闭式流体压力计测定根田鼠基础代谢率对食物单宁酸的反应格局。在食物蛋白质为 10 %条件下 ,摄入 3%单宁酸食物的根田鼠在第 5天、第 10天和2 0天的基础代谢率分别较第 0天增高 10 94 %、 2 3 82 %及 2 3 54% ;摄入 6%单宁酸食物的根田鼠在第 5天、第 10天和第 2 0天的基础代谢率分别较第 0天增高 18 67%、 2 9 0 7%及2 7 71%、当食物蛋白质为 2 0 %时 ,摄入 3%单宁酸食物的根田鼠在第 5天、第 10天和 2 0天的基础代谢率分别较第 0天增高 6 67%、 10 63%及 11 2 1% ;摄入 6%单宁酸食物的根田鼠在第 5天、第 10天和 2 0天的基础代谢率分别较第 0天增高 9 0 1%、 14 50 %及 16 0 9%。说明 ,食物单宁酸能显著地增加根田鼠的基础代谢率 ,充分检验了单宁酸使植食性小哺乳动物基础代谢率增高的假设。

BMR of the root voles fed 3% tannic acid diet at day 5,day 10 and day 20 were higher than that of the voles at day 0 by 10.94%, 23.82% and 23.54%, respectively; and BMR of root voles fed 6% tannic acid diet at day 5,day 10 and day 20 were higher than that of the voles at day 0 by 18.67%, 29.07% and 27.71% on the 10% level protein diet, respectively. BMR of the root voles fed 3% tannic acid diet at day 5,day 10 and day 20 were higher than that of the voles at day 0 by 6.67%, 10.63% and 11.214% , respectively; and BMR of root voles fed 6% tannic acid diet at day 5,day 10 and day 20 were higher than that of the voles at day 0 by 9.01%, 14.50% and 16.09% on the 10% level protein diet, respectively. These primary results indicated that dietary tannic acid could significantly increased BMR of root voles (Microtus oeconomus), and strongly supported the hypotheses that tannic acid could significantly increased BMR of small mammalian herbivores.
