Abstract: 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 day5, 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.

摘要: 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20天的基础代谢率分别较第0 天增高10.94、23.82%及23.54%;摄入6%单宁酸食物的根田鼠在第5 天、第10 天和第20天的基础代谢率分别较第0 天增高18.67%、29.07%及27.71%、当食物蛋白质为20%时,摄入3%单宁酸食物的根田鼠在第5 天、第10 天和20 天的基础代谢率分别较第0天增高6.67%、10.63%4及11.21%;摄入6% 宁酸食物的根田鼠在第5 天、第10 天和20 天的基础代谢率分别较第0 天增高9.01%、14.50%及16.09%。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。
