极田鼠基础代谢率对单宁酸反应的格局

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、10天和20天的基础代谢率分别较第0天增高10．94％、20．82％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天的基础代率分别较第0天增高6．67％、10．63％及11．21％；摄入6％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9．01％、14．50％及16．09％。说明，食物单宁酸能显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。

RESPONSIVE PATTERNS OF ROOT VOLES TO TANNIC ACID

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
