In 1979, some pairs of voles (Microtus arvalis Pallas) were introduced to our laboratory from Hungary. Thereafter, they were successfully bred and increased in number, as experimental small animals for herbivorous domestic animals. They have been raised in a room and fed with pelleted feed for herbivores and chopped hay-cubes. We can change the high-fiber-containing rations from the chopped hay-cube to the alfalfa pellet that is widely available in laboratories. Regarding the breeding characteristics of the voles, the average litter size was 5.44 +/- 1.64, and the age at the first birth was 55.4 +/- 10.7 days. Some voles with white coats were found during the breeding process in our laboratory. Hematochemical characteristics of the voles were determined and the following characteristics were noted. Red blood cell counts of the voles were higher than those of other experimental animals (rat, mouse). White blood cell counts of the voles were lower than those of the other animals. The electrophoretic patterns of serum protein differed markedly from those of other experimental animals. The gamma-globulin concentrations of the voles were very low, and A/G ratios were high. Blood glucose concentrations of the voles were lower than those of the other mono-gastric experimental animals. Activities of serum enzymes (GOT, GPT, ALP) were higher than those of other experimental animals (rat, mouse, cow).
1979年，一些田鼠（草原田鼠，学名Microtus arvalis Pallas）从匈牙利被引入我们的实验室。此后，它们作为食草家畜的实验小动物被成功繁殖并数量增加。它们被饲养在一个房间里，喂食食草动物颗粒饲料和切碎的干草块。我们可以将含高纤维的日粮从切碎的干草块换成实验室中广泛可得的苜蓿颗粒。关于田鼠的繁殖特性，平均窝仔数为5.44±1.64，首次生育年龄为55.4±10.7天。在我们实验室的繁殖过程中发现了一些白色被毛的田鼠。测定了田鼠的血液生化特性，并记录了以下特征。田鼠的红细胞计数高于其他实验动物（大鼠、小鼠）。田鼠的白细胞计数低于其他动物。血清蛋白的电泳图谱与其他实验动物明显不同。田鼠的γ-球蛋白浓度非常低，A/G比值高。田鼠的血糖浓度低于其他单胃实验动物。血清酶（GOT、GPT、ALP）的活性高于其他实验动物（大鼠、小鼠、牛）。
