摘要:
<正>动物消化道的形态与食物质量、动物食性及其对能量的需求密切相关。笔者采用小型动物解剖法对不同生境的黑线姬鼠消化道各器官的长度和重量进行了测定。结果表明:黑线姬鼠消化道的胃、小肠、大肠(含盲肠)的长度和重量在不同生境中有明显变化,所测的长度和重量均表现为在林间较高而在农田较低。因此,可以认为黑线姬鼠通过延长或缩短其消化道、增加或缩短食物在其消化道内的滞留时间、增大或减小消化率等生理变化来适应环境条件的变化。
Abstract:
There exists a close relationship between morphological characteristics of animal digestive tracts with its food habit,food quality and the energy requirement of animals.The length and weight of digestive tract organs of striped field mice in different habitats were measured respectively by using the anatomic method of small animals.The results revealed that the length and weight of stomach,small intestine,and large intestine(including appendices) of striped field mice digestive tracts in different habitat were significantly varied.The length and weight measured in forest was all higher than that in field.Therefore the striped crop field mice adaptation to environmental conditions changes by means of physiological varieties such as extending or shortening the digestive tracts,increasing or reducing the time of food remained in digestive tracts,increasing or reducing digestive ratio etc.
