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.
