动物消化道的形态与食性、食物质量以及动物对能量的需求密切关系。本文对新疆干旱环境中生存的褐家鼠在自然环境中消化道长度及重量进行了测定,结果表明,家栖的褐家鼠只有总消化道、小肠和大肠的长度有季节差异,冬、春季高于夏、秋季。同时发现捕自阿拉山口的褐家鼠胃长度和干重有季节差异。
The animal gut morphology is closed related to food habit,food quality and energy demand.The seasonal changes in length and weight of total digestive tract and separate parts of digestive tract in Rattus norvegicus,which lived in add environment of Xinjiang were determined.The results showed that the length of whole digestive and small intestine and large intestine had significant seasonal variations,which were higher in spring and winter than in autumn and summer.We also discovered that the length and weight of stomach of the species captured in Alashankou region had significant seasonal variations.
