乳猪体内糖类的消化和吸收研究

Study on the Digestion and Absorption of Glucide in Body of Suckling Pig

乳猪小肠内葡萄糖的分布状况既与饲料的碳水化合物种类和数量相关,也与小肠的不同部位相关,十二指肠段和空肠段分别是乳糖、淀粉类碳水化合物分解和葡萄糖吸收的主要部位。血糖浓度离肝脏越远含量越低,而与饲料中糖类含量的多少无关。

The distribution of glucose has to do with the kind and quantity of carbohydrate in feeding-stuffs as well as different position of small intestine, the duodenum and jejunum are the main places for the decomposition of lactose and polysaccharides carbohydrate, and for the absorption of glucose. The farther the blood is away from the liver the lower glucose concentration is in it but has not to do with the carbohydrate contents in feeding-stuffs.
