摘　　要：动物机体的营养代谢是一个不断变化的动态过程。血插管技术在研究营养代谢的动态过程中具有独特优势。血插管技术可用于研究不同来源或不同水平的营养素、生物活性物质、营养调控剂或药物对门静脉氨基酸、葡萄糖流量以及对机体内分泌因子、血清生化指标的动态影响效应;研究不同生理或病理条件下动物机体自身营养调控过程的机制;研究某个器官或组织对养分的吸收和代谢特点,等等。本文简要介绍了血插管技术的类型和在动物营养研究中的应用,以期为充分利用此技术加深对动物营养代谢过程及其调控机理的研究提供参考。The metabolism of nutrients in animal body is a ceaselessly changing and dynamic process. Blood vessel catheter technique has unique advantage in studying such dynamic process. The blood vessel catheter technique can be used to study the dynamic effects of nutrients with different sources or supplementary levels, bioactive compound, nutritive regulating agents or medicine on amino acids and glucose absorption rate in portal vein, blood hormones and metabolites. It can also be used to investigate the self-regulating mechanisms of animal body under different physiological or pathological conditions. Finally, it can be used to explore the characteristics of nutrients absorption and metabolism in defined organ or tissue, etc. In this paper, types of blood vessel catheters and its application in animal nutrition research were introduced simply with the purpose of providing a reference for using this technique to promote the research of animal nutrients metabolism process and its mechanism.
