摘要
稳定性同位素具有衰变期长,不受试验时间限制,灵敏度高、受外界环境影响小等特点。稳定同位素在动物科学中的应用主要是通过以下2种方式:在稳定同位素示踪方法(stable isotope tracer methods,SITM)中作为示踪剂、利用动物体内的稳定性同位素对动物进行稳定同位素比率分析(stable isotope ratio analysis,SIRA)。本文概述了我国动物组织器官稳定同位素在研究动物食性和营养级的确立、动物性食品溯源、动物产品品质鉴定、动物医学和动物营养等方向的应用进展,以及在研究中常用的稳定同位素碳、氮、氢、氧等元素及其在动物组织器官中的分布特点;指出了稳定同位素在动物食品溯源研究中尚存的一些问题和不足;并对其未来在动物组织器官利用方面的发展趋势进行了展望。
The stable isotopes have many features,like with a long period of stable isotopes decay,without experimental time limit,high sensitivity,the external environment impact and so on,The applications of stable isotope in animal scientific research are primarily in two ways： stable isotope tracer methods（ SITM） as a tracer; analysis the stable isotopes in animals by the stable isotope ratio analysis（ SIRA）. This paper provides an overview of research progress of stable isotope in animal tissues and organs on studies of animal feeding and the establishment of trophic level,animal food traceability,animal product quality identification,animal nutrition and medicine and so on,as well as the amount and distribution of commonly used stable isotopes of carbon,nitrogen,hydrogen,oxygen and other elements in animal tissues and organs. This paper has pointed out some problems of stable isotope studies in animal food traceability and inadequate surviving,and the aspects of stable isotope using in animal tissues and organs in the future has been discussed.
