反刍动物饲料产品和动物源性饲料产品中牛羊源成分检测

[目的]检测反刍动物饲料和动物源性饲料中牛羊源成分。[方法]利用实时荧光定量PCR技术对反刍动物饲料产品（预混料、精料补充料、全价配合料等）和动物源性饲料产品（鱼粉、禽肉粉、猪肉粉、羽毛粉等）共计131批样品进行了牛羊源成分检测。[结果]所有样品中均未检出牛羊源性成分。[结论]该次抽检的反刍动物饲料产品和动物源性饲料产品中暂无牛羊源成分污染，但仍应加强对反刍动物饲料和动物源性饲料中牛羊源成分的监测。

Detection of Cattle and Sheep-derived Components in Feed Products of Ruminants and Animal-derived Feed

Objective] The research aimed to detect cattle and sheep-derived components in the feed of ruminants and animal-derived feed. [Method]The cattle and sheep-derived components in 131 batches of the feed products （premix, concentrate supplement, complete feed, etc.） of ruminants and animal-derived feed （fish meal,poultry meat powder, pork powder, feather meal, etc.） were detected by real-time fluorescence qualitative PCR. [Result] No cattle and sheep-derived component was detected in all samples. [Conclusion] No cattle and sheep-derived component was found in the detected feed products of ruminants and animal-derived feed. The monitoring of cattle and sheep-derived components should still be strengthened.
