养殖动物兽药残留控制检体的选择（英文）

Selection of Test Samples for Monitoring Veterinary Drug Residue in Bred Animals

[目的]比较分析违禁药物西马特罗在猪毛、猪尿、猪肉中的代谢情况,选择养殖动物兽药残留控制的检体。[方法]通过给药试验,设置3个不同浓度添加量的处理,分别以猪尿、猪毛、猪肉为监控目标,了解不同的饲养阶段西马特罗的残留情况。[结果]饲喂药物阶段,药物在尿液中的浓度最高,适合生产企业前沿的快检控制,药物在毛发中具有累积作用,代谢缓慢,可作为违禁药物监控追溯的检测靶体,是药物残留活体监控的理想目标,肉品检测是药物残留限量符合性的直接证据。[结论]为畜牧养殖药物监控手段提供理论依据。

[Objective] This study aimed to compare the residue situation of cimaterol,a kind of forbidden veterinary drug in hair, urine and flesh of pig, so as to provide theoretical basis for monitoring veterinary drug residue in bred animals. [Method]Total three different concentrations of cimaterol were administered to pigs, and the residue amounts of cimaterol in pig hair, urine and flesh were monitored at different raising stage. [Result] During the administration period, the residue amount of cimaterol was highest in urine, so urine is the suitable sample for rapid detection of cimaterol in manufacturing enterprises. Cimaterol could be accumulated in pig hair,where cimaterol was metabolized slowly. Thus, pig hair can be used as the test sample for tracing illegal use of veterinary drugs and for vivo detection. Flesh can be used as test sample for direct judgment whether cimaterol residue exceeds the relevant standard. [Conclusion] This study will provide certain theoretical basis for drug monitor in animal husbandry.
