不同奶牛饲料中农药残留现状研究

选择精料和糠麸类、牧草及农副产物,以及蔬菜类青绿饲料3类常用奶牛饲料,分别测定饲料中敌百虫、甲胺磷、敌敌畏、马拉硫磷、辛硫磷、呋喃丹、倍硫磷和毒死蜱等8种农药残留,并对残留情况进行分析.结果表明,精料中应重点控制甲胺磷、马拉硫磷和倍硫磷的残留；补充料中,应控制玉米青贮饲料中马拉硫磷和倍硫磷的残留,以及花竿中甲胺磷、倍硫磷和敌敌畏的残留,减少紫花菜和菠菜饲喂量,各种蔬菜要控制敌敌畏、倍硫磷、辛硫磷和呋喃丹的残留.

Study on the present situation of pesticide residues in different ruminant feed

Three kinds of commonly used cow feed,such as fine fodder and bran,farm and sideline products and herbage,vegetables green fodder were selected.Eight kinds of pesticides remained on the feed:dipterex,methamidophos,dichlorvos,malathion,phoxim,furadan,fenthion,chlorpyrifos were analyzed.The results showed that,the amount of residues of methamidophos,malathion and fenthion could be mainly controlled for fine fodder;as for supplementary feed,controlling the malathion and fenthion residues for silage and methamidophos,fenthion and dichlorvos for spend rod,reducing the food amount of broccoli and spinach,as well as limiting the residues level of dichlorvos,fenthion,phoxim and furadan for all kinds of vegetables.
