摘要
为了解新疆地区奶牛生产中常用抗生素类药物在牛奶中的残留情况,本试验按照新疆地区奶牛生产中抗生素类药物的使用方法及剂量进行投放,并采集牛奶样品进行检测。结果表明,青霉素钾在牛奶中的残留规律为:停药1d>5d>3d;头孢噻呋钠为:停药3d>5d>1d;链霉素为:停药1d>3d>5d;长效土霉素在牛奶中的残留量在停药1～11d一直维持在175μg/kg左右。本试验中除了长效土霉素外,其他药物的残留量均低于中国和欧共体(EEC)规定的标准残留限量。
To understand the condition of antibiotics residues for milk in cows at Xinjiang area, we have feed cows according to the method and dosage of antibiotics in cows at Xinjiang area, and collected and detected samples of milk. The results were showed as following： the residue rule of Benzylpenicillin potassium in milk was lst〉5th〉3rd withdrawal days; the residue of Ceftiofur sodium in milk was 3td〉5th〉lst withdrawal days; the residue rule of Streptomycin in milk was lst〉3rd〉5th withdrawal days; the residue of Long-acting oxytetracycline in milk was maintain 175μg/kg from 1st to llth withdrawal days. The residues of medicines used in this experiment were all lower than MRLs provided in EEC except Long-acting oxytetracyeline.
