摘要
【目的】本研究明确了四川省典型畜禽养殖场沼液中抗生素的残留种类及含量。【方法】选取省内13个典型县的26家畜禽养殖场,以调查问卷的形式,结合液相色谱串联质谱法抽样检测的方式进行分析。【结果】26份抽检沼液的抗生素样本检出率高达84.6%,特别是农业部已经禁止兽用的磺胺间甲氧嘧啶检出率达73.08%、氧氟沙星检出率50%、诺氟沙星检出率7.69%。本次抽检的26份沼液样中4种磺胺类、2种四环素类、3种喹诺酮类抗生素检出率较高,特别是原农业部禁止兽用的磺胺间甲氧嘧啶、氧氟沙星、诺氟沙星也在部分样品中检出。【结论】建议养殖场调整饲料配方,并严格遵守兽药使用的各种法律法规,尽快停用相关违禁药物。
【Objective】The purpose of this study was to clarify the residual types and contents of antibiotics in biogas slurry of typical livestock and poultry farms in Sichuan province.【Method】Analysis of 26 selected livestock and poultry farms in 13 typical counties of this province were conducted a questionnaire survey,combined with sampling detection by liquid chromatography tandem mass spectrometry.【Result】The detection rate of total tested antibiotics of the 26 biogas slurry samples was up to 84.6%,especially the rates of the sulfa-pyrimidine,ofloxacin and norfloxacin,which have been banned for animal use by the Ministry of Agriculture of China in 2017,were 73.08%,50%and 7.69%,respectively.In the 26 tested samples,four types of sulfonamides,two tetracyclines and three quinolones antibiotics showed high detection rates.Especially sulfamethoxazole,ofloxacin and norfloxacin which were banned by the former Ministry of Agriculture for veterinary use were also detected in some samples.【Conclusion】It is suggested that the feed formulation should be adjusted in the farms,and all kinds of laws and regulations on veterinary drug use should be strictly abided by,so as to stop the use of prohibited drugs as soon as possible.
