Problems solved by technology

4. The phenomenon of human medicine and veterinary use still exists
5. Do not use according to the prescribed drug withdrawal period
At present, domestic methods for the simultaneous determination of multiple drug residues in livestock products and their accurate quantification are relatively lacking, so it is urgent to establish a detection technology for the simultaneous determination of multiple drug residues

Embodiment Construction

[0078] The feed is compound feed, concentrated feed and premixed feed.

[0079] The 110 kinds of antibacterial drugs are:

[0080] (a), macrolides (11 species): tylosin, tilmicosin, tiamulin, azithromycin, clarithromycin, erythromycin, roxithromycin, natamycin, bamboo Taomycin, spiramycin I, kitasamycin;

[0081] (b), fluoroquinolones (17 kinds): enrofloxacin, ciprofloxacin, sarafloxacin, difloxacin, nafloxacin, sparfloxacin, norfloxacin, oxolinic acid, Pefloxacin, marbofloxacin, orbifloxacin, flumequine, nalidixic acid, cinoxacin, lomefloxacin, ofloxacin, fleroxacin;

[0082] (c), sulfonamides (20 species): sulfamethoxine, sulfamethoxazole, sulfamethoxine, sulfaquinoxaline, sulfamethazine, sulfachloropyridazine, sulfapyridine, sulfamethoxine Azole, sulfamethiadiazole, sulfamethoxazole, sulfamethoxazine, sulfachlorpyrazine, sulfamethoxine, sulfadiazine, sulfamethazine, sulfisoxazole, benzosulfonamide, sulfonamides , sulfamethoxine, sulfathiazole;

[0083] (d), quinoxaline...

Abstract

The invention discloses a screening method for 110 types of medicines in feed, which specifically includes the following steps: preparation of standard work solution, pre-analysis treatment of sample to be assayed, creation of database and qualitative analysis. By utilizing the high-sensitivity MSMS (Tandem Mass Spectrometry) function of a liquid chromatography-tandem quadrupole time-of-flight mass spectrometer, the screening method can accurately determine parent ions and daughter ions in medicines and rapidly determine added medicine ingredients, moreover, an assay method for a variety of antibacterial medicines in feed is also established, and for a variety of added antibacterial medicines in the feed industry in China, the screening method has a highly efficient, accurate and precise assay measure, and is at the advanced level in china at present. The screening method established by the invention greatly solves the phenomenon of arbitrary addition in the feed industry, the more precise and accurate assay method is perfected for the inspection department, more time is saved, most of experimental consumables are saved, and the invention makes an immeasurable contribution to food safety and human healthy life.

Description

technical field [0001] The invention belongs to the technical field of feed detection, and in particular relates to a screening method for 110 kinds of medicines in feed. Background technique [0002] Since Moore et al. (1946) reported for the first time that adding antibacterial drugs to the feed can significantly increase the daily gain of broilers. Since then, more than 60 kinds of antibacterial drugs have been used in animal husbandry, playing an important role in the prevention and control of animal diseases, improving feed utilization, and promoting the growth of livestock and poultry. However, with the extensive use of antibacterial drugs, especially the unscientific abuse, problems such as bacterial drug resistance and drug residues have become increasingly prominent, which has attracted great attention from governments and industry insiders around the world. In 2006, the European Union completely banned the application of antimicrobial drug feed additives. my coun...
