Testing of Drugs in Organic Feeds

The aspects of feed safety that need to be tested include feed ingredients containing toxic and harmful substances themselves, contamination during production or processing, and artificially added drugs. To promote animal growth and prevent and treat animal diseases, certain drugs are added to organic feed. If these drugs are not fully digested, they will remain in the animal's body, causing adverse effects on the quality of animal products and even consumer health.

Drug addiction is related to the quality of organic feed and directly related to the breeding effect. To ensure the quality of livestock products and the health and safety of consumers, Lifeasible offers testing services for drugs commonly found in organic feeds. Our tests are accurate and fast, providing data for quality and safety management in livestock breeding and feed production.

We offer testing methods

Methods	Details
Spectrophotometric method	It can be applied to the detection of several drugs such as penicillin and ciprofloxacin.
Microbiological method	It can be applied to the content detection of enramycin, tylosin, chlortetracycline, lincomycin, etc. This assay has the advantages of high sensitivity, low dosage, and consistent detection with the principle.
Immunoassay method	It includes the colloidal gold immunochromatographic method and enzyme-linked immunosorbent assay (ELISA). Colloidal gold immunochromatography is more suitable for a few samples or single sample detection. ELISA is more suitable for large-scale sample detection. Immunoassay has the advantages of accuracy, flexibility, rapidity, simple operation, and low instrument requirements, and can be widely used in feed drug testing.
Thin layer chromatography	This method is simple, requires less instrumentation, and is less expensive. It is suitable for rough preliminary testing and cannot be quantified.
Gas chromatography	It has high detection accuracy, low detection limit, high precision, and more sensitive detection. It can detect chloramphenicol antibiotic drugs, and the minimum detection limit is 0.005mg/kg.
High efficient capillary electrophoresis method	It has the advantages of strong selectivity, a wide range of applications, low sample and solvent consumption, high separation efficiency, and fast separation speed.
Electrochemical analysis method	It can be used for quantitative and qualitative analysis. This detection method has the advantages of convenient detection, high sensitivity, and selectivity. It can be used for the detection of sulfonamides, β-agonists, etc.
Liquid chromatography-tandem mass spectrometry	It can detect sulfonamides, benzimidazole, β-agonists and fluoroquinolones. It has the advantages of detection limit, high sensitivity, good qualitative effect, high resolution, selective analysis, etc.
High-performance liquid chromatography	It has the advantages of easy recovery, small injection volume, high sensitivity, and fast detection speed. Currently, our more commonly used detectors include fluorescence detectors, diode array detectors, UV photometric detectors, etc.

Lifeasible provides customers with services for testing the types and doses of drugs added to organic feeds, which can help you better understand the impact of drug additions on animal product quality and consumer health, and better control them.
