The methods for the detection and analysis of veterinary drugs in feed in recent years were reviewed. A brief introduction on the relative laws and regulations regarding the usage of forage and medicine, as well as the advantages of using veterinary drugs and the harm of illegal uses of unsafe drugs in feed were summarized. Emphasis was laid on pretreatment technology and detection technology of feed matrices, including sample extraction and separation as well as purification and different detection methods, being in use for the determination of drugs. It is provided to illustrate common trends and method variability. The advantages and disadvantages of different detection techniques, as well as the application of different detection techniques in the detection of veterinary drugs were analyzed. Finally, the possibilities of novel analytical approaches were discussed. Due to the variety of the veterinary drug and the complex feed matrix, there are many differences in the detection methods of veterinary drugs. However, the exact, fast and high-throughput detection methods are relatively few. It is necessary to optimize the pretreatment technology, shorten pre-processing time and improve detection efficiency of veterinary drug detection, and intensify research and development of high-sensitivity and accuracy detection technology to provide a reliable basis for better supervision and regulation of the use of veterinary drugs in feed.
