The valnemulin artificial antigen is a compound as shown in a formula I, wherein n denotes a natural number from 1 to 25; and K denotes carrier protein. When the artificial antigen is used to immunize a New Zealand white rabbit, an antibody with specific reaction to valnemulin can be obtained. According to ELISA experiments, the titer of the obtained antiserum reaches 1:102400. The invention provides a wide application and development space for the development of detection reagent used in the enzyme-linked immunoassay method of the valnemulin and the preparation of the enzyme-linked immunoassay reagent kit of the valnemulin. When the antibody obtained by using the artificial antigen is used for the detection of the valnemulin, the operation is simple and convenient, the specificity is good and the accuracy is high. The antibody can be used for the rapid and high-efficiency screening of the valnemulin in animal-based foods and a technical foundation is laid for the rapid detection of the valnemulin. The formula I is as shown is the accompanying drawing.
