The invention mainly relates to the field of animal husbandry and veterinary medicines and discloses a method for rapidly detecting veterinary antibiotics. The method comprises the following steps: taking samples, feeding the samples, culturing the samples, and performing result judgment. A bacterial liquid is directly prepared after the sample is taken, then the activity of bacteria in a diseasematerial is maintained, the culture time is shortened to 16 hours, effective treatment on sick livestock is accelerated, and the economic loss of farmers is reduced; the method is simple and convenient, no professional skill or large-size equipment is needed, heat-preservation culture is implemented after the sample is taken, and the testing time is shortened; if growth of pathogenic bacteria cannot be inhibited by antibiotics in a testing tube, the testing tube turns into red from clear colorless, the conventional operation that the size of an inhibition zone is observed is replaced by observation on color change, relatively good sensitivity is achieved, the operation is simple and visible, antibiotics can be accurately selected by farmers, appropriate medicines can be administrated for diseases accurately, diseases can be prevented and treated rapidly, and the economic loss of the farmers is reduced; complete types of antibiotics can be put into the testing tube, pathogenic bacteriaof livestock can be detected, and thus the method is wide in application range.
