Summary:The invention relates to the field of veterinary drugs, in particular to a tilmicosin slow-release enteric agent and a preparation method thereof. The tilmicosin slow-release enteric agent is preparedfrom, by weight, 20-25 parts of tilmicosin, 1-3 parts of povidone and 65-80 parts of carrier; the carrier is selected from one or more of flour, corn starch, microcrystalline cellulose, sodium carboxymethyl starch and hydroxypropyl methyl cellulose. Accordingly, by improving the formula and preparation technology of the tilmicosin slow-release enteric agent, the tilmicosin slow-release enteric agent is prepared by adopting an extrusion-spheronization technology, the coating rate is larger than 99.99%, the bitter taste of tilmicosin can almost be covered completely, gastric acid reaching the stomach does not overflow, the purpose that the enteric agent is released at the intestinal tract after being eaten by a pig, the dwell time of the drug at the intestinal tract is prolonged, the slow-release effect is achieved
