The invention discloses a traditional Chinese medicine composition capable of improving the escargot immunity. The traditional Chinese medicine composition is characterized by being prepared from, by weight, 4-8 parts of radix astragali, 6-10 parts of Chinese yams, 3-5 parts of kudzu vine roots, 6-10 parts of poria cocos and 3-5 parts of radix ophiopogonis, all the traditional Chinese medicine raw materials are processed through coarse grinding and then processed through superfine grinding to be prepared into powder with the particle size smaller than 10 micrometers, and the powder is fully mixed evenly and then subpackaged. According to the traditional Chinese medicine composition, by adopting a superfine grinding technology, the medicine material components are fully released, and the traditional Chinese medicine utilization rate is improved; by adopting a micro-adding technology, 1 kg of the traditional Chinese medicine composition is added in every ton of feed, the using amount is small, the cost is low, and the using effect is good; by using the traditional Chinese medicine composition for a long time, the escargot organism immunity can be significantly improved, and the feed conversion rate is increased.
