The invention relates to the technical field of pig raising, and particularly discloses a feed additive for improving the anti-enveloping virus capacity of pigs and a preparation method thereof.The feed additive for improving the anti-enveloping virus capacity of the pigs is prepared from, by weight, 20-40 parts of medium-chain fatty acid, 2-8 parts of chitosan oligosaccharide, 2-10 parts of plant essential oil and 2-15 parts of plant polyphenol. 15-35 parts of yeast hydrolysate, 1-3 parts of a probiotic bag and 5-20 parts of a carrier. The medium-chain fatty acid, the plant essential oil and the chitosan oligosaccharide in the feed additive for improving the anti-enveloped virus capability of the pigs can directly inhibit the growth of enveloped viruses in digestive tracts, so that the entering of virus molecules into bodies is reduced; meanwhile, the plant polyphenol, the probiotic bag and the yeast hydrolysate are used for improving the disease resistance, the self-healing ability and the immune regulation
