The invention belongs to the technical field of feed processing, and discloses a nonreactive feed for improving the pork quality. The feed is prepared from, by weight, 530-580 parts of corn, 160-200 parts of soybean meal, 60-70 parts of bran, 30-32 parts of wheat middlings, 10-15 parts of calcium hydrophosphate, 10-14 parts of a compound microbial ecological agent, 10-12 parts of calcium carbonate, 8-10 parts of soybean oil, 5-7 parts of phytase, 4-7 parts of choline chloride, 4-6 parts of sodium chloride, 4-6 parts of L-lysine hydrochloride, 3-5 parts of DL-methionine, 3-5 parts of piglet premix, 2-5 parts of ferrous bisglycinate, 2-5 parts of a selenium yeast, 2-4 parts of amino acid manganese chelate, 1-3 parts of L-threonine, 1-3 parts of L-tryptophan, 1-3 parts of feed grade magnesiumoxide, 1-3 parts of vitamin E and 1-3 parts of vitamin C. According to the feed formula, intestinal harmful bacteria can be inhibited, nonreactive feeding of live pigs is achieved, not only can the purpose that no antibiotic residues exit in pork be guaranteed, but also the eating quality of the pork can be improved.
