Bactericidal acidifier for animal drinking water and feed

The invention belongs to the technical field of feed additives, and particularly discloses a bactericidal acidifier for animal drinking water and feed. The bactericidal acidifier comprises the following components in parts by weight: 10-30 parts of formic acid, 10-40 parts of ammonium formate, lactic acid or citric acid and 30-80 parts of carrier, wherein the molar ratio of formic acid to ammoniumformate is 1: 0.5-1.5. The bactericidal acidifier for animal drinking water and feed has a good bactericidal effect, can effectively clean and improve drinking water and feed, reduce the incidence ofanimal diarrhea, promote healthy growth of animals, inhibit and kill pathogenic microorganisms and improve the production efficiency of farms, and can be added into drinking water and feed in proportion for uniform mixing when in use. The bactericidal acidifier has the advantages of simple process, low addition amount, huge raw material source, low price, low cost, easiness in industrial production and good application pr
