The invention discloses an acidizing agent for feed and a preparation method of the acidizing agent. The acidizing agent comprises, by weight, 10-60 parts of
phosphate acid and
phosphate, 1-40 parts of
acetic acid and acetate, 20-30 parts of
citric acid and 10-40 parts of a carrier. The
phosphate acid and phosphate serve as main providers of acid, and the
acetic acid and acetate serve as nutritional enhancers; through the interaction between the raw materials, the reaction between the acidizing agent and alkaline material in the feed is avoided, the
utilization rate of the feed is effectivelyimproved,
diarrhea of animals is reduced, the
digestion of the feed in poultry
crop is promoted, and meanwhile,
pathogenic microorganism is inhibited, and the production efficiency of farms is improved; the raw materials of the product are non-toxic, the
biosafety is high, no toxic or side effects are caused to the
animal body, and all the raw materials conform to the feed hygienic standard; the preparation method is simple, the raw materials can be mixed by premixing and are added to the feed according to a certain proportion by evenly mixing, less adding amount is achieved, the raw materialsource is large, the price is low, and easy industrial production and good application prospect are achieved.
