Meat chicken feed and preparation method thereof

The invention discloses a meat chicken feed. The formula of the feed consists of corn, enzymolysis bean pulp, corn albumen powder, dry corn distilled grain, edible oil and fat, calcium hydrogen phosphate, salt, composite vitamin, composite trace element, composite amino acid and composite enzyme preparation serving as main components. The feed is prepared by the following steps of: crushing the corn, the corn albumen powder, the dry corn distilled grain and the prepared enzymolysis bean pulp until granularity reaches 0.5 to 0.8 millimeters, mixing the components uniformly, adding the rest feed components, and mixing all the components uniformly to obtain the product. Aiming at the characteristics of incomplete digestive physiology and the like of the meat chicken, the enzymolysis bean pulp, a bacillus subtilis preparation and an enzyme preparation are added in the formula of the feed, so that the survival rate and the production performance of the chicken are improved, the digestive utilization efficiency of organic substances and mineral substances is improved at the same time, the emission of nitrogen and phosphorus in the manure is reduced, and pollution of the nitrogen and the phosphorus in the chicken manure to the soil and the water is effectively controlled.
