The invention relates to the technical field of
animal feed processing, and particularly discloses a pig feed and a
processing method thereof.The pig feed comprises a cereal
raw material, a
protein raw material, an energy supplementing
raw material, a mineral raw material, a
vitamin and microelement premix and two-phase fermented corn particles, wherein the two-phase fermented corn granules are composed of a delayed release granule core containing fermented corn, lipid, a pH sensitive
polymer coating layer and a quick release outer layer containing fermented corn, so that a part of a
fermentation product is quickly released in the gastric segment, and the other part of the
fermentation product is delayed to be released in the rear segment of the
small intestine, especially in the
ileum region, so as to realize targeted regulation and control on
ileum flora. Compared with daily ration only adopting common fermented corn, the
processing method has the advantages that the growth performance is kept, the ratio of
ileum lactic acid bacteria to
escherichia coli can be more effectively increased, the intestinal health is improved, the emission of
ammonia gas and
hydrogen sulfide in excrement is further reduced, and the processing method has remarkable
nutrition regulation and control and environment-friendly effects.
