Compound feed for piglets and preparation method and application thereof

Abstract

The invention discloses compound feed for piglets and a preparation method and application thereof and belongs to the technical field of piglet feed processing. The compound feed for the piglets comprises, by mass, 60-70 parts of corn, 10-20 parts of bean pulp, 5-10 parts of extruded soybeans, 2-6 parts of steam fish meal, 1-5 parts of lactose, 1-4 parts of rice bran meal, 0.2-1.2 parts of wheat bran, 0.5-1 part of beet pulp, 0.3-1 part of rice hull powder, 0.03-0.09 part of multi-vitamin, 0.2-0.6 part of acidifying agents, 1.7-4 parts of phytase, 0.2-0.6 part of L-lysine, 0.01-0.05 part of DL-methionine, 0.01-1 part of mould inhibitors, 0.1-0.15 part of zinc oxide, 0.2-0.6 part of compound microelement, 0.5-2 parts of saccharomycete agents and the like. According to the compound feed for the piglets, the protein level of the piglets can be improved, and the digestibility and the immunity of the piglets are improved; and meanwhile, the effective digestibility of the piglets on nutrient substances such as zinc, phosphorus, the microelements, protein and amylum is improved, and pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of piglet feed processing, and in particular relates to a piglet compound feed and its preparation method and application. Background technique [0002] Good growth performance of piglets is one of the keys to modern pig production. As the early weaning age of piglets is getting earlier, it becomes more and more difficult for the underdeveloped piglet intestines to adapt to high-nutrition, high-energy solid feed, resulting in increased diarrhea and mortality of piglets during production. Promoting the early maturation of the intestinal tract of young piglets and creating a good physiological environment for digestion and absorption in the intestinal tract of young piglets has become a hot spot in the field of piglet nutrition and feed development technology in recent years. [0003] At present, yeast has been widely used in piglet feed as a feed additive. [0004] Yeast belongs to the fungal phylum in clas...

Problems solved by technology

[0019] The technical problem solved by the present invention is to overcome the defects in the preparation of piglet compound feed in the above-mentioned prior art, add Saccharomyces cerevisiae inoculum to the mixed feed, improve the protein level of piglets, improve the antioxidant activity of the body, and effectively improve its digestion and absorption rate and immunity; by adding a higher dose of phytase, phytic acid can be effectively enzymatically hydrolyzed, and zinc oxide is added in combination, which not only ensures timely and full use of phytase, but also enables exogenous phosphorus, zinc and other trace elements to be absorbed by piglets. Effectively digest and absorb, effectively promote the growth of piglets, effectively reduce the amount of zinc ions added, and reduce environmental pollution
