Microbial fermentation antibiont-free concentrated feed for pigs

Abstract

The invention discloses a microbial fermentation antibiont-free concentrated feed for pigs. The concentrated feed is prepared from the following raw material components in parts by weight: 100 parts of corn flour, 38 parts of bean pulp, 5 parts of Chenopodium album, 25 parts of spray protein, 25 parts of spray bran, 4 parts of compound trace elements, 5 parts of multivitamin, 10 parts of an enzyme additive and 25 parts of a fermented material additive, wherein the fermented material additive consists of lactobacillus plantarum, lactobacillus rhamnosus, bacillus licheniformis and lactic acid bacteria lactobacillus according to a mass ratio of 2:1:1:1; the compound trace elements consist of 30 percent of ferrous sulfate monohydrate, 8 percent of blue copperas, 9 percent of manganese sulfate monohydrate, 4 percent of zinc sulfate monohydrate, 2 percent of potassium iodide, 11 percent of calcium iodide and 36 percent of zeolite powder; and the enzyme additive consists of amylase, cellulase, protease and lipase according to a mass ratio of 2:1:1.5:1. The concentrated feed disclosed by the invention, without antibiotic drugs, is high in content of beneficial microorganisms and high in palatability, and can obviously improve the health level of pigs.

Description

technical field [0001] The invention relates to a feed for pigs, in particular to a microbial-fermented non-antibiotic concentrated feed for pigs. Background technique [0002] At present, antibiotics are added to most feeds. Although this will increase the production of aquaculture, it will produce drug-resistant strains in animals and cause drug residues, which directly threaten human health. Therefore, improving feed quality and production Antibiotic-free materials are the most effective means to solve drug residues in animals. [0003] Antibiotic-free feed uses microorganisms and compound enzymes as biological feed starter strains to convert feed materials into microbial cell protein, bioactive small peptide amino acids, microbial active probiotics, and compound enzyme preparations. It not only increases the amino acid content in the feed, but also accelerates the conversion of other roughage nutrients. [0004] The existing antibiotic-free feed for pigs generally ...
