[0065] The composite fermented material is composed of fermented material in the following proportions by weight: 30 to 70 parts of Lactobacillus acidophilus fermented material (for example: 30 parts, 45 parts, 70 parts), 10 to 20 parts of Bacillus subtilis fermented material (for ...

Embodiment 2

[0081] A preparation method for microbial fermentation antibiotic-free feed, comprising the steps of:

[0082] 1. Preparation of bacterial strains: Lactobacillus acidophilus, Bacillus subtilis, Saccharomyces cerevisiae, Trichoderma longifolia, Aspergillus niger, and Aspergillus oryzae were taken as the starting bacteria, and the temperature was gradually increased for acclimation, extraction, and rejuvenation, respectively, to obtain strains capable of achieving resistance to strains. The target strains at the grain temperature, and then expanded and cultured separately to obtain a bacterial content of 1×10 7 ~1×10 8 Each bacterial strain liquid per g, that is, Lactobacillus acidophilus seed liquid, Bacillus subtilis seed liquid, Saccharomyces cerevisiae seed liquid, long handle Trichoderma seed liquid, Aspergillus niger seed liquid, Aspergillus oryzae seed liquid.

[0083] The above strains can be purchased from the China Industrial Microbiology Culture Collection Management...

Abstract

The invention discloses a microbial fermentation antibiotic-free feed, which comprises a batch and a composite fermentation material. The batch consists of the following raw materials in part by weight: 30 to 50 parts of corn, 20 to 40 parts of bean pulp, 5 to 20 parts of cotton seed meal, 2 to 5 parts of calcium hydrophosphate, 0.2 to 0.4 part of salt, 0.1 to 0.2 part of composite trace element, and 0.2 to 0.4 part of composite vitamin; and the composite fermentation material consists of the following fermentation materials in part by weight: 30 to 70 parts of lactobacillus acidophilus fermentation material, 10 to 20 parts of bacillus subtilis fermentation material, 20 to 35 parts of saccharomyces cerevisiae fermentation material, 1 to 3 parts of trichoderma longbrachiatum fermentation material, 1 to 3 parts of aspergillus niger fermentation material, and 1 to 3 parts of aspergillus oryzae fermentation material, wherein the weight ratio of the batch to the composite fermentation material is 96-92:4-8.

Description

technical field [0001] The invention relates to an animal feed, in particular to a microbial fermented antibiotic-free feed and a preparation method thereof. Background technique [0002] The addition of antibiotics to feed in the 20th century has brought about the rapid development of the global animal husbandry industry. However, long-term feeding of animals with antibiotic-added feed will produce drug-resistant strains in the body and cause problems such as drug residues in animal products. With the gradual improvement of people's living standards, consumers' demand for livestock and poultry products has transitioned from the pursuit of quantity to the pursuit of quality, so the practice of adding antibiotics to feed is becoming more and more restricted. Currently, in Europe, North America, Asia and other regions Many countries have banned the addition of antibiotics to feed. [0003] Developing antibiotic-free feed and solving the problem of drug residues from the sour...
