Advantages of fermented feed:
（1）Change the traditional intestinal maintenance mode to minimize the harm of intestinal diseases;
（2）Decompose mycotoxins in feed and eliminate the hidden hazards of mycotoxins;
（3）It can make the pig's feces discharged from the body as soon as possible, decompose the harmful gases such as ammonia, hydrogen sulfide and sulfur dioxide in the feces, and purify the air quality of the barn.
（4）Fermented feed can effectively improve the intestinal system, improve the utilization of feed, and induce the immune system of pigs to produce a variety of cellular immune factors, and promote the production of interferon and antibody.
（5）Reduce the use of antibiotics, reduce the harm of drugs to animals.
Common strains and growth conditions of fermented feed
China is rich in microbial resources. The microorganisms used in industrial fermentation mainly include bacteria, actinomycetes, yeasts and molds. The common strains in feed industry include Bacillus subtilis, Bacillus licheniformis, Lactobacillus plantarum, Lactobacillus acidophilus, Acetobacter, Pediococcus pentosaceus, Candida utilis, Saccharomyces cerevisiae, Aspergillus niger and Aspergillus oryzae. The suitable growth temperature of common feed bacillus is 30℃～37℃, pH is 7.0～7.2; the suitable growth temperature of common feed lactobacillus is 30℃～37℃, pH is 5.5～6.0; the suitable growth temperature of common feed yeast is 24℃～32℃, pH is 3.0～6.0; the suitable growth temperature of common feed mold is 25℃～30℃, pH is 3.0～6.0.
