Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feed fermentation equipment, in particular to solid-liquid two-phase fermentation equipment for feed production with a drying function. Background Art
[0002] Feed fermentation is usually carried out by natural fermentation and fermentation by inoculating commercial lactic acid bacteria. The quality of feed produced by natural fermentation is generally unstable, and it is easily infected by miscellaneous bacteria, and the feeding effect of pigs varies greatly. The quality of feed produced by inoculating commercial lactic acid bacteria is easier to control, but the cost is relatively higher.
[0003] Roughage is made from microbial fermentation and is a fermented feed. Roughage is rich in crude fiber and protein such as cellulose, hemicellulose, pectin, lignin, etc., but it is difficult for animals to digest and absorb directly. Eating it will increase the burden on the intestines of animals and cause intestinal diseases. This product can not only make up for the amino acids that are easily lacking in conventional feeds, but also quickly convert the nutrients of other roughage raw materials to enhance digestion, absorption and utilization.
[0004] Fermented feed is a biological fermented feed that uses microorganisms and complex enzymes as biological feed fermentation strains to convert feed raw materials into microbial bacterial proteins, bioactive small peptide amino acids, microbial active probiotics, and complex enzyme preparations.
