Biological fermentation feed and preparation method thereof

Abstract

The invention relates to a biological fermentation feed and a preparation method thereof, belonging to the field of solid feeds. The biological fermentation feed provided by the invention is prepared from a compound bacteria solution and a fermentation substrate through fermentation, wherein the compound bacteria solution comprises bacillus subtilis, composite saccharomycetes, lactic acid bacillus and bifidobacterium species; the fermentation substrate comprises the following components in parts by weight: 30-35 parts of corns, 10-15 parts of soya bean meal, 25-35 parts of rice washing bran, 10-15 parts of wheat bran, 3-8 parts of yeast extract powder, 0.5-2 parts of sodium chloride, 1-5 parts of calcium hydrophosphate, 0-3 parts of soybean oil, 0.5-1.5 parts of manganese sulfate and 0.5-1.5 parts of magnesium sulfate. The biological fermentation feed provided by the invention is free from antibiotics, is green and safe, is prepared from the raw materials with wide sources, is large in maneuverability, has remarkable benefits, and is capable of reducing morbidity of various diseases.

Description

technical field [0001] The invention relates to biologically fermented feed and a preparation method thereof, belonging to the field of solid feed. Background technique [0002] With the improvement of people's living standards, the demand for green food and pollution-free food is getting higher and higher. Pork and its organs, as the traditional meat of the Chinese people, have attracted more and more attention. At present, there are many types of commonly used feed for pigs, which can be divided into 8 categories according to nutrition: protein feed, energy feed, roughage, green feed, silage, mineral feed and feed additives. Although various feeds have their own unique effects, there are also requirements for the feed mix of different breeds of pigs, especially the anti-nutritional factors in plant, animal and mineral substances are not conducive to the digestion and absorption of pigs. At the same time, in the production of pork pigs, excessive use of antibiotics and abu...

Problems solved by technology

The feed does not add any antibiotics and is fermented from three kinds of probiotics, which can promote animal growth and have a certain effect on maintaining the balance of intestinal flora. However, the dry substrate cost of this feed is relatively high, and after the fermentation It is also necessary to add a premix composed of vitamins, biotin, choline chloride, etc., the production process is complicated and the cost is high
