Abstract
The invention discloses a feed fermentation stirring device used in a method for preparing fermented feed by combining bacteria, enzyme and prebiotics with fermentation treatment of mildew feed raw materials, the feed fermentation stirring device comprises a device box, a partition plate, an active component and a passive component, wherein the partition plate is arranged inside the device box and divides the device box into a first cavity and a second cavity, and the active component and the passive component are arranged inside the first cavity in a sliding manner and extend to the inside of the second cavity. According to the invention, the driving component can be driven to move through the driving component, the driving component drives the driven component to move, the plugging component and the pressing component in the driving component and the driven component are matched to tightly press bacteria into the raw material and pump part of the raw material, the rotating component and the sucking component are matched to suck part of bacteria liquid and transport the bacteria liquid to the bottom end in the raw material for release, the two components can rotate, and the two components are matched to effectively and uniformly mix the raw material and the bacteria liquid, so that the effect is remarkable.
Description
Technical Field
The invention relates to the technical field of feeds, in particular to a method for preparing fermented feeds by combining bacteria, enzymes and prebiotics with fermentation treatment of mildewed feed raw materials.
Background
The feed raw materials refer to feeds which take an animal, plant, microorganism or mineral as a source in feed processing, and comprise grains, raw grains, soybeans, soybean meal, corn, fish meal, amino acid, miscellaneous meal, additives, whey powder, grease, meat and bone meal, grains and other varieties, wherein the feed raw materials are deliquescent and mildewed due to higher moisture content, the problem of mildew of the feed raw materials can seriously affect the breeding efficiency of animals, and the mold can quickly deteriorate the fat of the feed, reduce the protein digestibility, seriously reduce the lysine and arginine levels in the feed, reduce the metabolism of the feed, reduce the weight gain of the animals, increase the burden of livers and kidneys, interfere with the physiological process of reproduction and destroy an immune system, so the prior art can utilize bacteria, enzymes and probiotics to combine fermentation treatment to convert the feed raw materials into the biological fermentation feed of the feed which is integrated with microbial mycoprotein, bioactive small peptide amino acid, microbial active probiotics and a compound enzyme preparation, can make up for the amino acid which is easily lacking in the conventional feed, and can quickly convert other crude feed raw material nutrition components, enhance the digestion and absorption and utilization effects.
However, when the existing fermented feed mixes the mildew feed raw materials with the starter strains such as microorganisms, the starter strains such as microorganisms cannot be effectively mixed by using a common mixing device, so that the starter strains such as microorganisms cannot be completely mixed with the mildew feed raw materials for fermentation, the mildew feed raw materials can be possibly mixed in the starter strains, the quality of the fermented feed is affected, the production of the fermented feed is disqualified, and the problems such as animal diarrhea and poisoning are easily caused.
Disclosure of Invention
The invention aims to provide a method for preparing fermented feed by combining bacteria, enzymes and prebiotics with fermenting and processing mildewed feed raw materials so as to solve the problems in the prior art.
In order to achieve the above purpose, the present invention provides the following technical solutions: a method for preparing fermented feed by combining bacteria, enzyme and prebiotics with fermentation treatment of mildewed feed raw materials, wherein the mildewed feed raw materials comprise mildewed corn and mildewed sorghum, and the method for preparing the fermented feed comprises the following steps:
