Pig-raising fermentation bacterial agent for biological and environment-friendly fermentation bed and preparation method thereof

Abstract

The invention discloses a pig-raising fermentation bacterial agent for a biological and environment-friendly fermentation bed and a preparation method thereof. The preparation method comprises the following steps of: firstly selecting seven strains of bacteria, namely Morchella sp. CGMCC (China General Microbiological Culture Collection Center) NO.5.496, Bacillus stearothermophilus CGMCC NO.1.1923, Bacillus stearothermophilus CGMCC NO.1.1866, Bifidobacterium thermoacidophilum CGMCC NO.1.2282, Bacillus subtilis subsp. subtilis CGMCC NO.1.108, Streptomyces anandii CGMCC NO.4.1314, Saccharomycescerevisiae CGMCC NO.2.2081 as production and fermentation parent agents, wherein the viable count of each production and fermentation parent agent is not less than 108 / ml; and then performing freeze-drying on the seven strains of the production and fermentation bacterial agents, fully and uniformly mixing according to the weight of each powder freeze-dried strain, and then performing vacuum packaging to obtain a complex bacterial agent. By using the fermentation bed manufactured by the fermentation bacterial agent, the odor of a pigpen can be obviously reduced, the breeding opportunities of flies and mosquitoes can be reduced, the immunity of pigs can be improved, the healthy growth of the pigs can be protected, and the fermentation bed simultaneously has the characteristics of simplicityin practical operation and simplicity in manufacturing of the fermentation bed.

Description

technical field [0001] The invention belongs to the technical field of microbial engineering, and relates to a microbial composite bacterial agent for raising pigs in a biological environment-friendly fermentation bed and a preparation method thereof. Background technique [0002] The history of human pig raising has been more than 2,000 years. The change of agricultural farming mode has created conditions for the gradual transformation of pig raising from semi-grazing mode to captive breeding mode; the rise of the feed industry and the further development of breeding technology have made the pig raising industry move towards professionalism. The growth potential of pigs has been brought into full play by the road of modernization, intensification, and scale; however, the high-density factory breeding mode has also brought new ecological problems: high doses of antibiotics, addition of trace elements and heavy metals, It not only destroys the ecological balance of animals, b...

[0002] The history of human pig raising has been more than 2,000 years. The change of agricultural farming mode has created conditions for the gradual transformation of pig raising from semi-grazing mode to captive breeding mode; the rise of the feed industry and the further development of breeding technology have made the pig raising industry move towards professionalism. The growth potential of pigs has been brought into full play by the road of modernization, intensification, and scale; however, the high-density factory breeding mode has also brought new ecological problems: high doses of antibiotics, addition of trace elements and heavy metals, It not only destroys the ecological balance of animals, but also deteriorates the external breeding environment, seriously affects the normal development and health of pigs, and greatly increases the incidence of pigs; the concentrated discharge of feces and sewage pollutes soil and water sources, causing serious breeding problems. Pollution has brought great damage to the ecological system on which human beings depend

[0006] At present, most of the similar domestic products are unidentified microbial complex flora collected from "indigenous bacteria" in nature, and some directly use bio-fermentation fertilizer strains and EM strains. Some fermentation agents are complicated to use, the actual heating rate is slow, and the degradation effect of feces and urine is poor, which is easy to cause dead beds; some strains of fermentation bed pigs are prone to respiratory and diarrhea diseases
