Complex microbial inoculum for swine production by fermentation bed started quickly at low temperature and preparation method thereof

Abstract

The invention discloses a complex microbial inoculum for swine production by a fermentation bed started quickly at low temperature and a preparation method thereof. The complex microbial inoculum comprises the following microorganisms: 15-20% of trichoderma, 15-20% of bacillus subtilis, 15-20% of rhodopseudomonas spheroids, 15% of lactobacillus acidophilus, 15% of yeast and 15% of streptomyces avermitilis. The preparation method of the complex microbial inoculum comprises the steps of inoculating and propagating the microorganisms till each microorganism contains 108 viable bacteria per ml; mixing the microorganisms together according to the proportion thereof; and inoculating the mixed microorganisms in a low-cost culture medium for culturing to obtain the complex microbial inoculum. When used for fermenting fillings in a fermentation bed, the complex microbial inoculum has the advantages of fast temperature rise from low temperature of 0 DEG, strong deodorization function, short fermentation cycle and the like. The production cost of the complex microbial inoculum is 20% lower than that of the similar product. In addition, the complex microbial inoculum realizes continuous loop fermentation process of the fermentation bed in fermentation bed swine production, effectively solves the problem that livestock matures of large-scale culturing farm pollutes the environment, and also realizes the comprehensive development and utilization of waste resources.

Description

technical field [0001] The invention relates to the field of preparation of microbial inoculum, in particular to a low-temperature quick-start pig-raising composite microbial inoculum and a preparation method thereof. Background technique [0002] Fermentation bed pig raising technology is a theory that integrates biological fermentation, ecological cycle, health immunity, environmental control, and animal husbandry production. It is based on the establishment of a micro-ecosystem fermentation bed consistent with the local environment. It is a new eco-environmental protection pig raising technology that is characterized by zero emission and aims at producing safe livestock products. This technology first started in Japan in the 1970s, and then Europe, America and other countries successively carried out research and promoted it. [0003] In the 1990s in our country, some provinces and cities carried out experimental demonstrations of fermentation bed culture technology, but...

AI Technical Summary

Problems solved by technology

[0003] In the 1990s in our country, some provinces and cities carried out experimental demonstrations of fermentation bed culture technology, but they have not been further popularized and applied. In recent years, Gansu Province has gradually introduced and vigorously promoted this technology, but due to the lack of suitable microbial agents The product and the matching technology cause the cost of raising pigs in the fermentation bed to be too high and the production is unstable, so it is difficult to promote in practical application

[0004] Gansu Province is located in a high-altitude area, and the indoor and outdoor temperatures are low in winter (average below 0°C). Using existing microbial inoculant products, most of the fermentation beds are difficult to work normally in winter without heat preservation devices and measures. Start-up and maintenance, especially in high-altitude mountainous areas, where the temperature in winter is below -10°C. If indoor heating facilities are not used, it usually takes 10-20 days to reach the normal temperature for pigs to enter when using general fermentation bed microbial agent products. (around 38°C)
