Live pig breeding fermentation bed technology

Abstract

The invention provides a live pig breeding fermentation bed technology which comprises: mixing raw materials, including 85-90% by weight of original sawdust, 10-15% by weight of unpolluted local soil and 0.5% by weight of large-grain original sea salt, with water to obtain bedding with the relative humidity of 60-70%; adding 0.7Kg per square meter of an indigenous bacteria strain and carrying out fermentation for 7-10 days; immediately adding the original sawdust when the bed surface descends by 25-35 cm, spraying a nutrient solution with the concentration of 0.1% when the relative humidity is less than 60%, and when the pig manure is accumulated, immediately scattering and dispersing pig manure or uniformly mixing the pig manure with the bedding and burying the mixed material into middle and lower layers of the bedding; after pigs are output, overturning and stacking the bedding, covering the bedding with a plastic film and carrying out fermentation for 7-10 days, then adding 0.7Kg per square meter of the indigenous bacteria strain and the nutrient solution with the concentration of 0.1% for adjusting the relative humidity to be 60-70%, and carrying out fermentation for 7-10 days for repeated use. The technology has the beneficial effects that for the bed which is used for 5 years, the problem of rotten and dead beds is avoided.

Description

technical field [0001] The invention relates to a technology for pig breeding, in particular to a pig breeding fermentation bed technology. Background technique [0002] Fermentation bed pig raising is a new pig raising technology introduced from Japan, South Korea and other countries located in sub-frigid regions in recent years. Fermentation bed pig raising technology is based on ecological principles, using probiotic resources, combining microbial biotechnology, fermentation technology, Aquaculture technology and engineering technology are a comprehensive technology used in modern aquaculture. Fermentation bed pig raising technology can achieve zero discharge of feces and urine, improve the breeding environment, reduce the incidence of pig diseases, improve animal welfare, improve efficiency, make the breeding industry better integrated into the agricultural ecological cycle system, and promote the circular development of ecological agriculture.

Problems solved by technology

Among the many domestic pilot units that have carried out fermented bed pig raising experiments, because they have not studied and mastered a set of effective fermented bed technology that is suitable for local conditions, the fermented bed is often rotten and dead, resulting in the failure of the fermented bed pig raising test; As a result, the cost of raising pigs in the pilot unit has risen, the profit has dropped sharply, and even losses have become unsustainable
