NOVELTY - A pig farming method involves selecting excellent boar, producing fermenting bed pad material by taking raw materials in greenhouse ground, adding middle pouring water and stirring for pouring process. The mixed raw materials are added with water, fermented and covered to obtain fermenting bed followed by cultivating pig on fermentation bed, collecting pig manure and litter for utilizing probiotics, spreading earthworm, maggots and fish manure, preparing fertilizer by discharging pig manure, applying starch and liquid and allowing for anaerobic fermentation to obtain bio-organic fertilizer.    USE - Method for farming pig.    ADVANTAGE - The method enables farming pig with increased amount of pigs and increased resource.    DETAILED DESCRIPTION - A pig farming method involves selecting excellent boar using self-propagation self maintaining a breeding method, producing fermenting bed pad material by taking raw materials such as 100 kg/m3 sponge, 35 kg/m3 buckwheat flour, 15 kg/m3 rice husk bran, 1.5 kg/m3 rice bran, 0.6 kg/m3 salt, 0.3 kg/m3 hydrogen phosphate, 0.3 kg/m3 urea, 0.9 kg/m3 honey, 30 kg/m3 soil and 180 kg/m3 water in greenhouse ground, adding middle pouring water and 25 kg/m3 strain, stirring uniformly for pouring process. The mixed raw materials is added with water to make the moisture content upto 50-53%, fermented at room temperature for 2-3 days, fermented at 55-60 degrees C for 9-12 days, covered with 15 cm high sawdust to obtain a fermenting bed. The rice husk mixture is allowed to stand for 12 hours after fermenting bed, sprayed with fermentation strain, followed by cultivating pig on fermentation bed for three years, collecting pig manure and litter from fermenting bed for utilizing probiotics, spreading earthworm, maggots and fish manure for feeding pigs, preparing fertilizer for cultivating pigs in greenhouse fermenting bed by discharging pig manure directly from the bed, applying 9-10 kg starch, 6-9 kg liquid in the bed after three years of cultivation and allowing for anaerobic fermentation for 15-19 days to obtain bio-organic fertilizer.
