NOVELTY - A fermented sheep mattress material producing method involves preparing biological fermentation agent and mixing sheep dung, straw, sawdust, vermicompost, lees, herbal mixture, fermentation agent and cellulose. The obtained compost mixture is subjected to aerobic fermentation and anaerobic fermentation. Seaweed, lactic acid powder, Bifidobacterium bifidum, Bacillus subtilis, Bacillus licheniformis are mixed with fermented compost and three step fermentation is carried out. The obtained fermented material is crushed and the obtained crushed material is dried.    USE - Method for producing fermented sheep mattress material that is utilized for pig cultivation.    ADVANTAGE - The method enables producing fermented sheep mattress material, which can reduce pig disease rate and promote growth of pig.    DETAILED DESCRIPTION - A fermented sheep mattress material producing method involve preparing biological fermentation agent by evenly mixing 10 pts. wt. adsorbent, 5 pts. wt. calcium dihydrogen phosphate, 6 pts. wt. fermented beans Parker, 15 pts. wt. rice bran, 15 pts. wt. corn flour, 5 pts. wt. rapeseed cake, 10 pts. wt. wheat bran, 2 pts. wt. effective microorganism agents, 1 pts. wt. Aspergillus niger, 2 pts. wt. Bacillus subtilis, treating mixture with 2% aqueous solution containing molasses to adjust moisture content of 35-40% and carrying out anaerobic fermentation at 25-30 degrees C for 3-5 days. 60-70 pts. wt. Sheep dung, 20-30 pts. wt, straw, 10-20 pts. wt. sawdust, 5-10 pts. wt. vermicompost, 2-3 pts. wt. lees, 0.5-1 pts. wt. herbal mixture, 2-3 pts. wt. fermentation agent and 1-2 pts. wt. cellulose are mixed and moisture of the mixture is adjusted to 35-40% by using 2% aqueous solution containing molasses. The obtained compost mixture is subjected to aerobic fermentation for 3-5 days after mixing and regularly stirring, and subjected to anaerobic fermentation for 2-3 days. 2-3 mass% Seaweed, 2-3 mass% lactic acid powder, 1-2 mass% Bifidobacterium bifidum, 1-2 mass% Bacillus subtilis, 1-2 mass% Bacillus licheniformis are evenly mixed with fermented compost. The obtained mixture is treated with 2% aqueous solution of molasses to adjust moisture content to 35-40%. The obtained material is subjected to three step fermentation at 28-35 degrees C and natural composting for 3-5 days. The obtained fermented material is ground by using semi-wet material grinder to obtain crushed material with grinding fineness of 20-30 mesh. The crushed material is dried until the moisture content reaches 30-40% to obtain fermented mattress.
