Abstract: In recent decades,zero emissionsfermentation bed technology has been used to solve the excreta of pig from polluting theenvironment in pig industry at home and abroad.But,in application,there exist many problems,such as,high temperature of the fermentation bed,high cost and the production of harmful gas.By combining the advantages and disadvantages of the fermentation bed raising pig method with cement floorraising pig method,this paper devise a new raising-pig method—thin mat fermentation bed method,which is more suitable for the south areas.Compared with the former pig feeding mode in the following aspects,such as:costs of mat,incidence ofdisease,slaughtering rate,water consumption,growth increment in weight,feed amount and the feed/gain ratio,the results show that the new method is more environmental friendly in saving labor,provincial medicine and water,which is anecological raising-pig method of low cost,low emission and no smell.

Key words: biological fermentation bed, thin mat, zero emission, ecological raising pig
