Abstract:

Based on the rapid tendency of application of microbial fermentation bed in pig farming in recent years, ecological security problems were investigated. The results of the study show that the ecological security problems are not merely due to the skill system but are the lack of appropriate management measures.There is therefore an urgent need to draft out a set of appropriate management measures, such systems should included alternative and management technology for bedding materials, source control system for feed, recycling technology for waste.
