Application of Fuzzy Comprehensive Evaluating Method to Improving the Intensive Pig Raising System

Through Fuzzy Comprehensive Evaluating Method (FCEM), the single factor matrix and the weights are established by using data given by fifteen experts. Subsequently, the contents of the pig raising system in central China are sorted. It shows that the regulations of pig raising and management, and epidemic prevention play an important role in the intensive pig production. And the ways of pig raising, feeding, and housing density follow them. In addition, the climatic controlling and manure treatment will be the key points in the future. The results are consistent with the investigation data of six pig farms in central China. Therefore, the FCEM can be used as a new method to improve the intensive pig raising system.
