In this paper, the research based on decision tree-based methods can be customized to achieve a common data analysis system for animal husbandry intelligent decision support, conducted the following study: First, detail the current data mining techniques and animal husbandry areas where the decision tree method for various applications, purpose, content and methods. Secondly, the theoretical basis of the data mining system, basic theory and the theory of decision tree methods of animal husbandry intelligent decision system, which constitute the theoretical basis of the study. Third, given the detailed design of common animal husbandry intelligent decision system based decision tree method. Detailed descript of the specific work processes and systems function modules of the system on the line division. To complete the design of the database based on the completion of the system design.
