Abstract: Aiming at the problems of the relationship model which including uniform content, data distribution and access data lowly in the management of pigs, the plan of pigs’ data stored in the XML document is proposed. According to the self-description of XML, all the data of a pig are saved in an XML document. And the breeding pedigree information are added in the XML document. The evaluation system of XML based on genetic breeding is designed. Through the use of XML documents centrally stored pigs’ data, administrators can easily query, analyze and transfer pigs’ data. Finally the precise management of pigs is achieved and the computational efficiency of genetic breeding can be raised.

Key words: Extensible Markup Language（XML） documents, swine-pedigree, Best Linear Unbiased Prediction（BLUP） model, genetic breeding, genetic relationship
