Standard breeding pattern of pig production in China and analysis of its technology level.

Based on the investigation at 241 standard pig farms from 28 provinces in China,this paper systematically reflected the present situation of standard pig production pattern in China.It also analyzed the pig production and market patterns,reproduction and breeding system,feed quality monitoring,comprehensive disease control,pigpen design and environmental control,etc.important factors.The results indicated that in China the pig breeding and production patterns were multiple,the standardization were gradually formed.The integration breeding pattern was the major standard breeding pattern.Besides,this paper summarized the investigation participants' demands for pig standardization development,standard technical innovation and breeding pattern,and put forward several suggestions for the reference of relevant departments of policy-making,industrial technology research,development and extension.
