This traceability system included information managements for pig breeding and pig quaran- tine inspection supervision. It also realized the record and supervision of pig information, feed usage, veterinary drug usage and quarantine inspec- tion. We mainly introduced the designs of systemic structure and functional structure of the traceability system and key techniques of system imple- mentation.展开更多
