Development on mobile traceability system of feeding process of pigs and quality safety of its meat products based on 3G technology

In view of existed not flexibility and low efficiency in establishing feeding file of large-scale farms or farmer farms of pigs，by adopting intelligent PDA or mobile phone as application platform, combining with .Net 2005 language and SQL Server 2005 CE database as well as TD-SCDMA wireless wide band communication linking Internet as data transmission method, this study suggested data criterions on feeding process information collection of pigs, and developed a mobile PDA or phone system to track swine feeding process data, such as operators and main inputs, and to trace pork quality safety. The running of the system shows that it realized all kinds of data collecting and wireless submission including ear tag wearing and movements, immunity events, feeds and veterinary drugs used as well as casual inspection data，and also achieved remote data maintaining for pig's feeding files and deepness inquiry to pork quality. The system not only makes up a deficiency from table data recording system for feeding file setting of a large-scale swine farm, but also is a kind of effective solution for farmer farm to set up swine feeding files. Furthermore, the system is a kind of mobile and convenient supervising tool to service official veterinarian to carry out their work. Finally, with the TD-SCDMA technology prevalence and communication fee decrease, the system will take part in a important role in constructing Chinese pork quality safety traceability system.
