Pig Flow Dynamics in Wean to Finish Systems

The advantages of wean-to-finish flow have been reported previously. This technology has been adapted by many production companies across the United States and has proven itself to be a useful means of rearing wean to market pigs. Wean-to-finish has been successful because it has allowed all-in/all-out flow by site in many sizes of swine herds. It allows smaller swine herds to adopt multi-site technology and it has allowed large production companies to maintain sow herd integrity in the pig flow while maintaining multi-site production. It has also been praised for its logistical simplicity, its flexibility in flow and its economic benefits to production systems.
