Farmed Pig Precision Feeding Systems

Electronic sow feeding systems allow individual nutrition management for group-housed sows, improving welfare compared to competitive feeding.

Key Facts

ESF systems recognize individual sows via transponders and dispense exact rations
Reduced competition at feeders decreases aggression and injury
Sows can be monitored individually for health changes through feed intake data
Transition from stall housing to group ESF systems requires careful management

Welfare Considerations

Electronic sow feeding is a welfare improvement over competitive feeding in large groups, as it allows all sows to receive their required nutrition without bullying. However, the transition from stall housing requires careful social management to prevent aggression in newly grouped animals.
