The welfare of sows during the 16-week gestation period is determined by housing system, feeding management, and social environment.
Gestating sow welfare under EU group housing requirements is significantly better than individual stall housing in terms of social behaviour and movement freedom. However, group systems require careful management to prevent aggression, particularly around feeding stations. Electronic sow feeders that identify individual animals and dispense correct rations prevent dominant animals from stealing food from subordinates. Maintaining appropriate body condition through gestation through accurate feeding ensures adequate reserves for lactation and reduces farrowing complications.
