Electronic sow feeding systems allow individual feeding of group-housed sows, addressing both behavioral needs and nutritional requirements simultaneously.
Electronic sow feeding represents a technological solution to the welfare challenge of managing individually fed animals in group housing. Gestation stalls deliver reliable individual nutrition but at the cost of near-total movement restriction for months. Group housing with ESF provides behavioral freedom — sows can move, socialize, and exercise — while maintaining individual nutritional control. The transition requires investment in systems and stockperson skills for group management, but welfare outcomes in well-managed ESF systems are substantially better than gestation stalls. The ban on gestation stalls in multiple countries has accelerated transition to these better systems.
