ABSTRACT
This chapter focuses on the use of gestation stalls in sow confinement facilities. Gestation stalls are metal cages used to confine sows during nearly the entire duration of their four-month pregnancy. The dimensions of gestation stalls are such that the sows confined in them can only take one step forward and one step back. The American Veterinary Medical Association’s policy statement on pregnant sow housing cites advantages of gestation stalls: Gestation stall systems may minimize aggression and injury, reduce competition, and allow individual feeding and nutritional management, assisting in control of body condition. These advantages largely mirror those identified in the National Pork Board’s position statement on gestation stalls. A survey of the considerations the industry offers in favor of gestation stalls in sow production, though, helps to show that what it means for a producer to take an interest in animal welfare is quite different from what we might expect.
