The global shift away from individual gestation stalls toward group housing for pregnant sows represents one of the most significant farm animal welfare reform achievements of recent decades, though implementation quality varies widely.
Gestation stall reform illustrates both the potential and the complexity of farm animal welfare improvement. The principle — that preventing animals from turning around for months at a time is unacceptable — is clear. The implementation — designing group systems that avoid the fighting, injury, and dominance stress that poorly managed groups produce — requires expertise and investment. Effective reform requires both the regulatory push to eliminate stalls and the technical support to help producers implement group systems that genuinely deliver better welfare.
