Farmed Pig Gestation Space and Welfare

Space allowance for gestating sows is one of the most debated welfare issues in pig farming, with gestation crates severely restricting movement and causing chronic physical and psychological suffering.

Key Facts

Gestation crates measure approximately 0.6m x 2.2m — too small for a sow to turn around
More than 6 million sows were still confined in gestation crates in the US as of 2023
The EU banned gestation crates except for the first 4 weeks after mating, effective 2013
Group housing allows natural behaviors but requires careful management to prevent aggression
Sows in crates show higher rates of stereotypic bar-biting, indicating frustration
Lameness and muscle atrophy are more common in crate-confined sows due to reduced movement
Major food companies including McDonald's and Walmart have committed to phase out crate pork

Welfare Considerations

Gestation crates represent one of the most acute animal welfare concerns in industrial agriculture. Sows spend approximately 16 weeks of each pregnancy unable to turn around, walk, forage, or engage in social behaviors. The restriction causes documented psychological suffering evidenced by stereotypies, as well as physical harm including sores from concrete flooring, urinary tract infections, and cardiovascular deconditioning. Group housing systems, while requiring more management skill to prevent fighting, allow far greater welfare. Electronic sow feeders enable individual feed delivery in group settings, addressing the key practical challenge of crate systems.

What You Can Do

Choose pork certified under welfare standards prohibiting gestation crates (RSPCA Assured, Animal Welfare Approved)
Contact supermarkets and food companies to ask about their gestation crate phase-out timelines
Support legislative efforts to ban gestation crates at state and national level
Reduce pork consumption or shift to plant-based alternatives to reduce demand pressure
Support Humane Society and ASPCA campaigns targeting gestation crate elimination
