The scientific evidence on gestation crate welfare impacts is extensive and essentially uncontested, providing a clear basis for welfare policy positions on this issue.
The scientific evidence on gestation crate welfare is one of the most comprehensive and consistent bodies of evidence in farm animal welfare science. Multiple independent research groups using multiple welfare outcome measures — behavioral, physiological, and neurological — have consistently documented significant welfare harm from gestation crate confinement. This is not a contested scientific question. The question is a policy and economic one: given this evidence, what should producers, retailers, governments, and consumers do? The scientific clarity provides a strong basis for advocacy positions that do not require uncertainty qualification.
