Scientific comparison of broiler breed welfare outcomes demonstrates that slower-growing breeds consistently outperform fast-growing breeds.
Comparative welfare science between fast and slower-growing broiler breeds consistently shows that slower-growing birds have better gait scores, lower mortality, more time spent active, and fewer cardiovascular problems. The welfare gains are substantial across multiple indicators. Cost differences are modest relative to welfare improvements achieved. Corporate commitments from hundreds of major companies demonstrate market viability of the transition.
