Commercial turkey production uses breeds selected for extreme breast muscle growth that compromises locomotion, cardiovascular health, and natural breeding capacity.
Commercial turkey welfare is compromised at the genetic level — the commercial broad-breasted white breed has been selectively developed to the point that its body architecture prevents natural reproduction and causes progressive locomotion problems as it grows. This is a welfare problem built into genetics through selection pressure that prioritized breast meat yield above all other traits. The parallel to broiler chickens is direct — rapid growth rate has been maximized while welfare traits including cardiovascular health, locomotion, and natural behavior have been sacrificed. Lame turkeys experience chronic pain with every step during weeks of growth. Heart failure from cardiovascular strain causes sudden death in apparently healthy birds. The inability to mate naturally is itself an indicator of how far selective breeding has departed from physiological function. Heritage breed alternatives demonstrate that turkey production without these welfare harms is possible.
