The shift from Broad-Breasted White turkeys to slower-growing heritage and alternative breeds offers the most fundamental welfare improvement available in commercial turkey production.
Turkey breed reform addresses welfare at the most fundamental level - the genetic foundation of what commercial turkeys are. The Broad-Breasted White's body shape creates welfare problems that management cannot solve: cardiovascular stress from supporting excessive breast muscle, walking difficulties that become severe as birds age, and inability to perform natural behaviors. These are not failures of management or housing - they are inherent consequences of what the bird has been bred to be. Slower-growing breeds, by being less extreme in their conformation, avoid these inherent welfare compromises while still producing commercially viable birds. The slower growth rate is itself a welfare indicator, not merely a production variable.
