Modern commercial turkeys have been selectively bred to grow so rapidly that chronic pain and cardiovascular problems are nearly universal, raising serious welfare concerns.
Turkey welfare represents one of the clearest examples of selective breeding creating inherent welfare compromise. The extreme muscle mass selected for commercial production causes skeletal, cardiovascular, and metabolic problems from an early age, meaning most commercial turkeys live in chronic pain. Unlike many welfare problems that can be addressed through management changes, the welfare deficits in fast-growing commercial turkeys are built into their genetics and cannot be adequately addressed without a shift to slower-growing breeds.
