Broiler Breed Selection and Welfare Trade-offs

The genetics of broiler chickens have been intensively selected for rapid growth, creating breeds with serious welfare problems that alternative breeds can largely avoid.

Key Facts

Modern fast-growing broilers reach slaughter weight in 35 to 42 days
Fast-growing breeds have up to 50% higher incidence of leg disorders than slower breeds
Cardiovascular problems including ascites affect fast-growing breeds at high rates
Slower-growing breeds such as Hubbard JA and ROSS 308 alternatives show better outcomes
The European Better Chicken Commitment requires transition to slower-growing breeds

Welfare Considerations

Fast-growing broilers live in a state of chronic physiological stress due to the demands their body size places on underdeveloped skeletal and cardiovascular systems. Lameness causes pain and prevents access to food and water. Transitioning to slower-growing breeds with enriched environments is the single most impactful intervention available for broiler welfare improvement.

What You Can Do

Support the Better Chicken Commitment by choosing certified brands
Ask retailers and restaurants about breed standards in their chicken supply chains
Look for RSPCA Assured or equivalent certification on chicken products
Reduce chicken consumption or choose products from verified slower-growing breeds
Advocate for breed transition requirements in government farm welfare policy
