Broiler Genetic Selection Welfare Consequences

Genetic selection for rapid growth in broiler chickens has created birds with structural health problems that are endemic to the production system.

Key Facts

Modern broilers reach market weight in 35-42 days, half the time of 1950s birds
Rapid growth causes cardiovascular disease, ascites, and skeletal disorders in a significant percentage
Slow-growing breeds take 56+ days but have dramatically lower welfare-compromising disease rates
EU and UK welfare schemes increasingly require slower-growing breeds
Consumers pay a premium for slower-grown chicken that reflects higher welfare costs

Welfare Considerations

The genetics of modern broiler chickens predispose them to painful, life-limiting conditions as a direct result of selection for production efficiency. This is one of the most widespread welfare problems in global food production, affecting tens of billions of birds annually.

What You Can Do

Choose chicken certified under schemes requiring slower-growing breeds
Support the Better Chicken Commitment campaigns in your country
Advocate for genetic selection criteria that prioritize welfare alongside growth rate
