Farm Broiler Fast-Growing Breed Welfare Reform

The shift away from fast-growing broiler breeds toward slower-growing strains is one of the most significant potential welfare improvements available to the chicken industry.

Key Facts

Standard commercial broilers reach slaughter weight in 35-42 days, triple the growth rate of chickens from 1950
Rapid growth causes heart failure, ascites, leg disorders, and chronic pain that affect a significant proportion of birds
Slower-growing breeds such as Hubbard JA57 and Rambler reach target weight in 56-63 days with markedly better health outcomes
Gait scoring studies show slower-growing birds walk significantly better and show fewer lameness indicators
The European Chicken Commitment adopted by major food companies requires transition to slower-growing breeds with higher welfare standards
Breed reform costs approximately 10-20 cents per kilogram of chicken — a small premium for substantial welfare improvement
Welfare research shows slower-growing breeds engage more in natural behaviors including foraging, dust bathing, and perching

Welfare Considerations

Fast-growing breed selection is arguably the single most welfare-damaging decision in broiler chicken production, and it is one that can be reversed through market pressure and corporate commitments. The suffering caused by rapid growth — heart failure, chronic lameness, and respiratory distress — affects billions of individual animals each year. The European Chicken Commitment provides a concrete framework for industry transition, and companies that have signed and are implementing it are making real welfare improvements. Consumer awareness of breed welfare and active support for higher-welfare chicken products are key drivers of continued progress.
