Broiler Feed Restriction and Welfare Implications

Understanding the welfare trade-offs of feed restriction programmes in broiler breeders and fast-growing meat chickens.

Key Facts

Broiler breeder hens are feed-restricted to 25-50% of ad libitum intake to prevent obesity-related health problems
Restricted birds show persistent hunger behaviors including feeder-directed stereotypies
Fast-growing commercial broilers experience leg problems at rates up to 30% partly linked to rapid growth
Alternative slower-growing breeds reduce leg disorder prevalence but increase resource use per unit production
Feed restriction in breeders impairs immune function and increases stress-related behaviors

Welfare Considerations

Feed restriction creates a genuine welfare dilemma: unrestricted broiler breeders suffer obesity, cardiovascular disease, and reproductive failure, while restriction causes chronic hunger and frustration. No current solution resolves both problems. This highlights why genetic selection for extreme growth rate creates ongoing welfare challenges requiring systemic change.

What You Can Do

Support research into moderate-growth genetic lines that reduce the need for severe restriction
Choose poultry products from slower-growing breeds certified by higher-welfare schemes
Advocate for breed standards that prioritize health over maximal growth rate
Learn about Better Chicken Commitment criteria and support brands that have signed it
Encourage transparent labelling of breed type on poultry products
