Broiler Breeder Hunger: The Welfare Cost of Fast-Growth Selection

Broiler breeder birds are chronically food-restricted to prevent obesity and cardiovascular disease from the same genetics that drive their offspring's rapid growth. This creates a serious welfare paradox.

Key Facts

Broiler breeders are feed-restricted to 60-80% of ad libitum intake throughout their lives
Without restriction, broilers suffer heart failure, leg problems, and early death
Restricted breeders show persistent hunger-related behaviours including aggressive pecking
Corticosteroid levels indicate chronic stress in food-restricted flocks
Qualitative behaviour assessments show negative affective states in restricted birds
Alternative slower-growing genetics reduce restriction needs but lower commercial performance

Welfare Considerations

Broiler breeder hunger represents one of the most ethically troubling welfare issues in commercial poultry. The animals experience chronic frustration, competitive aggression, and physiological stress from deliberate underfeeding. This suffering is built into the breeding model. Transitioning to slower-growing genetics offers the most systemic welfare improvement, though at production cost.
