Broiler Breeder Welfare and Feed Restriction

Parent birds of fast-growing broiler breeds must be severely feed-restricted to prevent obesity-related health problems, creating a chronic hunger state that compromises welfare.

Key Facts

Broiler breeders (parent birds) must be restricted to 25-30% of their ad libitum feed intake
Without restriction, parent birds develop obesity, heart failure, and leg problems
Feed restriction causes chronic hunger, frustration, and aggressive competition for food
Behavioral indicators of hunger persist even when birds appear physically healthy
Slower-growing breeds have much lower restriction requirements due to reduced obesity risk

Welfare Considerations

Broiler breeders live in a state of chronic hunger that welfare scientists consider one of the most significant welfare problems in commercial poultry production. These birds are genetically predisposed to rapid growth and unlimited eating, yet must be kept permanently hungry to survive to productive age. The frustration of unfulfilled hunger motivation causes persistent stereotypies, heightened aggression, and food-related anxiety. Transitioning to slower-growing parent breeds reduces this welfare compromise substantially.
