Farmed Broiler Parent Hunger Restriction Science

Broiler parent birds are feed-restricted to prevent welfare problems caused by over-rapid growth, creating a welfare dilemma between competing harms.

Key Facts

Broiler parent birds if fed ad libitum develop obesity, skeletal problems, and heart failure
Feed restriction programmes maintain body condition but cause chronic hunger
Restricted parent birds show stereotypic oral behaviours indicative of hunger frustration
The dilemma arises from genetics selected primarily for offspring growth rate
Developing less growth-efficient but healthier parent stock would reduce both harms

Welfare Considerations

Broiler parent welfare involves a genuine ethical dilemma: either chronic hunger or early death from overconsumption. The root cause is genetic selection. Long-term solutions require industry commitment to breeding birds with a lower growth trajectory that do not require restriction.

What You Can Do

Support companies committed to transitioning to slower-growing broiler breeds
Advocate for genetic research prioritising health and welfare in parent stock
Choose chicken from producers transparent about parent stock welfare
