Broiler Chicken Breast Pathologies

Modern broiler chickens grow so fast that many develop painful musculoskeletal diseases before slaughter.

Key Facts

Modern broilers reach slaughter weight in just 42 days
Growth rates have increased 400% since the 1950s
Up to 30% of broilers show signs of lameness
Wooden breast disease affects up to 50% of fast-growing breeds
Ascites and heart failure are common due to rapid growth

Welfare Considerations

The extreme growth rates selected for in modern broiler breeds cause widespread suffering. Skeletal systems cannot keep pace with muscle growth, leading to painful leg deformities. Wooden breast disease causes painful muscle inflammation. Many birds spend their final weeks unable to walk properly, unable to reach food and water, in chronic pain.
