PREVALENCE OF FOOT PAD DERMATITIS IN BROILERS, DK 2002-2005 • Up to 40 points ≈ up to 20% severe lesions • 41-80 points ≈ up to 40% severe lesions • 81-200 points ≈ up to100% severe lesions
Other issues • Public health • Foodborne diseases (Salmonella, Campylobactor ...) • Pandemies (Avian flu, ...) • Nature protection • ...
CONCLUSION – THE DILEMMA OF BROILER PRODUCTION • On the one hand broiler production • delivers nutritious and cheap food • with relatively small effects on the environment • On the other hand broiler production • has huge negative effects on animal welfare
