BACKGROUND
EFFECTS ON ENVIRONMENT
EFFECTS ON ANIMAL WELFARE
Normal gait with no detectable abnormalitySlightly uneven gait, difficult to define and identify defectDefect in gait without hindering movement or accelerationGait defect affecting the ability to move, and accelerateSevere gait defect, moving only when encouragedIncapable of sustained walking
PREVALENCE OF FOOT PAD DERMATITIS IN BROILERS, DK 2002-2005
A. Up to 40 points ≈ up to 20% severe lesionsB. 41-80 points ≈ up to 40% severe lesionsC. 81-200 points ≈ up to100% severe lesions
OTHER ISSUES
Other issues• Public health
– Foodborne diseases (Salmonella, Campylobactor ...)– Pandemies (Avian flu, ...)
• Nature protection• ...
CONCLUSION – THE DILEMMA OF BROILER
PRODUCTION
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
