Bold eller Regular THE GOOD STORY
Positive aspects of organic pork production (compared to conventional)
Animals being able to express more of their species-specific (natural) behaviour
Markedly lower use of antibiotics
Organic producers are paid three times as much per kg of pork (represents a significant
value increment in the Danish pig production)
Plays a central role in the success story of Danish organic exports

Environmental impacts - compared to conventional production
Requires 30 % more land
Comparable in terms of greenhouse gas emissions (global warming)
Higher ammonia losses
