Are organic pigs better off?
Besvaret 26. oktober 2026
Organic pigs must get twice the indoor space plus outdoor access, and they show more natural behaviour. But they are not healthier on every count.
Under the Danish organic rules, a finishing pig of 85 to 110 kg needs 1.3 m² indoors and 1.0 m² outdoors, against 0.65 m² for a conventional pig. All pigs must have permanent outdoor access, rooting material and roughage. Tail docking of pigs is not on the list of procedures that can be exempted.
A systematic review of 166 studies found more natural behaviour, but names piglet deaths, leg problems and parasites as major issues. In a 2015 Danish slaughterhouse study, organic and free-range pigs more often had tail wounds and old fractures, but fewer hernias and leg abscesses. The authors work for the Danish Agriculture & Food Council. An Aarhus University researcher calculates that the rarer lesion types make up 74 percent of all lesions found. Another Danish study found less tail biting in organic than in conventional free-range pigs.
