| description | Organic animal husbandry has received a lot of criticism lately. The aim of this literature review was to examine if the rules and principles of organic pig farming give better or worse welfare in comparison to the conventional systems in Sweden. Health, physiology and behaviour have been used as indicators of welfare in this study. This is due to the importance of using more than one indicator in welfare assessments. Studies have shown that organic pigs have more remarks on joints when slaughtered, but these remarks can be reduced by vaccination against erysipelas. Respiratory diseases were significantly more common indoors. Different studies showed different results of which system that caused more liver damage. Mange was more common outdoors than indoors but can be treated when symptoms occur. The physiological parameters showed that pigs who lived outdoors were more stressed but also more stress resistant. Behavioural studies showed that pigs in enriched pens were calmer and showed more exploratory behaviour, thus one can assume that outdoor living pigs mostly are affected by natural positive stress. Stress caused by fluctuations in temperature can be taken care of by correctly designed huts and by giving the pigs access to mud bathing. Pigs outdoors have been proved to perform a greater repertoire of behaviour and less abnormal behavior than pigs indoors. It was difficult to see any difference in welfare between organic and conventional pigs outdoors but it seems reasonable that the most correct in an animal welfare ethical view is to keep pigs outdoors. |

Mycket kritik har riktats mot ekologisk djurhållning den senaste tiden. I denna litteraturstudie har det undersökts ifall regler och principer inom svensk ekologisk svinhållning ger sämre eller bättre välfärd än i konventionell svinhållning. Hälsa, fysiologi och beteende har här använts som indikatorer på välfärd då det är av stor vikt att använda ett brett spann av mått vid välfärdsmätningar. Studier har visat att de ekologiska grisarna har fler slaktanmärkningar på leder än de konventionella men att dessa anmärkningar kan minskas till samma nivå om man vaccinerar mot rödsjuka. Lungsjukdomar fanns i betydligt högre utsträckning inomhus. Vad gällde leverskador gav olika studier olika resultat. Skabb var vanligare utomhus men kan åtgärdas vid symptom. De fysiologiska parametrarna visade att ekologiska djur var mer stressade men samtidigt mer stresståliga. Beteendestudier visade att djur i berikad miljö var lugnare och mer utforskande. Ur detta kan troligen slutsatsen dras att utegrisarna mest påverkas av naturlig - positiv- stress. Stress orsakad av temperaturväxlingar kan åtgärdas med välutformade hyddor och tillgång till gyttjebad. Utegrisar har visats ha möjlighet att utföra en mycket större repertoar av beteenden och de uppvisar även färre onormala beteenden. Det var svårt att se någon skillnad mellan ekologiska och konventionella utegrisar. Det mest välfärdsriktiga verkar därmed vara att hålla svin ute, ekologiskt eller inte.
