Abstract

The present epidemiological study is based on individual health records from 1984 to 1986 in 70 pig herds in the south-eastern part of Norway. For most of the recorded diseases, the incidence rate was less than 1 % per farrowing. The majority of disease recordings concerned 6 frequently-occurring conditions; the MMA-syndrome, mastitis, metritis, neonatal diarhoea, arthritis and scrotal hernia. A seasonal effect on the incidence rate was shown for several diseases. The incidence rate for the MMA-syndrome of about 17.5 % seems to be of the highest recorded for this disease in a population study.

Sammendrag

Den foreliggende epidemiologiske undersøkelsen bygger på individuelle sjukdomsregistreringer fra 70 svinebesetninger i Hedmark. De fleste sjukdommene hadde en insidens på mindre enn 1 %, mens hovedtyngden av registreringene var forårsaket av 6 hyppige sjukdommer; MMA-syndromet, mastitt, metritt, spedgrisdiare, leddbetennelse og pungbrokk. De ble påvist en årstidseffekt på insidensen av flere sjukdommer. MMA-syndromet hadde en incidens på 17,5 %, som er den høyeste rapporterte insidensen for denne sjukdommen i et populasjonsstudium.
