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.

摘要

本流行病学研究基于挪威东南部70个猪群1984年至1986年的个体健康记录。对于大多数记录的疾病,每窝仔猪的发病率低于1%。大多数疾病记录涉及6种常见病症;MMA综合征、乳腺炎、子宫炎、新生仔猪腹泻、关节炎和阴囊疝。几种疾病的发病率呈现出季节性效应。在一项群体研究中,MMA综合征约17.5%的发病率似乎是该疾病有记录以来最高的。
