An environmental survey was made based on data from postmortem examinations of 273 cases of perinatal disease in the Hidaka district. The results are summarized as follows.1. Perinatal diseases occurred throughout the Hidaka district and no causative factor that could be considered a regional specificity was recognized.2. Most of the infectious diseases were due to indigenous bacteria and occurred more frequently on farms under overcrowded rearing conditions and along rivers.3. On old farms, the incidence of diseases such as myolysis was high.These results show that breeding environmental factors have great influence on the occurrence of perinatal diseases.To prevent perinatal diseases, it is necessary to limit the number of horses according to local conditions and the size of each farm.It may also be essential to take both health care and improvement of the breeding environment into consideration.
