A research group at the University of Tokyo Graduate School of Agricultural and Life Sciences, Department of Veterinary Medicine, and the Peco Veterinary Medical Center analyzed animal pathological autopsy records that had been accumulated since the Meiji period. We found that the number of cases was increasing.
According to the University of Tokyo, the research group analyzed animal pathological autopsy records from 1902 onwards that remain at the University of Tokyo Graduate School of Agricultural and Life Sciences, and investigated the transition of cases from the Meiji era to the Reiwa era.
その結果、1903～1914年の明治・大正期は犬（44.6％）と馬（34.8％）、1956～1969年の昭和の高度経済成長期は犬（62.9％）とネコ（17.3％）、2006～2020年の平成・令和期は犬（46.0％）、ネコ（26.1％）、エキゾチック動物（20.5％）の病理解剖が多かった。
Looking at the median ages of the animals that were autopsied, dogs were 2 years old during the Meiji/Taisho period, 3 years old during the Showa period, and 10 years old during the Heisei/Reiwa period, while cats were 2 years old during the Showa period and 10 years old during the Heisei/Reiwa period. aged with the passage of time.Cases of disease have plummeted in infections, including parasites, and tumors are on the rise.The research group believes that the improvement in veterinary medicine technology and the spread of vaccines and antiparasitic drugs have extended the lives of animals.
The analysis of animal pathological autopsy records from the 1900s is unprecedented not only in Japan but also in the world.It can be said that it is a valuable material for understanding the social background of each era and the progress of veterinary medicine in Japan.
