In our previous paper (1984) we reported that population size of Kiso Horses had recently decreased. This indicated that intense inbreeding had taken place within the population. This report was carried out to calculate the coefficient of inbreeding in Kiso Horses. Used horses, 9 males and 79 females, were registered from 1969 to 1983 and their ancestors could be followed to the third generation of their pedigrees. The coefficient of inbreeding was calculated with Wright's formula. The average coefficients of inbreeding of males and females were 0.095 and 0.060 respectively, indicating high degree of inbreeding (Table 2). Changes in the average coefficient of inbreeding during the last ten years showed the average coefficient of inbreeding had increased with advancing years (Fig. 2). These results show that Kiso Horse breeders are needed to avoid inbreeding as much as possible.
