Outline of Final Research Achievements

When domestic animal infectious diseases occur, a large amount of slaked lime is sprinkled on cattle sheds and the surrounding for disinfection and prevention. In this study, we verified bactericidal effect of slaked lime in vitro experiment and investigated the influence on ecosystem (mainly microorganism) by sprinkling powder slaked lime of various density on the field soil. In vitro experiment, disinfection by slaked lime was shown to be very effective for prevention of domestic animal infectious diseases. Field experiment showed that sprinkling slaked lime did not influence on the number of living microorganism, but pH and calcium concentration of the soil were remaining high even after a long period elapse.
