We carried out the research on those clinical charts to obtain the understanding of those tendencies. As result, of research; 1) there were high occurrence rates of foot rot or arthritis, 2) disease of hooves occurred in high rate, especially during June to September, 3) pelvic limbs' disease occurred at higher rate than fore one, but in arthritis the result was reserved, 4) most of those cows got well, except for cows that had not be easily able to stand, not been treated locally or had four injured limbs. These results indicate that limbs' problem occurs not a few as for Japanese Black and Japanese Short Horn breeding cows, It is considered that earlier detection and treatment, regular observation of hooves and hoofs trimmings would be important to prevent for limbs' problem.
