The erosion, crack, swelling of hind heels, the conditions of hind leg and standing of 188 sows in three farms in Chiba prefecture were investigated on May 2007. Four heels with erosion were examined using histopathologic technique. As a result, the prevalence rates of erosion, clack and swelling of hind heel were 73.4%, 48.7% and 78.8%, respectively. The score of heel lesion gradually increased with sow aging. The prevalence rates of the outside heel and inside heel were 60.1% and 8.4%, respectively. The relationship between standing and heel lesion was not found. The lesion was diagnosed as hyperkeratosis by histopathologic examination.
