콘크리트우상을 지닌 후리스톨이 젖소의 혈액화학적 성상 및 발굽질환의 임상 형태병리에 미치는 영향

During the period from june 1994 to february 1995 influence of free stall with concrete floor on profile of blood chemistry and clinico-morphopathogenesis of foot disease on 266 cows were studied. The results obtained as follow. 1. No differences between value of blood chemistry in normal and lame cows with foot disease were observed. 2. 20.7% of the cows were clinically lame. 3. Prevalence of clinical digital disorders were investigated: hyperplasia interdigitalis(45.8%), pododermatitis circumscripta(22.4%), dermatitis interdigitalis(9.4%), erosio ungulae(5.9%), phlegmona interdigitalis(3.5%), pododermatitis septica traumatica(3.5%), dermatitis digitalis(2.4%), white line disease(2.4%), pododermatitis aseptica diffusa(2.4%), dermatitis verrucosa(1.2%), fissura ungulae(1.2%) 4. Most claw lesions were located on lateral hindclaws and interdigital space of hindclaws.
