Chondrodysplastic dwarfism with short limbs, gait abnormality and ateleiosis occurred in 21 Japanese brown calves in Kumamoto Prefecture from Sep, 1983 to Feb, 1988. The disorders were confined to the long bones of the limbs and were characterized by shortening and epiphyseal deformation caused by chondrodysplasia of the epiphyseal growth cartilage. Phenotypically, the dwarfism seen in these calves differed from all other forms reported to date. The circumstances in the occurrence and pedigree study strongly indicated the likelihood that the abnormality represents a recessive character.
