Fourteen cases of chondrodysplasia in cattle are described. Epidemiological and clinical data were obtained from filed necropsy protocols. A histological study of the lesions was performed on long and skull base bones. Eleven cases of chondrodysplasia Telemark type and three Bulldog (Dexter) type were observed. Thirteen out of 14 cases occurred in Jersey cattle and one in Shorthorn. It was concluded that the gene carrier of chondrodysplasia is present in the Jersey population of the region, and breeding measures such as the use of bulls from other regions and/or progeny testing or identification of undesirable genes using molecular techniques should help reduce the occurrence of these cases in the Jersey population of the region. |
