| Abstract: | In 11 German Holstein cattle with black and white or red and white coat colour short tails could be observed. All affected animals were born in different farms. A clinical examination could not reveal further congenital anomalies of other organs. The parents of the affected animals showed no abnormalities of the tail. The pedigree data showed that all short tailed animals were related with each other and this fact provides evidence that brachyury is an inherited congenital anomaly. The coefficients of relationships were between 0.20 and 25%. The pedigree indicated a monogenic or oligogenic autosomal recessive inheritance. Environmental factors causing short tails in these animals were not obvious. |
