[Familial occurrence of a congenital defect of the keratinisation of the skin in German Angus calves].
Congenital dysfunction of the keratinisation of the epithelium was diagnosed in two female German Angus calves born on the same farm. The relationship coefficient between the two affected Angus calves was 34.38%. The clinical findings were similar to ichthyosis congenita as the alterations of the skin were present at birth and the levels of zinc in the blood were not decreased. However, parakeratosis could not be completely excluded as skin alterations were partly parakeratotic. On account of the close relationship between the two affected calves a genetic cause is likely for the present cases.
