Viable hypotrichosis in a Jersey calf

Abstract

Various degrees of congenital hairlessness have been seen in cattle, and the literature on this subject has been reviewed by Hutt and Saunders (1953), who have proposed a classification of five categories. Semi-hairlessness in grade Hereford cattle in Queensland has been described by Young (1953). Our paper describes a case of congenital hairlessness in a Jersey calf which we believe to belong to the class "viable hypotrichosis" of Hutt and Saunders.
