Introduction: In December 2011 we reported an increased incidence of polymelia (notomelia, cephalomelia and pygomelia) in Angus cattle which appeared to be transmitted as a heritable disorder. Here we present an update on our more recent work in this heritable syndrome.

Congenital Contractural Arachnodactyly

Dr Laurence Denholm, BVSc(Hons) DipAgSc LLB(Hons) PhD (Cornell)

Introduction: Congenital contractural arachnodactyly (CA), also known as “fawn calf” syndrome (FCS), is a heritable disease of newborn Angus and Angus-derived cattle caused by an error in the DNA genetic code transmitted from parents to their progeny

Oculocutaneous Hypopigmentation (OH)

Introduction: Oculocutaneous Hypopigmentation (OH) is a non-lethal genetic condition and is largely cosmetic in nature. Affected calves have eyes with irises that are pale blue around the pupil with a tan periphery. Their hair coats have a slightly bleached color. While some affected calves have sensitivity to light, they are believed to be otherwise normal functionally and physiologically.
