Congenital erythropoietic protoporphyria in a Limousin calf.
Bovine congenital erythropoietic protoporphyria is an uncommon genetic defect in Limousin and Blonde d'Aquitaine cattle that is characterized by severe photosensitization. Clinical signs include intense pruritus and exudative dermatitis involving the face, pinnae, and dorsal aspect of the thorax. Affected cattle have hematologic and serum biochemical values within reference ranges, and their teeth are normochromic. Definitive diagnosis of bovine congenital erythropoietic protoporphyria is accomplished by genetic testing. Affected cattle should be sent to a terminal market.
