White Muscle Disease
Also known as Selenium/Vitamin E deficiency, or nutritional muscular dystrophy, it is caused by a low level of Selenium/Vitamin E (<1.1 ppm) in the blood resulting from a dietary deficiency due to low soil concentrations.
Aetiology
WMD is most commonly seen in offspring of animals grazed on pasture or fed crops grown from soil which is deficient in selenium. Cattle are normally affected between birth and 4 months of age, with sheep seen to be affected between 3 and 8 weeks of age, it has also been seen in foals up to 12 months of age.
