Nutritional muscular dystrophy
Nutritional muscular dystrophy (also called nutritional myopathy or white muscle disease) is a muscle disease of lambs, calves, and foals and adult horses due to deficiency in selenium and/or vitamin E.
The condition is observed in all breeds and sexes of lambs, from birth to three month of age.〔Jensen, Rue & Brinton L. (1982) ''Diseases of Sheep'' Philadelphia, Lea & Febiger ISBN 0-8121-0836-1 p. 86-88.〕 Its frequency increases with upgrading of sheep breed for increased muscling, especially in areas with selenium deficiency in soils.
In dairy breeds, the occurs in calves from some days after birth until four months of age. 〔Gustav Rosenberger, ''Krankheiten des Rindes'', Verlag Paul Parey, Berlin, ISBN 3-489-61716-9. p. 912-913〕 But, in rustic breeds or beef cattle, heifers and young steers up to 12 months can also be affected.
== Clinical symptoms ==
The most usual form involves skeletal muscles, especially in the back. The animal is weak when it stands up, and has an awkward gait. Animals tend not stay up for more than a few minutes. When in recumbency, the animals are normal, and have a good appetite.
