Causes of Exudative diathesis
All species of birds at all ages can be affected by exudative diathesis, which is produced by a Vitamin E and/or selenium deficiency in diet.
Special note
Selenium is involved in vitamin E metabolism. Selenium is involved in proper development of skin and muscles and is a mineral involved in coenzyme formation. There is a wide variability in the amount of selenium in soils which can influence the selenium content of grains and hence the diet.
See also Selenium deficiency; Vitamin E deficiency.
