dc.description.abstract Although there is abundant scientific information regarding vitamin E and selenium deficiency disease in domestic poultry, there is only scant information on exotic species, such as ratites. Several necropsy cases involving ostriches, emus and rheas were presented to the Oregon State University Veterinary Diagnostic Laboratory with gross and/or histologic lesions of degenerative myopathy. Investigation of these cases led to determination of tissue levels of vitamin E and selenium and to determination of the dietary levels of these same substances. A small group of emus with a post-mortem diagnosis of degenerative myopathy was supplemented with dietary vitamin E with excellent clinical results. This success prompted a survey of vitamin E and selenium levels in blood and feed from clinically normal ratites. This information was then used to make recommendations for dietary levels of vitamin E and selenium in ratite formulated diets. Since overzealous supplementation can result in selenium toxicosis in birds, a safe, but effective level of dietary selenium and vitamin E is necessary for optimal propagation of the various ratites species. en_US
