Effectiveness of Selenium in Prevention of Nutritional Muscular-Dystrophy in the Chick.

Abstract
Whereas supplementation of a dystrophy-producing diet of severely vitamin E-depleted chicks with either 2.5 mg of d-alpha-tocopheryl acetate or 1.0 mg of selenium as sodium selenite per kg of diet alone had no effect upon dystrophy, supplementation with these amounts of selenium and vitamin E together completely prevented muscular dystrophy. These results indicate, therefore, that both selenium and vitamin E are concerned in prevention of nutritional muscular dystrophy in the chick.
