Effect of Dietary Selenium on Incidence of Nutritional Encephalomalacia in Chicks. ∗

Abstract

Summary

Addition of 0.13 ppm of selenium as sodium selenite to a semisynthetic diet containing 4% corn oil freed of tocopherol reduced the incidence of encephalomalacia. On the other hand, when 8% corn oil was fed, selenium in levels up to 1.56 ppm had no effect on the proportion of chicks with encephalomalacia. Growth was not affected by addition of selenium.
