The occurrence of myopathy in vitamin-E-deficient ducklings, which is used for the determination of the degree of vitamin E deficiency, is depending on the selenium content of the diet. The selenium content of a semi-synthetic diet and its constituents was determined by neutron activation analysis, which showed to be an adequately sensitive and precise method of analysis for selenium. The casein compound was the main source of the selenium in the diet. Myopathy occurred with diets containing about 50 ppb Se; diets containing about 100 ppb Se failed to induce any signs of myopathy.
用于确定维生素E缺乏程度的维生素E缺乏雏鸭会出现肌病，这取决于日粮中的硒含量。通过中子活化分析测定了半合成日粮及其成分中的硒含量，结果表明这是一种对硒具有足够灵敏度和精确度的分析方法。酪蛋白化合物是日粮中硒的主要来源。日粮含约50 ppb硒时会出现肌病；含约100 ppb硒的日粮未引发任何肌病迹象。
