[Selenium content in the internal organs, musculature and blood of broiler chickens]

Experiments were carried out to establish the presence of selenium in broiler birds at different age, that had been given prophylactically selenium preparations. At the single application of such preparations selenium was found to drop in the liver, kidneys, brain, and blood, and to rise in the breast and femoral muscles. By the end of the fattening period highest was the level of selenium in the organs and tissues with the intake of sodium selenite in the drinking water; it was lowest at the injection of sodium selenite in effective amounts.
