The Excretion of Selenium by Rats on a Seleniferous Wheat Ration

Abstract
The greater portion of the selenium absorbed by rats from naturally occurring seleniferous wheat was excreted when the animal was transferred to a non-seleniferous stock ration. Some of the selenium was eliminated very slowly and appeared to be bound by the body tissues but the greater portion of the selenium appeared to be eliminated within 2 weeks. Young rats appeared to store more selenium in the body tissues other than liver than old rats. Storage in the livers appeared to be similar. Feeding of the toxic ration for only 4 weeks had a depressing effect upon the body weight of both young and adult rats.
