title: Soft coal fly ash as a source of selenium in unpelleted sheep rations.
abstract: Soft coal fly ash has been found to be a source of selenium when included in the rations of cows and hogs. In the work reported, a ration including 10% by weight of soft coal fly ash was fed to sheep for 135 days. Selenium levels in blood and tissues of the animals fed the fly ash ration increased significantly above the control sheep. No adverse clinical signs or lesions were observed in the animals on either treatment.
