A number of experiments were conducted to determine whether surface coatings on pellets, season of treatment, or age of sheep affected the efficacy of intraruminal selenium pellets, as measured by selenium status of the recipient sheep. Also, comparisons were made between pellets and oral drenches of sodium selenate, and between three brands of commercially available pellets. Plasma selenium concentration reached a maximum within 2 weeks of administration of either pellets or oral drenches. Thereafter concentrations declined rapidly, but with all three brands of commercial pellet examined, sheep would have been protected from white muscle disease for at least one year. There were, however, differences between brands; one brand of pellet maintained the sheep at a higher selenium status than the other two. Surface coating, season of treatment, and age of sheep had only minor effects on pellet efficacy.

In this study, the selenium content of forage from farms in northern Ontario where nutritional muscular disease is very severe was less than 0.1 p.p.m. Variations in the sulphur content of forage did not appear to affect the occurrence of the disease. A combination of vitamin E and selenium given to pregnant dams or directly to calves was completely effective in preventing the disease. Data on the selenium content of the hair of dams and calves are presented. Calves, sick or dead from white muscle disease, were born to cows with low selenium content of the hair (range 0.06–0.23 p.p.m.). No white muscle disease was observed in calves from dams with selenium content of the hair above 0.25 p.p.m. Selenium content of the hair was generally greater in the selenium-treated calves or those born to selenium-treated dams. It seems probable that the selenium content of hair may be a helpful factor in diagnosing white muscle disease.
