The barren ewe problem can be eliminated by a single dose of from 1 to 25mg Se given one month prior to joining with the rams.

The infertility results from embryonic mortality between three and four weeks post-conception.

Under the conditions of the trial neither the antioxidant, Santoquin, nor the Vitamin E preparation, Rovimix E, prevented selenium-responsive infertility.
