Selenium and sheep

Asked January 25, 2018, 4:46 PM EST

We have been raising hair sheep for about 8 years. Usually we have between 3 and 12 ewes. We have never given selenium injections. This year for the first time we have a lamb that seems to have white muscle disease. Hunched, deteriorating muscles, alert, eats, and seems to poop well. Mother is older and does not produce much milk so we have been supplementing with lamb formula. How common is white muscle disease here in the Willamette Valley? Do most sheep growers inject selenium? Does anyone add selenium to their pastures?

Selenium deficiency is EXTREMELY common in all of western Oregon. Nearly all sheep and goat producers inject their lambs/kids with BoSe (1 mL) soon after birth. We are fortunate in OR to be able to utilize Selecote Ultra in our fertilizer mix for our pastures. This is relatively inexpensive and very effective but does need to be done every year.
