Re: Selenium deficient

Hi Beth,

Nice to hear from you anyway!

I can't tell you why, but the bottom line reason is the diet was low enough in selenium to trigger an obvious deficiency disease in the foals. Could be forage coming from a different reason or change in soil selenium levels from different fertilizer or different water supply. You should be fine after about a month of selenium yeast supplementation but check her whole blood selenium level to be sure. Check vitamin E too.

This is a good example of how you can often  "get away with" nutrient deficiencies and imbalances in healthy adults but increasing age and other stresses, like pregnancy, can tip them over the edge into a full blown classical deficiency. Less dramatic consequences may include unexplained anemia, muscle/nerve signs, poor immunity, low thyroid function, hoof and coat issues.
