Re: Selenium

Hi Sarah,

I've been told for years that my area was in deficite, but when we gave
even the recommended dosage, the hooves went to pot.  Now I don't dose at
all. 

Then in this month's issue of Equus, I see that we fall on the line,
(Chattanooga, TN)  On one side of the line said "Low", the other side
said "Dangerously High".  Think I'll just let it ride.
