Interesting Ode.  When treating horses for EPM, we initially started with the 
highest ppm we could make.  The horses had downturns (the silver was killing 
the protozoa in massive amounts) and then leveled off but didn't quite fully 
recover.  We then changed to low-ppm CS and the horses immediately went through 
another downturn.  They never stopped getting CS at any point, and they were 
all getting two cups twice a day at feeding time.  Left me a little confused 
but pretty convinced that low-ppm was the way to go.  Hmmmmmmmm -- any 
thoughts?     MA
