RE: [RC] where is selenium high/low? - Susan E. Garlinghouse, DVM

But, even then it’s not written in stone. In some areas, one field
can have virtually lethal levels, and much different a mile away. Most
hay growers have a pretty reasonable handle on it, but getting your forage tested
is always the gold standard, especially if you’re not exactly sure where
a batch of hay might have been grown.
My experience with 2-year-old fillies (and colts) is that they
are born felons whose sole purpose in life is to eat other horse’s tails
while pondering new ways to drive you buggy. Mine were never deficient in
anything while they were doing it, and they all grew out of it after I
explained to them what I was going to do with this roll of duct tape. She’s
probably not actually eating the hair she’s chewed off, but I doubt it’s
a major gastrointestinal issue. If her imminent future is in doubt, you
and the shovel you’re chasing her with is probably a greater threat than
the ingested hair. <g>

Does
anyone know of a map that shows areas where selenium is high or low? I
remember hearing something about selenium levels in our area, but can’t
remember which way. We’re in southeastern Colorado, near Wet
Mountains, getting hay from Westcliffe, Salida and Pueblo.
On
a related note, could low selenium cause a 2 year old filly to want to eat
every horse tail in sight? This filly ate about 3 feet of tail off of 3
horses in less than a week. So I’m worried about all the hair in her
system, as well as what she might be missing? Any ideas?
Thanks!
