RE: [RC] Where is selenium high/low? - Susan E. Garlinghouse, DVM
We know there are other failures in GI uptake when the
system is starved of that substrate, thus many of the developments in
parenteral nutrition under extreme conditions.

>Could you give an
example of that please?
Extreme protein deficiency = loss of GI transport proteins =
inability to absorb amino acids unless/until supplemented via IV routes.
I’d be happy to find you exact references and a discussion of it, but it
will take me a little while to go find them. I’m not quite sure
where my undergrad nutrition texts even are anymore, which is where the original
discussions were, if memory serves.

It hasn’t been very much of a surprise to any of the equine
vets I’ve talked to on both coasts, although as with Heidi, my practice
was certainly not limited to endurance horses. Much higher percentage of
eventers, hunter/jumpers and dressage horses. I didn’t do race
track practice, but its pretty common practice on the tracks as well, according
to colleagues that do track work. You know what they say, “What
works is real.”
