[RC] anemic horse - Susan E. Garlinghouse, DVM

I agree with Dr. Kellon's comments, I don't find your results to be anything
worrisome or unusual, and I would certainly not call this horse anemic.
Long before I would go pursuing additional exotic diagnostics or even
treatment, I would exercise the horse for twenty minutes to contract the
spleen and pull the sample then----as Eleanor commented, a truly anemic
horse will still be low ranges.  A healthy horse's hematocrit will increase
at least into the 50's, usually low or mid 60's.  Eleanor has more exposure
to race horses than I do, so I wouldn't be surprised if she sees race horses
with hematocrits approaching 70.

I also agree that supplementing with additional dietary iron is not a good
idea.  Anemia due to dietary iron deficiency is pretty much unheard of in
horses, even those on a pretty crummy diet.  You're a lot more likely to
cause problems, rather than solve them, by adding blood builder supplements.
If nothing else, it's an excellent way to interfere with the immune system's
normal defense mechanism of sequestering iron to slow the replication of
invading pathogens.  Overwhelm that pathway by inundating the body with
dietary iron that it otherwise doesn't need and the only species you're
assisting are the infective ones.

The rest of the CBC looks to me like your horse is presenting an overall
very healthy profile.  I wouldn't be concerned about the borderline low
lymphocytes.  The only thing I would suggest would be bumping up his
selenium, as general consensus among endurance vets is that over .20 ppm is
better, and somewhere in the neighborhood of .250 ideal.

JMO.
