[RC] Help for anemic horse - Eleanor Kellon"Blood work to evaluate cell populations should never be taken after exercise as the spleen can release up to 30% of the normal red cell number. "
====================
Yes, but that's the point. To explain further, a very fit and quiet horse can run a low PCV/hematocrit at rest. This is because their body is more efficient in generating energy and requires less oxygen. It's particularly common in Arabians because of their higher oxidative capacity than other breeds. Ten to 15 minutes of brisk trotting will typically bring the hematocrit up to about 45 to 55%. At a gallop, it will go as high as 65 to 70%. If the horse is truly anemic, you'll be lucky to get comfortably into the normal resting range because blood cell reserve is low.
