normal horses and substrates

["Beth Glace" <lb@nismat.org>]

Hey Tom,
Is horse metabolism so different here  from rodent/human metabolism?  
A person at rest, will often use entirely fats for energy.  At a 
walk, in a trained individual, I still see them using almost entirely 
fats.  At a slow jog mostly fats [again this in a trained individual, 
an unfit person will be at near max and totally reliant upon carbs at 
a slow jog.]  What are the RER values in horses during treadmill 
exercise at sumbaximal workloads?  This info must be out there 
somewhere, any one know?  Would be a fairly easy study if the lab has 
a treadmill and metabolic cart.  Now, Tom,  carb 
supplementation should still prolong their ability to exercise, don't 
get upset here.

<<When you say NORMAL horse, you're talking about a horse standing
]still. Fed 
lightly on carbs. with fasting level blood glucose. The laboratory
animal. A C Major chord. When the horse goes to work, the 7ths and the
9ths come into play and it's a far more complex progression of
harmonies. >>
