Re: Re: Re: water weight

["Michelle Rowe" <michrowe@frontier.net>]

regarding how much "fuel" the horses body has in storage (from "Energy and
the Performance Horse"):

muscle stores 1,400-2,800 g of triglyceride
adipose stores 40,000 g of triglyceride
muscle stores 3,150-4,095 g of glycogen
liver stores 90-220 g of glycogen

My calculation of lbs. of glycogen used per hour amounts to approx. 4,000
grams per hour of glycogen used.  I do not know if the above figures
represent the average pasture potatoe or a horse that has been trained and
should be storing more energy as a result of that training.  However, if my
previously supplied, questionable numbers are correct, the horse can only
store enough energy in fat and glycogen to carry it about 12 hours.
