Sorry, I cant let this go even though the calc doesn't have any endurance
relation, blame it on being an engineer.

Pasture forages can range considerably in moisure content. But, as an
example, if a particular pasture has a dry matter content of 23% (77%
moisture), then the same 1000 lb horse will need to graze 26.6 lbs of
pasture to meet his recommended needs:

[(1000 lb horse * 1.5% DM feed per lb of horse) * (77% moisture content
+ 100% base)] = 26.6 lbs of pasture needed.
-------------------------------end included-------------------------

The correct calculation would be:
[(1000 lb horse * 1.5% DM feed per lb of horse) / 23% DM content) =
a whopping 65.2 lbs of pasture.

>>The water in the grass will
quickly be absorbed by the small intestine (1/2 hour or so after
ingesting), so in turn, Sugar Lips will take fewer trips to the watering
hole. >>

and since water weighs something like 7 lbs per gallon, this just means
65*77%/7 or 7 gallons less water the horse
has to drink.
