Nutrition

Today I went to help Sam out. So in the meantime, while mucking out stalls, she taught me about nutrition, as far as horses go... Here's what I got:

*First cutting, super rich, goes to cattle
*Alfalfa, stem less nutrition, leaf more healthy
*California gets some of the worst hay
*Grass hay needs supplementing for calcium
*Grass takes super long to grow and can run out in the off season
*2::1 ratio, 2 calcium for every 1 phosphorus??
*Pasture is mostly made up of water
*Pasture horses need supplementing for whatever the soil is lacking
*Pasture horses eat 12hrs a day!
*Grains should be fed only 10% of total diet
*They should also be fed in increments to prevent colic
*Corn-super high in energy

That's mostly it, there's more but it's hard to remember it all, lol.
