How does lysine affect protein requirements/usage?  What effect would there be
from feeding a ration deficient in lysine but otherwise with more than necessary
protein?  Would not having enough lysine mean that not all of the protein is
metobalized?  (Can you tell yet that I have no idea how metabolism works?)

Relatively speaking, 140% of requirements isn't way out of line---it's
excessive, but not as bad as some rations I've analyzed that were 400-500%
of requirements.  But, it's still more than Roo really requires.  The thing
about protein is that it doesn't have a toxic level like some nutrients do,
ie selenium, vitamin A or copper.  It's just that the further you go beyond
requirements, the more you're going to have to contend with issues like
metabolic waste heat, increased urine production and water requirements.
None of them lethal, just not ideal for distance horses.
