Does anyone have information on a vitamin B1 defficiency? I have researched it a little... what I'm trying to find out is where horses naturally get most of their B1 vitamin... I know a defficiency can result in a horse that is nervous, anxious, or stressed and tense. I am assuming that most of this vitamin comes from grass, and one article stated that horses with a lack of pasture will have a defficiency, however I can't seem to find an exact answer on where the B1 comes from. Thanks!
I know you can buy it as a supplement, but I'm looking for where they naturally get it.. thanks!
