I thought this was sooooooo cool,
Well according to equus magazine

giving your horses acess to grain anytime they want can actually be HEALTHIER for them! And that once they figure out there will always be grain for them to eat at anytime they will not gorge themselves with it. They did a test and they slowly started giving a certain amount of geldings a certain amount of grain...then they kept giving them more and more grain over a period of time...at first the horses would gorge themselves, but after about 3 weeks the geldings were on free-choice and they were only eating as much as they were before they started the experiment!!!! They also said that it is really bad for people to buy grain dense with nutreints and stuff just so that they can feed less, because the nutreints and other things (haha whoops, bad memory I can't remember the name they said!) is what usually caused laminitis,colic and other food sickness's.
Did anyone else read this article? I thought it was great! But sadly we can't start feeding free choice at our barn because its a boarding barn, and that most of the horses get certain supplements that others can't have.
I don't want to hear a big arguement about this, it was tested, that's what it said in the magazine,period.

I just thought I would share, its useful information anyway!!!
