I have a very easy keeper. Right now he is getting about a pound of Gro' and Win by Buckeye (its a ration balancer) once a day, a small hole hay net full of brome/native grass hay twice a day (I don't know the exact weight) and he has access to a salt block and the red mineral block.
He is 17, and at this moment in time is not being worked heavily. He also is not turned out on pasture at the moment. He has a decent sized turn-out though.
I want to know if this diet is providing sufficient vitamins and minerals. I may talk to the BO and see if they would be willing to test the hay. The only problem is.. we have hay from several different areas. It isn't all the same..
