Just curious on your guys' opinions. I've fed my stud colt, now 2 years old, pretty much the same thing since he was born. He's kept in a dirt pasture with four cows. He gets 1 - four quart scoop of sweet feed once a day (Usually between noon and 4 o'clock) then is turned out in the yard to graze for an hour or two, then is put back into the pasture with the cows and they all share a square bale of hay. I've had no problems keeping weight on him and he has good muscle mass for a two year old. They also get a round bale of hay a month through the winter. Anyway I just bought a 6 six year old mare that's bred and has been on grass pasture, she will have her own stall and seperate turn out where she can graze as she pleases and I was thinking of doing the same for my boy but I'm worried about the change from him going to eating what he gets about 4/5 hours a day to being able to eat nice green grass all day long. I realize horses were pretty much made to graze all day but I feel like it's a pretty drastic change - any opinions on this? By the way he's a 2 year old 13.2 Haflinger/Paso/Paint
