I know he is half Clydes, but I do not know his other cross.
I've had him on hay, some pasture, approx. 9-10 lbs spaced out through the day of ACV, Oil, Rice Bran, Beet Pulp, Oats and Alfalfa Pellets. That has put weight on my thin Saddlebred rescue that no other mix would as well, BUT It caused my formerly well conditioned Arab mare to loose weight. . .so it will not work for them all.
