I did say this. I start with offering a quality first cut hay - free choice.
Then start on grain, which is a complete feed, 3qts, which is not much grain given we are talking of a Thoroughbred here, not a shetland.
In the weeks following up the grain to a scoop and a half which is 5qts and add alfalfa and or beet pulp IF necessary. At which time I'd introduce corn oil, BOSS and several herbs to the horses feed. If a few weeks down the road the horse appears to need a bit more I toss out second cut hay and continue the feed.
If slowly means a flake of hay and a handful of feed monday, a handful and a half tuesday, a handful and 3/4 wednesday etc... Then yes, I suppose I do move faster. However "luck" has not been with me, the feed schedule I have used and the way I have used it has worked for a few more than "luck" could play part in. People seem to have the poor illusion that it should take six months for a horse to pack on 150 pounds.
