Why would you think anyone would be judgemental and harsh with you? You are doing the best you can for your horse. Who would stand in judgement of you for that?!
I also hav a TB who used to be so skinny his body score was a 2 when we bought him. He is now so fat that people think he's an appendix QH instead of an OTTB.
There is no right or wrong TB diet...you just have to work with it till you find one that works for your horse.
The diet Beau was on that made him fat is:
Free choice hay
2.5 lbs Strategy
1 lb. Alfalfa cubes
2 scoops cool calories
SmartDigest probiotic supplement
Now that it is spring/summer: 6 hours grass time daily
And I also agree with giving your horse Continuex or Strongid for a few months at least....they are continous wormers.
Our Beau is now too fat, he's got a slight crease in his back...so we are cutting out the cool calories to see if that helps. If not, we will cut back on the alfalfa, then the grain. Grass/hay is best for horse digestion, so if something has got to be cut, it's the alfalfa, grain or weight supplement
I HIGHLY reccomend a probiotic supplement for hard keepers.
