My OTTB gelding has had trouble gaining weight (I assume even before I adopted him as he was quite thin at the rescue). He went through a stage of playing with his hay instead of eating it, then resuming eating hay and neglecting his feed. He had grown to dislike that particular feed's flavor, but we managed to find something he likes that has put some weight on him recently. This is his current feeding schedule:
AM - 2 scoops/4 quarts Purina Senior*
Daytime - grazing out in the pasture
PM - 2 scoops/4 quarts Purina Senior, 2 flakes of hay**
*We have him on the Senior because he actually eats it and it has a decent fat content. He was first on Ultium, but he grew to dislike the taste. Omolene just made him stupid hot.
**I'm not 100% sure what kind of hay the horses at the farm get, but I do know it's fairly high quality.
He is gaining weight slowly, but he will be under saddle in the next few weeks (I'm hoping) so I am somewhat worried about that weight gain just shedding off him from the work. I may look into supplements and other things to add to his diet to get and keep him at a healthy weight. Which is what I need you folks for.
What have you tried? Recommend? Swear by?
(He's a four year old Thoroughbred, by the way...putting that here on the end to keep it fresh in your heads)
