My Anglo Arab is not a hard keeper. He's an impossible keeper.
Beau is a former racer and grade gelding, he looks like an Anglo Arab but who knows. He was a champion jumper for years until his owner decided she wanted a car instead of a horse. She sold him to his farrier, and then things started to go downhill. Beau lost 250lbs while in the pasture with the farrier's QH. He didn't understand why the guy was taking it so hard, so he put him up for sale and we bought him. He was in pretty bad condition when we got him, but still jumped just fine on a longe. He gained a decent amount of weight over the next few years, always about 100lbs underweight no matter what we did. Two or three years ago, he choked because he was so nervous about something. He just does that, has nervous fits. He had to wait a full two days for the vet because the vet was involved with a mare who was colicking and about to foal and both were about to die (they turned out fine). He was about 75lbs underweight at the time he choked. He dropped to near death because of the stress of the choke. We changed his diet to mush. A year later, he did it again. Added more water to the food. Again, he dropped to near death weight.
Now, year and a half or two years later, he's back to a decent weight, but still about 100lbs under. At least no one is calling the humane society anymore telling them that we are starving and neglecting our horse. He's in a field where everyone else has a grass belly (great rain this summer) and we're having to cut back on feed a bit.
He gets a full bucket of Triple Crown Senior (supplemented with Mare and Foal when his weight gets really bad, the senior also has beet pulp in it) watered down to a mush, corn oil, raspberry leaf (to calm him down, that stuff really works), and two flakes of alfalfa every day, plus a round bale in the pasture and free grass. All the food is spaced out to twice a day except for the pasture stuff. He will not eat weight builders, I've tried every one on the market I think. This routine has kept him out of the danger zone, but he still is underweight. His ribs are getting better, but you can still see his spine and tail base. His face is also very bony.
Vet has checked him out as a-ok health wise, other than being an impossible keeper. He has had sand clear, and gets a special wormer.
Any suggestions? Is there anything I can do that I might not have thought of yet? If I left out something, please ask me and I'll add it!
The pic of him in my "barn" is when he was at a good weight. His face is much older looking now. He's only 18.
