I would not feed anything high sugar/starch. Tc senior is good being at 11% NSC extra beet pulp won't hurt it's fiber. As long as it doesn't have molasses in it.
Forage based diets are best ,horses don't need grain or sugar in diet.
Pony looks good I'd say she's a bit fat. Looks pretty hairy yet for being almost June. I'd be testing her for Cushing's.
My horses are pretty much shed out just a little winter coat left yet, on belly an legs.
I’ve written out all the different pellets and the beet pulp is the lowest fiber option, however the teff grass is only 6% more with almost double the amount of protein and triple the amount of fat. Would the teff grass be a better option?
Everything else has 30%+ fiber.
Last week was the first warm stretch we’ve had so far this year, Easter weekend we got about two feet of snow to give you an idea of how our “spring” is going this year. Lol. Didn’t help she came from the county where they still had snow when I picked her up! She’s been shedding like crazy since the weather has finally changed, I’ll keep an eye on her in the coming years though and ask my vet what he thinks.
She is plump because she started to lose weight when I brought her home and started exercising her. I increased her food, but I think most of the weight loss was from transitioning to a new place. I’ve already started feeding her less again but have been focusing more on brushing her out lately than exercising. Trying to find a balance for her, haha!
Triple Crown Senior is a great feed that can be used for these older horses unable to eat forage effectively. I would almost stop feeding the beet pulp, and feed more of the Senior pellets. If she were my horse, I would be hesitant to let her have access to hay at all, or even long grass, just in case she tries to swallow it and chokes.
I think your mare looks really good, given her being a senior and lacking teeth. I would get her tested for Cushing's as well. There is a user on here (@walkinthewalk) that recommended feeding L-Citrulline, and feeds it to her IR/Cushing's horse. There isn't much research on its benefits in horses, but many in humans. If you want to check on my thread on 'Strengthening a Horse', there is more that she typed out there in detail.
I give you credit for taking so much care with feeding your senior mare, she looks like such a good horse for your son.
She doesn’t have access to hay here, this is what has been told to me from the previous owner. I mentioned that to the PO as well since I’ve had problems with choke in senior horses I’ve owned in the past. Right now she is the only horse on the property until I bring my mare who does eat hay but only at night in her own stall. We have 5 acres that we keep mowed and rotated, the property owner is very particular about pasture maintenance.
