Is This to Much Feed for my Horse?

Hello,
Today I weighed my horses feed because I was curious how much feed she was now. I was Surprised. My Horse is a 30 thoroughbred/appy, with cushings disease. She was severely underweight coming out of last winter due to many factors that have now been taken care of. She is now 950lbs when the vet came out last week, also surprised that that. She is turned out 24/7 on a 1 acre dirt paddock with my Gelding, there is little to no grass. She also can not chew hay anymore. She gets about

She is fed twice a day, but the food last her 4-5 hours.
25.5 lbs of hay stretcher wetted aday.
2.6 lbs of Sentinel Pro. LS wetted aday
4 lbs of Dynasty XT Pro wetted aday.

That a grand total of 32 lbs a day of food, which seems like a lot.
Since she's up to weight I was debating if I should substitute some of the grain for Beet Pulp.

This is my fist older horse so just looking for suggestions on what others have done with older horses.
Thanks

Considering that 25lbs of hay +/- 1-10lbs of grain or other supplements is pretty average for a full sized horse who is able to chew properly, that doesn't seem excessive at all for an underweight older horse who cannot get as much out of his feed anyway.

Thanks,
Got a bit worried when I seen how much grain she was getting, I used to having her turned out on pasture with no grain. Do you think I should exchange some of the grain for beet pulp. Reason I'am asking is the vet said grain can make ulcers come back or get worse. She was treated for ulcers in the spring.

Hi Foxy,

As for basic amount, I agree with Sharpie. While I didn't look up those feeds to see their specifics, what concerned me is you say they're grain, your horse has Cushings, you only feed twice daily and it sounds like she's also had ulcer problems. Sounds like the vet is aware of at least some of the probs with grain, but did he elaborate?? I would suggest learning more about feeding & nutrition. Equine Cushing's and Insulin Resistance Information is one good site for info specific to cushings & IR horses.

With all the above considerations, I wouldn't be feeding her ANY grain or otherwise high sugar/starch feed, unless on nutritionist's advice, and would also ensure I could feed it over at least a couple more small meals daily if I was going to. So yes, if she needs more than the chaff/hay stretcher(which should be at least about 2% bwt daily), beet pulp, rice bran, soy hulls, etc would be a better option.

Also you say they get fed twice daily & have eaten their ration after about 4-5 hours. It is not good for horses to go hungry for any length of time & this is also a potential ulcer/colic risk. So I'd be feeding their ration in a 'slow feeder' if you can't feed out more/more often, so they don't go hungry for long periods, particularly over night.

Agree, also make sure you are feeding beet pulp WITHOUT molasses. I'd increase the beet pulp, decrease the "grain" and go for a grain aimed at horses with cushing/incline resistants like Podium by masterfeeds
