I started really noticing about 2 weeks ago that my mare wasn’t finishing her feed. She’s never been a lick the bucket for 10 minutes when done kinda girl but she normally finishes everything. 

I have a text in to my vet but while waiting, do y’all have ideas?

I board my horses and they are on grass 24/7, I o oh get out to feed once a day, she gets

1 scoop Bluebonnet Omega Force

200g Putin’s Outlast

1 scoop (from in the containers) of Race Today, Anihist HA, and Equisteo Flexadin. 

She has been regularly wormed but when I went 3 weeks ago for shots and coggins vet said she needed to be tube wormed. While I was there I had a succeed test done to check for ulcers and it was negative.

Any and all suggestions will be considered, I want my girl eating again!

edited to add: if I give her with alfalfa she does eat it

Thats kinda alot of supplements you are adding to her feed, I would cut out all the supplements for a while and see if she will start eating her feed again, or call Jyme Nichols at BlueBonnet, shes the Dicector of Nutrition there and ask her what she thinks, heres a number for BlueBonnet 800 365 2456, she is so easy to talk to and super nice.

This time of year my boys will gorge themselves on the nice green grass we have so I cut them back on their alfalfa. It usually takes a week or 2 before they will go back to finishing their feed. So if your pasture is nice and green they might just be full. 

Same thing with all of mine, this time of the year I cut their feed in half. I dont feed them the same amount as I do during winter months.. 

I took all supplements out one night and didn’t make a difference. 

Race Today is for bleeding, Anihist is for allergies or she itches out her mane and tail, Flexadin is for joint health, Outlast is for ulcer prevention. 

Vet texted back and wants her on omeprazole to get that ruled out even though they succeed test was negative.

This... especially if they are turned out 24/7 on pasture.. I had my hubby shred our pastures today because it was just nuts out there! And my boys only get 4-5 hours of turnout time right now.. and I have to chase them down to get them to even come up to eat! They arent even finishing their hay nets at night right now. Too full and dreaming of fresh lush pastures I reckon! 

My thoughts exactly.

My husband has one horse (his are in a dry lot) that quit finishing his grain a week or so ago, and we have ended up stripping down what he gets from small amounts of 3 types of grains to a larger amount of one grain. We think there were some nutritional overlaps in the multiple types of grain he was getting so the horse was just not finishing his feed. He's still not gorging himself on grain but he's getting closer to finishing what we give him so I think it's working.

This is where I always start when a horse isn't finishing grain. I grab a couple tubes of UlcerGard from TSC. Give 1/2 tube per day for 4 days. If I notice that it's making a difference I start them on a 30 day ulcer treatment, if no change then at least I've ruled that out.

I was going to say that is a common symptom of ulcers when they go off their grain/feed but will still eat grass & especially alfalfa hay.

My mare isn't eating great right now either. My sister has a few horses who aren't eating too well in the last day or so either. My mare isn't turned out right now so hers isn't gorging on grass, but my sister's could be. I started my mare on Zesterra and trying it for a bit. She's picked back up and is eating her grain but not really all her hay. Wish I had answers, but I'm asking the same thing as you. 

What do y'all do for long term ulcer prevention? I had my mare on Omeprazole for a long time but didn't want to hurt her gut health so I took her off and did a mix of Zesterra on race days and then Outlast daily. Vet thinks even though Succeed came back negative that she has ulcers. 

Once I finish ulcer treatment...what do y'all use? I don't want to keep her on Omeprazole only due to the "long term effects" that I'm already worried 4+ years of being on it will have done. 

Check the feed date manufactured- I feed Omega Force as well and my gelding all of the sudden started not finishing, or eating very slow. Checked the date on the feed sack and it was >6 months old, and had a stale smell to it. BB replaced without any issues and my gelding went back to normal appetite on fresh feed. 

Hmm..I'll look at it tonight. I get it from a local person who orders regularly so I wouldn't think it would be old...never know.

Hey, may be related just FYI.... but my two horses QUIT eating the outlast about 45 days into feeding it. At the beginning they ate it right up, then just quit. May or may not be related. I like the concept but not sure I would use it daily. Maybe just race days or when hauling. I really like the Curost stomach formula but its quite expensive... I use the Depaolo EXCEL and it doesn't have as much of the ingredients as curost, it still seems to work really really well on my horses. THey get 1 scoop 2x daily and 2 scoops 2x daily when I travel or race days. Hope that helps! 

LOL My feedstore hates me sometimes because I am OBSESSIVE about feed freshness. Before I even buy it I go in the back and check dates. Luckily Triple crown and Renew gold make it easy to check dates. I have no problem pulling a bottom bag with a newer date than the ones on top. LOL I will not feed a feed more than 60 days old... 90 days is absolute max/emergency situation. Unless its renew gold , they are good for a year but still keep it to under 90 days if at all possible.
