How old is this horse? ibsammy, post: ...is just not gaining weight like I would like her to....(from a pasture was) moved to a paddock at the trainers and switched to a grain/hay diet, which I suspect is when she got hind gut acidosis (sp?)/hind gut ulcers. Lots of horses eat hay and grain and don't get hind gut acidosis. Why would such a diet cause hind gut ulcers? Shortly after, she was hauled to Iowa.....but she lost weight pretty quickly. I started feeding senior grain (triple crown) around then......I stopped graining her and she looked "okay". Still thin, but not noticeably underweight as she was before. What kind of time frame did this all happen in? It looks like two moves, first from a pasture to a paddock, then the next place, in Iowa. I started her back on the triple crown and will watch and see where she ends up. How much does she weigh, and how many pounds of Triple Crown does she get? Which Triple Crown feed does she get? How many hours a day is she on the round bale? How much pasture is there? She keeps her head in the hay bale and munches on an alfalfa/grass mix, lives in a pasture with several shelters, has her "friends". I've removed all of the stressors she had but she just doesn't look as good as everyone else on her same diet. Did you put a weight tape on her at any point, or just go on your impression that she was losing weight? Do you know how much weight she lost? I have a truck, but no trailer, so any vet call has to be a farm call. The vet will be out within the next month to get her teeth done, but she just had them done in February and she doesn't appear to be dropping feed/her manure looks pretty good. If her teeth were just done, there's not much to be gained by having the same guy do them again. I don't see any indication that this is her teeth, though. This brings me to hind gut ulcers, I started googling and found these symptoms weight loss and/or general decline in body condition - yes resistance under saddle - she's only been rode about 10 times and isn't resistant, more green bean. I've had her sitting until her weight gets back to where I want it, so it's been ~6 months since she was rode irritability and other changes in attitude - not at all. She's the sweetest mare, I'm not sure I've even seen her pin her ears lack of energy and stamina - yes, though she's always been like this, even when she was fat. She canters around the pasture but doesn't go particularly fast. She has a lot of flourish, but not a lot of speed. Pokey walker, etc. Hard to tell if this is because she isn't feeling well, or just doesn't have motivation to go anywhere fast. loss of appetite - she loves food. She spends most of her day eating hay, and licks her bowl clean when I grain her. behavior indicating discomfort, such as pawing or laying down excessively - she has always pawed, but I attributed it to her playful-gets-into-everything attitude. If you leave anything unattended around her she picks it up and flings it, she'll paw bowls around, etc. She does lay down, but currently has a hoof abscess thats healing so I figured it was related to this. This is making me think discomfort. low-grade anemia She doesn't have the pattern of signs one associates with hind gut ulcers because....welll....The list above is from a supplement maker that when they did their research, referred to all abnormalities in the hind gut as 'ulcers.' I suggest you read this: https://horsenetwork.com/2016/04/truth-hind-gut-ulcers/ In fact, it says... "if you read medicine, surgery and pathology textbooks or other published literature there is no mention of this widespread “hindgut ulcer disease”. It isn’t even mentioned in the horse health articles for owners on AAEP.org." You can read about hind gut acidosis. This may occur when the animal has an 'overdose' of grain. Equisure, which is a form of sodium bicarbinate, appears to lessen hind gut acidity. Okay. Someone mentioned that when horses have liquid coming out with their manure, they have a food allergy/intolerance problem. Well, maybe that is possible, but what that sounds like is 'colitis' - irritation of the colon. It's the colon's job to absorb that liquid around the manure. What causes the colon to not work right? Ulcers? Some people don't think so. There is a handful of different inflammatory diseases that can affect the colon(there are 4). Sometimes these 4 diseases are linked to use of NSAIDS. Then there are other possible causes: infectious diseases, poisons and other things can damage the colon. Depending on the age of the horse, there are other possibilities for weight loss. Teeth? Yes. Many vets do teeth, but some of them miss things. But if teeth are the problem, one expects to see some sort of clue, like wads of partly chewn foo falling from the horse's mouth. And there is always the possibility that the horse does not get enough feed, or that the hay she's getting is too coarse for her (more a problem with older horses). A lot depends on her age, weight, the weight of the feed she's getting, and which TC feed it is. I've never dealt with hind gut ulcers, just your standard run of the mill ulcers. I found abler had a product, but am unsure of the dosing. It seems you have to feed it every 6-8 hours. Is there an alternative? I *might* be able to swing this for a couple weeks, but its going to be very hard and my work/studies will suffer. She's pasture boarded so every feeding is about an hour and a half after getting out there and catching her. Is there a once, or even twice daily alternative? How long do you treat for? Is this something keep her on, or treat and then return to normal life now that her main stressors have been removed? I think you need to find out what your horse has.
