TLDR; I’ve read countless threads but nothing that speaks to my unique situation.
Overview: 16.1 hh 7 y/o OTTB mare 3 years off the track. I’ve had her a year. She came to be severely malnourished and sickly. A year later she’s at the best weight she’s ever been at 1200, flat, muscular topline, bulging muscles, the whole bit. I was so happy. It took INTENSE dedication. This was 2016
Since then, 2017, we have had an incredibly difficult year building muscle and weight. In winter of last year we lost almost all of our weight and dropped to 980. No feed changes but I was ignorant and did not blanket (she was clipped). We slowly built it back up to 1150 in May.
Things were wonderful until winter hit again. She’s a BCS of 5. Can’t see ribs, can feel if you press. Her topline has suffered yet again. Her back looks more “^” than “n” , if you get my drift…
She has calcification on her lumbar area so 4 spinal processes are raised. More fat and muscling helps hide them.
She is my dressage mare. She is ridden by my trainer 2x a week with 1 lesson a week. I ride her on the weekends in the winter. She is in what I would consider medium-heavy work (an hour of very intense, correct and round riding a day).
We just moved to our new facility a week ago. She’s been treated for ulcers several times. She is not insured so medicine is expensive but my vet and I use ranitidine for her, usually 2 months at a time (t’s not as fast to work as gastrogard). She’s also has been on SmartGI, tri-amino, and smartomega 3. Right now she is on SmartGI, SmartOmega 3, and SmartMuscle (new smartpaks to come).
What I have noticed: I’ve put her on and off tri-amino. right now she is off tri amino, and she’s dropping muscle. When she’s been on tri-amino her topline has been great. I know feed-through supplements do not always work. Is this a coincidence or is tri amino helping?
She has a VERY muscular neck. it is the most well-formed part of her body. It is very thick and very, very toned.
I’ll say right now in my neck of the west coast hay is very expensive. The place I am at now is 2x what I was paying before. I was able to afford 2 extra bales a week at old place. New place doesn’t allow that in the budget but it is full care. She gets 3 meals a ay: 1 flake alfalfa in AM, 1 flake timothy in afternoon turnout, 2 flakes timothy PM dinner. Total is 20 lbs of hay (weighed).
She is between 1085-1180 right now weight wise. Muscle is building everywhere but the topline. When she is tense, cold, or in pain, because her lumbar is fused (so is the thought) she does not hollow her back like a normal horse would but tightens and tenses the muscles around her spine and they drop away. Her spine stays parallel. she is EXTREMELY EXTREMELY PRONE to a sore back and adequate muscling has helped prevent discomfort.
She is always ridden through, with contact, stepping under herself and a round frame. It is the only way we have found to maintain her muscling.
right now she is fed 2 lbs fortified rice bran, and 4 lbs nutrena safechoice perform grain (2 meals, so halve each of those servings).
Is there anything I am missing? I am so concerned. She is blanketed at night, clipped.
I have access to these feeds:
Fortified rice bran
Fortified wheat bran
Nutrena Safechoice Perform, Original, and Senior
Nutrena XTN
LMF (i think most of them)
Alfalfa and Timothy Pellets
Alfalfa Cubes
I do NOT have access to Triple Crown products. I also do not have the ability (car) or the budget to add supplemental hay. I can ask barn if they will feed more but we do not have free choice hay out here, this is as close as I can find.
Saddle fit is 100% custom to the horse (I hate it but it fit her) and flocked and has been fitted less an 6 months ago.
Thanks to everyone who can help.
EDITED to add that she has seen a bodyworker twice in the past 3 months and they have said that yes she has a topline and that her back will always be more roof-like. but I am concerned about her lumbar area that always seems to stick up.
MORE EDIT: When she is due for a trim she tends to tense her back.Every time we do her feet magically she’s “gained” back the 50 lbs i swore she lost. She’s due for her next trim next weekend, she is on a 7 week cycle but I usually call in my farrier at 6 weeks. This will have been 5 weeks - she grows very fast.
