| For the past year I have been struggling with my coming 6 year old mare in twitching, behavioral issues, pain-like symptoms, ect and I had every test under the sun done including ultra sounds, lamness exams, chiro, ulcer meds, vision problems, ect and the vets in my area (not really a lot of equine vets around here) all (including friends) told me she was fine, there was nothing wrong, I just need to get after her, I'm seeing things, pretty much the works and I stumbled across an article with a mare owner describing the same symptoms.
I didn't want to get my hopes up after being let down a lot but I went ahead and tested for PSSM Type 1 and 2 (I actually got to be part of a study for a blood test for type 2 instead of a muscle bioposy!) and she came back positive for PSSM 2! She is N/P2 and we believe it came from the sires side (sorry can't release his name until they finish testing) but we're 99% positive its from him. Type 2 isnt as well known, and the forum on FB has been extremely helpful but type 2 is treated a little differently than type 1 and I was wondering if any barrel racers could share their experiances and feeding plans with me? I ordered Natural Vitamin E, Salt, Wheat Germ Oil (now not really a recommendation), and I'll be asking the feed store what they carry for Magnesium. I'm also going to start her on Purnia WellSolve L/S (now feeding Purina SuperSport and/or Triple Crown 30 as they are both good options) she is an easy keeper, very well muscled, high strung, and anxious (probaly because everything used to hurt her!) So I would love advice, success stories, ect  I have a basis of where to start but I know I'm probably missing stuff!
She had to miss her futurity year and now we are back with adding 5 min of excercise a day but I am VERY new to this. I do know that every type 2 horse that has tested positive has been linked back to two OLD horses "Midnight" and "Peter McCue" except 2 and there are a LOT of horses that go back to them and are suspected carriers including Dr. Nick Bar who my other mare is currently in foal to a son of his so the baby will be tested right away, Easy Jet and Jet Deck, Top Moon, Sonny Dee Bar, ect. I know there are plenty of horses that are competitive including "Martha" but I want to get my mare comfortable first. My belief is that there are a LOT of horses out there that are suffering from type 2 whether they are mildly affected or severe like my mare but no one knows about it/wants to muscle bioposy. The gentleman doing this study just released the blood test to the public Edited: the hair test is now public :) Equi-Seq is the website Hopefully in the coming years it will also be added to AQHA's 5 Panel and I think a lot of people will be surprised at who is found positive. I know we are now going to be testing almost all of our horses now. :)
Editied to add since this was bumped up:)
Spelling and changed the feed reccomendations since it is now high protein...still haven't rode her but she's on the right track!

Location: Peg-Leg Julia Grimm | Are you on facebook? there's a great page over there called PSSM Forum. They are supportive and have tons of experience with horses that have PSSM. They can help you with diet and exercise ideas to help you make your horse the best possible version of herself. Good luck. |

Location: Feeding mosquitos, FL | I'm running a mare now that we think is PSSM Type 2 - she had all the clinical signs, was negative to the Type 1 test, but we just haven't done the biopsy. She had muscle spasms, anxiety, high-strung, INTENSE about everything in her life.
As long as we manage her diet, she's completely fine and running hard. Her diet currently is Seminole DynaSport (which is 9% starch), MagRestore (magnesium supplement), a little alfalfa, and all the grass hay she can stuff in her face. She was on WellSolve L/S and Amplify but I couldn't get it as easily as the Seminole.
I'm curious to know the bloodline of your mare - there are a few horses locally that go back to one particular line that are all symptomatic.
Edit: I forgot to add - for exercise, she doesn't get ridden every day but she is turned out 24/7.
Good luck! With good food and a sharp eye, she'll be back to running in no time!

| I am apart of the FB page and they are very helpful, just want opinions from barrel racers :) As soon as I can release the name I will post it! She's by a stud who was pretty well known but was sold and kind of went "off the grid" and isnt currently standing to the public but they had plans to stand him for 2017. He wasnt 5 paneled because it wasn't required at the time but they are testing him for both types now. I will say he is by a very well known stud and out of good bloodlines that pretty much everyone has, kind of scary! Never heard of Seminole but I will check that out!! |

| Sent you a private message ;) I do know there are a lot of horses out there with bloodlines that are either carriers or have offspring that are carriers and there is a website, BRIDGE EQUINE with a whole database that you can look up specific horses and see who is suspects. Easy Jet and similarly bred horses that go back to the two mentioned horses I believe are also carriers. |

| I will also say, we do know that the mare also goes back to 1 of the horses but shes 21 and own/know all of the foals and none are symptomatic and the two horses that we have had by the stud (as well as a few others in the area that we know) are symptomatic/show signs so it's a pretty good sign that he's the one. Plus the fact that he's not tested. |

| Bibliafarm - 2016-04-20 9:13 PM Wellsolve is great feed
Hopefully my feed store carries it, I've heard great reviews! I'm still new to the actual feeding process of this and I know they are in the works of actually changing the name of PSSM Type 2 but I love hearing sucess stories |

Location: southeast Texas | I too am in the same study as you. Am waiting my results.
My horse is by a stallion that was well known for throwing Broncs. Found this out after talking to some old timers in the area the stallion is from.
I tried all the feeds recommended for PSSM. Saw marked improvement in attitude each time. But he was still off. Vets all thought I was nut during lameness exams. Horse had nice spring to his steps after flexion. No obvious lameness.
But under saddle I could feel "it". If you didn't ride every day, you had better lunge him before getting on. He would have days where he would work good. The next, who knows. He would just be "off"
Now he is on an all hay forage diet. Alfalfa / jigs hay plus his supliments. Added fats in the form of renew gold and two squirts of soybean oil. He has never looked better. All thru the years you could get weight in him. Now he has bulked up, darkened coat color.
He is a lot more consistent in his barrel runs. You don't ride him every day, no big deal. Same horse you stepped off of when you get back on.
His personality has blossomed. He wants to visit people and other horses.
Im glad others have paved the way for us to follow in helping these athletes |

| So have they definitively determined that PSSM 2 is genetic? Has a gene been identified?

| Sorry guys just getting to the computer (my mare foaled!!) yes they have determined the gene and it is a dominant genetic disorder. Everyone knows that Hancocks are the broncy ones and lo and behold, they all go back to Midnight and Peter McCue and I'd be willing to bet a lot of money the two we had were both PSSM 2 positive because they showed all the signs (we just didnt know it). I hope you have good luck in the study roxieannie and hopefully pleasntly surprised! Im exhausted but when I get back on tomorrow I'll post more information, part of the reason they want to rename the type 2 is because it's a different form of glycogen storing and they're fed a little differently, Im still learning though! |

| My daughter's horse ties up. I am still learning about the problem. I am interested in having her tested to see what is going on. She is on a special diet after colic surgery so that doesn't help her situation either. She is on Purina Senior feed, but I've been told that it has a higher starch content. I am struggling with the research trying to decide what to feed. |

| I am part of the study for type 2 as well and am waiting for my results. My gelding tested negative for type 1 via hair sample. He does tie up, has tight musles, twitches, tail swishing etc. I've pulled blood and he had a slightly elevated AST level. He's a pretty classic case. As you know, they're saying that they believe PSSM2 is not as sensitive to carbs BUT, I know for a fact mine's effected by carbs as he will tie up if I feed him even 1# of oats a day. So, if he's not PSSM2 he's RER or something. We obviously just have to learn what works best for each horse. Mine is on a low-starch/high protein diet that's mainly alfalfa based (I balance with some phosphorous). He does get some fat too and I've always fed him vit e an selenium (always natural vitamin e) as well as a few other things. As far as this issue is concerned, he's totally maintained by diet. Won't tie up even if I skip a couple of days of riding, muscles aren't tight, nothing. Which leads me to believe even more it's PSSM2 vs RER because if it was RER he probably wouldn't do as well with having an alfalfa based diet. But, he's got an unrelated soundness issue that I'm still dealing with. Hopefully that will be behind us in the next few months as well. |
