Interesting. I was super freaking lucky and have been fortunate enough to try the pellets thanks to @IPEsq but I also moved my mare up from ultium to strategy which makes me nervous because I’d usually never dream of feeding anything with that high of NSC. I haven’t been supplementing with vitamin e yet just because my girl is on pasture and I know she gets it from the grass.

I think this is a newer development. My vet reached out to dr. Valberg and the newer guidelines she emailed us was the first time I had heard about the higher NSC and it looks like it’s from January 2021 but she sent it to us mid June, so I’m assuming it’s still current. I think omolene 400, strategy, and then nutrena 12% were the ones they recommended for horses that struggled with low energy/ low impulsion. I can email you the new guideline if you want to pm me!

A lot of people with PPSM Type 2 horses find they do best on a lot more Vitamin E than is ā€œtypicallyā€ recommended, FWIW.

Can you send me the guidelines they sent you? Curious if it’s the same thing I received.

Sure! It sounds like you’re doing exactly what they say though but if you PM me your email Im happy to send it over!

Yea I will most likely start with the vitamin e at some point before she goes back on hay but I also just want to change one thing at a time so I can see what’s helping and what’s not.

That makes sense!

Ah, I see. I guess I was curious since the recommendation for PSSM type horse is usually to limit NSC. And some of the affected breeds are not typically harder keepers.

I’d like to see that too. My vets here came to recheck my horse since he’d given himself a nice little muscle tear but also were wanting to see where he was in comparison to last fall. They thought he still tended to act muscle sore easily. I told them about the failed MFM Pellet experiment etc. We talked then more about the exercise portion of the protocol and how I felt that was going versus the exercise needed to rehab his SI. So far, to me, fewer rest days is better, but some of the days can be more on the lines of ā€œactive recoveryā€ versus total rest or hard work, like a 45 min on the buckle walking hack.

Anyway, I digress. Their last visit they said as he gets older, I really ought to watch his sugars given his more voluptuous tendencies :grin:. He could never get a full serving of any feed that’s not an RB for any length of time without being obese, but I do feed him some TC Complete (2.5lbs max per day plus 1lb RB per day) for it’s digestibility and to make the rest of his food more interesting.

He does have low energy issues. Saline nebulizer is helping so far this summer as compared to last summer. But I have struggled with feeling like I’m feeding him for performance without turning him into a blimp.

Would love to see the new guidelines!

That is still the recommendation for PSSM Type 1 (to limit NSC) but not for Type 2.

Do you think he is Type 1? If he’s a WB (and IIRC he is) the odds are SO MUCH BETTER he’s Type 2. You could easily answer the Type 1 question with a genetic test, it’s just mane hair so not invasive and only costs $40. Then for sure you would know if he was Type 1 or not. If he’s not Type 1, the low NSC recommendation doesn’t really apply to him. Type 1 and Type 2 are totally different, really it’s a misnomer to call them both PSSM. Type 1 is PSSM and Type 2 is everything with similar symptoms/characteristics that isn’t Type 1 and we don’t quite know how to sub-divide yet.

I think the low NSC recommendation used to be the recommendation for type 1 and type 2 until pretty recently though. When I first started looking into PSSM I watched a webinar from dr. Valberg in 2017 and they were recommending low NSC and high fat for PSSM2 and now they’re pretty much almost saying the opposite 4 years later.

In my head I thought that she had only had her horse for a shorter period of time not for many years but I also could be forgetting the details. At any rate the recommendation now for type two is not to have the same diet has type one. Now they have completely different recommendations for the two different types in terms of feeding regimen

Can you post the recommendation or pm please.

He’s most likely not Type 1. I have had him a short time. Last horse we suspected was MFM but he passed before there were recommendations on that. He didn’t do well on soy either. Current horse I’ve had about a year and a half. He’s had various things going on that could explain exercise intolerance that’s not PSSM or a variant but it’s been on the radar. He also has much more of an IR/east keeper body type than my previous horse. But at the same time, he is very much the body type of his sire who has had a lot of high level performance offspring. And when I’ve had a Rolfer work on him, some of the typical fat pad areas don’t actually feel like fat and lose their tone after fasciae work. So it’s like his muscles get sore and are a bit hyper toned even when he’s kind of out of shape. That said it isn’t hard to let him get too fat. This horse has good work ethic but tends to feel like he lacks energy and can sometimes have a hit the wall kind of feeling easily in a ride that isn’t that long or difficult. Just poops out.

I did a lot of research and listened to a webinar from Dr Valberg some years ago when we were trying to figure out my other horse. At that time, she had named MFM but that was about it. And the diet between PSSM 1 and 2 was not that different in terms of NSC (more varied with fat and protein suggestions).

I think the change in protocol for feeding Type 2 is really new… like maybe a 6 months old, max.

It’s a version of this information slightly condensed and reduced to a PDF. I am not sure how to post a PDF on this board but I’ll try…

2021 Jan MFM recommendations.pdf (147.7 KB)

This is from 2020, so older, but I found particurly helpful in terms of general background and understanding the different conditions that all get lumped into the term ā€œPSSMā€

Also good info here about MFM in warmbloods, although obviously this is a source trying to sell you something…
