Hindgut Acidosis - Sorry, long story!

I got my PRE Stallion 2 years ago on LWVB and quickly saw that he windsucked and was girthy. I assumed ulcers and started the long and expensive journey of trying to find a solution (knowing that it could be caused by other pain/stress). He is the most gentle and genuine horse I have ever met and I needed to do my best for him.

In the end the best treatment was moving from haylage to hay, ERS Pellets and Equishure. This got rid of his noisy, gassy belly and he windsucked less.

Forward to this year and the horses were slowly introduced back to the paddock after winter and after a few weeks I noticed his shoulder twitching like he had a fly on it. I just assumed a trapped nerve and massaged him - he still seemed ok when ridden. A week later I rode him and he was fine for an hour and a half hack and then the last 10 minutes home he started twitching on his sides and was walking swaying left and right. After 10 minutes at home he seemed ok again. I gave him some electrolytes. But then next day the twitching was more by his shoulders and flanks, his joints were clicking and he was withdrawn and not eating and I noticed he had lost weight and muscle. (he is a poor doer but I thought the grass would help put weight on!). The vet came out and said his heart rate was double and he had a fever. Bloods were taken and showed inflammation. He had 2 courses of anti-biotics and bute. He started eating and stopped twitching as much.

I googled his symptoms and thought the worst but then started putting 2 and 2 together. He probably has Hindgut Acidosis. My husband has been out of work for a while and I couldn't afford the Equishure and he hadn't been on it for about 6 weeks and then he was put out onto the spring grass (albeit slowly). I'm guessing the sugars in the grass dropped the PH levels and caused the inflammation and build up of lactic acid in his muscles and joints.

I have changed his diet so he is on Rowen and Barbary Solution mash (2 scoops a day) and scoop of Honeychop Lite and Healthy, 1 measure of Equishure and pre/probiotics 3 times a day. He still goes out on the very short grass paddock 2-3 hours a day and has hay in a haynet the rest of the time. He is back to himself and feeling good, apart from the weight - he is still very ribby and no muscle on his bum. It has been about 4 weeks, am I expecting too much too soon? Any other ideas?
 
Just really wanted to hear of other people's experience of Hindgut Acidosis or putting weight on a horse that is/has been poorly. Forgot to say that he is 21 years old. x
 
Have you done a worm count and had his teeth etc checked? Might be worth a cushings test as well. They are free at the moment.

My cob came very lean and with definite stomach issues. They've cleared up completely feeding pink mash and hes gained weight to the point hes probably going to need muzzling soon to stop him being fat. I only started the pink mash as its low sugar/starch and I wanted something to feed him while I got everything else sorted before sending him to be scoped. Hes never gone to be scoped as hes fine now, well better than fine. He looks in rude health! :)

the only other thing I did as well as ad lib hay was to feed him a trug full of agrobs chaff with a little bit of pink mash to dampen it down, ever afternoon. He would eat more of that than he would of hay and it helped him gain conditio

Thank-you. I wanted to feed Pink Mash but have had problems getting hold of it and the company never got back to me when I asked about suppliers! He has his teeth done every 6 months and recently wormed with Pramox. I haven't done a Cushings test but may do now it's free.

How long did it take for him to start putting weight on?
 
I bought him in January, he stayed pretty lean for the first 6 weeks, but it took me that long to sort his mites and get his back done etc, from there on in he gained weight steadily. Hes been maintaining nicely for a while now, but hes out on good grazing and I just noticed today hes tipping the balance from good weight to looking a bit chubby.

You can buy it online or if you look here you can see where your nearest stockist is:

Thanks. I looked on there and contacted a few places but no=one actually stocked the Pink Mash! I ordered it online with a company and then they never processed my order or replied to my emails enquiring about it! I then emailed Keyflow and someone replied saying they passed it on to someone then no reply. So I have given up and gone with the Solution Mash that at least I know I can get hold of.

The problem with my horse is that the sugars in the spring grass set off this whole acidosis episode and all the muscle twitching and inflammation. He is out on the paddock now that doesn't have much grass on it but if he gets more grass then he starts twitching and joints clicking again. I suppose when the other horses have eaten it down a bit he can go in the other paddock with a bit more grass. I have just been hacking him out for an hour max in walk twice a week and luckily the saddle cloth hides the ribbiness or I'm sure I would have people calling the RSCPA :(.
 
Have you considered PSSM? Twitching and soreness are two of the common symptoms.

I did ask the vet about it right at the beginning but he dismissed it saying he only saw it in draught breeds and not Andalusians. But I have put him on a high oil diet and restricted grazing which should help?
 
I read somewhere of someone who's horse was suffering from hindgut acidosis - the treatment was expensive so she had made her own mix, I think it was Bicarbonate of Soda mixed with corn oil - the corn oil prevents it from being broken down to early so that the Bi Carb reaches the hind gut. However I cannot remember the quantity she used. May have been a dessert spoon of Bicarb, then mixed with oil until its all coated before feeding.

There was no twitching with mine and the only soreness he had was directly related to mites and the back issue that I had treated and quickly resolved. I think there is probably something else going on with yours OP

It's funny you should put that as I just started this week on mixing Sodium Bicarbonate with oil in his 3 feeds (about a tablespoon) as well as the Equishure for now. He usually eats anything but doesn't like the taste of it but it is slowing his eating down which is a plus. I think he is feeling better as he is being very vocal and frisky!

I haven't seen any twitching of his shoulder or flanks for a while so hoping we have sorted that out. It is all such a worry as I seem to be overanalysing everything he does and then worrying.
 
I have a horse just like this, albeit a big TB. Diagnosed with inflammatory bowel disease nearly 3 years ago, this was caused by acidosis. The only thing that works for him is Equishure however I have to feed 60g a day (2 scoops) and possibly more during grass flushes. Yup its expensive but it has literally saved his life as nothing else worked. I limit his grass during spring, supplement with soaked hay and feed Keyflow Pink Mash, Keyplus (which is a high calorie rice bran supplement) and the balancer with a plain chaff. He cannot tolerate sugar beet of any type, alfalfa or Copra, these immediately make him show symptoms again.

Recently he seemed to be having colic type episodes which was confusing as his gut has been great and he looks and feels fantastic. Vet suspects that he is actually tying up and has PSSM or similar. Tested for PSSM and was clear so going to the biopsy for RER. My vet suggested that in the mean time we start him on vit e, b vits, salt and from reading up on RER I started him on magnesium. He is doing fantastically well and is piling on muscle and doing really well under saddle. He is back out overnight in a field with very little grass and his gut is great, he goes out 24/7 again this weekend.

I tried the homemade bicarb and oil and it didn't work for him but I have heard of other folk believing it has.

He also did 3 month on ranitidine to aid the healing in the hind gut as acidosis can cause hind gut ulcers.

I find mine needs something like Rice Bran and a good quality, high amino acid balancer to keep weight and bulk on. As soon as the grass starts to affect him he drops weight and muscle, he's the only horse I know who gets thin on spring grass!

Thank-you so much, this sounds like my boy. I took him off alfalfa and beet. The mash he now has is Soya hulls and Soya oil - which I'm hoping will work for him and not another one to avoid!. He has Vit E added too.

Do you think it is the magnesium that helped yours? Which amino acid balancer do you use?
 
Hi, I had tried lots and lots of different foods/medicines/supplements but not those two. I enquired about the alpengrun mash but as my hubby is out of work I just could not afford any extra. In the end he was having enough food to feed 3 horses but still not putting on weight and still shaky when walking. I then noticed his melanomas around his anus were growing again and more were appearing under his ears/jaw.

I could not stand seeing him in pain (although as a stoic horse he tried his best at hiding it but the eyes don't lie) and made the decision for him to go to sleep a couple of weeks ago. A very sad loss for a great horse but he deserved not to suffer xx
