Tenn. Walking horse with laminitis


chrisdris@...
 

Hello -- My horse Brandy was diagnosed last week with laminitis and rotation. He is gimping around (we put frog support on him) and has been given some bute which we are tapering off. I've uploaded his case history, and working on pics and such.
Brandy still has a pretty strong digital pulse, but not laying down. I go soak his feet in ice water 2x per day. He is getting low sugar hay and on dry lot.
Any other advice or tips greatly appreciated! (Especially would like to know about good natural anti-inflammatories to replace bute.)

Hi, Chris, and welcome to the group! I am glad you have found us, but sorry that you and Brandy are going through this.

What a great job you have done on your case history. First things first: no beating yourself up for not recognizing signs of laminitis! None of us were born knowing this stuff, and for most of us laminitis is the last thing on our mind for various lameness issues.. We thought Merlin (at age 27 and on) just was stiff from arthritis. Once we got the correct diagnosis, and changed the diet, his stiffness on the front disappeared. *sigh*

I would guess that the smoking gun here may be the recent lack of exercise, plus some grass turn-out.  It is also possible that the hay he was on was high in ESC and /or starch?  Good that your new hay is at 7.7% ESC+starch, but I would also continue to soak until he is over this crisis.

There is a good anti-oxidant pain reliever called PhytoQuench, that people have had success with:  https://uckele.com/phyto-quench-powder.html  Another anti-oxidant/pain reliever is Mov-Ease from My Best Horse:  http://mybesthorse.com/movease.html    Rather than stopping the bute cold-turkey, it is best to take a week or so, and stretch out the doses. So, go from twice daily to once daily for 2 doses, then next dose 36 hours later, then go 48 hours, then stop. (longer weaning off of bute to avoid "NSAID rebound pain" when they have been on the bute a long time, but for Brandy you can fast-track as he hasn't been on it that long).  There is more information in this folder:  https://ecir.groups.io/g/main/files/Pain%20Medication%20and%20Alternatives  , including a file on transitioning from bute to Phytoquench.

Icing the feet will help with pain relief, but won't actually do much for the laminitis, since endocrine laminitis is not primarily an inflammatory condition.

Here is the *very* complete full welcome letter, with some tweaks:

The ECIR provides the best, most up to date information on Cushing's (PPID) and Insulin Resistance (IR). Please explore our website where you'll find tons of great information that will help you quickly understand the main things you need to know to start helping your horse. Also open any of the links (in blue font) below for more information/instructions that will save you time.

 

Orienting information, such as how the different ECIR sections relate to each other, message etiquettewhat goes where and many how-to pages are in the Wiki. There is also an FAQs on our website that will help answer the most common and important questions new members have. 

Below is a general summary of our DDT/E philosophy which is short for Diagnosis, Diet, Trim and Exercise.

 

DIAGNOSIS: You already have a pretty firm diagnosis of IR/EMS.  Although the December 2017 ACTH looked good, I would be a tad suspicious that PPID may now be a player here as well, with his ACTH now above normal. It should be at its lowest in April and May, so the April result of 25 pg/ml might (or might not) be actually normal.  There are two conditions dealt with here: Cushings (PPID) and Insulin Resistance (IR). These are two separate issues that share some overlapping symptoms. An equine may be either PPID or IR, neither or both. While increasing age is the greatest risk factor for developing PPID, IR can appear at any age and may have a genetic component. Blood work is used for diagnosis as well as monitoring the level of control of each.

PPID is diagnosed using the Endogenous ACTH test, while IR is diagnosed by testing non-fasting insulin, glucose and Leptin. Leptin is the hormone that says "stop eating". Knowing this helps to differentiate if a horse is IR "at baseline" or if an elevated ACTH is "driving" the insulin up. (In Europe, substitute adiponectin for the leptin test.)

*Before calling your vet to draw blood for tests, we suggest saving time and wasted money by reading these details and then sharing them with your vet so that everyone is on the same page regarding correct testing and protocols.

*Please remember to request copies of the results of all the tests done rather than just relying on verbal information. Your vet should be able to email these to you. If you have previous test results, please include those as well. All should go in your CH, but if you are having any trouble with the CH, just post in the messages for now. 

Treatment: IR is a metabolic type - not a disease - that is managed with a low sugar+starch diet and exercise (as able). The super-efficient easy keeper type breeds such as minis, ponies, Morgans, Arabs, Rockies are some of the classic examples. PPID is a progressive disease that is treated with the medication pergolide. Some, but not all, individuals may experience a temporary loss of appetite, lethargy and/or depression when first starting the medication. To avoid this "pergolide veil" (scroll down for side effects), we recommend weaning onto the drug slowly and the use of the product APFThe best long term results are seen when the ACTH is maintained in the middle of the normal range at all times, including during the annual seasonal rise. To accomplish this, the amount of medication may need to increase over time. Neither condition is ever "cured", only properly controlled for the remainder of the equine's life. If your partner is both PPID and IR then both medication and diet management will be needed. 

 

DIET: Almost all commercial feeds are not suitable - no matter what it says on the bag. Please see the International Safe Feeds List for the safest suggestions.

No hay is "safe" until proven so by chemical analysis. The diet that works for IR is:

  • low carb (less than 10% sugar+starch)
  • low fat (4% or less) 
  • mineral balanced  

We use grass hay, tested to be under 10% ESC + starch, with minerals added to balance the excesses and deficiencies in the hay, plus salt, and to replace the fragile ingredients that are lost when grass is cured into hay, we add groundflax seed and Vitamin E. This diet is crucial for an IR horse, but also supports the delicate immune system of a PPID horse. 

*Until you can get your hay tested and balanced we recommend that you soak your hay and use the emergency diet (scroll down for it).  The emergency diet is not intended for long term use, but addresses some of the most common major deficiencies. Testing your hay and getting the minerals balanced to its excesses and deficiencies is the best way to feed any equine. If you absolutely cannot test your hay and balance the minerals to it, or would like to use a "stop gap" product until you get your hay balanced, here's a list of "acceptable" ration balancers

There is a lot of helpful information in the start here folder so it is important you read all the documents found there. The emergency diet involves soaking your untested hay for an hour in cold water or 30 minutes in hot water. This removes up to 30% of the sugar content, but no starch. Starch is worse than sugar since it converts 100% to glucose while sugar only converts 50%, so starch causes a bigger insulin spikeMake sure you dump the soaking water where the equine(s) can't get to it. 

What you don't feed on the IR diet is every bit as, if not more important than, what you do feed! No grass. No grain. No sugary treats, including apples and carrots. No brown/red salt blocks which contain iron (and sometimes molasses) which interferes with mineral balancing, so white salt blocks only. 

No products containing molasses. No bagged feeds with a combined sugar and starch of over 10% or starch over about 4%, or fat over about 4%. Unfortunately, even bagged feeds that say they are designed for IR and/or PPID equines are usually too high in sugar, starch and/or fat. It’s really important to know the actual analysis and not be fooled by a name that says it is suitable for IR/PPID individuals.

We do not recommend feeding alfalfa hay to IR/PPID equines as it makes many of them laminitic. Although it tends to be low in sugar, many times the starch is higher and does not soak out. Additionally, protein and calcium are quite high, which can contribute to sore footedness and make mineral balancing very difficult.

 

TRIM: A proper trim is toes backed and heels lowered so that the hoof capsule closely hugs and supports the internal structures of the foot. Though important for all equines, it's essential for IR and/or PPID equines to have aproper trim in place since they are at increased risk for laminitis. After any potential triggers are removed from the diet, and in PPID individuals, the ACTH is under control, the realigning trim is often the missing link in getting a laminitic equine comfortable.

Sometimes subclinical laminitis can be misdiagnosed as arthritis, navicular, or a host of other problems as the animal attempts to compensate for sore feet. 

You are encouraged to make an album and post hoof pictures and any radiographs you might have so we can to look to see if you have an optimal trim in place. Read this section of the wiki for how to get a hoof evaluation, what photos are needed, and how to get the best hoof shots and radiographs.

 

EXERCISEThe best IR buster there is, but only if the equine is comfortable and non-laminitic. An individual that has had laminitis needs 6-9 months of correct realigning trims before any serious exercise can begin. Once the equine is moving around comfortably at liberty, hand walking can begin in long straight lines with no tight turns. Do not force a laminitic individual to move, or allow its other companions to do so. It will begin to move once the pain begins to subside. Resting its fragile feet is needed for healing to take place so if the animal wants to lay down, do not encourage it to get up. Place feed and water where it can be reached easily without having to move any more than necessary. Be extremely careful about movement while using NSAIDs (bute, banamine, previcox, etc.) as it masks pain and encourages more movement than these fragile feet are actually able to withstand. Additionally, NSAIDs (and icing) do not work on metabolic laminitis and long term NSAID use interferes with healing. Therefore, we recommend tapering off NSAIDs after the first week or so of use. If after a week's time your equine's comfort level has not increased, then the cause of the laminitis has not been removed and keeping up the NSAIDs isn't the answer - you need to address the underlying cause.

 

There is lots more information in our files and archived messages and also on our website. It is a lot of information, so take some time to go over it and feel free to ask any questions. If you are feeling overwhelmed, don't worry, you will catch on, and we are always here to help you! 

 Again, welcome!
