Has anyone else had performance problems in their Dales ponies, combined with high muscle enzymes? Would really love to hear from anyone who has, as I try to figure out whats going on with my gang.
Over the last few months, Ive been looking into the cause of one of my Dales ponys reluctance in his work (reluctant to trot, slow, stiff hind limb action, grinding to a halt, inconsistent carriage) and have had several blood tests done along the way, as well as a biopsy to check for signs of muscle disease such as EPSM/PSSM/RER etc.
Ive also had all the ponies tested by hair sample for type 1 EPSM, and all came back negative for that. Only £25 per pony, so quick, easy and painfree to ponies and my wallet! So at least that ruled out one type of EPSM.
Anyway, last week I decided to have all my ponies (5 purebred Dales ponies and one partbred Dales) blood tested at least as a baseline for future reference, but also because Ive had a nagging feeling about a few of them being not quite as consistent in their work as they might be.
The blood results have ALL come back with abnormal muscle enzyme levels (CK, AST and LDH), and I could have predicted those which would come back highest and lowest (because they tie in with the scale of reluctance to work): Max (the pony whose had most investigations) has CK levels 10X the top normal of 350; the rest of the gang range from marginally high to twice or three times top normal, and all are above the labs reference range for normal.
To have quite so many abnormally high muscle enzyme results is starting to sound a little more than coincidence to me. Common links are me, my land (although one pony has barely been on grass in the last 9 months), my hay/haylage (bought in from neighbouring land), the drinking water, the way I train them (minimal stress, gradually increasing work, and beside which one of them has been retired two years, and two are only just coming into work as youngster )......
Muscle enzymes from the most recent resting bloods came back as follows:
(normal reference range: AST 100-370; CK 20-225 (with top normal of 350 being recognised by experts such as Stephanie Valberg/Sue Dyson, Beth Valentine, Dr Kellon); LDH 130-1085
Max AST 526; CK 3,578; LDH 1,261
Megz AST 362; CK 542; LDH 964
Rose AST 609; CK 913; LDH 2,130
Fox AST 622; CK 493; LDH 1,140
Zebedee AST 405; CK 331; LDH 1,422
Rock AST 418; CK 562; LDH 1,697
Im in touch with two American vets Beth Valentine (who is an expert on EPSM in draft horses) and Dr Kellon (who runs a series of online courses for horse-owners and is someone who really hunts for an answer to veterinary problems), and they have both been incredibly helpful so far. My own vets are being as helpful as they can, but they are not familiar with this type of muscle problem. Ive also been in touch with a couple of people from this board who have had ponies with muscle problems. Its probably unlikely that Ill get to the bottom of whats happening with my gang, but Im starting to wonder whether the muscle issues are environmental (ie related more to me and how I manage the ponies) or whether it is something which is found in other Dales ponies?
If anyone has experienced similar problems with their Dales pony, or had abnormally high muscle enzyme levels in their blood tests, then Id really love to hear, either on here or by pm. Muscle enzyme levels and a brief outline of any problems you noticed with the ponys performance would be really helpful.
I promise I will keep all details confidential, and will only use them to help in the management of my gang or to help experts find an answer.
Thank you!
