Mijn ervaring is net als die van fanci_mike en freeride: het is echt verschrikkelijk om in essentie hele fijne, talentvolle paarden aan PSSM1 ten onder te zien gaan. Zelf heb ik er eentje lopen die ik niet meer rijd omdat ze chronische trillingen in haar rug heeft. Dat is mild symptomatisch. Ze is ook zwaar symptomatisch geweest en dat is hartverscheurend geweest. Voor wie daar meer gevoelig voor is voeg ik er nog even aan toe dat het oplappen en goed houden van een PSSM positief paard ook zeer doet in de portemonnee!
En ja, ik ken er ook die onder goed management niet te onderscheiden zijn van gezonde paarden, maar een PSSM1 paard is aantoonbaar niet goed in de spieren, dus waarom zou je dat door willen fokken?? Vooral binnen een ras als de Tinker zijn er voldoende fokdieren voorhanden die het niet hebben. Waarom dan doorfokken met een genetisch defect?
Bij de Belgen is het een groter probleem vwb fokken omdat daar het percentage positieven heel erg hoog ligt en het aantal dubbel positieven ook aanzienlijk is. Waarschijnlijk vanwege hun spiervezeltype en het werk waar ze normaal gesproken voor gebruikt worden hebben zij er minder last van. Ik zeg minder, omdat er wel degelijk ook symptomatische koudbloeden zijn.
Voor diegenen die zeggen "maar mijn paard is niet symptomatisch en loopt Grand Prix dressuur" ... hier is een interessant verhaal over een non-symptomatisch paard:
Tracey WinterisComing Stark op Facebook schreef:Well had an interesting occurrence today. The mare I posted about that boards with me, Weaver's Lena Miss, had her first big episode today. She's fat, sassy, and pretty much a pasture ornament since her teenage owner lost interest. So we were moving her to the other farm and she decides she doesn't want to load. Has a little bitch fit and sits back and rears up. Not a biggie, spoiled horses don't bother me. She comes down, gets all snorty ( this was how she got her owners to put her up) and rears up again. Right at the top of the rear PSSM hits. I am not kidding you, the muscles spasm hit her hind legs and she fell over flat to her side, gasping and having tremors. Her head thankfully smacked down on the rubber mats we have at the front of the barn. She laid on her side twitching, hind legs out like she was having a stroke and RIPPLES going up and down the big muscles in her forearm and haunches. She finally got up, staggered around and coughed and wheezed and then slowly came back to reality. It was NOT a stroke. There was no facial paralysis, no blood shot membranes and it went away as fast as it had hit.
Scared one of my students, my husband wigged out because he'd never seen an episode before in 23 years of being around horses.
So now the little mare is in a stall, cooled down, medicated and obviously NOT going anywhere any time soon so I can monitor her.
Which brings me to this: There is NO fricking way anyone should be breeding this crap forward. This horse has never had a symptom, never given ANY indication she wasn't 100%. She was literally being stressed less than weanling a foal. She's 2007 horse, so mature enough and had been ridden and worked that she COULD have shown symptoms before now, but didn't.
I do NOT want to hear that someone's horse hasn't every shown any signs as an excuse to breed positive horses. This mare had never shown a single damn symptom. I was going to lease her for breeding prior to testing her. I let my kid ride her to keep her legged up. There is NO fricking way I would have let my child on a horse that was positive if I had known. This episode freaked me out because of the implications. It was proof that it can happen any time and any place. This mare could have thrown a fit at a show, on the trail, at the vet, walking around the pasture. It didn't matter that she was fed correctly, that she has adequate exercise, good vet care, good farrier care. She's well bred ( except for that whole PSSM gene) and if you looked at her standing in front of you you'd think she was the picture of health and good breeding. If she had flipped over on my kid or the teenager that owned her I would have died of shame and I didn't even know the mare had it until tested!

Overigens zijn er mensen vanuit de Paintwereld bezig om te onderzoeken of het mogelijk is het importeren van positieve paarden te verbieden. Ik juich het toe
