RE: [RC] question on selenium levels.... - Kathy Kelly
That seems like a pretty big range, I question the .5.
Gabriel has had Se deficieny issues this past year. Susan G said his serum levels should be between .2 and .3 since he's an endurance horse.
He's tested at .15 and after 3 mos of Se supplementation and rest at an even lower.1 (drat)! So now he's on the liquid Se-E supplement MegaSel that is supposed to work well. In addition, he still get some selenium yeast (organic form that is also supposed to be easily utilized, and after our yeast discussion I am glad to have some yeast in his diet).
He has been doing well with moderate 50s, even 2 days at 2 multiday rides even tho he's still testing low. I will have him retested again in the next few months and if he's still low we'll try an Se injection, as I want his levels up before we attempt our 1st 100 this year (hopefully!).
Friends horse has had two tie ups in past several weeks....about hour after starting work....horse was walked two and a half miles then started slow trotitng up slight hill...cramped up about a half mile up....both times was able to (had to) walk back to trailer....last trip she hauled him to vet to draw blood....don't have values yet on muscle enzymes....here is Se level:
Lisa (vet) left message on phone that Jeep's selenium level was 0.29. Reference/normal range is between 0.08-0.5, with Jeep's level right in the middle.
