Dr. Elleanor Kellon is one of the Dr.s who feels that all horses are lacking. It doesn't really seem to matter about the area of the country. I think I've read somewhere that the soil is now defficient because of acid rain over the past century.
Wasn't really speaking of evaluating magnesium in the blood panels. I was curious if supplementing adequate amounts (after determining through lab tests on the food intake) would affect the blood panel for other values. I don't feed any alfalfa or legumes. But, my pasture does have quite a lot of clover which ups the calcium (I believe......it's been a while). My horses get 24/7 pasture (Pacific NW, so much of the year it's pretty rich), Timothy hay, Vits/Mins and Flax Seed (more calcium there, too). I came across the mag. defficiency thoughts last year when my horses got very cresty on their pasture. Dr. Kellon suggested making sure the calcium/magnesium was balanced for my horse's food intake. I did that and the crestiness went away. The, I started reading more about calcium and have started supplementing myself. I notice a big difference in several areas of my life after trying to balance my intake, also. My boyfriend, who is a marathon runner, has also noticed a HUGE difference in his performance as well as alleviating muscle cramps that he use to experience, since upping his magnesium to match his calcium (men have different requirements than women). I do believe there is a pretty strong downside of feeding too much magnesium. It does cause greater calcium absorption and *can* cause the soft tissues (blood vessels and organs) to calcify. Although, it does take quite a lot to do that. Sorry for the sloppy paraphrasing below. I was in a bit of a hurry :-) Karen --- Susan Garlinghouse <[EMAIL PROTECTED]> wrote: > > I know most horses are deffecient in Magnesium > (many, > > severely). > > There are certainly some horses that would be, > depending on the ration and > area of the country, but why do you feel most are? > And, just out of > curiousity, what would you consider to be severely > deficient? > > > Since ATP bonds to magnesium and ATP is > > what supplies energy to the muscles, I'm wondering > if > > supplementing magnesium on a daily basis would > help, > > in anyway, to improving blood panels on horses at > > endurance rides. > > Well, blood is actually a fairly poor indicator of > magnesium status.
