My horse had Laminitis back last Oct. Then in Jan was diagnosed with Cushings. I give give her a Cal-Mag suppliment everyday.
Its really cheap on ebay!
Here goes!!..............
Calcined Magnesite is a source of Magnesium that is often deficient in grazing pastures and therefore a horses diet. Magnesium is the main ingredient of many calmers on the market, and has been shown to reduce the risk of laminitis.
Magnesium supplementation has been advised by veterinary surgeons with excellent results both in USA and the UK. The supplementation serves not only to re-balance the diet in low magnesium areas or with high cereal diets, but also to help in combating fat deposition in overweight animals (cresty necks). In particular, with laminitics, to aid weight loss where necessary, for protection of body tissues, and also to maintain circulation.
friend has a pony with chronic stress-related laminitis issues. She fed a magnesium (oxide?) supplement, for a while, then took her off it as she was simplifying her diet. The symptoms reoccured, so she swears by it now!
To be honest I would get Mag Ox nor Cal Mag. Cal Mag is like cement and can cause scouring, it's really meant for cattle. Mag Ox is finer texture.
Both are used in the prevention of laminitis, especially useful to balance the effect of rich pasture or new grass. You should still check the horse's digital pulses daily though if it is prone to lami and not rely on the Magnesium too much.
MagOx or CalMag will only help if your grazing is deficient in Magnesium so always best to get your soil analysed first. An even cheaper option of feeding MagOx daily is the product made by Equine America - Magnitude - £14.99 for a pot which is a 6 month supply for the average size horse.
