She's on the Forage Plus Balancer which already has magnesium oxide in it. Do I need more? If so, do I feed the 'extra' as per the tub instructions (building up slowly as Purbee suggests) or do I deduct what's already in the Forage Plus?
Youre exercising dolly 6x per week, so you know she needs more electrolytes due to that workload, hence why i wondered what mag dose was in your electrolytes youre using?
Then off the back of the total mag content of your FP balancer and electrolytes, a dose of extra mag can be worked out.
NB The rda is for ‘elemental magnesium’ - and all feed forms of mag are attached to something else, i.e mag ox is magnesium attached to oxygen….so to work out the elemental magnesium dose they are actually getting we need to know the forms of mag theyre receiving…if its only mag ox…then as an example, the 13g daily would give (roughly) 9g ‘elemental’ magnesium…when we deduct off the ’bound oxygen weight’.
With a horse in considerable work their needs for minerals/electrolytes will increase quite dramatically due to harder work than maintenance of standing about stuffing their faces!
