You are probably already aware- but I did'nt realise until I was told, so thought I might pass on the knowledge- The scoop NAF provide is twice the dose you are suppose to feed!! So half a scoop is the correct amount!
There was a thread on this a few weeks ago that I can't find now, but someone pointed out this discrepancy between the dosage and the measure on the spoon - BUT the dosage is in milligrams and the measure on the spoon in millilitres (or the other way round - can't remember) - anyway, a full spoon is the right maintenance measure.
My boy has been a bit fussy with his feed with Magic in it, but I feed only a small amount a day (about half the amount recommended) and then up to larger amount a few days before competitions.
I split it between 2 feeds and like some people have already said the scoop and the RDA is confusing!!! Why dont they make a scoup that is marked easily i.e. 1 days allowance for 16hh+ etc...does that make sense?
