For use during the high risk periods associated with grazing of rapidly growing grass, by the provision of a slow release depot of magnesium.
Two Opti-Mag 3 Boli should be given to each animal two or three days before the expected period of risk, e.g. before transfer from indoors to grass in the spring. If necessary repeat no later than four weeks.
1 bolus delivers 3g per day
