  Magnesium bolus

  • For the aid in prevention of grass staggers
  • Key use at spring grazing and autumn grazing
  • Cattle meat/milk withdrawal – zero

Opti-Mag 3 boluses are indicated for use in adult cattle as an aid in the maintenance of magnesium levels during high risk periods associated with the grazing of rapidly growing grass.

The optimum way of ensuring supplementation is through administration of a sustained release magnesium bolus.  Each bolus contains 100g of magnesium.  Administration of two boluses 2-3 days before an anticipated risk period will supply approximately 6g of magnesium per animal per day for four weeks.

Second time to use Country Farm Supplies and again found them to be very good. The quality of the item and the speed with the delivery (24 hours) was excellent. Will use this company again.
