Opti-Mag 3 Boluses

Opti-Mag 3 boluses aid in the maintenance of magnesium intake. Opti-Mag 3 Magnesium Boli are moulded metal cylinders containing 100g of magnesium, weighted with iron shot. For use during the high risk periods associated with grazing of rapidly growing grass, by the provision of a slow release depot of magnesium.

Administration of the Opti-Mag 3 

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.
Only to be given to cattle of at least 300 kg bodyweight. Administer orally by using the specially designed bolus gun. Load the gun by inserting the bolus into the open end. Open the animal’s mouth and the gun should then be introduced carefully and gently until the bolus is in the region of the back of the tongue. Severe pressure on the tongue should be avoided. Depression of the plunger will deliver the bolus onto the rear part of the tongue, thereby initiating a swallowing action. The gun should then be carefully withdrawn from the mouth. A second bolus should then be administered following the same procedure.
Observe each animal for a short time after administration to ensure that the boli have not been regurgitated.
