Description
Norbrook Opti-Mag 3 Boluses
Slow-Release Magnesium Boluses for Grazing Cattle
Norbrook Opti-Mag 3 Boluses provide a convenient, slow-release source of magnesium to help maintain magnesium intake in cattle during periods when the risk of deficiency is increased. Each bolus contains 100g of magnesium and is specially formulated to release approximately 3g of magnesium per day, helping to support cattle grazing rapidly growing spring grass.
Designed for use before and during high-risk grazing periods, Opti-Mag 3 Boluses offer an effective way to provide a continuous source of magnesium without the need for daily supplementation.

Benefits
Maintaining adequate magnesium intake is particularly important during periods when cattle are grazing lush, fast-growing pasture, as magnesium levels obtained from grass may not always meet requirements. Norbrook Opti-Mag 3 Boluses provide a practical, long-lasting source of magnesium, reducing the need for frequent supplementation and helping support normal nutritional management throughout higher-risk grazing periods.
Directions for Use
Administer two Opti-Mag 3 boluses per animal two to three days before the anticipated period of risk, such as before moving cattle from housing onto spring pasture.
If continued supplementation is required, treatment may be repeated no later than four weeks after the initial administration.
Only administer using a suitable bolus applicator.
