Balanced and complete mineral supplement for beef cattle on pasture targeting early season grass scenarios where increased magnesium supplementation is beneficial. CCN Mag Boost Tub is a more palatable option than loose mineral for supplemental magnesium, ensuring more consistent desired mineral intake, and consumed by the cattle’s licking action and naturally self-limiting due to the consistent nutrient density and hardness. CCN Mag Boost Tub is naturally weather resistant and reduces the risk of losing valuable mineral to wind and rain, and can aid in modifying cattle grazing patterns by strategic placement of the tubs.
