Formulated specifically for cows in the critical pre-calving phase, SuperCalver provides a balanced combination of macro minerals, essential vitamins, and key trace elements. The high magnesium content supports muscle and nerve function, helping stabilize the cow during late gestation and reducing the risk of metabolic issues post-calving.
Vitamins A, D₃, and E work together to strengthen immunity, enhance bone strength, and support the developing calf. A balanced calcium–phosphorus profile contributes to smoother calving, while trace minerals such as copper, cobalt, iodine, and zinc support fertility, metabolic efficiency, and overall herd performance.
Designed for daily use whether cows are grazing or housed, this block ensures consistent nutrient delivery during one of the most demanding periods of the production cycle.
