Product Spotlight: EnergiLass® SUPER HI-MAG 12

Apr 2026

Rapid spring pasture growth can increase the risk of grass tetany. Providing additional magnesium with EnergiLass Super Hi-Mag 12 can help reduce that risk this spring.

April showers bring spring pastures! This spring lush, rapidly growing pastures come with increased risk of grass tetany in grazing cattle. Grass tetany is caused by an imbalance of potassium and magnesium in the body. This commonly occurs in the spring when cool-season grasses have higher concentrations of potassium which can limit magnesium availability. This will cause cattle to have muscle stiffness, reduced performance and in severe cases, may lead to death. The risk of grass tetany can be reduced by providing additional magnesium supplementation both before and during turnout on rapidly growing pastures. EnergiLass Super Hi-Mag 12 is an effective to increase magnesium intake in cattle during this high-risk period. Designed to be fed in addition to a free-choice mineral, EnergiLass Super Hi-Mag 12 provides additional magnesium in a highly palatable form for consistent intake across the herd. It also provides added protein, vitamin and mineral supplementation to support animal health and production as nutritional demands change during the spring grazing season. Help your producers reduce the risk of grass tetany this spring by recommending EnergiLass Super Hi-Mag 12 as part of their pasture-turnout strategy.

  • Supplemental Magnesium – This product provides 15 grams of supplemental magnesium when consumed at 0.75 pounds per head daily to aid in the prevention of grass tetany.
  • Continuous Protein Delivery – Research has shown that multiple, small doses of protein help improve forage digestion. EnergiLass provides supplemental protein 24/7, helping cattle get most out of each bite. This product is ideal for medium-to-high quality forages.
  • Calcium and Phosphorus – A 2-to-1 calcium to phosphorus ratio is ideal for cattle on pasture, which tend to be deficient in phosphorus.
  • Trace Mineral Fortification – Formulated to supply key trace minerals to help support optimal animal health and performance.
  • Optimal Vitamin Fortification – Vitamins A, D and E support growth, metabolism, reproductive performance and proper immune system function.
  • No Added Salt – EnergiLass is formulated without added salt. A source of free-choice salt should be made available at all times, such as Framework 365 Mineral MG.
  • Highly Palatable – The high molasses content of EnergiLass results in a highly palatable supplement, encouraging and maintaining whole herd consumption.
  • Consistent Intake – The unique manufacturing process results in a product that cattle must lick in order to consume. This results in consistent, predictable intake that helps to manage costs per head per day.
