Wind and Rain High Magnesium Cattle Mineral is specially designed to meet the mineral needs of cattle grazing lush forages. These forages can be low in magnesium, which makes proper supplementation critical. Containing 4% phosphorus and 10% magnesium, essential macro and micro trace minerals, and supplemental vitamins A, D, and E, this product provides the complete mineral nutrition to address mineral deficiencies inherent in forages while supporting optimal health, fertility, and growth. Our unique manufacturing process supports more consistent intake, helping cattle receive adequate levels of magnesium every day. The formula is highly palatable, encouraging steady consumption. Wind and Rain Storm technology adds advanced weather resistance to help reduce waste. The large particle size and specialized formulation prevent the mineral from absorbing moisture or blowing out of the feeder. As a result, Wind and Rain Storm Formulas last longer and are more economical to feed than conventional loose minerals. Use only as directed.
