NE-22 Mag has all the benefits of NE-22, but with 2.0% added magnesium to help combat grass tetany. NE-22 Mag is a Nutritionally Engineered® high protein supplement that is heavily fortified with vitamins and trace minerals designed to support animals on good quality forages or whenever a protein supplement is needed. NE-22 Mag is ideal for cattle grazing rapidly growing grasses in late winter or early spring, especially lactating cows, who might be at risk for grass tetany. NE-22 Mag is ideal for herds that are not receiving minimum nutrient requirements from forages alone. In addition to offering 22% protein, NE-22 is highly fortified with vitamins A, D, and E, and contain up to 125% of NRC trace mineral requirements. Phosphorus is typically one of the first limiting nutrients for grazing cattle. NE-22 contains 2% added phosphorous to help balance out pastures that are low in phosphorus. Important for bone development and cell energy, cattle short on phosphorous will show fragile bones, poor growth, low appetite, chewing of wood/hair/bones, poor reproductive performance, and reduced milk production.
