Grass tetany is a nutrition problem for grazing beef and dairy animals, primarily during cool seasons with highly fertilized grass and cereal crops. Tetany occurs when cattle are unable to absorb enough magnesium from their feed stuffs to support a normal magnesium level in the blood serum. Magnesium is especially important for certain enzyme and metabolic reactions in the animal’s body. This two-page publication offers information on occurrence and symptoms, causes, and recommendations for prevention and treatment—including the importance of contacting your veterinarian as soon as possible at the first sign of symptoms.
