Magnesium deficiencyis usually thought to be the cause of grass tetany, but the sodium-potassium ratio may be equally important. Feeding high levels of magnesium (as found in early season forages) can depress ruminants' serum magnesium. Free choice feeding of salt may be the key to controlling grass tetany.
