A hardy new grass called "HiMag" may help protect cattle, sheep, and goats from an affliction known as grass tetany. When ruminants�animals with four stomachs�have too little magnesium in their blood, grass tetany can result. Also known as hypomagnesemia, grass tetany causes an estimated $50 to $150 million in livestock production losses each year in the United States.
