Cattle need magnesium to reduce the risk of hypomagnesaemia (grass staggers or grass tetany) but magnesium salts are bitter and not readily taken by cattle. Cattle High-Mag however provides a highly palatable form of magnesium readily consumed even by grazCrystalyx Cattle High-Mag is a high magnesium lick that is designed to help maintain normal blood magnesium levels in beef and dairy livestock during periods of risk. The quality of the magnesium and the method in which Cattle High-Mag is produced means that it is highly palatable and digestible. Magnesium Supplementation: Cattle are in most need of magnesium supplementation during Spring and Autumn months. When grass is typically fast growing and lush, however it usually contains high levels of potassium which reduces magnesium availability. Cattle must include magnesium in their diet in order to maintain normal blood magnesium levels during these risk periods, magnesium salts are a way of providing a source of magnesium, but they are bitter and not readily taken by cattle. Crystalyx Cattle High-Mag however provides a highly palatable form of magnesium that is readily available with every lick that the cow takes. Research at Glasgow University (School of Veterinary Medicine) has confirmed that the high digestibility and availability of the magnesium sources used in Crystalyx Cattle High-Mag ensures that normal blood magnesium levels are maintained when target intakes are achieved. Costing between 14p and 19p per day, Crystalyx Cattle High-Mag is convenient and economical to use.ing cattle in spring and the high digestibility and availability confirmed by Glasgow Veterinary School ensures the risk of hypomagnesaemia can be significantly reduced by feeding Cattle High-Mag.
