Phosphorus

Phosphorus (P) is a macromineral that, like Calcium, is found in highest amounts in bone It is also required for energy production and the synthesis of many vital compounds such as DNA Because Phosphorus is present in high amounts in cereal grains, especially wheat bran, some horses receive too much Phosphorus and not enough Calcium then develop problems To avoid this, first make sure the horse's diet meets at least the minimum recommended NRC levels of both Calcium and Phosphorus, then make sure the ratio between the two is somewhere in the 1:1 to 2:1 range
