Calcium and phosphorus have long been recognized as mineral elements that are seriously deficient in cereal grains and plant by-products. However, some questions arise as to the availability of these minerals, particularly phosphorus, in cereal grains and by-products and the requirements of swine for these minerals. Evidence of lameness of growing-finishing swine is often associated with a calcium or phosphorus problem in the ration although these minerals may or may not be a factor related to this condition. This experiment was conducted to study the effects of com-soybean meal rations containing varying levels of added calcium and phosphorus on growth performance, carcass characteristics and levels of calcium and phosphorus in the blood serum of growing-finishing swine.
