Interactions of calcium, phosphorus, magnesium and vitamin D that influence their status in domestic meat animals.

摘要: Known and possible interactions between Ca, P, Mg, parathyroid hormone (PTH), calcitonin (CT), vitamin D its metabolites, of each these with other factors plus complexities variations within domestic animal species, such as age, sex, physiologic state (i.e., pregnancy, lactation growth) diet, make P Mg metabolism extremely dynamic complex. Many advances have been made in understanding how is controlled, secreted or metabolized the body. Some among are discussed detail, mostly a view to mechanisms by which homeostasis maintained. Also, three major diseases mineral cattle (milk fever, grass tetany wheat pasture poisoning) provide excellent models study complex soil, plant interrelationships that influence control ultimate utilization minerals animals. These used illustrate some many
