Ex: cu, zc, i: involved in complex biochem rxns: Iron essential constituent of hemoglobin (blood) and myoglobin (muscle) Other mins, such as ca, k, mg, and na, involved in activity of nervous system. Na, k, and cl involved in regulation of osmotic pressure and ph in an animal"s body fluids. Stand up straight: largest amts of minerals occurs in skeleton and provides its structural rigidity. Ca, p, mg major mins in skeleton. Ca and p ~75% of mins in an animal"s body. Requirements and deficiencies: essential macro-mins most commonly deficient/ imbalanced in livestock rations are ca, mg, na, and p. Clinical signs and symptoms vary bw species: deficiency of ca or p or vit d, or an imbalance can result in rickets in young animals, mild to severe p deficiencies aren"t uncommon in grazing species--pica.
