After calcium, phosphorus is the most present mineral in the animal organism. Fundamental in the constitution of bones, it also intervenes in the metabolism of all substances for energy maintenance.
The importance of using this salt is due to the considerable needs of calcium and phosphorus in animals and the low presence of these elements in feed and forage.
Phosphorus deficiency in forage determines weight gains below normal in cattle and the lack of production by cows up to 1000 kg of milk per year.
The main symptoms of phosphorus deficiency are anorexia, reduced fertility, rickets and osteomalacia.

Phosphate can be administered directly to the animal or mixed with common feeds and mixtures without its presence being felt.
The substance can be used alone or combined with other salts such as calcium carbonate and sodium chloride.

It is advisable to dispense phosphorus alone in the case of rations mainly consisting of legume or hay grasses or stable grass hay in which legumes are well represented; we recommend the addition of calcium carbonate in the case of maize and cornmeal, or saggine or tubers, all of which are low in calcium and phosphorus.
It is possible to dispense phosphate by adding it daily to the ration or by incorporating a certain percentage into the mass of concentrates.
