Phosphorous

Phosphorous is part of the structural substance in bones and teeth and works in fine interplay with calcium. Phosphorous is also found in every cell as a component of the cell membrane and DNA molecules. Other molecules that absorb and release energy during metabolic processes also contain phosphorous, e.g. ATP (adenosine triphosphate).

The daily requirement of a warmblood is approximately 12 to 14 grams of phosphorous. For the horse’s health, the correct calcium-phosphorous ratio (Ca:P ratio) in feeding is crucial: it should not fall below 1:1 or exceed 3:1.

Pregnant mares and foals have a higher requirement for phosphorous. The calcium-phosphorous ratio should be somewhat closer here. Ordinary horse hay just about covers the phosphorous requirement of adult horses. Grains such as oats or barley, but above all wheat bran, linseed and brewer’s yeast, are rich in phosphorous.
