One of the main objectives in poultry husbandry is efficient and sustainable production. Several factors such as raw material prices and increasing worldwide competition force farmers to optimize their production cycles.
The search for renewable phosphate sources started when the prices of inorganic feed phosphates increased, and supply maintained to be irregular. Furthermore, environmental pollution related to the use of inorganic phosphorous cleared the path to a plant-based solution.
Phytic acid is the principal storage form of phosphorus in plant seeds and exists in nearly all ingredients derived from plant material. Particularly in oilseeds and cereals, up to 90% of total phosphorus is present in the form of phytate.
Besides being a phosphorus store, phytic acid functions as an energy store, as a source of cations and as a source of myoinositol (a cell wall precursor). However, due to the lack of suitable gastrointestinal enzymes, phytate is nearly indigestible by pigs and poultry.
