Approximately 60-70% of the phosphorus (P) in feed plant seeds is bound to phytic acid and cannot be utilized by swine and poultry species. The enzyme phytase releases P from the phytate makes it digestible to the animal. By using feedstuffs rich in phytate-P and adequate phytase dosages complete inorganic P-free feeding of pigs from weaning to slaughter seems possible.
