About
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.
- Antinutrient phytate and interaction with phytase
- The use of phytase in animal nutrition, i.e. “phytase matrix”
- Approaches to inorganic phosphorus-free feeding for maximized reduction of phosphorus excretion and saving of phosphate resources
