Phytate as an anti-nutrient for poultry and swine

Phytate has direct anti-nutritional effects for poultry and swine, causing reductions in performance by lowering amino acid and mineral absorption and increasing endogenous losses. To evaluate this antinutritional effect is not as simple, any change in the diet to reduce phytate concentration will result in other modifications in diet composition that may also interfere with animal performance. One alternative is to use high levels of phytase in the diet, looking for the phytase to hydrolyse and
