The effects of phytase beyond phosphorus release are termed extra-phosphoric effects of phytase. The main effect of phytase is the improvement of phosphorus availability through the discharge of phosphorus from phytate.
But, phytate also forms stable complexes with proteins and minerals such as zinc, calcium, and iron from the digestive tract and prevents nutrient absorption. There are many firms like feedworks that provide the best phytase enzymes.

Thus, the extra-phosphoric effects of phytase are regarding the improvement of the digestibility of energy, amino acids, and minerals throughout the dissociation of such complexes.
The extra-phosphoric effects of phytase supply economic benefits in diet and enhance the value of dietary phytase. Using phytase above normal levels appears to have the potential to boost growth performance beyond what's expected with sufficient phosphorus levels.
The precise mode of action of elevated phytase levels remains unidentified, but it is believed to be related to extra-phosphoric effects due to higher degradation of phytate.
The greater degradation of phytate eliminates the majority of the antinutritional effects of phytate, further enhancing amino acids, digestibility of energy, and minerals.
The use of elevated levels of phytase seems to have the potential to get a greater effect on nursery pig performance, with less evidence for an effect on grow-finish pig operation.
Moreover, the effects of elevated phytase levels seem to be greater if the levels of calcium, phosphorus, and other minerals are marginal from the diet.
