All About The Best Phytase Enzymes In Animal Feed

The most common exogenous enzyme used in monogastric feed is microbial phytase. Phytase reduces the antinutritional effects of phytate, improves the digestibility and energy of phosphorus (P), Calcium, and amino acids, and reduces the environmental impact from inorganic P excretion. The many benefits of using phytase to feed animals are well-known.

The first commercially-available microbial phytase was released in 1991. There are many types of phytases. They differ in their effectiveness. Many phytase factors can also have an impact on phytase activity. You can also search online for the best phytase enzymes to include in your animal feed.

Mode of action of Phytase

Phytic acid is made from myo-inositol through a series of phosphorylation processes. It consists of an inositol circle with six phosphate ester bonds. The salt form is known as phytate. Most phytic acids are present in the form of mixed salts. It can cause animals to have a reduced ability to digest other nutrients as well as their performance.

Myo-inositol-hexakisphosphate-phosphohydrolase (phytase) is responsible for the stepwise removal of phosphate from either phytic or salt phytate. The phytases will first hydrolyze any fully phosphorylated phytic acid to penta, tri-, and di-esters. Then they will hydrolyze the latter into tetra-esters. Hydrolysis in in-vivo will result in incomplete hydrolysis and a mixture of inositol/phosphate esters.

It is widely accepted that phytase can lower feed costs and increase the efficiency of phosphate and other nutrients used in plant-based feed ingredients. This has both economic and environmental benefits.
