Phytase is an enzyme that catalyzes the hydrolysis of phytic acid, a form of organic phosphorus found in plant-based feed ingredients. It plays a crucial role in the digestion and utilization of phosphorus in monogastric animals, including poultry, swine, and fish.
Phytase breaks down the phytic acid molecule into inorganic phosphorus, which can be easily absorbed by animals. This release of phosphorus is beneficial as it allows for improved phosphorus utilization and reduces the need for phosphorus supplementation in animal diets. Apart from phosphorus, phytase also aids in the enhanced availability of other important nutrients like calcium, trace minerals, and proteins from plant-based feed.
The addition of phytase to animal feed has several advantages. It helps in reducing phosphorus pollution in the environment, as the phosphorus excreted by animals can be highly detrimental if it enters water bodies, leading to eutrophication and ecological imbalances. Furthermore, phytase supplementation promotes animal growth and performance by enhancing nutrient utilization, increasing feed efficiency, and improving overall gut health.
Phytase is derived from various sources, including microbial, plant, or genetically engineered enzymes. It is commonly available in different forms, such as powder, granules, or liquid, for easy incorporation into animal feeds. The dosage of phytase varies depending on the target species, age, and diet composition.
Overall, phytase is a vital enzyme that plays a significant role in improving phosphorus and nutrient utilization, reducing environmental pollution, and enhancing animal performance.
