Phytate is the main store of phosphorus in vegetable feed components. Phosphorus is a key mineral that must be supplied from food to meet the needs for maintenance, growth, and development of bones.
However, phytate-bound phosphorus is largely inaccessible to pigs, with the digestibility of between 20 and 30%. Phytase enzymes also forms complexes with protein and minerals, preventing the absorption of nutrients.

Phytase is an enzyme that acts on phytates to release phosphorus in the form intended for pigs. The use of phytase in hog feed increases the absorption of phosphorus and phytate decreases the nutrient inhibitory effect.
In addition, increasing the use of phytate-bound phosphorus will reduce the environmental impact of the release of phosphorus in pig waste and minimize the use of inorganic phosphorus.
Sources of inorganic phosphorus are used in hog feed, but they are expensive and non-renewable sources. Therefore, the strategic use of phytase in hog feed can provide economic and environmental benefits.
Phytic acid is the main store of phosphorus in plants, usually in the form of phytate, and accounts for 60 to 80% of the phosphorus in plant feed components.
Corn soybean meal made from pork feed usually contains 1% phytate or 0.28% phosphorus bound to phosphorus, but the levels vary depending on the ingredients in the feed.
Phytate is considered an anti-nutrient factor for pigs because it reduces the absorption of phosphorus, energy and other nutrients in pigs.
