普通玉米富含植酸，然而家禽、猪等单胃动物不能吸收植酸中的磷素，玉米中大多数的磷通过动物的粪便排泄，常常又被雨水直接携带至河道，造成污染。过量的磷素使水体中的藻类迅速生长，消耗水中的氧，造成水体中的鱼类和其他生物窒息而死。通过特定的酶处理食料可以增加单胃动 Ordinary corn is rich in phytic acid. However, monogastric animals such as poultry and pigs can not absorb phosphorus in phytic acid. Most phosphorus in corn is excreted through animal excrements and is often carried directly to the watercourse by rainwater, causing pollution. Excess phosphorus causes algae in the water to rapidly grow and consume oxygen in the water, causing the suffocation of fish and other organisms in the water. Treating foodstuffs with specific enzymes can increase monogastric activity
