Animal Feed Enzyme Phytase
Phytase is the third generation of phytase, which is a single enzyme preparation using advanced liquid submerged fermentation technology and processed by unique aftertreatment technology. It can hydrolyze phytic acid to release inorganic phosphorus, improve the utilization rate of phosphorus in feed, and reduce the use of inorganic phosphorus sources, and promote the release and absorption of other nutrients, reducing the cost of feed formulation; At the same time, it can also reduce the emission of phosphorus in animal feces and protect the environment. It is a green and environmentally friendly feed additive.
Formula feed, concentrated feed and premix for various types of animals.

PHYTASE EFFECTS
- Significantly improve the biological utilization rate of phytic acid phosphorus in the diet by 40% - 70%, reduce the use of inorganic phosphorus such as calcium hydrogen phosphate and bone meal, reduce the cost of feed formulation, reduce dust pollution of calcium hydrogen phosphate, and reduce the possibility of calcium hydrogen phosphate fluorosis or microbial contamination of bone meal.
- After reducing the amount of calcium hydrogen phosphate added, use the remaining formula space to increase the amount of low-price raw materials, reduce the amount of high-price raw materials used, or use formula software to optimize nutrients to further reduce formula costs.
- Improve the biological utilization rate of mineral elements, protein, amino acids, starch, etc. in feed.
- Increase the average daily weight gain (2% - 10%) and average food intake of livestock and poultry, and improve production performance.
- Reduce phosphorus excretion by about 50% to protect the environment.
Phytic acid and its anti nutritional effects
Phytic acid is a chemical compound combined by phosphate radical and inositol, it is widely found in plant feeds. It is the main storage form of phosphorus in plant seeds. The phosphorus stored in the form of phytic acid in grains and oilseeds accounts for 50% to 80% of total phosphorus (Table 1). Due to the fact that phytase is hardly secreted in the digestive tract of animals, phytate phosphorus cannot be decomposed into inorganic phosphorus for use. This phosphorus in the form of phytic acid is not only not used by animals, but also can affect the digestion and absorption of other nutrients, posing a serious threat to the environment.

Properties of Phytase
- Advanced enzyme bacteria
Green phytase is the third generation phytase, developed by our company in cooperation with famous universities abroad.
2. Advanced production technology and equipments
Advanced liquid submerged fermentation technology (Figure 1) and equipment (Figure 2), with unique aftertreatment processes.

3. Wide Work pH Range:
The optimum pH is 2.2-6.0, pH is 2.2-6.5 (Figure 3) when relative enzyme activity>50%, it has high activity in the crop and anterior stomach of poultry (pH 4-5) and in the stomach of pigs (pH 3-4, full of food).
4. Good stability
1) Stable production: After standardized treatment, the enzyme activity of different batch enzyme is stable; Each batch of enzymes is subject to enzyme activity testing during warehousing and delivery.
2) Storage stability: Enzyme activity is stable under long-term storage conditions (Figure 4);
FIGURE 3 PHYTASE ENZYME ACTIVITY CHANGE UNDER DIFFERENT pH VALUE FIGURE 4 PHYTASE STORAGE STABILITY
3) Usage stability: Phytase has strong resistance to animal endogenous pepsin and trypsin in the gastrointestinal tract of livestock and poultry (FIGURE 5), It ensures that there is sufficient enzyme activity to degrade phytic acid, and metal ions have a small impact on GREEN phytase activity (FIGURE 6), resulting in strong storage stability in feed.

Instruction:
In different animal formulas, the replacement ratio of calcium hydrogen phosphate should be controlled at:
Laying chicken and ducks: no more than 50% in summer and no more than 60% in other seasons; Dairy piglets and laying ducks: 35%;
Growth-finishing pigs, sows, broilers, meat ducks, egg breeding poultry: 50%;
If the substitution amount in the table exceeds this ratio, the reduction amount of calcium hydrogen phosphate and the addition amount of stone powder will be calculated using this ratio as the upper limit.
