VemoZyme® F is a phytase ezyme preparation with activity of min 5000 phytase units per gramme (for VemoZyme® F 5000) and min 10000 phytase units per gramme (for VemoZyme® F 10000). One phytase unit corresponds to the quantity enzyme preparation, needed to release 1 μmol inorganic phosphorus from sodium phytate per 1 minute at temperature 37°C and pH 5.0.

VemoZyme® F 10000 is a phytase enzyme preparation with activity of min 14 000 FTU/g and VemoZyme ® F 5000 is with activity of min 7 000 FTU/g. One phytase unit FTU is defined as the amount of enzyme which liberates 1 micromole inorganic phosphorus per minute from sodium phytate at pH 5.50 and 37.0°C and under the specific conditions of the assay.


Enzyme Characteristics 

VemoZyme® F shows highly efficient enzyme activity in a wide range of pH from 2.0 to 6.0. The product is thermostable and keeps stable activity during storing, homogenizing and granulating (Тable 1).



About 60 - 85% of the total phosphorus in cereals, pulses and oilseed crops can not be assimilated by non-ruminants, because it exists in the form of phosphorus phytate.

The phosphoric groups in phytic acid are electronegative, and have very strong chelating capacity with some cations, such as Ca2+, Mg2+, Zn2+, Cu2+, Mn2+, Fe2+, K+ etc., thus influencing the absorption and utilization of these minerals by livestock.

The phosphoric groups in phytic acid can also combine with cation groups on proteins, amino acids, starch and lipids in feed and reduce their solubility, thus influencing the digestibility of these nutritional materials by livestock.

Phytic acid can also combine with enzymes in the animal's body such as amylase, pepsin, trypsin, acid phosphatase, etc. It reduces the activity of these enzymes, resulting in a decreased utilization rate of ration nutrients.

Phytate is a major anti-nutrition factor in the feed of monogastric species. It can reduce the utilization rate of feed phosphorus and other nutrients by animals.

The utilization of phosphorus from phytate becomes possible with the addition of phytase enzyme, because animals do not produce this enzyme themselves. The application of phytase is a well-known method for degrading phytate complexes and utilizing the phytate phosphorus from plants.

Biological Action

The use of phytase has tremendous biological, economical and ecological benefits:
♦    Increases phosphorus phytate utilization rate of feed by 40%~60%
♦    Increases the utilization rate of calcium, zinc, copper, magnesium and other minerals
♦    Increases the utilization rate of proteins, amino acids, starch and lipids in the feed
♦    Decreases the addition of inorganic phosphorus with 6-8 kg per ton feed
♦    Decreases the phosphorus content in the animal's excrements and the pollution of the environment


VemoZyme® F 5000
♦    100-150 g/t feed for pigs and poultry (500 - 750 U/kg) 
♦    60-90 g/t feed for laying hens (300 - 450 U/kg)

VemoZyme® F 10000
♦    50-75 g/t feed for pigs and poultry (500 - 750 U/kg) 
♦    30-45 g/t feed for laying hens (300 - 450 U/kg)


In dry and cool places away from heat and direct sunlight

Experimental Data

VemoZyme® F in poultry feed

VemoZyme® F in pig feed

By increasing the utilization of phosphorus and nutrients in the compound feed, VemoZyme® F improves production performance and at the same time helps protect the environment.


Experimental design
Positive Control: Diet with balanced content
of dicalcium phosphate (DCP)
Test Group 1: Diet with reduced content of DCP +
VemoZyme® F (500 U/kg)
Test Group 2: Diet with reduced content of DCP +
VemoZyme® F (750 U/kg)

VemoZyme® F in poultry feed

The use of VemoZyme® F allows to reduce the content of dicalcium phosphate in the compound feed by 44%. In all groups supplemented with VemoZyme® F has been found lower phosphorus content in the excrements, compared to the control group. The addition of VemoZyme® F helps to reduce the cost of compound feed by about 4%, estimated according to the economic situation at the time of the survey.
