FIELD: medicine.
SUBSTANCE: there is offered a composition containing a combination of at least two phytases for hydrolysis of phytic acid (hexoctaphosphate myoinositole) to inorganic monophosphates, to phosphate myoinositole with smaller degree of phosphorylation and to free myoinositole. Said compositions are used in making a feed supplement or animal feedstuff. Also, there is offered a method of phytic acid hydrolysis with using the phytase combination. The compositions under the invention are catalysed by rapid and complete phytic acid hydrolysis in the wide range of pH values.
EFFECT: higher availability of phytic acid phosphorus and improved digestibility of animal feedstuff.
