Description
What it is. 6-phytase (EC 3.1.3.26) is a zootechnical feed additive belonging to the digestibility enhancers functional group. It is produced by fermentation of Aspergillus niger (DSM 25770) and has a minimum activity of 5,000 FTU/g, in solid or liquid form.
What it is for. This enzyme hydrolyses phytate present in plant-based feed materials, releasing phytic phosphorus in an assimilable form. It is used in feed for poultry (all avian species for laying, chickens and turkeys for fattening or breeding) and pigs (pigs for fattening, sows, weaned piglets, minor porcine species). Its use helps improve phosphorus utilisation from raw materials and adjust inorganic phosphate supplementation in formulation.
Points to watch. Minimum FTU levels set by the regulatory annex vary by species and physiological stage (for example 200 FTU for laying poultry, 100 FTU for fattening pigs, sows and minor porcine species, 125 FTU for weaned piglets up to 35 kg). Storage conditions and thermal processing stability must be respected according to the instructions for use of the additive and premixture, and personal protective equipment (skin, respiratory) is required during handling.
