摘要

Ronozyme? P/Bio‐Feed? Phytase/ZY? Phytase is a 6‐phytase produced by Aspergillus oryzae carrying a gene coding for phytase from Peniophora lycii . The safety of the genetic modification of the current production strain has been previously established by EFSA in 2004. The product is available in two forms: granulate and liquid, providing 5000 FYT/g and 20000 FYT/g, respectively. The liquid and solid forms of the additive are considered to be equivalent when used to deliver the same enzyme levels. Based on tolerance studies performed in chickens and turkeys for fattening, laying hens, ducks, piglets, pigs for fattening and sows, the FEEDAP Panel concludes that the additive is safe for those target species at the maximum proposed dose of 1000 FYT/kg complete feed. The FEEDAP Panel considers that these conclusions can be extended to all poultry (fattening and laying) and porcine species (growing and breeding) at the same maximum dose. The data previously assessed are considered to provide sufficient evidence that this product presents no risks for the consumer, user or the environment. The data provided allow drawing conclusions on the efficacy of the additive when supplemented to diets deficient in available P at the level of 250 FYT/kg complete feed for chickens and turkeys for fattening, 300 FYT/kg for laying hens, 500 FYT/kg for piglets and pigs for fattening and 750 FYT/kg for sows. These conclusions can be extended to the corresponding minor species.
