  • 摘要:The additive QuantumTM is an enzyme preparation containing 6-phytase produced by fermentation of a genetically modified strain of the yeast Pichia pastoris. The efficacy and safety of this product for chickens for fattening, laying hens, turkeys for fattening, ducks for fattening and piglets (weaned), including the assessment of the safety for the consumer, the user and the environment as well as the safety aspects of the genetic modification, have already been previously assessed by EFSA. The applicant is now asking for a modification of the terms of authorisation of the feed additive when used in turkeys for fattening, by reducing the minimum recommended dose from 1000 FTU/kg to 500 FTU/kg. Based on the results obtained in three studies, the FEEDAP Panel concluded that the additive QuantumTM has the potential to improve phosphorus utilisation in turkeys for fattening at the minimum dose of 500 FTU/kg.
