Abstract

Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of 3-phytase FLF1000 as a feed additive for chickens reared for laying and minor poultry species. Safety aspects regarding the use of this additive in feed including the safety for the consumer, for the users and for the environment have been previously evaluated by EFSA. The FEEDAP Panel considered that the new use requested by the applicant would not modify those conclusions. In the previous assessment, the Panel evaluated the safety and efficacy for chickens for fattening and laying hens. In the current evaluation, no new studies were submitted to support the safety and the efficacy in new species/categories. Therefore, the data on the tolerance and efficacy in major species previously evaluated was taken into consideration for this assessment. The results of the tolerance trial in chickens for fattening previously evaluated showed that chickens tolerated well 10-fold the maximum recommended dose. The Panel extended the conclusion reached in chickens for fattening to chickens reared for laying and extrapolated it to minor poultry species for fattening purposes or reared for laying/breeding. In the previous assessment, the FEEDAP Panel concluded that the additive has a potential to be efficacious in chickens for fattening at 500 FTU/kg feed. The Panel extended the conclusion on the efficacy in chickens for fattening to chickens reared for laying and extrapolated it to minor poultry species for fattening purposes or reared for laying/breeding.
