  • Efficacy of a feed additive consisting of 6-phytase produced by Komagataella phaffii CGMCC 12056 (APSA PHYTAFEED® 20,000 GR/L) for pigs for fattening (Andrés Pintaluba S.A) [Elektronski vir]
    EFSA Panel on Additives and Products or Substances used in Animal Feed (Parma)
    Following a request from the European Commission, EFSA was asked to deliver a scientific opinion onthe efficacy of 6-phytase produced by the genetically modified strainKomagataella phaffiiCGMCC12056 ... (APSA PHYTAFEED®20,000 GR/L) as a zootechnical feed additive (functional group: digestibilityenhancers) for pigs for fattening at a minimum recommended level of 1,000 U /kg feed. In a previousassessment, three trials were submitted; one of them showed significant improvements onzootechnical parameters supporting the efficacy of the additive. The other two trials evaluatingapparent faecal phosphorus digestibility and bone mineralisation, showed no improvements onphosphorus retention in bone and, therefore, the FEEDAP Panel could not conclude on the efficacy ofthe additive. The applicant submitted two new efficacy studies in pigs for fattening evaluating theanimal’s zootechnical performance, apparent faecal phosphorus digestibility and bone mineralisation.One of the trials was not considered due to high rates of mortality, culling of animals and medicaltreatments applied. In the other trial, significant improvements onfinal body weight and apparent totaltrack phosphorus digestibility were found in the animals that received the phytase at 1,000 U/kgcomplete feed. Owing to the lack of sufficient data, the FEEDAP Panel could not conclude on theefficacy of the additive in pigs for fattening.
