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 Bacillus velezensis ATCC PTA‐6737 as a zootechnical additive (functional group: gut‐flora stabiliser) in the context of the renewal of the authorisation for turkeys for fattening and turkeys reared for breeding. The applicant is also requesting to modify the target species in the current authorisations to 'all growing poultry', the increase of the recommended use level in chickens for fattening, chickens reared for laying and minor poultry species except minor poultry for laying from 1 × 107 to 1 × 108 CFU/kg complete feed and the compatibility of the additive with halofuginone. The applicant provided evidence that the additive currently in the market complies with the conditions of the authorisation. There was no new evidence that would lead to reconsider previous conclusions. Therefore, the FEEDAP Panel concluded that the additive remains safe for all poultry species for fattening and reared for laying/breeding, the consumers and the environment under the current authorised conditions of use. The additive is not irritant to the skin and eyes, but it should be considered a respiratory sensitiser. The Panel could not conclude on the skin sensitisation potential of the additive. The Panel concluded that the additive has a potential to be efficacious as a zootechnical additive for poultry for fattening and reared for laying/breeding under the proposed conditions of use.

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 efficacy of a feed additive consisting of carvacrol (Nimicoat®) as a zootechnical feed additive for weaned piglets at the recommended use level of 250 mg/kg complete feed. In a previous assessment, three efficacy trials and one tolerance–efficacy trial were assessed. Only one of the efficacy trials was considered to support the efficacy at the recommended use level. The applicant provided amendments to two previously submitted studies and a new trial. The amendments to the previously submitted studies did not change the conclusions from the previous assessment. The new efficacy study showed a significant improvement of the zootechnical parameters. Two studies showed positive and significant effects on the performance of the weaned piglets when the additive was administered at 250 mg/kg feed. Due to the lack of sufficient data, the FEEDAP Panel is not in the position to conclude on the efficacy of the additive for the target species. [ABSTRACT FROM AUTHOR]

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 Bacillus velezensis ATCC PTA‐6737 as a zootechnical additive (functional group: gut flora stabilisers) in regard to the renewal of the authorisation for weaned piglets, weaned minor porcine species, sows and minor reproductive Suidae species, and its extension of use for all Suidae. The applicant provided evidence that the additive currently in the market complies with the conditions of the authorisation. The Panel concluded that there is no new evidence that would lead it to reconsider the previous conclusions; the additive is safe for the target species, consumers and the environment under the authorised conditions of use. This conclusion also applies to the target species/categories for which a request for an extension of use is made. The Panel concluded that B. velezensis ATCC PTA‐6737 is not irritant to skin or eyes but should be considered a respiratory sensitiser due to its proteinaceous nature. No conclusions could be drawn on the skin sensitisation potential of the additive. The Panel concluded that the additive has the potential to be efficacious in all growing Suidae (suckling, weaned and fattening Suidae) at the minimum inclusion level of 1 × 107 CFU/kg of complete feed and in sows and minor reproductive Suidae species at 1 × 108 CFU/kg complete feed.

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of 6‐phytase produced by the genetically modified strain Komagataella phaffii CGMCC 12056 (APSA PHYTAFEED® 20,000 GR/L) as a zootechnical feed additive (functional group: digestibility enhancers) for pigs for fattening at a minimum recommended level of 1,000 U /kg feed. In a previous assessment, three trials were submitted; one of them showed significant improvements on zootechnical parameters supporting the efficacy of the additive. The other two trials evaluating apparent faecal phosphorus digestibility and bone mineralisation, showed no improvements on phosphorus retention in bone and, therefore, the FEEDAP Panel could not conclude on the efficacy of the additive. The applicant submitted two new efficacy studies in pigs for fattening evaluating the animal'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 medical treatments applied. In the other trial, significant improvements on final body weight and apparent total track phosphorus digestibility were found in the animals that received the phytase at 1,000 U/kg complete feed. Owing to the lack of sufficient data, the FEEDAP Panel could not conclude on the efficacy of the additive in pigs for fattening. [ABSTRACT FROM AUTHOR]

Ammonium propionate is authorised as a liquid preparation of ≥ 19% ammonium propionate, ≤ 80% propionic acid and ≤ 30% water. The applicant requested for the renewal of the authorisation of ammonium propionate when used as a feed additive for all terrestrial animal species. The applicant has provided evidence that the additive in the market complies with the conditions of the authorisation. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) confirms that the use of ammonium propionate under the current authorised conditions of use is safe for the target species, the consumers and the environment. Concerning the user safety, the additive is corrosive to skin and eyes. Any exposure is considered a risk. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation., (© 2024 European Food Safety Authority.

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 efficacy of ROVABIO® ADVANCE (liquid and solid) which contains endo-1,4-beta-xylanase and endo-1,3(4)-beta-glucanase produced with Talaromyces versatilis IMI 378536 and DSM 26702 as a zootechnical feed additive for weaned piglets at the recommended use level of 1800 U xylanase and 1250 U glucanase per kg feed. In a previous assessment, three long-term trials in weaned piglets were submitted. Two of them were considered to support the efficacy of the additive while a third trial was not further considered due to the large number of veterinary treatments applied. A new trial was provided to support the efficacy of the additive, but it did not show a significant improvement of the performance parameters at the minimum recommended use level. Due to the lack of sufficient data, the FEEDAP Panel is not in the position to conclude on the efficacy of the additive for the target species., Competing Interests: The Panel wishes to thank Jaume Galobart and Marianna Kujawa for the support provided to this scientific output.If you wish to access the declaration of interests of any expert contributing to an EFSA scientific assessment, please contact interestmanagement@efsa.europa.eu., (© 2024 European Food Safety Authority.

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 efficacy of ferrous lysinate sulfate (Plexomin® L-Fe) for all animal species. The additive has not been previously authorised as a feed additive in the European Union (EU). The safety of the additive for the target species, consumer, user and the environment has already been assessed in previous opinions. However, the efficacy remained inconclusive due to the absence of evidence of the bioavailability of the iron contained in the additive in the trials submitted either with chickens for fattening or with weaned piglets. For the present assessment, the applicant submitted a recalculation of the previous data on weaned piglets, which did not show evidence of bioavailability. Therefore, in the absence of adequate data, the FEEDAP Panel could not conclude on the efficacy of ferrous lysinate sulfate for all animal species., Competing Interests: If you wish to access the declaration of interests of any expert contributing to an EFSA scientific assessment, please contact interestmanagement@efsa.europa.eu., (© 2024 European Food Safety Authority.
