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 of 3‐phytase FLF1000/FSF10000 as a feed additive for pigs for fattening and minor porcine species for growing. This additive contains 3‐phytase produced by a genetically modified strain of Komagataella phaffii and it is authorised in its liquid FLF1000 and solid form FSF10000 as a feed additive for chickens for fattening, laying hens, chickens reared for laying and for minor poultry species for fattening or reared for laying or for breeding. The FEEDAP Panel has adopted an opinion regarding the use of this product as a feed additive in pigs for fattening and minor porcine species for growing. In that opinion, the FEEDAP Panel concluded that the use of the product as a feed additive would raise no concerns for the consumer safety nor for the environment but that the additive should be regarded as a potential respiratory sensitizer. The Panel also concluded that the additive has a potential to be efficacious in improving the phosphorus utilisation in the target species. However, the Panel could not conclude on the safety for the target species due to the limitations identified in the data provided. The applicant has now complemented the information and made it available to the Panel. The tolerance trial was done in weaned piglets in which the animals received up to 10 times the recommended dose of 1,000 FTU/kg feed. The results showed no adverse effects of the phytase on the performance of the animals or on the haematological and biochemical parameters measured in blood. Therefore, the Panel concluded that the additive (3‐phytase FLF1000 and FSF10000) is safe for pigs for fattening and minor growing porcine species at the recommended dose of 1,000 FTU/kg feed.

- Abstract
Following a request from the European Commission, the EFSA 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 Axtra®XAP 104 TPT as a zootechnical feed additive (digestibility enhancers) for poultry species. The additive contains three enzyme activities (endo‐1,4‐beta‐xylanase, protease and alpha‐amylase) produced by three different genetically modified strains. Viable cells and recombinant DNA of the strains producing the protease and amylase were not detected in the final product. Owing to the insufficient data, uncertainty remained on the presence in the additive of viable cells of the strain producing the xylanase. The results obtained in the genotoxicity and subchronic oral toxicity studies performed with the three fermentation products did not indicate safety concerns resulting from the fermentation products used in the formulation/manufacturing. However, uncertainties remain on the suitability of the test item used in the studies conducted with the xylanase; therefore, the Panel was not in the position to conclude on the toxicological potential of AXTRA®XAP 104 TPT. Consequently, the Panel could not conclude on the safety of the additive for the target species, consumers and users. Owing to the uncertainty on the presence of viable cells of one of the production strains in the additive, the Panel could not conclude on the safety for the environment. The FEEDAP Panel concluded that AXTRA®XAP 104 TPT is efficacious in chickens for fattening, chickens reared for laying and minor poultry species up to the point of lay at the level of 2,000 U xylanase, 200 U amylase and 4,000 U protease per kg feed. Owing to the lack of sufficient data, the Panel could not conclude on the efficacy of the additive for laying hens. [ABSTRACT FROM AUTHOR]

Following a request from the European Commission, the EFSA 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 APSA PHYTAFEED® 20,000 GR/L (6‐phytase) as a zootechnical feed additive for laying hens and other poultry species for laying. The additive is a preparation of 6‐phytase produced by a genetically modified strain of Komagataella phaffii and has been previously assessed by the FEEDAP Panel in the context of three applications for its use in different species/categories. The Panel concluded in those opinions that the production strain is safe, and that the use of the additive as a feed additive would raise no safety concerns for the consumers and the environment. The additive was also considered not to be irritant to skin or eyes or a dermal sensitiser but it should be considered as a respiratory sensitiser. The Panel considered that the new use in laying hens and other poultry species for laying would not modify the previously drawn conclusions with respect to the consumers, users and the environment. A tolerance trial in laying hens and a subchronic oral toxicity study were made available to support the safety of the additive for the target species/categories subject of this new application; from the results obtained, the Panel concluded that the additive is safe for laying hens at the recommended level of use (300 U/kg feed) with a wide margin of safety and therefore the conclusion was extrapolated to other laying birds. The FEEDAP Panel concluded that the additive has the potential to be efficacious in laying hens at the level of 300 U/kg feed and this conclusion was extrapolated to other laying birds.

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 Belfeed B MP/ML as a feed additive for sows in order to have benefits in piglets and for all porcine species. This additive contains endo‐1,4‐β‐xylanase produced by a genetically modified strain of Bacillus subtilis and it is authorised in the European Union as a feed additive for poultry for fattening, weaned piglets and pigs for fattening. The applicant requested the extension of use of the additive to sows in order to have benefits in piglets and to all porcine species at any developmental stage at 10 IU/kg feed. The FEEDAP Panel concluded that there are no concerns for consumer safety and no risks for the environment are expected from the use of Belfeed B MP/ML in all Suidae species. The additive is not irritant for skin or eye but it should be considered a potential respiratory sensitiser for the users, the Panel could not conclude on the potential of the additive as a potential dermal sensitiser. Considering the results from a tolerance trial done in weaned piglets, those in a subchronic oral toxicity study and the nature/origin of the product under assessment the Panel concluded that the additive is safe for all porcine species at any developmental stage. The data previously assessed in piglets and pigs for fattening allowed to conclude that the additive is efficacious at 10 IU/kg feed in suckling piglets and all Suidae species from suckling to slaughter. The data submitted to support the efficacy for sows was considered insufficient and therefore the Panel could not conclude on the efficacy in sows. [ABSTRACT FROM AUTHOR]

PHYZYME®XP 5000 G/L is a feed additive that contains 6‐phytase produced by a genetically modified strain of Schizosaccharomyces pombe. The applicant requested for the renewal of the authorisation for PHYZYME®XP 5000 G and L to be used as a feed additive in chickens for fattening, laying hens, turkeys for fattening, ducks for fattening, piglets (weaned), pigs for fattening and sows. This scientific opinion concerns the renewal of the authorisation of the additive for those species. To support the request, the applicant provided evidence that the additive in the market complies with the conditions of the authorisation. According to the information provided by the applicant, no new evidence has been identified that would make the FEEDAP Panel reconsider the previous conclusions regarding the safety for the target species, consumer, user and environment. The application for renewal of the authorisation did not include a proposal for amending or supplementing the conditions of the original authorisation that would have an impact on the efficacy of the additive. Therefore, there was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation. [ABSTRACT FROM AUTHOR]

The additive Hemicell®‐L is a liquid preparation of endo‐1,4‐β‐mannanase that is authorised as a zootechnical feed additive for chickens for fattening. The applicant has requested the renewal of the authorisation, new uses and the modification of the manufacturing process including the change of the production strain. The new production strain is a genetically modified strain of Paenibacillus lentus obtained from a strain that has been evaluated previously by EFSA and considered to be safe. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) evaluated the genetic modification and concluded that the sequences introduced to obtain the production strain did not raise safety concerns. The production strain and its DNA were not detected in the additive. The Panel concluded that the additive is safe for chickens for fattening and turkeys for fattening at the recommended level. These conclusions were extended or extrapolated to the other target species under application. The Panel concluded that the results obtained in the toxicological studies performed with the fermentation products of the recipient strain and of another genetically modified strain obtained from the same recipient strain could support the safety for the consumer of the product obtained with the new production strain. The additive is not a dermal or eye irritant and it is not a dermal sensitiser. However, considering that the active substance is a protein, the additive should be regarded as a potential sensitiser. The Panel concluded that the additive has a potential to be efficacious as a zootechnical additive for the target species at 79,200 U/kg. [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 the safety and efficacy of HOSTAZYM® X as a feed additive for rabbits for fattening. HOSTAZYM® X contains endo‐1,4‐beta‐xylanase produced by a strain of Trichoderma citrinoviride and is available in liquid and solid formulations. It is authorised as a feed additive for chickens for fattening, turkeys for fattening, laying hens, minor poultry species for fattening and laying, weaned piglets, pigs for fattening and carps. The applicant has now requested to extend the authorisation to rabbits for fattening. The FEEDAP Panel considered that the new use of the additive would not change the previous conclusions regarding the safety for the consumer, user and environment. There are no concerns for consumer safety and no risks for the environment are expected from the use of the additive as a feed additive. Regarding the safety for the user, the additive should be considered a potential skin and eye irritant, and a potential skin and respiratory sensitiser. A subchronic oral toxicity study in rats was submitted to support the safety of the additive when administered to rabbits for fattening. The maximum safe enzyme activity in feed for the rabbits for fattening was derived from the data obtained in the subchronic oral toxicity study in rats; considering the maximum safe intake derived for rabbits from the toxicological data, the FEEDAP Panel concluded that the additive is safe for rabbits for fattening at the recommended use level. Two efficacy studies were submitted to support the efficacy of the additive; a significant effect of the additive in a relevant parameter was found in only one trial. Due to the insufficient evidence the Panel could not conclude on the efficacy of the additive in rabbits for fattening. [ABSTRACT FROM AUTHOR]

FEED additives , *PIGLETS , *FOOD production , *TRICHODERMA , *CHICKENS - Abstract
The product Bergazym® P100 contains a xylanase which is produced by a non‐genetically modified strain of Trichoderma reesei. The additive is available in a coated granular form and it is intended to be used as a zootechnical additive (functional group: digestibility enhancers) for chickens for fattening, and weaned piglets at the dose of 1,500 EPU/kg feed. The production strain and the additive were fully characterised in a previous assessment of the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel). In that assessment, the FEEDAP Panel concluded that the additive is safe for chickens for fattening, weaned piglets and pigs for fattening and that the use of this product as a feed additive raises no concerns for consumers of food products obtained from animals receiving it or for the environment. The FEEDAP Panel also concluded that the additive is not irritant to skin or eyes but should be considered as a potential skin and respiratory sensitiser. The Panel evaluated the efficacy of the additive and concluded that it has a potential to be efficacious in pigs for fattening at 1,500 EPU/kg feed. However, the Panel could not conclude regarding the efficacy of the additive for chickens for fattening and weaned piglets due to insufficient data/information. The applicant has now provided supplementary information in order to complement the information available supporting the efficacy of the additive. With the newly submitted efficacy studies and clarifications, the Panel concluded that the additive has a potential to be efficacious in chickens for fattening and weaned piglets at 1,500 EPU/kg feed.

A tolerance study was submitted to support the safety of the additive in the new target species/category. The results showed that sows tolerated well a 100‐fold the recommended enzyme activity level in feed. Consequently, the FEEDAP Panel concluded that the additive is safe for sows at 1,500 EPU/kg feed. A total of four studies were submitted to support the efficacy of the additive, one of which was not considered further in the assessment due to the high mortality registered in piglets. In the other three, a significant and positive effect on a relevant parameter was found in only one trial. Therefore, the Panel concluded that there is insufficient information to conclude on the efficacy of the additive. [ABSTRACT FROM AUTHOR]
