Efficacy of the feed additive consisting of Lactiplantibacillus plantarum (formerly Lactobacillus plantarum) CECT 8350 and Limosilactobacillus reuteri (formerly Lactobacillus reuteri) CECT 8700 (AQ02) for suckling piglets (Aquilon Cyl S.L.)

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the feed additive consisting of Lactiplantibacillus plantarum (formerly Lactobacillus plantarum) CECT 8350 and Limosilactobacillus reuteri (formerly Lactobacillus reuteri) CECT 8700 (AQ02) as a zootechnical feed additive for suckling piglets. In a previous opinion the FEEDAP Panel concluded that the additive is considered safe for the target species, the consumer, and the environment. The Panel concluded that the additive should be considered a respiratory sensitiser but could not conclude on the skin/eye irritation potential or on its skin sensitisation potential. The Panel previously could not conclude on the efficacy of AQ02. The applicant has provided supplementary information to support the efficacy of the additive in suckling piglets. Based on the data provided, the FEEDAP Panel could not conclude on the efficacy of the additive

Safety and efficacy of a feed additive consisting of l‐valine produced by Corynebacterium glutamicum CGMCC 18932 for all animal species (Xinjiang Fufeng Biotechnologies Co., Ltd.)

Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of l‐valine produced by fermentation using a non‐genetically modified strain of Corynebacterium glutamicum (CGMCC 18932). l‐Valine is intended to be used in feed and water for drinking as a nutritional additive, functional group amino acids, their salts and analogues, for all animal species and categories. The production strain is considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The FEEDAP Panel concluded that l‐valine produced by C. glutamicum CGMCC 18932 is considered safe for the target species when supplemented to the diet in appropriate amounts according to the nutritional needs of the target species. The use of l‐valine produced using C. glutamicum CGMCC 18932 in animal nutrition is considered safe for the consumer and for the environment. No conclusion could be drawn on the potential of l‐valine produced using C. glutamicum CGMCC 18932 to be irritant to the skin or eyes, or a dermal sensitiser due to the lack of data. The FEEDAP Panel concluded that the l‐valine produced by fermentation using C. glutamicum CGMCC 18932 is an efficacious source of the essential amino acid l‐valine for non‐ruminant nutrition. To be as efficacious in ruminants as in non‐ruminants, supplemental l‐valine requires protection against ruminal degradation. The FEEDAP Panel expressed concerns on the use of amino acids in water for drinking for hygienic reasons

Efficacy of the feed additive consisting of 6‐phytase (produced by Komagataella phaffii CGMCC 7.19) (Nutrase P) for chickens for fattening, other poultry for fattening or reared for laying and ornamental birds (Nutrex N.V.)

Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of 6‐phytase produced by Komagataella phaffii CGMCC 7.19 (Nutrase P) as a zootechnical feed additive for chickens for fattening, other poultry for fattening or reared for laying and ornamental birds. In a previous opinion, the FEEDAP Panel concluded on the efficacy of Nutrase P for the target species at the level of 1,500 phytase units (FTU)/kg but could not conclude at the minimum recommended use level of 500 FTU/kg complete feed. The applicant has provided supplementary information, consisting in the statistical re‐analysis of the long‐term study assessed in the original opinion, in order to support the efficacy of the additive at the minimum recommended level of 500 FTU/kg complete feed. Considering the previously submitted studies and the re‐analysis of the long‐term study, the Panel concluded that the additive has a potential to be efficacious for chickens for fattening, other poultry for fattening or reared for laying and ornamental birds under the proposed conditions of use

Assessment of the safety of the feed additives acetic acid, calcium acetate and sodium diacetate for fish (FEFANA asbl)

Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety of acetic acid, calcium acetate and sodium diacetate as technological feed additives (preservatives) for salmonids/fish. The additives are already authorised for use for all animal species other than fish. In previous opinions, the FEEDAP Panel concluded that a maximum concentration of 2,500 mg acetic acid/kg complete feed (or 1,000 mg/L water for drinking) was safe for poultry, pigs and pet animals. Ruminants were considered to exhibit a higher tolerance. Due to lack of data for salmonids, the Panel could not conclude on the safety of acetic acid and its salts for fish. The applicant has provided supplementary information consisting in a tolerance study in Atlantic salmon (Salmo salar) and a literature search to support the safety of acetic acid in fish. Considering all the available information, the FEEDAP Panel concluded that acetic acid (and its salts by analogy) is considered safe for fish up to the maximum recommended supplementation level of 2,500 mg acetic acid/kg complete feed

Safety and efficacy of a feed additive consisting of endo‐1,4‐β‐xylanase produced by Komagataella phaffii ATCC PTA‐127053 (Xygest™ HT) for all Suidae (Kemin Europa N.V)

Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of endo‐1,4‐β‐xylanase produced by Komagataella phaffii ATCC PTA‐127053 (Xygest™ HT) as a zootechnical feed additive (functional group: digestibility enhancers) for all Suidae at a recommended minimum level of 90,000 U/kg complete feed for pigs in the growing period and 45,000 U/kg complete feed for sows. The production strain is considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The FEEDAP Panel concluded that the additive is safe at the minimum recommended use level for all growing Suidae and all sows in the lactating phase. Xygest™ HT was considered safe for the consumers and for the environment when used in feed for all Suidae. The additive was considered not to be irritant to eyes and skin, but was considered as a dermal and respiratory sensitiser. In the absence of sufficient data, the FEEDAP Panel was not in the position to conclude on the efficacy of Xygest™ HT for all Suidae
