    A total of 22 young goats were used to assess the effect of two organic zinc sources, i.e. Zn lactate and Zn chelate, compared with Zn oxide and a control treatment without Zn supplementation on meat quality and zinc concentration in muscle. Muscle pH and colour (L*– lightness, a* – redness, b* – yellowness) were determined in the triceps brachii muscles, immediately after slaughter and chilling (24 h). Zn content, chemical composition (dry matter, fat, protein and collagen content), drip losses, cook losses, hardness, cohesiveness, pH (48 h) and colour (48 h) were determined. We did not found statistical significant differences in meat quality between treatments. Significant difference was found in concentration of Zn only between control and group receiving Zn oxide (P < 0.05)

    Safety and efficacy of a feed additive consisting of Bacillus velezensis PTA‐6507, B. velezensis NRRL B‐50013 and B. velezensis NRRL B‐50104 (Enviva® PRO 202 GT) for turkeys for fattening (Danisco Animal Nutrition)

    [EN]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 the additive consisting of Bacillus amyloliquefaciens PTA-6507, B. amyloliquefaciens NRRL B-50013 and B. amyloliquefaciens NRRL B-50104 (trade name: Enviva® PRO 202 GT) for turkeys for fattening. The product under assessment is based on viable spores of three strains originally identified as B. amyloliquefaciens which, in the course of the current assessment, were reclassified as Bacillus velezensis. The bacterial species B. velezensis is considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The identity of the active agents was established. The active agents do not harbour acquired antimicrobial resistance genes and lack toxigenic potential and the capacity to produce aminoglycosides. Following the QPS approach, the three bacterial strains are presumed safe for the target species, consumers and the environment. Since no concerns are expected from the other components of the additive, Enviva® PRO 202 GT is also considered safe for the target species, consumers and the environment. Enviva® PRO 202 GT is non-irritant to skin and eyes and is not a dermal sensitiser. Due to the proteinaceous nature of the active agents, the additive should be considered a respiratory sensitiser. In a previous opinion, it was concluded that Enviva® PRO 202 GT has a potential to be efficacious as a zootechnical additive in chickens for fattening at the recommended level of 7.5 × 107 CFU/kg complete feed. It is considered that conclusions on efficacy of Enviva® PRO 202 GT in chickens for fattening can be extrapolated to turkeys for fattening. Therefore, the FEEDAP Panel concludes that Enviva® PRO 202 GT has the potential to be efficacious in turkeys for fattening at 7.5 × 107 CFU/kg complete feed.S

    Safety of the fermentation product of Aspergillus oryzae NRRL 458 (Amaferm®) as a feed additive for dairy cows (Biozyme Inc.)

    [EN] Amaferm® is a fermentation product produced by Aspergillus oryzae NRRL 458, containing alpha-amylase and cellulase enzyme activities, authorised for use as a feed additive for dairy cows. In 2016, the applicant requested for the renewal of the authorisation and the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) issued an opinion at that regard in 2020. In that opinion, the Panel could not confirm the previously drawn conclusions (EFSA, 2006) regarding the safety of the production strain, and consequently could not confirm the safety of the additive for the target species and consumers. In the current submission, the applicant provided supplementary information that allowed the Panel to conclude on the identity of the production strain, redefine the specifications of the additive, and finally to conclude on its safety. Therefore, the new data provided permit to conclude that Amaferm® complies with the conditions of the authorisation. However, the Panel noted that there is the need to change the specification and description of the cellulase and amylase units in the authorisation act. The data provided in the previous (EFSA FEEDAP Panel, 2020) and the current assessments support that Amaferm® remains safe under the approved conditions for target species, consumers and the environment. The additive is non-irritant to skin and eyes, or a dermal sensitiser but should be considered a potential respiratory sensitiser.SIThe Panel wishes to thank the following for the support provided to this scientific output (in alphabetical order of the last name): Working Group on Animal Nutrition and Working Group on Microbiology, Rosella Brozzi, Christina Cuomo and Jordi Tarres Call

    Safety and efficacy of a feed additive consisting of lactic acid produced by Weizmannia coagulans (synonym Bacillus coagulans) DSM 32789 for all animal species except for fish (Jungbunzlauer SA)

    ©2022EuropeanFoodSafetyAuthority.EFSAJournalpublishedbyWiley-VCHGmbHonbehalfofEuropeanFoodSafetyAuthority.[EN] 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 lactic acid produced by a non-genetically modified strain of Weizmannia coagulans (synonym of Bacillus coagulans) (DSM 32789) for all animal species except for fish. The production strain qualifies for the QPS approach for safety assessment. Although uncertainty remains concerning the possible presence of viable cells and/or spores of the production strain in the final product, this does not raise safety concerns for the target species, humans and the environment. The lactic acid is safe at 50,000 mg/kg complete feed for functional ruminants and pigs and at 20,000 mg/kg feed for all the other animal species and categories except for pre-ruminants for which a safe level cannot be established. The corresponding safe levels in water for drinking would be 15,000 mg/L water for pigs and 8,000 mg/L for other non-ruminant species. Although no safe concentration of lactic acid in water for drinking for ruminants can be derived, the Panel considers that the use in water for drinking is safe in ruminants when the total daily intake of the additive does not exceed the daily amount that is considered safe when consumed via feed. The use of the additive under assessment in animal nutrition is considered safe for the consumers and for the environment. It is considered corrosive to the skin, eyes and mucous membranes. Lactic acid is used in food as a preservative. It is reasonable to expect that the effect seen in food will be observed in feed when it is used at comparable concentrations and conditions. However, the FEEDAP Panel has reservations about its effectiveness as a preservative in complete feed with a moisture content of ≤ 12%.SIThe Panel wishes to acknowledge the contribution to this opinion of Martina Reitano, Joana Revez, the experts of the Microbiology and of the Animal Nutrition Working Groups of the FEEDAP Panel

    Assessment of the efficacy of a feed additive consisting of Limosilactobacillus reuteri (formerly Lactobacillus reuteri) DSM 32203 for dogs (NBF LANES)

    Get PDF
    Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of Limosilactobacillus reuteri (formerly Lactobacillus reuteri) DSM 32203 as a zootechnical additive for dogs. The additive is a preparation of viable cells of L. reuteri DSM 32203 and it has not been previously authorised as a feed additive in the European Union. The additive is intended for use in complete feed for dogs at a minimum use level of 6 x 10(9) colony forming units (CFU) per animal and day. In a previous opinion, the FEEDAP Panel could not conclude on the efficacy of L. reuteri DSM 32203 for dogs. The applicant has provided supplementary information to support the efficacy of the additive to dogs. Based on the data provided, the FEEDAP Panel concludes that L. reuteri DSM 32203 has the potential to improve faecal consistency by reducing the moisture content of stools from dogs receiving the additive at 1 x 10(10) CFU/kg feed. However, the Panel has some reservations on the effects in the moisture content of stools, which if maintained over time might cast doubts on the benefits on the long-term use of the additive since it could lead to constipation

    Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of a product consisting of Limosilactobacillus reuteri (formerly Lactobacillus reuteri) DSM 32264 as a zootechnical additive for cats. The additive is a preparation of viable cells of L. reuteri DSM 32264 and it has not been previously authorised as a feed additive in the European Union. The additive is intended for use in complete feed for cats at a minimum inclusion level of 6 9 109 colony forming units (CFU) per animal and day. In a previous opinion, the FEEDAP Panel could not conclude on the efficacy of L. reuteri DSM 32264 for cats. The applicant has provided supplementary information to support the efficacy of the additive for cats. Based on the data provided, the FEEDAP Panel concluded that L. reuteri DSM 32264 has the potential to improve faecal consistency by reducing the moisture content of stools from cats receiving the additive at 1 9 1010 CFU/kg feed. However, the Panel had some reservations on the effects in the moisture content, which if maintained overtime, might cast doubts on the benefits on the long-term use of the additive since it could lead to constipation

    Safety and efficacy of a feed additive consisting of Pediococcus pentosaceus IMI 507025 for all animal species (ALL‐TECHNOLOGY (IRELAND) LIMITED [Alltech Ireland])

    [EN] 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 Pediococcus pentosaceus IMI 507025 as a technological additive for all animal species. The additive is intended to improve the production of silage at a proposed application rate of 1 × 109 colony forming units (CFU)/kg fresh material. The bacterial species P. pentosaceus is considered by the European Food Safety Authority to be suitable for the qualified presumption of safety approach. As the identity of the strain has been established and no antimicrobial resistance determinants of concern were detected, the use of the strain as a silage additive is considered safe for livestock species, for consumers and for the environment. In the absence of data, the FEEDAP Panel cannot conclude on the potential of the additive to be a skin/eye irritant or a skin sensitiser. Given the proteinaceous nature of the active agent, the additive should be considered a respiratory sensitiser. The additive at the proposed application rate of 1 × 109 CFU/kg fresh material has the potential to improve the fermentation of the silages from easy to moderately difficult to ensile foragesS

    Safety and efficacy of a feed additive consisting of l‐valine produced by Corynebacterium glutamicum CGMCC 7.366 for all animal species (Ningxia Eppen Biotech Co., Ltd.)

    [EN] 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 the feed additive consisting of l-valine produced by fermentation using a non-genetically modified strain of Corynebacterium glutamicum (CGMCC 7.366). The additive is intended to be used in feed and water for drinking 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 concludes that l-valine produced using C. glutamicum CGMCC 7.366 is safe for the target species when supplemented in appropriate amounts to the diet according to the nutritional needs of the target species. The FEEDAP Panel has concerns on the use of amino acids in water for drinking for hygienic reasons, and due to the risk of imbalances when administered simultaneously via feed. The use of l-valine produced using C. glutamicum CGMCC 7.366 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 7.366 to be toxic by inhalation, irritant to the skin or eyes, or a dermal sensitiser due to the lack of data. The additive l-valine produced by fermentation using C. glutamicum CGMCC 7.366 is regarded as an efficacious source of the essential amino acid l-valine for non-ruminant nutrition. For the supplemental l-valine to be as efficacious in ruminants as in non-ruminant species, it requires protection against degradation in the rumenSIThe Panel wishes to acknowledge the contribution of Jaume Galobart, Yolanda Garc ıa Cazorla and Lucilla Gregoretti to this opinio

    [EN] 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 additive consisting of Ligilactobacillus animalis (formerly known as Lactobacillus animalis) ATCC PTA-6750 when used as a technological additive (acidity regulator, preservative and hygiene condition enhancer) in feed and water for drinking for all animal species. The product is intended for use as a single strain at a minimum inclusion level of 5 × 106 CFU/L or CFU/kg in water, liquid and dry feeds. No minimum inclusion level is proposed by the applicant when used in combination with other microbial technological additives. The bacterial species L. animalis is considered by EFSA to be eligible for the qualified presumption of safety approach. As the identity of the strain has been clearly established and it did not show acquired resistance to antibiotics of human and veterinary importance, the use of the strain in animal nutrition is considered safe for the target species, consumers and the environment. No conclusions can be drawn on the skin/eye irritancy or skin sensitisation potential of the product, but it should be considered a respiratory sensitiser. Exposure of users by inhalation is likely. The Panel is not in the position to conclude on the efficacy of L. animalis ATCC PTA-6750 when used in animal nutrition as an acidity regulator, preservative or hygiene condition enhancer due to lack of data. The studies provided showed that L. animalis ATCC PTA-6750 when used in combination with Propionibacterium freudenreichii ssp. shermanii ATCC PTA-6752 has the potential to act as an acidity regulator. However, the Panel has reservations on the effects of this mixture in practical use conditionsSIThe Panel wishes to acknowledge the contribution of Yolanda Garc ıa Cazorla to this opinio
