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 Lactobacillus rhamnosus CNCM I-3698 and Lactobacillus farciminis CNCM I-3699 when used as a silage additive in forage for all animal species. The additive is the result from the fermentation of milk-based broth with L. rhamnosus CNCM I-3698 and L. farciminis CNCM I-3699. It is intended to be used in easy and moderately difficult to ensile materials at a minimum proposed application rate of 2.5 × 107 and maximum 8 × 107 VFU/kg complete feed for all animal species. The data provided do not allow a full characterisation of the additive, and therefore, uncertainty remains on the nature of the product in terms of viability, on the ratio between the active agents and on the shelf-life of the additive. Both strains fulfil the requirements of the Qualified Presumption of Safety (QPS) approach to the assessment of safety and consequently, are presumed safe for the target animals, consumers of products from animals receiving the additive and the environment. The additive should be considered a respiratory sensitiser. In the absence of data, no conclusions can be drawn on the irritancy of the additive to skin and eyes or on its dermal sensitisation potential. No conclusions can be drawn on the efficacy of the additive to improve the ensiling process of easy and moderately difficult to ensile materials.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 Cygro® 10G. The active substance of Cygro® 10G is the polyether ionophore maduramicin ammonium-α, a coccidiostat intended to be used in feed for turkeys for fattening. In a former opinion, the FEEDAP Panel concluded that the efficacy of Cygro® 10G in turkeys for fattening had not been sufficiently demonstrated. In the present submission, new efficacy studies have been provided by the applicant. A positive effect of Cygro® 10G in preventing coccidiosis in turkeys was shown in three anticoccidial sensitivity tests (ASTs). However, owing to the lack of floor pen studies showing a positive effect, the FEEDAP Panel is not in the position to conclude on the efficacy of Cygro® 10G for turkeys for fattening.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 l-lysine monohydrochloride produced by fermentation with the genetically modified strain of Corynebacterium glutamicum DSM 32932. Neither the production strain nor its recombinant DNA were detected in the final product. The additive does not pose any safety concern associated with the genetic modification of the production strain. l-Lysine HCl produced by C. glutamicum DSM 32932 is considered safe for the target species, for the consumer and for the environment. l-Lysine HCl produced by C. VU661013 glutamicum DSM 32932 is not toxic by inhalation; it is not irritant to skin and not a skin sensitiser. The additive is not corrosive to eyes but it should be considered as an eye irritant. In general, l-lysine HCl is considered as an efficacious source of the essential amino acid l-lysine for non-ruminant animal species. For the supplemental l-lysine to be as efficacious in ruminants as in non-ruminant species, it would require protection against degradation in the rumen.In 2015, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) issued an opinion on the safety and efficacy of ammonium formate, calcium formate and sodium formate when used as a technological additive (preservative) for all animal species. Calcium formate was considered safe for all animal species at a maximum concentration of 10,000 mg formic acid equivalents/kg complete feed (with the exception of pigs, for which a maximum concentration of 12,000 mg formic acid equivalents/kg complete feed was considered safe). Calcium formate was also considered safe for the consumer and the environment. The Panel also concluded that calcium formate is non-irritant to the skin, but mildly irritant to the eyes, and is a respiratory irritant with a potential for sensitisation. The Panel also concluded that 'Calcium formate or solid sodium formate had no discernible effects on microbial numbers in the feed materials examined. The preservative effect of the three formate salts in water for drinking was not demonstrated'. In the current opinion, additional data to demonstrate the efficacy of calcium formate as a preservative in feed for all animal species were assessed. The Panel concluded that calcium formate has the potential to be efficacious as a preservative in feedingstuffs for all animal species at the proposed use level. In the absence of data, the Panel cannot conclude on the efficacy of the use of the additive in water for drinking.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 ammonium formate for all animal species. In 2015, the FEEDAP Panel delivered an opinion on the safety and efficacy of ammonium formate, calcium formate and sodium formate. In that opinion, the Panel considered the unavoidable presence of formamide, as a contaminant of ammonium formate, of concern for developmental toxicity for reproduction animals and for carcinogenicity for non-food-producing animals. Regarding the safety for the consumer, the Panel concluded that the use of the additive in dairy animals and laying poultry may raise concerns due to the potential exposure of consumers to formamide. In the current submission, the applicant proposed to reduce the maximum content of ammonium formate in feed to 2,000 mg formic acid equivalent/kg feed from the previously proposed 12,000 mg/kg for pigs and 10,000 mg/kg for all other animal species. Based on the calculation of the maximum safe concentration of formamide in feed, the FEEDAP Panel cannot conclude on the safety of ammonium formate in complete feed for laying hens and sows, since the calculate maximum concentration of formamide in feed (11.5 mg formamide/kg) exceed the maximum safe concentration in feed for these species (5.6 mg formamide/kg for laying hens and 9.9 mg formamide/kg for sows). Based on the results of a residue study in eggs, the use of ammonium formate in animal nutrition at a maximum content of 2,000 mg formic acid equivalent/kg complete feed would not result in concerns on the safety for the consumer.
