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.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 iron chelates of lysine and glutamic acid (Iron-LG) as nutritional feed additive for all animal species. The European Commission request followed an opinion of the FEEDAP Panel published in 2019; in that opinion the Panel could not conclude on the efficacy of the additive. The applicant submitted additional information to allow the FEEDAP Panel to complete its assessment; these additional data, related to the efficacy of the additive, are the subject of this opinion. Three studies were provided, one each with weaned piglets, pigs for fattening and laying hens. In the study in laying hens, improvements in iron content in egg yolk, iron in serum and in other iron-related blood endpoints were observed. Based on the results of this study, the FEEDAP Panel concluded that the additive is a source of bioavailable iron, comparable to the standard inorganic iron source, and therefore, the additive is efficacious in meeting the animals' requirements; the results of the study in pigs for fattening supported the bioavailability of Iron-LG. The conclusion drawn by the Panel could be extrapolated to all animal species and categories.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 for the environment and efficacy of DSP ® (a mixture of disodium salt of ethylenediaminetetraacetic acid (Na2 EDTA), tannin-rich extract of Castanea sativa, thyme oil and origanum oil) as a zootechnical feed additive for pigs for fattening. The European Commission request followed an inconclusive opinion of the FEEDAP Panel published in 2016. Eganelisib ic50 The applicant submitted additional information to allow the FEEDAP Panel to complete its assessment; these additional data, related to the safety for the environment and the efficacy of the additive, were the subject of this opinion. Concerning safety for the environment, the risk quotient (PEC/PNEC) value for aquatic organisms was less then 1, indicating no concerns of DSP ® for the aquatic compartment; no toxicity data for terrestrial organisms were provided and consequently no conclusion on the safety of DSP ® for the terrestrial compartment could be reached, as well as on the risk for groundwater contamination. Based on the results from three studies in pigs for fattening in which final body weight and average daily weight gain were increased, and feed to gain ratio was improved, the FEEDAP Panel concluded that DSP ® has the potential to be efficacious as a zootechnical additive in pigs for fattening.The additive sorbitan monolaurate consists of sorbitol (and its anhydrides) esterified with fatty acids derived from coconut oil. It is currently authorised in the European Union and it is intended to be used as a technological additive (functional group of emulsifiers), in feedingstuffs for all animal species, at a maximum concentration of 85 mg/kg complete feed. In 2019, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) issued an opinion on the safety and efficacy of sorbitan monolaurate. Owing the lack of data, the FEEDAP Panel could not conclude on the safety of the additive for the environment. The applicant submitted new data (fate and degradation as well as ecotoxicity data) that were evaluated in the present opinion. The absorption, distribution, metabolism and excretion of structurally related compounds (sorbitan monostearate and sorbitan trioleate) indicate that the additive is expected to be partially metabolised. In addition, sorbitan monolaurate and some related compounds are readily biodegradable. The limited available data on the effects of sorbitan monolaurate in marine crustaceans and in marine sediment indicate that the ecotoxicity of the additive is low, in consistency with the very low acute toxicity of sorbitan esters. Overall, the FEEDAP Panel concludes that a risk of sorbitan monolaurate to terrestrial and aquatic environment is unlikely. Therefore, no safety concerns for the environment are expected from the use of the additive under assessment according to the established 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 safety and efficacy of OptiPhos PLUS ®, intended to be used as a feed additive for laying hens, turkeys for breeding, chickens for breeding, minor poultry species for egg production purposes and breeding. The active substance is 6-phytase produced by a genetically modified strain of Komagataella phaffii. The EFSA FEEDAP Panel concluded that the genetic modification of the production strain does not give rise to safety concerns. Based on the tolerance studies provided, the Panel concluded that the additive is safe for the target species under the conditions of use with a wide margin of safety. The additive was considered safe also for the consumer and the environment. The additive is not a skin irritant but is a dermal sensitiser. The FEEDAP Panel could not conclude on the eye irritation potential of the additive. Owing to the proteinaceous nature of the active substance, the additive is considered a respiratory sensitiser. The FEEDAP Panel concluded that the additive has the potential to be efficacious in increasing the phosphorus utilisation in laying hens at the level of 250 FTU/kg feed. These conclusions were extended to turkeys for breeding and chickens for breeding and extrapolated to minor poultry species for egg production purposes and breeding.
