　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for the renewal of authorisation of ammo nium chloride (Amoklor ?) as a zootechnical additive for all ruminants, dogs and cats and its extension of use in sows for urinary health. The applicant provided evidence that the additive currently in the market complies with the existing co nditions of authorisation. There is no new evidence that would lead the FEEDAP Panel to reco nsider its previous conclusions. Thus, the Panel co ncludes that the additive remains safe for ruminants other than lambs for fattening, lambs for fattening, cats and dogs, co nsumers and the enviro nment under the current authorised co nditions of use. Inhalation exposure of the additive is co nsidered very likely. Amoklor ?should be co nsidered a potential respiratory sensitiser but not a skin sensitiser. The additive is not irritant to the skin, but the Panel could not co nclude on its eye irritation potential. The present application for renewal of the authorisation does not include a proposal for amending or supplementing the co nditions 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 co ntext of the renewal of the authorisation. Regarding the extension of use in sows, the FEEDAP Panel co ncludes that the additive is safe and efficacious for sows at the inclusion level of 5,000 mg/kg feedingstuffs from week 9th to 11th of gestation and from week 15th of gestation to 1st of lactation.
