  "text": "In order to reduce total nitrogen excreted and consequently ammonia emissions while meeting the nutritional needs of the animals, BAT is to use a diet formulation and nutritional strategy which includes one or a combination of the techniques given below.\nA description of the techniques is given in Section 4.10.1. Information on the effectiveness of the techniques for ammonia emission reduction can be taken from recognised European or international guidance e.g. UNECE guidance document on ‘Options for ammonia mitigation’.\nTechnique\nApplicability\na\nReduce the crude protein content by using an N-balanced diet based on the energy needs and digestible amino acids.\nGenerally applicable.\nb\nMultiphase feeding with a diet formulation adapted to the specific requirements of the production period.\nGenerally applicable.\nc\nAddition of controlled amounts of essential amino acids to a low crude protein diet.\nApplicability may be restricted when low-protein feedstuffs are not economically available. Synthetic amino acids are not applicable to organic livestock production.\nd\nUse of authorised feed additives which reduce the total nitrogen excreted.\nGenerally applicable.\nTable 1.1\nBAT-associated total nitrogen excreted\nThe lower end of the range can be achieved by using a combination of techniques.\nThe BAT-associated total nitrogen excreted is not applicable to pullets or breeders, for all poultry species.\nThe upper end of the range is associated with the rearing of male turkeys.\nParameter\nAnimal category\nBAT-associated total nitrogen excreted (kg N excreted/animal place/year)\nTotal nitrogen excreted, expressed as N.\nWeaners\n1,5-4,0\nFattening pigs\n7,0-13,0\nSows (including piglets)\n17,0-30,0\nLaying hens\n0,4-0,8\nBroilers\n0,2-0,6\nDucks\n0,4-0,8\nTurkeys\n1,0-2,3\nThe associated monitoring is in BAT 24. The BAT-associated total nitrogen excreted levels may not be applicable to organic livestock production and to the rearing of poultry species not indicated above.",
