The diet is balanced to meet the animal requirements of energy and digestible amino acids.\nMultiphase feeding with a diet formulation adapted to the specific requirements of the production period.\nThe feed mix matches the animal requirements more accurately in terms of energy, amino acids and minerals, depending on the animal weight and/or production stage.\nAddition of controlled amounts of essential amino acids to a low crude protein diet.\nA certain amount of protein-rich feedstuffs is substituted by low-protein feedstuffs, in order to further reduce the crude protein content. The diet is supplemented with synthetic amino acids (e.g. lysine, methionine, threonine, tryptophan, valine) so that there is no deficiency in the amino acid profile.\nUse of authorised feed additives which reduce total nitrogen excreted.\nAuthorised (according to Regulation (EC) No 1831/2003 of the European Parliament and of the Council substances, microorganisms or preparations such as enzymes (e.g. NSP enzymes, proteases) or probiotics are added to feed or water in order to favourably affect feed efficiency e.g. by improving the digestibility of feedstuffs or affecting the gastrointestinal flora.",
