The European Union does not use a unified nutrient requirement. A manufacturer committee called FEDIAF (European Pet Food Industry Federation) makes recommendations for cats and dogs that members follow. Both AAFCO and FEDIAF publish in two formats: one in the amount-per-kilogram form above, another in an energy-ratio format.
