Description
A method for calculating the energetic feed value, based on the digestible nutrients and on the relations of the utilisation of the energy of the nutrients (carbohydrates = 100) for ATP syntheses is described. This relative scale is a nominal feed value (NFV). It characterises the ATP potential of the feedstuffs and is therefore equivalent to the efficiency of utilisation of the feed energy in the catabolic metabolism (non-thermal maintenance, muscular work (movement)) and energy costs for syntheses as well as the productive performance as energy retention in animal products. Therefore this scale secures a precise precognition of the animal performance and regulation of production for all kinds of ruminants and direction of production with the exception of the chemical heat regulation under special environmental and production conditions. The NFV can be transmitted for practical use in the other adopted and country-specific units. A general compatibility between the various feed evaluation systems could be achieved.
