Metadata about: The concept of total digestible nutrients comes from the old system of measuring available energy of feeds and energy requirements of animals involving a complex formula of measured nutrients. It is very hard to measure, but is used widely in some parts of the U.S. and Canada. TDN values are usually quoted as percentages for feeds and as amounts per day for requirements. The values are usually calculated on feed analysis reports. The simplest and most commonly used formula for estimating TDN is TDN = DE/0.044. One kilogram of TDN is equivalent to 4.4 megacalories of DE.
