Determination of the energy values of feedstuffs for swine is a difficult and tedious task. Originally, energy values were estimated from studies with chicks or were calculated for Total Digestible Nutrients (TDN) (National Research Council, 1971). Since the original direct determinations of energy in feedstuffs for pigs by Diggs et al. (1959, 1965) and Tollett (1961), the database has grown. A summary of energy values of feedstuff from around the world has been compiled by Ewan (1996). Still, where data are not available by direct means from pig studies, energy concentrations can only be estimated from chemical composition of the feedstuff. Prediction equations that have been used for estimating energy concentrations in feeds are given in the subsequent sections. In all of these equations, the energy and nutrient concentrations are expressed on a dry mater basis.
