In Europe, energy evaluation systems, based on digestible (DE), metabolisable (ME) or net (NE) energy values, are used to describe energy contents in feed ingredients for pig nutrition (GfE, 2006). Most energy values in feed ingredients for growing pigs were obtained in studies in which the feed intake was restricted, although ad libitum feeding regime represents on-farm feeding conditions. Moreover, in post weaning piglets, the voluntary feed intake is highly variable (Brooks and Tsourgiannis, 2003). There is evidence, that high levels of feed intake can reduce ileal protein and amino acid digestibility in growing pigs and piglets (Moter and Stein, 2004; Goerke et al., 2009), due to a limited capacity of the gastrointestinal tract for protein and amino acid digestion and absorption (Li et al., 1993). The effect of a wide range in feed intake levels on the contents of digestible and metabolisable energy in diets for piglets has not yet been determined
