If gut capacity is limiting, feed intake may be regulated on a dry matter (or 'bulk') basis. However, if gut capacity is not limiting intake, an energetic regulation of intake may be more likely.\par

It is left to the user to express the mode of regulation of ad libitum feed intake (i.e., DM, DE, ME or ME). The choice of expressing ad libitum feed intake has consequences on the way the model predicts the response of feeding a high energy diet. For example, if ad libitum feed intake capacity is expressed on a DM basis, feeding a high energy diet will improve performance. If intake capacity is expressed on a NE basis, pigs fed a high energy diet will reduce their DM intake (to maintain an equal NE intake) without affecting performance.\par
