feeds. Moreover, the properties of a specific constituent reflects the processing history of that
specific ingredient. By relating pellet quality to physico-chemical properties, e.g., functionality of

diet ingredients. Objective criteria from animals are still necessary to evaluate pellet quality as far
as nutritional quality is concerned. 0 1998 Elsevier Science B.V.
