Archives of Animal Nutrition is an international journal covering the biochemical and physiological basis of animal nutrition. Emphasis is laid on original papers on protein and amino acid metabolism, energy transformation, mineral metabolism, vitamin metabolism, nutritional effects on intestinal and body functions in combination with performance criteria, respectively. It furthermore deals with recent developments in practical animal feeding, feedstuff theory, mode of action of feed additives, feedstuff preservation and feedstuff processing. The spectrum covers all relevant animal species including food producing and companion animals, but not aquatic species. Seldom can priority be given to papers covering more descriptive studies, even if they may be interesting and technically sound or of impact for animal production, or for topics of relevance for only particular regional conditions.
