As an international forum for hypothesis-driven scientific research, the Journal of Animal Physiology and Animal Nutrition publishes original papers in the fields of animal physiology, biochemistry and physiology of nutrition, animal nutrition, feed technology and preservation (only when related to animal nutrition). Well-conducted scientific work that meets the technical and ethical standards is considered only on the basis of scientific rigor. Research on farm and companion animals is preferred. Comparative work on exotic species is welcome too. Pharmacological or toxicological experiments with a direct reference to nutrition are also considered. Manuscripts on fish and other aquatic non-mammals with topics on growth or nutrition will not be accepted. Manuscripts may be rejected on the grounds that the subject is too specialized or that the contribution they make to animal physiology and nutrition is insufficient. In addition, reviews on topics of current interest within the scope of the journal are welcome. Authors are advised to send an outline to the Editorial Office for approval prior to submission.
