The Journal of Dairy Research publishes original scientific research on all aspects of the biology, wellbeing and technology of lactating animals and the foods they produce. Research Papers report innovative, hypothesis-driven research that is likely to have international impact. Research Communications are shorter and intended primarily for descriptive research and research of regional or technical impact. The Journal also publishes additional categories of Research Reviews and Research Reflections, which may be short review articles, opinion papers or hypothesis-based data-less papers. It also publishes Letters to the Editor, Book Reviews and Editorials. Research Reviews and Editorials are usually by invitation only.
