Journal of Dairy Science® Receives Impact Factor of 3.5 as Journal Industry Adjusts to New Calculation Model

JDS maintains a robust suite of impact metrics and a commitment to continued influence and growth

Champaign, August 1, 2023 The Journal Impact Factor is one tool among many used to assess the quality of scientific journals and reflects the average number of article citations during the preceding two years. According to new statistics released in Clarivate’s Journal Citation Reports™, the Journal Impact Factor for the Journal of Dairy Science (JDS) is 3.5, meaning the typical JDS article was cited 3.5 times in 2020 and 2021. A new method of calculating impact factors has caused deviations for many journals but JDS remains near the top in the Agriculture, Dairy, and Animal Science category.

In years past, the impact factor calculation was done using an article’s print or issue publication date. In June 2022, Clarivate moved to a new calculation that uses the much-earlier electronic publication date. This new model will take several years to fully take effect, causing discrepancies between citation counts and the number of articles used in the impact factor calculation. The JDS impact factor has been increasing consistently over the past decade. The slight dip in the current JDS impact factor compared with last year can be explained by the changes to the calculation of the impact factor. JDS maintained a robust five-year Impact Factor of 4.2, indicating that its articles continue to be cited and influence the dairy industry well beyond the immediate two-year period following publication. The journal also saw an increased Article Influence score—a metric comparable to the Journal Impact Factor that considers the significance of citations as well as the number.

The Journal of Dairy Science, published by Elsevier and FASS Inc., remains a leading platform for disseminating trusted and pioneering research in dairy production and foods, and continues to have a strong suite of impact metrics. JDS remains in the top 10 for the Agriculture, Dairy, and Animal Science category (9th out of 62 journals) and in the top 50% (Q2) for the Food Science and Technology category (56th out of 142 journals). JDS articles published between 2019 and 2022 received 27,769 citations, placing JDS in the top 3% of journals for the number of citations for its subject field. JDS holds a SCImago Journal & Country Rank (SJR)—a score based on both number of citations as well as the prestige of the journals in which those citations appear—of 1.179 and has placed in the top 25% (Q1) for Animal Science and Zoology since 1991. Additionally, JDS is an important source of information for application in the dairy industry.

“The field of academic publishing, just like dairy science, continues to change and innovate. While we understand the changes, our editors, staff, and reviewers also remain first and foremost committed to rigorous peer review, continuous improvements to our processes, and transparent and ethical publishing practices to best serve our community of dairy scientists,” said Editor-in-Chief Paul Kononoff, PhD, of the University of Nebraska. “We remain committed to being a high-impact journal by all measures.”

Since 1917, JDS has been a leading peer-reviewed general dairy research journal and an indispensable resource for dairy professionals worldwide. While the journal has long been posting articles electronically prior to their issue dates, in April 2023, the journal began streamlining its production process to reduce the time—from months to weeks—from acceptance to publication.

“Shortened production time is a benefit to our authors, who will be able to more rapidly share their research findings. It will also support early career scientists, who can now document their publication accomplishments in an even more timely manner. The change also benefits our readers, who will gain faster access to articles describing the cutting-edge research, innovations, and breakthroughs published in JDS,” Kononoff added. “As always, we are laser-focused on ensuring the journal the best it can be and excited for our continued growth and improvement for the benefit of the world’s dairy sector.”
