Peer Review Process

Peer review is the scrutiny of the author's scholarly research and other experts in the same field to check the work's validity and evaluate its suitability for publication. The Online Journal of Animal and Feed Research follow a double-blind peer-reviewing procedure by at least 2 reviewers who are not part of the journal’s editorial staff and mostly suggested by section editors. This method of review provides a fair, unbiased, independent, critical assessment of the submissions and more effectively conveys the assessment of expert reviewers to authors, readers, and other interested parties (upon corresponding author's agreement).

Peer review is intended to improve the accuracy, clarity, and completeness of published manuscripts and also help editors decide which manuscripts are proper to publish. Reviewers do not guarantee manuscript quality and scientific misconduct but advise editors on how and under which conditions a manuscript might be improved and on its priority for publication in that journal. In addition to their comments for the authors, reviewers are asked whether the research is sound and coherent, the topic interesting, and the writing of acceptable quality. Where possible, the final decision is made on the basis that peer reviewers are in accordance with one another, or that at least there is no strong dissenting view. In cases, there is strong disagreement, either among the peer review or between the authors and the peer reviewers, advice is sought from an editorial board member or a researcher of similar standing.

Editors are not required to send all manuscripts out for review. They may immediately return or decline some manuscripts to authors without external review, to allow authors to submit the manuscript to another journal without delay.

Editors publish statistics on a regular basis describing their journal’s review process, number of submissions, acceptance rate, average time from submission to the first and final decisions, and article acceptance to final publication (for example see OJAFR archive).

Online Journal of Animal and Feed Research accept submissions via both the Scienceline Online Submission Form and Journal's Online Submission Form. The submitted manuscript must be accompanied by a cover letter in which the authors should state why the manuscript should be considered and evaluated by the OJAFR editorial policies and declare if they have any competing interests. The authors of received manuscripts are also asked to submit a copyright declaration of competing interests as part of their manuscript.

 The main features of the current OJAFR peer-review process are:

  • all decisions are made by editors who are active researchers.
  • we do not artificially limit the number of articles we publish or have a set acceptance rate.
  • editors discuss with reviewers about reviews with "major revision results" before reaching a decision on a manuscript; extra experiments are only requested if they are essential and can be completed within about two months.
  • the decision letter is sent to the author after peer review, and the accepted manuscripts are published if the authors respond.

Our aim is to make peer review faster and fairer, especially for clinical research (by reducing rounds of revision and requesting extra experiments if required).


Firstly, all manuscripts will be checked by one of the plagiarism finding tools (iThenticate, and or ​Turnitin). A double-blind reviewing model is used by OJAFR for non-plagiarized papers. The manuscript is edited by the English language editor and checked by at least 2 reviewers mostly suggested by section editors. Manuscripts that are judged to be of insufficient quality or unlikely to be competitive enough for publication are returned to the authors at the initial stage.

We always try to avoid delays in the reviewing process, but it relies on the time and cooperation of the referees that works without any remuneration, hence, it may take 2 weeks to 2 months. One unfavorable review means that the paper will not be published and possible decisions are: accept as is, minor revision, major revision, or reject.  The corresponding authors should submit back their revisions within 14 days in the case of minor revision, or 30 days in the case of major revision

To submit a revision please click here, fill out the form, and mark "Revised", mention the article code (for example OJAFR-1108), attach the revision (MS word) and continue submission. Manuscripts with significant results are typically reviewed and published at the highest priority. After review and editing the article, a final formatted proof is sent to the corresponding author once again to apply all suggested corrections during the article process. The editor who received the final revisions from the corresponding authors shall not be hold responsible for any mistakes shown in the final publication.
