Scope and Policy

Editorial Policies

General policies
Submitted manuscripts must be original and should not be under simultaneous consideration by any other publication or have been previously published in any form or medium. Furthermore, if the article has already undergone any previous evaluation, the corresponding decision letter must be attached during submission, and this fact should be mentioned in the submitted Cover Letter. All authors are entirely responsible for all data, concepts and information contained in the article.

Article processing charges
Animal Reproduction charges a flat fee after the acceptance of the article. There are three different values for the Article Processing Charge (APC), as follows:

  • R$ 1600.00 for non CBRA members
  • R$ 800.00 for CBRA members
  • US$ 450.00  for foreign authors

APC payment of accepted articles must be processed thought the following link:

Waiver and discounts
Authors from low-income countries and without access to grant to cover Article Processing Charges may request a waiver or discount after their manuscript is accepted for publication. Waiver and discounts must be requested through the journal contact page, and should include the accepted manuscript information and author reasons for requesting the waiver or discount.

Open access, copyright and self-archiving policies
All content of the journal and articles published by Animal Reproduction, except where otherwise specified, is licensed under the Creative Commons Attribution License.
Authors of articles published by Animal Reproduction retain copyright of their work licensing under the Creative Commons Attribution License, which allows articles to be re-used and re-distributed without restriction, as long as the original work is correctly cited.
Animal Reproduction encourages Authors to self archive accepted manuscripts by posting them in personal blogs, institutional repositories and scientific social medias, as well as on their personal social medias, as long as the full citation to the journal website version is included.

All manuscripts must be written in Standard American English. We recommend Merriam-Webster’s Dictionary ( for spelling check and the EASE Guidelines for Authors and Translators of Scientific Articles to be Published in English ( Authors whose native language is not English are strongly advised to have their manuscripts checked by a reviewer familiar with scientific language and vocabulary, or by a specialized company, and present a certificate of English editing. Manuscripts not written in acceptable Standard English will be returned to the author before being sent to the scientific reviewers.

Peer Review Process
Animal Reproduction has a 3-stage review process:

  1. All submitted manuscripts undergo a technical verification for compliance with Animal Reproduction policies and manuscript preparation guidelines. Submissions that fail to comply will be un-submitted so that the authors can fix the problems and resubmit them.
  2. Manuscripts are then sent to the Editor-in-chief, who performs a pre-evaluation that includes originality, scope and journal fit. Rejected manuscripts will not be sent to peer-review and will be returned to the authors with the reasons for such editorial decision. The Editors strive to accomplish this first screening stage and send their decision in 70 days.
  3. Manuscripts accepted in this first screening will be sent for a blind evaluation by at least two reviewers. After the ad hoc reviewers finish their evaluation, the handling Editor will return the manuscript to the authors with an accepted, rejected, or for review decision, according to the reviewers’ suggestions. Revised manuscripts submitted by the authors will be sent to the Editor-in-chief for final decision, and reviewers might be asked to perform additional evaluations.
