Guidelines and Policies

The Editorial Policies and Guidelines outlined here must be followed. If you have any questions, please contact us prior to your submission.

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

This journal does not have submission charges. Animal Reproduction charges only 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$ 650,00  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

This is an open access journal which means that all content is freely available without charge to the user or his/her institution. Users are allowed to read, download, copy, distribute, print, search, or link to the full texts of the articles, or use them for any other lawful purpose, without asking prior permission from the publisher or the author. This is in accordance with the BOAI (Budapest Open Access Initiative) definition of open access. Accepted articles will be published as Open Access and distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

Authors of articles published by Animal Reproduction retain copyright of their work without restrictions, licensing it 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 single 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.

Section Policies

Animal Reproduction does not impose a limit on the number of words and references for Original and Review articles, but editors and reviewers might make recommendations regarding text clarity and quality and excess or lack or relevance of references.

Original Articles

Articles reporting original research studies and/or data related to the subject fields covered by Animal Reproduction.

Original Articles are open for author submission and must not have been previously published elsewhere.

Review Articles

Review Articles of interest to the field of animal reproduction will be submitted by direct invitation of the editorial board, but authors might also submit review manuscripts.

Short Communications 

Short Communications must report or be related to new techniques involved in the biology of reproduction.

They are open for author submissions and must have a maximum of 2000 words, including the list of references, and only two panel figures and two tables.

Data sharing policies

Animal Reproduction is developing its data sharing policies with the TOP (Transparency and Openness Promotion) Guidelines in mind.

As of July 2019, Animal Reproduction is encouraging authors to deposit their research data into the relevant data repository and include a citation and link to the dataset in the submitted articles. If this is not possible, authors should make a statement in the Cover Letter explaining why research data cannot be shared.

Corrections and retractions policy

Animal Reproduction fully endorses the ICMJE recommendations regarding scientific misconduct and is committed to publishing corrections when problems are detected in published information that affect the publication record and/or its scientific accuracy. Editors will follow the ICMJE recommendations and the procedures detailed by the Committee on Publication Ethics (COPE) when suspected misconduct arises, before or after publication. CBRA Scientific Affairs and Publications Directors might be called to assist with the investigation but final decision to publish corrections, expressions of concern, or retracting published articles will be made by the Editor-in-Chief.

Authors, Reviewers and Editors are encouraged to report any suspected research ethics or publication malpractice issue using the journals contact page or by directly writing to the CBRA Publications or Scientific Affairs directors.
