Aims and Scope
The Journal of Poultry Science (JPS) publishes important original research and invited reviewson all aspects of poultry science. An official publication of the Japan Poultry Science
Association, JPS is an international, peer reviewed, Open Access journal. Articles report on
fundamental and applied research in the areas of breeding and genetics, reproduction, nutrition
and feed, anatomy and histology, general physiology, environment and hygiene, and processing
and products. Articles typically investigate domestic fowl, but the journal welcomes researchon wild birds that addresses fundamental questions in the field of poultry science.
JPS is published quarterly in print and continuously online. The journal is read and used by alarge global audience of researchers, policy makers, and applied practitioners.

Manuscript Types
The journal welcomes three manuscript types, all of which are subject to peer review.
Full Papers
Full Papers present the most common form of articles published in the journal. They describe
novel results of experiments undertaken in order to examine a novel hypothesis. The relevant
background, experimental designs and methods, results and discussion should be cogently
presented and structured.

JPS Instructions to Authors
Research Notes
Research Notes are brief articles describing novel, often unexpected or unexplained
experimental results that deserve immediate publication. The relevant background,experimental designs and methods, results and discussion should be cogently presented andstructured in compact. The length of Research Notes should not exceed 3500 words with 1-2
figures or tables.
Reviews
The contributors of review articles are invited based on the recommendations of the Editorial
Board. Reviews present novel or unique overviews of recent or important developments in thefield and must be insightful and must address the question(s) of interest using appropriate andfully presented evidence. The journal also welcomes proposals from interested authors, whoshould contact the Editor-in-Chief.

Journal & Ethics Policies
The journal supports and adheres to the guidelines and best practices including the
Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in
Medical Journals by the International Committee of Medical Journals Editors (ICMJE), as wellas the Principles of Transparency and Best Practice in Scholarly Publishing(http://doaj.org/bestpractice). For further guidance on ethical practices and procedures
guidelines, refer to the ICMJE Recommendations linked to above.
Before submitting a manuscript to the journal, authors must ensure that they have read andcomplied with the journal’s policies. The journal reserves the right to reject without review, or
retract, any manuscript that the Editor believes may not comply with these policies.
The responsibilities of the journal’s authors, editors, reviewers and publisher regarding researchand publication ethics are described in full below.
Submission to the journal implies that the manuscript has not been previously published (in partor in whole, in any language), is not in press, and is not under consideration for publicationelsewhere.
Authors must inform the editors if any related manuscripts are under consideration, in press or
published elsewhere. The availability of a manuscript on a publicly accessible preprint server
does not constitute prior publication (see ‘Preprints’).
If authors choose to submit their manuscript elsewhere before a final decision has been madeon its suitability for publication in JPS, they should first withdraw it from the journal.
Submission
JPS welcomes manuscript submissions from authors based anywhere in the world.
Submission of a manuscript to the journal implies that all authors: have approved it, warrant it
is factual, have agreed to its submission, and have the rights to publish it.

JPS Instructions to Authors
Originality
Submission to the journal implies that the manuscript is original work. The journal uses
Crossref’s Similarity Check plagiarism software to screen all accepted manuscripts forunoriginal content. By submitting a manuscript to the journal, authors agree to this screening.
Any manuscript with an unacceptable level of unoriginal material may be rejected or retracted
at the Editors’ discretion.
Preprints
To support the wide dissemination of research, the journal encourages authors to post theirresearch manuscripts on community-recognized preprint servers, either before or alongsidesubmission to the journal. This policy applies only to the original version of a manuscript that
describes primary research. Any version of a manuscript that has been revised in response toreviewers’ comments, accepted for publication or published in the journal should not be posted
on a preprint server. Instead, forward links to the published manuscript may be posted on the
preprint server.
Authors should retain copyright in their work when posting to a preprint server.
Scooping
When assessing the novelty of a manuscript submitted to the journal, the editors will not be
influenced by other manuscripts that are posted on community-recognized preprint servers after
the date of submission to JPS (or after the date of posting on a preprint server, if the manuscript
is submitted to the journal within 4 months).
Authorship
Submission to the journal implies that all authors have seen and approved the author list.
Changes to the author list after manuscript submission – such as the insertion or removal of
author names, or a rearrangement of author order – must be approved by all authors and theeditor.
Authors are encouraged to consider the International Committee of Medical Journal Editors(ICMJE) Recommendations on ‘Defining the Role of Authors and Contributors’. The ICMJE
recommends that authorship is based on four criteria: making a substantial contribution to theconception or design of the work, or the acquisition, analysis or interpretation of data for thework; drafting the manuscript or revising it critically for important intellectual content;
approving the final version of the manuscript for publication; and agreeing to be held
accountable for all aspects of the work. Any contributor who has met all four criteria should be
an author on the manuscript. Contributors who do not meet all four criteria should not be authorsof the manuscript but may be included in the Acknowledgements section instead.

JPS Instructions to Authors
Image integrity
Authors may digitally manipulate or process images, but only if the adjustments are kept to aminimum, are applied to the entire image, meet community standards, and are clearly describedin the manuscript. All images in a manuscript must accurately reflect the original data on which
they are based. Authors must not move, remove, add or enhance individual parts of an image.
The editors reserve the right to request original, unprocessed images from the authors. Failure
to provide requested images may result in a manuscript being rejected or retracted.
Reproducing copyrighted material
If a manuscript includes material that is not under the authors’ own copyright, the authors mustobtain permission from the copyright holder(s) to reproduce it.
If a manuscript includes previously published material, the authors must obtain permission fromthe copyright owners and the publisher of the original work to reproduce it. The authors must
cite the original work in their manuscript.
Copies of all reproduction permissions must be included with the manuscript when it is firstsubmitted.
Availability of data and materials
Authors must disclose the source of publicly available data and materials, such as public
repositories or commercial manufacturers, by including accession numbers or company details
in their manuscript, as appropriate.
Authors may make their own data and materials available in Supplementary Material, or bylinking from their manuscript to relevant community-recognized public databases or digital
repositories. All data sets must be made available in full to the editors and reviewers during thepeer review process, and must be made publicly available by the date of publication. Authors
commit to preserving their data sets for at least three years from the date of publication in thejournal.
The journal encourages authors to grant reasonable requests from colleagues to share any data,materials and experimental protocols described in their manuscript.
Animal/human experimentation
Any study or report on human subjects or materials of human origin, must comply with theprovisions of the Declaration of Helsinki and its revisions.
Authors must make it clear that experiments were conducted in a manner that avoided
unnecessary discomfort to the animals through the use of proper management and laboratory
techniques. Experiments shall be conducted in accordance with the principles and specificguidelines presented in Guide for the Care and Use of Agricultural Animals in Japan, or Guide
for the Care and Use of Agricultural Animals in Research and Teaching, 3rd edition, 2010.

JPS Instructions to Authors
Authors must also include in the manuscript text the ethical approval number provided by the
Animal Experiment Committee of affiliated institution. In describing surgical procedures, thetype and dosage of the anesthetic agent must be specified. Intra-abdominal and intrathoracic
invasive surgery requires anesthesia (this includes caponization). The Editor-in-Chief of JPS
may refuse to publish manuscripts that have not complied with these guidelines.
Specimen collection
Manuscripts describing the collection of wildlife specimens or samples should include detailed
information on their provenance and collection methods. Authors must include a statement intheir manuscript describing the relevant ethics guidelines, local laws and collection permits
under which the research was conducted.
Author competing interests and conflicts of interest
In the interests of transparency, the journal requires all authors to declare any competing or
conflicts of interest in relation to their submitted manuscript (in a “Conflicts of Interest” sectionin the manuscript, as described below. A conflict of interest exists when there are actual,
perceived or potential circumstances that could influence an author’s ability to conduct or reportresearch impartially. Potential conflicts include (but are not limited to) competing commercial
or financial interests, commercial affiliations, consulting roles, or ownership of stock or equity.
Confidentiality
The journal maintains the confidentiality of all unpublished manuscripts. By submitting theirmanuscript to the journal, the authors warrant that they will keep all correspondence about theirmanuscript (from the Editorial Office, editors and reviewers) strictly confidential.
Self-archiving (Green Open Access) policy
Self-archiving, also known as Green Open Access, enables authors to deposit a copy of theirmanuscript in an online repository. JPS encourages authors of original research manuscripts to
upload their article to an institutional or public repository immediately after publication in thejournal.
Long-term digital archiving
J-STAGE preserves its full digital library, including JPS, with Portico in a dark archive (seehttps://www.portico.org/publishers/jstage/). In the event that the material becomes unavailable
at J-STAGE, it will be released and made available by Portico.

Advertising Policy
JPS does not accept advertising from any commercial entity, including pharmaceuticalcompanies and device manufacturers.

Peer Review Process
Editorial and peer review process
The journal undertakes single-blind peer review. All submissions to the journal are initiallyreviewed by the Editor-in-Chief and then an appropriate section editor to assess the quality ofthe paper and suitability for the journal. This is based on the originality, validity, andsignificance of the work. Manuscripts can be rejected without full peer review if there isagreement between the responsible section editor and the Editor-in-Chief. Manuscripts judged
as potentially suitable for the journal are sent out for peer review by two experts in the field.
The reviewers’ comments are evaluated by the section editor, who sends a recommendation to
the Editor-in-Chief, who makes the final decision.
The authors of manuscripts that receive “major revision” or “minor revision” decisions should
revise their manuscript according to the reviewers’ and editors’ comments, so as to attend tothe critical intent of the comments. A response letter must be included with the revisedmanuscript, which explains the specific changes in the revised manuscript in a point-by-point
format. Authors should submit the revised manuscript within 6 weeks from the date of thedecision. Unless otherwise arranged, failure to return the manuscript within 6 weeks will beconsidered to be withdrawn from the Journal, however authors who decide not to submit arevision are asked to send a written request for withdrawal to the Editorial Office.
Editor-in-Chief may send the revised manuscript to section editors and reviewers who handled
the manuscript at initial submission to check if the manuscript is appropriately revised assuggested by the reviewers.
Reviewer selection, timing and suggestions
Reviewers are selected without regard to geography and need not belong to the journal’s
Editorial Board. Reviewers are selected based on their expertise in the field, reputation,
recommendation by others, and/or previous experience as peer reviewers for the journal.
Reviewers are invited within 1 weeks of an article being submitted. Reviewers are asked tosubmit their first review within 2 weeks of accepting the invitation to review. Reviewers who
anticipate any delays should inform the Editorial Office as soon as possible.
When submitting a manuscript to the journal, authors are requested to suggest at least 2
reviewers. The Editor may consider these suggestions but is under no obligation to follow them.
The selection, invitation and assignment of peer reviewers is at the Editor’s sole discretion.
Reviewer reports
It is the journal’s policy to transmit reviewers’ comments to the authors in their original form.
However, the journal reserves the right to edit reviewers’ comments, without consulting thereviewers, if they contain offensive language, confidential information or recommendations for
publication.

the published literature, the Editor may recommend acceptance for publication in the journal.
Articles in JPS must be:
•
•
•
•
•
•

within the subject area of the journal’s scope

As the journal owner, the Japan Poultry Science Association (JPSA) has granted the journal’s
Editorial Board complete and sole responsibility for all editorial decisions. The JPSA will not
become involved in editorial decisions, except in cases of a fundamental breakdown of process.
Editorial decisions are based only on a manuscript’s scientific merit and are kept completely
separate from the journal’s other interests. The authors’ ability to pay any publication charges
has no bearing on whether a manuscript is accepted for publication in the journal.
Appeals
Authors who believe that an editorial decision has been made in error may lodge an appeal with
the Editorial Office. Appeals are only considered if the authors provide detailed evidence of amisunderstanding or mistake by a reviewer or editor. Appeals are considered carefully by the
Editor-in-Chief, whose decision is final. The guidelines of the Committee on Publication Ethics(COPE) are followed where and when relevant.
Confidentiality in peer review
The journal maintains the confidentiality of all unpublished manuscripts. Editors will not:• disclose a reviewer’s identity unless the reviewer makes a reasonable request for suchdisclosure• discuss the manuscript or its contents with anyone not directly involved with themanuscript or its peer review• use any data or information from the manuscript in their own work or publications• use information obtained from the peer review process to provide an advantage tothemselves or anyone else, or to disadvantage any individual or organization.

JPS Instructions to Authors
Conflicts of interest in peer review
A conflict of interest exists when there are actual, perceived or potential circumstances that
could influence an editor’s ability to act impartially when assessing a manuscript. Suchcircumstances might include having a personal or professional relationship with an author,
working on the same topic or in direct competition with an author, or having a financial stakein the work or its publication.
Members of the journal’s Editorial Board undertake to declare any conflicts of interest whenhandling manuscripts. An editor who declares a conflict of interest is unassigned from themanuscript in question and is replaced by a new editor.
Corrections, Retractions and Expressions of Concern
JPS publishes corrections, retractions, and expressions of concern as appropriate, and as quickly
as possible.
Corrections
If an error appears in a published article that affects scientific meanings but does not affect theoverall results and conclusions of the paper, a notice of correction will be issued byJPS. Authors
who wish to correct a published article should contact the editor who handled their manuscriptor the Editorial Office with full details of the error(s) and their requested changes. If an error isintroduced by the authors, a correction is published and the author is required to pay all costs
associated with the correction. All corrections will be published in the journal on numberedpages in print and online. The text will explain the changes being made and/or the reasons foraction being taken.
Retractions
If a published paper contains one or more significant errors or inaccuracies that change theoverall results and conclusions of the paper, the entire paper will be retracted. Any individual
who believes that a published article has significant errors is encouraged to contact the journal’s
Editorial Office with full details of their concerns. JPS will assess the information and, if
necessary, request a response from the authors and/or the author’s employers. All retractions
will be published in the journal on numbered pages in print and online. Notices of retraction
will mention the reasons and basis for the retraction.
Editorial Expressions of Concern
When scientific misconduct such as data fabrication, deceptive manipulation of images, orplagiarism is alleged, JPS may publish an Editorial Expression of Concern relating to the paper
in print and online.
The decision to publish Corrections, Retractions or Editorial Expressions of Concern is madeat the sole discretion of the Editor-in-Chief.

JPS Instructions to Authors
Editors as authors in the journal
Any member of the journal’s Editorial Board, including the Editor-in-Chief who is an author
on a submitted manuscript is excluded from the peer review process. Within the journal’s online
manuscript submission and tracking system, they will be able to see their manuscript as an
author but not as an editor, thereby maintaining the confidentiality of peer review.
A manuscript authored by an editor of JPS is subject to the same high standards of peer review
and editorial decision making as any manuscript considered by the journal.
Responding to potential ethical breaches
The journal will respond to allegations of ethical breaches by following its own policies and,
where possible, the guidelines of COPE.
Reviewer Confidentiality
As part of their responsibilities, reviewers agree to maintain the confidentiality of unpublishedmanuscripts at all times. By accepting the invitation to review a manuscript, reviewers agree
not to:• disclose their role in reviewing the manuscript• reveal their identity to any of the authors of the manuscript• discuss the manuscript or its contents with anyone not directly involved in the review
process• involve anyone else in the review (for example, a post-doc or PhD student) without first
requesting permission from the Editor• use any data or information from the manuscript in their own work or publications• use information obtained from the peer review process to provide an advantage tothemselves or anyone else, or to disadvantage any individual or organization.
Reviewer Conflicts of interest
A conflict of interest exists when there are actual, perceived or potential circumstances that
could influence a reviewer’s ability to assess a manuscript impartially. Such circumstancesmight include having a personal or professional relationship with an author, working on thesame topic or in direct competition with an author, having a financial stake in the work or its
publication, or having seen previous versions of the manuscript.
Editors try to avoid conflicts of interest when inviting reviewers, but it is not always possible
to identify potential bias. Reviewers are asked to declare any conflicts of interest to the Editor,
who will determine the best course of action.
