Instructions for authors


Wayamba Journal of Animal Science (WJAS) is an open-access peer-reviewed journal published by the Society of Animal Science, Wayamba University of Sri Lanka. The WJAS provides a forum for the rapid dissemination of significant novel and high impact research in all disciplines of Animal Production.  The journal will cover the fields of Animal Production, Nutrition, Physiology, Genetics & Breeding, Animal Products, Animal Behaviour, etc. Articles typically report research with dairy and beef cattle, goats, sheep, pigs, poultry (chicken, turkey, duck, goose, guinea fowl, pigeon, etc.), and companion animals; however, studies involving other farm animals and laboratory animal species that address fundamental questions related to livestock will also be considered.


Academics, scientists, industrialists, technologists, policymakers and other relative stakeholders engaged in animal production


The journal publishes novel and original research articles, invited reviews, letters to the editor and other scholarly work encompassing a broad range of research topics in animal production.

Types of Papers

Research papers – original full-length research articles which have not been published previously except in a preliminary form, and which should not exceed 7000 words excluding the abstract and references (with no more than 8 tables, figures and illustrations in combination)

Review articles – will be accepted in areas of topical research covered by the scope of the journal. Comprehensive and definitive reviews will only be considered. Reviews must contain a critical assessment of literature including authors’ views on the subject. They should not exceed 10,000 words (excluding abstract, references, and no more than 8 tables and illustrations in combination)

Short communications – up to 3,000 words from Introduction to Conclusion (excluding Abstract and References). These papers should describe work that may be preliminary but merits publication, and should not contain more than 40 references.


Ethics in publishing

The WJAS fully adheres to the Code of Conduct ( and Best Practice Guidelines ( of the Committee on Publication Ethics (COPE). The journal adopts a rigorous peer-review process along with strict ethical policies to ensure a quality scholarly publication.  Authors who wish to publish their papers in WJAS should adhere to the following:

  • All authors must disclose any conflict of interest in the paper before the submission.
  • Authors should accurately present their research findings along with a sufficient discussion on the significance of their findings.
  • Methods used in the study must be adequately described in a way that another researcher can replicate the work. 
  • Authors should have their data readily available for the presentation to the referees and the Editors of the journal whenever requested. Authors should retain experimental data for a reasonable period even after publication.
  • Simultaneous submission of the same manuscript to more than one journal should be strictly avoided.
  • Plagiarism, data fabrication and manipulation are zero tolerated. Copying text, ideas, images, and/or data from other sources, even from your own publications, without giving any credit to the original source should be avoided. Copied text from another source must be between quotes and the original source should be cited. If plagiarism is detected during the peer review process, the manuscript will be rejected. If irregular image manipulation (e.g., amending features of the original image) is identified and confirmed during the peer review process, the manuscript will be rejected.

Studies using Humans and Animals

Research work involving human subjects should be carried out in accordance with the Declaration of Helsinki ( Accordingly, approval from an ethics review committee should be obtained before undertaking the research. The ethical statement: “The study was approved by the Ethics Committee of XXX (Project identification code) and was conducted in accordance with the Declaration of Helsinki. Written consent was obtained from all subjects before they participated in the study.” Should be included in the manuscript.

Ethical guidelines for the use of animals

Experiments involving animals should comply with the ARRIVE Guidelines ( and should be conducted in accordance with the U.K. Animals (Scientific Procedures) Act, 1986 and associated guidelines, EU Directive 2010/63/EU for animal experiments, or the National Research Council’s Guide for the Care and Use of Laboratory Animals. Accordingly, approval from an ethics review committee should be obtained before undertaking the research.

Editors reserve the right to reject any submitted article that does not comply with these requirements.

Use of Inclusive Language

The WJAS encourage its authors to produce articles using inclusive language by avoiding expressions that are considered to express or imply ideas that are sexiest, otherwise biased, prejudiced or denigrating to any particular group (please refer). Authors should ensure that the manuscript is free from bias, stereotypes, slang, and reference to the dominant culture and/or cultural assumptions. Authors are recommended to maintain gender neutrality by using plural terms (e.g., doctors, scientists, researchers, etc.) wherever possible to avoid using “he” or  “she”.


Manuscripts for the WJAS should be submitted online at The corresponding author is responsible for the manuscript during the submission and peer-review process. The submitting author must ensure that all eligible co-authors have been included in the author list. All the typeset documents should be submitted in editable format (e.g., Microsoft Word). When preparing manuscripts, Microsoft-word template file must be used. All correspondence, including the Editor’s decision and instructions for any revisions, is communicated by e-mail.

Suggesting Reviewers

Authors can suggest names and institutional e-mail addresses of a maximum of three potential referees review the manuscript. The referees should not be from the same institution where the work was carried out or should not have been co-authors in previous publications. Editors do not invite reviewers who have potential competing interests with the authors. However, the Editor decides whether or not to invite referees suggested by the authors.

Authorship contributions

Please note that those who have substantially contributed to the concept or design of the work, the acquisition, analysis or interpretation of the results, drafted or critically revised the work for important intellectual content, approved the final version to be published and agreed to be accountable for all aspects of the work are eligible for the authorship. Authors should be named based on their individual contributions to the manuscript using the relevant CRediT Roles: Conceptualization; Data curation; Formal analysis; funding acquisition; Investigation; Methodology; Project administration; Resources: Software; Supervision; Validation; Visualization; Writing-original draft; and Writing – review and editing (please refer to for more information). The authorship statement should be incorporated above the acknowledgement section. Authorship statements should be formatted with the names of authors first followed by CRediT Roles.

Changes to authorship

Any addition, deletion or rearrangement of author names must be made only before the manuscript has been accepted. However, any alteration to the original list of authorship can only be made if approved by the journal editor upon producing a written confirmation (e-mail or letter) from all authors that they agree with the proposed alternation.

Supplementary Materials

Upon a request made by the reviewers and/or Editor-in-chief, the authors are requested to provide any experimental data or any other supplementary material necessary to evaluate the claims made in the paper but not have included in the paper.

Peer Review

The WJAS adapts a double-blind review process. The manuscripts submitted to the WJAS will initially be screened by the editorial and if suitable, will be sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. When revision of a manuscript has been requested, the revised manuscript should be submitted on or before the stated deadline. The authors’ response to the reviver’s comments should be given in the tabulated form (comments, responses and line numbers should be given). All the alterations made to the original text must be in blue-coloured font for easy recognition. If the revised manuscript was not received within the stated time, the manuscript will not be processed further. Based on The Editor-in-chief is responsible for the final decision regarding the acceptance or rejection of articles. 

Article publication fees
