Author Guidelines

Hasanuddin Journal of Animal Science (HAJAS) is a scientific journal published by the Faculty of Animal Science, Hasanuddin University, twice a year in May and November. HAJAS is a peer-reviewed open-access journal committed to disseminating original research papers and reviews in animal science. Manuscripts that do not follow these guidelines may be returned to the authors before review.

1. Who can submit

HAJAS welcomes manuscripts from academics, researchers, practitioners, postgraduate researchers, and other contributors whose work falls within the Focus and Scope. Submissions are judged on scientific merit, not on nationality, institution, rank, gender, religion, political belief, or other personal characteristics. Authors must have the right to submit the work and must make sure that the submission does not infringe copyright, confidentiality, or other third-party rights.

2. Types of manuscripts

HAJAS accepts original research articles and review articles (see Focus and Scope).

3. Submission requirements

The manuscript must be original and must not have been published in substantially the same form elsewhere. Authors must disclose any closely related earlier version, such as a conference paper, thesis chapter, or preprint.
The manuscript must not be under consideration by another journal. It must not be sent elsewhere until HAJAS has finished its editorial process or has approved a written withdrawal request.
By submitting, the corresponding author confirms that all authors have approved the submission, that authorship is correctly assigned, that sources are acknowledged, and that the required permissions, ethical approvals, and statements are in place.
Authors are responsible for the accuracy, originality, and integrity of everything in their submission.

4. Manuscript file

The manuscript must be written in English (American or British usage is accepted, but not a mixture). It must be spell-checked and grammar-checked.
Provide the article in Microsoft Word format, following the HAJAS manuscript template.
The manuscript should be between 4,000 and 8,000 words, including references and appendices. Allow about 100 to 500 words for each figure or table.
Prepare the manuscript single-spaced, with consecutive page numbers, in Calibri 12 pt.
Embed tables and figures in the text, not in separate files. Cite each table and figure in the text, number it, and give it an explanatory heading.

5. Content of the manuscript

Use the following order of sections.

Article title

Not more than fourteen words, descriptive and concise. Avoid abbreviations and formulae where possible. Capitalize each word of the title where appropriate.

Author details

List the authors in the correct order, with affiliations and email addresses based on where the research was conducted. Mark the corresponding author.

Abstract

In English, a single paragraph of no more than 250 words, covering the introduction, purpose, methods, results, and implications. Do not cite references in the abstract.

Keywords

A maximum of five words or phrases.

Introduction

Give a brief background of the research, its novelty, the state of the art, and the objectives, supported by references. Avoid an extensive literature review.

Materials and Methods

Describe the biological, analytical, and statistical procedures clearly and completely. Cite references for original methods and explain any modification. Describe diets and animal conditions (breed, sex, age, body weight, feeding and watering conditions). Give the name, specification, city, and country of commercial products and equipment. Use appropriate statistical methods and define the models, blocks, and experimental units. Consulting a statistician is recommended.

Results and Discussion

Present data in tables or figures when feasible and avoid duplication. Give measures of variation (for example SD or SE) and significance levels (for example P<0.01). Interpret the results clearly and concisely, support biological mechanisms with literature, relate the findings to the objectives, and do not repeat results already described.

Conclusion

A brief single paragraph that reflects the experimental results and their implications.

Author Contribution

A statement from all authors on who conceived and designed the study, conducted the experiments, analysed the data, and drafted and revised the manuscript, and that all authors have read and approved the final manuscript.

Competing Interest

State any financial or other interests that could be seen to influence the work, or state that the authors have no competing interests.

Funding Statement

List all sources of financial support, sponsorship, or grants for the research and the preparation of the manuscript, with grant numbers where they apply, or state that the research received no specific funding.

Data Availability Statement

State where the data supporting the findings can be accessed, or give the reason why they cannot be shared (see the Data Availability page).

Generative AI Declaration

Place it after the Competing Interest statement and before the Acknowledgment. If generative AI or AI-assisted tools were used, name each tool and version, the purpose, and the sections affected. If none were used, state: "The authors declare that no generative AI or AI-assisted technologies were used in the preparation of this manuscript." (see the Policy on Generative AI).

Ethical Clearance

For research on animals, state the ethics committee that approved the work and the approval number and year. For research involving human participants, state the approving committee, the approval number and year, and that informed consent was obtained. If no approval was required, explain why.

Acknowledgment

Name the individuals or institutions that supported the research but do not qualify as authors.
