Ovozoa: Journal of Animal Reproduction is a journal that contains scientific articles on animal reproduction and animal reproductive biotechnology published by the Department of Veterinary Reproduction of Airlangga University together with the Association of the Indonesian Veterinary Reproduction Department (ADERVI) three times per year on April, August, and December. Ovozoa: Journal of Animal Reproduction received manuscripts in the form of original research articles, review articles, and case reports in Indonesian and English. Manuscripts received must be original, current, and have never been published or are being planned to be published in other scientific journals.

Manuscripts must be submitted online through the Open Journal System (OJS) in Word format.The entire text is typed in Times New Roman 12pt double spaced, using line numbers. The title is written with a Sentence case capitalisation (bold, 14pt, centered). The full length of the manuscripts is a maximum of 15 pages of A4 paper with a top margin of 2.2 cm, other margins of 2 cm, and consecutive page numbers. Italicise only for species names or terms that have not been standardised as Indonesian. Define abbreviations upon first appearance in the text. Do not use non-standard abbreviations unless they appear at least three times in the text. Keep abbreviations to a minimum. Avoid unnecessary duplication of text.


The first page contains full names of all  authors without titles and initials (bold, centered), followed by the name and complete address of the respective institution(marked with numeric superscripts) and e-mail of corresponding authors (marked with *superscript), and must include the ORCID id of at least one of the authors, approval of ethical commission, and acknowledgements if applicable.

The second page forward containstype of article (ORIGINAL ARTICLE, REVIEW ARTICLE, or CASE REPORT), title, abstract and keywords in English and Indonesian, followed by introduction, materials and methods, results, discussion, conclusions, and references.

Title should be concise but informative, as far as possible, in no more than 12 words.

Abstract written English, do not exceed 250 words, containing elements of background, material and methods, results, and conclusions.

Keywords maximum of 6 (six) words or phrases, written after the abstract in each language, alphabetically ordered. As far as possible, avoid using keywords from the title.

Introduction should be brief, containing elements of background, problems, objectives, and reference sources that support.

Research materials (materials and equipment) do not need to be mentioned separately, but rather integrated into the method used, complete with the brand and catalog number if applicable. Do not include common supplies, such as test tubes, pipette tips, beakers, etc. or standard laboratory equipment. The name and address of the laboratories need not be mentioned.

Method must be concise but sufficiently detailed (with reference or modification), so other researcherscan repeatresearch.

Results are displayed in a concise but clear narrative with/without tables or figures.

Tables are made without vertical lines (use only lines at the top and bottom of the table as well as for separating heading from the main table), with table title placed before the table, numbered in Arabic numerals (Table X), and have to bereferred in the text.

Image (in JPEG format) is sent in a separate file. The title and description of the figureare placed after the References.

Discussion contains the explanation of what is found related to the importance of your study and how it may be able to answer the research question, comparison of results (internally, between research data, and externally, compared with findings from other studies), and cause-effect analysis.

Conclusion does not only repeat the results of the study, but summarise the findings into a narrative that impacts on the development of science and or practitioners in the field of veterinary reproduction.

Approval of Ethical Commission has to be stated (number and institution) if the manuscript is constructed based on research using live animals.
