Manuscripts should be submitted via the online platform and must include:

  • An electronic version of the main text (MS Word format) that includes tables (preferably in MS Word format), charts (Excel format), figures and photographs (TIFF at a 300 dpi size, they must also be uploaded individually) in it; supplementary material must be added separately.
  • A cover letter to the Editor signed by the corresponding author must include the following:
  1. An explanation of why your manuscript should be published in AJVS, including a general overview about the novelty and contribution to the field of the data presented.
  2. An explanation of any issues relating to Journal Policies. A declaration of any potential Competing interests (Please refer to Editorial Policies for further details).
  3. Confirmation that all authors have read and approved the final version of the manuscript for submission (The statement must include the email address of all the authors).
  4. Confirmation that the content of the manuscript has not been published, or submitted for publication elsewhere.

  6. If you are submitting a manuscript to a particular special issue, please refer to its specific name in your covering letter.
  7. List of 3 potential reviewers.
  8. Mention any researchers who should NOT review your manuscript.
  • Manuscripts should fulfill the editorial requirements in order to continue the review process.



Referees of AJVS will aid the Editorial Committee to determine whether the manuscript fulfills publication requirements. All articles submitted for publication will be assessed by two independent referees. The referees will be selected by the Editorial Committee, and may (but not necessarily) include those suggested by the author. In case of a disagreement between the referee’s reports, a third referee will aid the Editorial Committee to reach a decision. Referees are obliged to keep all information from the articles confidential, including unpublished information. Authors should state any potential conflicts of interest at the time of submission of the manuscript. Such information will not alter established editorial and review policies but will assist the editorial staff in avoiding any potential conflicts that could give the appearance of a biased review. The final decision regarding acceptance of the manuscript will be taken when the Editorial Committee accepts the manuscript following correction according to the referees’ comments and their own. Accepted articles must pay a publication fee prior to publication via Web-Pay. 



General presentation: Manuscripts must be written using 12 point Times New Roman font with one and a half-line spacing, on one side only of letter paper (21.5 x 27.9 cm) using 2 cm margins on all sides. Pages must be numbered consecutively in the top right corner, and lines must be numbered on the left, continuously. Headings must be in upper case, left-justified on a separate line with no full stop following, e.g. MATERIAL AND METHODS. Only the first letter of sub-headings is capitalised. Primary sub-headings (e.g. Experimental design) should be left-justified; secondary sub-headings are left-justified and italicised. Do not use underlining and do not number sub-headings or itemised lists. In the text, numbers must be written in numerals. When a sentence begins with a number or when necessary for clarity, this should be written in words. A decimal point must be preceded by a number (e.g. 0.5 not .5). All measurements must be reported in SI units ( unless it is normal practice in a discipline to use derivatives (e.g. the Curie international unit). Dates must be formatted as 07 September, 2021 in the text, but they may be abbreviated in tables and figures. Use the 24-hour clock for times of day (e. g. 13:00 h). Chemical nomenclature must be expressed using the Biochemical Society Standards (Biochem J 209, 1-27, 1983), generic names (in lower caps) must be used for medications. If brands and sources of medications need to be included, this should be included as a foot-note. Enzymes must be identified at first mention, in accordance with the Enzyme Commission of the International Union of Biochemistry. Latin terminology and abbreviations commonly used in scientific literature, such as in vitroin vivoad libitum must be italicised. Scientific names of animal species should be mentioned once in the text, complete and in brackets, subsequently only the common or abbreviated (when possible) name should be used. Probability values must be presented as P<0.05 or P<0.01. Standard deviation, standard error of the mean and confidence intervals are abbreviated as follows: SD, SEM and CI, respectively.

Title: Title must be short, specific and informative. The title is centred in bold without using trade names or abbreviations. Only the first letter is capitalised. Scientific names of animal species must be mentioned in the title, in brackets, only in the case of non-domestic species.

Author’s names and addresses: Author’s names are written underneath the title, separated by a space. Use full name and separate authors by commas, as in the example: Christopher A. Westwood, Edward G. Bramley, Ian J. Lean. Superscript letters should be used after each author’s name to identify affiliation as follows:  Laboratory, Institute, Department, Organization, City, and Country.  The corresponding author is indicated using the superscript letter followed by an asterisk, with email addresses indicated in the footnote.

Footnotes: These are used to indicate a web page address (URL) and to define abbreviations used in table titles, commercial brands, the name and address of companies. They must be indicated with numbers.

Abstract: The second page must contain an abstract of no more than 300 words that render the general significance and conceptual advance of the work clearly accessible to a broad readership. The abstract should describe the objectives of the study or research,  the material and methods used, the principal results, and the most important conclusions. Non-standard abbreviations must not be used. 

Key words: All article types require a minimum of 5 and a maximum of 8 keywords. They should be indicated below the Abstract. The use of key words containing more than two words (a phrase) and/or words contained in the title should be avoided.

Introduction: The subheading “Introduction” is written on the next page following the Abstract. In the following line, the context of the study is briefly presented with no subheadings. The hypothesis and objectives of the study must be clearly and concisely presented. 

Material and Methods: This section may be divided by subheadings and should contain sufficient detail so that when read in conjunction with cited references, allow others to repeat the procedures. When the first reference in the text is made to medications or chemicals, the generic name, dose and route of administration should be indicated. For specialised equipment, the brand, model and manufacturer’s name must be indicated. Studies involving animals or humans must mention the appropriate Bioethical Committee Certification.

Results: This section may be divided by subheadings and should contain a concise and logical description of the results obtained without discussion or reference to other work. The results can be supported by tables and/or figures that present the pertinent data. Data presented in tables and figures should not be repeated in the text. In the case of Original research articles only, this section and the Discussion are separated.

Discussion: This section may be divided by subheadings and should cover the key findings of the study, evaluate and interpret the results and relate these to other relevant results. The results should not be repeated, and new results must not be presented in this section. Care should be taken to ensure that the discussion is developed in a logical and concise manner, discussing the potential shortcomings and limitations on their interpretations. Conclusions that are not directly supported by the data of the study or other unpublished studies should not be presented.

Review article

Reviews provide expert summaries of current knowledge in a particular field of veterinary science and do not necessarily have a set format. Articles should provide comprehensive depth and a balanced perspective, avoiding merely summarize the literature. A review should focus on fundamental concepts or issues, current research gaps, potential development of the field, controversies. The Editorial Committee asks for an expert to prepare a review on specific topics, which will also be refereed and edited. Articles are peer-reviewed and must not exceed 15,000 words in length and may contain no more than 4 figures/tables.

Make a new submission to the Review article section.

Original article

Letters to the Editor

A letter judged suitable for publication will be printed in a “Letters to the Editor” section of AJVS. The purpose of this section is to provide a forum for scientific exchange relating to articles published in AJVS. To be acceptable for publication, a letter must adhere to the following guidelines.

  • Only a letter that addresses matters of science and relates to information published in AJVS during the last year will be considered. In general, a letter should not exceed 500 words and should contain no more than 5 citations.
  • A letter should provide supporting evidence based on published data for the points made or must develop logical scientific hypotheses. A letter based on conjecture or unsubstantiated claims will not be published. No new data may be presented in a letter.
  • The Editorial Committee will evaluate each letter and determine whether a letter is appropriate for publication. If a letter is considered appropriate, the author(s) of original AJVS article(s) will be invited to write a letter of response. Normally both letters will be published together.
  • All letters will be subject to acceptance and editing by the Editorial committee and editing by a technical editor.
