Scope and policy

The “Revista de la Facultad de Medicina Veterinaria y de Zootecnia” publishes case reports as well as original, review, and opinion articles in all areas of veterinary medicine and animal science. Submissions accepted for evaluation will be sent to a minimum of two peer reviewers. In case of lack of consensus among the reviewers, the editor or editorial committee decides whether the contribution is accepted or not. When articles are accepted for publication the authors should revise them according to the peer’s observations within the timeframe given. Observations not taken into consideration shall be appropriately supported and will be evaluated by the corresponding editor. The editor and editorial committee reserve the right to accept or reject the contributions submitted.

Form and preparation of manuscripts

For article submission to the editorial committee of the journal it is necessary to comply with the following requirements:

1. Contributions must be original and must not have been submitted to any other journal (except when they have been published as theses or as abstracts in a congress).

2. The authors transfer all publication rights to the journal, in both printed and electronic versions. Electronic versions include all databases where the journal has been indexed.

3. The article publication must have been approved by all coauthors and by the authorities where the research took place.

4. The submission must comply with all requirements described in the present document which can also be downloaded from the journal web site: Submissions that do not comply with these requirements will be returned to the authors without consideration for evaluation.


The journal accepts the following types of original contributions:

Scientific article: original scientific paper reporting the results of a research conducted under the scientific method. It typically contains four essential parts: Introduction, materials and methods, results and discussion (either individually or combined) and conclusions.

Case report: report of clinical cases that become relevant and publishable due to their specific context.

Review articles: critical review of a specific topic. This type of contribution is recommended only for authors with proved research experience in the topic. It should present not only a critical review of the state of the art of the topic but also a proposal of new areas to be investigated.

Opinion article: critical thoughts about a specific scientific topic.

The article text must be submitted in MS-Word®, without tables or figures, which shall be sent in separate files. It is recommended that the text is not longer than 25 pages, letter size, numbered consecutively at the bottom right corner with margins of 2.5 cm on each side. Lines shall be numbered consecutively. Use Times New Roman 12 pt font.

Tables and figures shall be number consecutively in the text using Arabic numbers and shall be sent inserted in MS-Word® files as well as in its original format (e.g. jpg o MS-Excel®). All tables and figures must be mentioned in the text.

Title and authors
The article title must be written in English and Spanish, in bold, and centered. If scientific names are used, they must be written using the binomial system. The name of the authors must be written under the title as follows: given name initials (with periods) follow by the last name with no academic titles. Each author is separated of the next one by a comma. The corresponding author will be identified with an asterisk. Each author’s affiliation shall be shown as a footer including address, city and country as well as the electronic address of the corresponding author.

Summary and key words
Articles shall include a summary in English and another in Spanish which must contain up to 250 words. The summary shall include a brief description of all parts of the article including the objectives, materials and methods, results and discussion, and conclusions. The most important findings of the study should be highlighted in the abstract.

Key words (up to four) are terms for indexation of the article on databases and Internet search engines. They shall identify the article contents and. Key words shall be placed after the summary in each language. To select the key words it is recommended to consult the descriptors of the agricultural thesaurus AGROVOC of the FAO ( and DeCS ( and These tools help select appropriate key words so that the article is more visible on the Internet.

This section shall present a brief review of previous studies related to the topic of research and shall finish with a brief justification of the study and its objectives. The introduction shall not include data or conclusions of the study being described.

Materials and methods
This section must describe in clear, concise and logical form both the materials (animals, laboratory equipment, etc.) used as well as the detailed description of the techniques or protocols followed. This information given shall allow another research to be able to perform the same experiment(s) in detail. This section shall also describe the statistical treatment of the data and shall not include results or discussion of the results.

This section shall describe the results in a logical order and in an objective and sequential fashion with the help of tables and figures. This section might include subheadings and shall not discuss the data presented.

This section shall be a synthesis of the comparison of the observed data against published relevant literature with an interpretation of the similarities and differences found. It will focus on the interpretation of the experimental findings and shall not repeat information presented in the introduction or the results sections. In some cases it is possible to combine the results and discussion sections in one.

This section describes the most relevant findings of the research conducted, that is, those that make a significant contribution to the advancement of the specific topic investigated. It shall also point out towards future research needed.

When necessary, acknowledgements can be given in this section to people or institutions that helped with the satisfactory development of the study being reported.

  • Each table shall have a short but explicative title on top (without abbreviations and with a period at the end).
  • No vertical lines shall be included in the tables.
  • Any additional explanation to the table shall be presented as a note at the bottom
  • Column titles shall be short but explicative.
  • Each table must be referenced in the text.

  • Photographs or maps (either originals or scanned) must be sent as individual files, in tiff or jpg format and a minimum of 600 dpi of resolution. Additionally these graphs must be sent embedded in a MS Word® file with the title of the figure at the bottom.
  • Figures shall be numbered with Arabic numbers, consecutively and each one must be referenced in the text.


  • Units must be expressed in the International System of Units (SI).
  • Authors must follow the International Code of Botanical Nomenclature, the International Code of Nomenclature of Bacteria, and the International Code of Zoological Nomenclature.

For referring publications in the text, the Council of Science Editors (CSE) style must be used: “author(s) year” system shall be used for one or two authors (Jiménez 2009), (Pineda y Rodríguez 2010); if the publication has three or more authors the last name of the first author is cited with the latin expression et al. in italic: (Bernard et al. 2003). When more than one reference is cited they shall be organized in alphabetical order, separated by a semicolon (;): (Hänsel and Gretel 1990; Hergé et al. 1983). When the author is cited within the sentence the same notation shall be used but with the year in brackets: Wagner (1982) found out that water wets but Vivaldi and Pergolessi (1988) do not agree; the researchers Magendie et al. (1845) discovered that dogs have four legs. The complete references shall be included at the end of the article according to the format described below. When two or more references of the author are cited they shall be listed in chronological order starting with the oldest one.

Contributions that do not comply with the references’ requirements will be returned to the authors without consideration for publication.

• Italic font must be used for Latin names (binomial system) and words or expression written in a different language.

• The meaning of abbreviations must be explained in full the first time they are used. Afterwards use only the abbreviation.

• Abbreviations do not have a plural form: one NGO, two ELISA.

• SI abbreviations shall not have a period at the end or be written in plural or upper case letters: 1 kg, 25 g, 10 cm, 30 m, etc. The abbreviations must commonly used in this journal are:

km       kilometer
m         meter
cm       centimeter
mm      millimeter
µm       micrometer
nm       nanometer
kg        kilogram
g         gram
mg       milligram
µg       microgram
ng       nanogram
l          liter
ml        milliliter
µl        microliter
m        mol
M        molar
mM      millimolar
µM       micromolar
N         normal
ppm     parts per million (1 x 10-6)
ppb      parts per billion (1 x 10-9)
cpm     counts per minute
dpm     disintegrations per minute
s          seconds
min      minutes
h          hour
sc        subcutaneous
im        intramuscular
ip         intraperitoneal
iv         intravenous
po        oral

• Always insert a space between the numeric value and the symbol: 35 g (not 35g), p > 12 (not p>12); except for the signs %, +, - (these last two when meaning positive and negative). For example: 99%, +45, -37.

• In a series of measurements the symbol goes at the end. For example: 3, 6 and 9 m (except for the percentage sign which is always written: 14%, 16% and 18%).

• The slash bar (/) is a linguistic sign used sometimes instead of the word per: ten chicks /pen, 4 tablet/d, 10 fruits/branch. This symbol can be used in a non linguistic context to express quotients of measurement and unit magnitudes: 80 km/h, 10 ml/min, 10°C/h.

• The sign period can be used in a non linguistic context to indicate multiplication. In this case it is used separated and in the middle: 6 · 3 = 18; 2 · (x + y) = 30.

• En English language the period (.) is used to separate decimals and the comma (,) to separate thousands.

• Name-based units must be written in lower case (for example: one siemens), except when they are derived from a proper name: °C, degrees Celsius.

Ethical considerations

Authorship. Only a person who has made a significant and substantial contribution to the manuscript shall be included as author. This contribution shall include his/her participation in tasks such as the conception of the experiment and the experimental design, raw data collection, data reduction analysis and interpretation of results, application of the appropriate statistical model, elaboration of the manuscript and bibliographical search. Every author shall be able to explain his direct involvement with the manuscript and be able to defend its contents if the Editorial Committee so requires. Including honorary authors (improper author contribution) is considered unethical and unacceptable.

Manuscript submission. Documents submitted for evaluation and possible publication must not be submitted to other journal(s) simultaneously. This voids its originality and compromises the publication rights.

Manuscript integrity. Fabrication or making up results through instrument, materials or research processes manipulation, changing or omitting results or data, plagiarism (citation of his/her own or other's results without clarification according to citation rules), fragmented submission (submission of fragments as independent articles, also known as "salami science") are all considered unethical practices and are unacceptable.

Conflict of interests. Authors need to declare that they do not have any commercial or personal interest with the research that resulted in the production of the submitted manuscript.

Acknowledgements. Any type of support received, including financial resources, scholarships, and equipment, shall be mentioned and acknowledged. 

Manuscript evaluation. Reviewers will only accept to review manuscripts that are within their area of expertise. Their opinions shall be objective and based only on academic and scientific grounds, without any personal consideration. During the evaluation process the reviewer must keep the contents of the manuscript confidential and shall not assign the reviewing task to any other person (co-researcher, graduate student, etc.). If during the reviewing process the referee finds any conflict of interest or any ethical conflict, he/she shall stop the evaluation process and let the Editorial Committee know about this.
