Scope and policy

Revista Mexicana de Ciencias Pecuarias is a scientific journal published in a bilingual format (Spanish and English) which carries three types of articles: Research Articles, Technical Notes, and Reviews. Authors interested in publishing in this journal, should follow the below-mentioned directives which are based on those set down by the International Committee of Medical Journal Editors (ICMJE) Bol. Of. Sanit. Panam. 1989; 107:422-437.


Form and preparation of manuscripts

1. Only original unpublished works will be accepted. Manuscripts based on routine tests, will not be accepted. All experimental data must be subjected to statistical analysis.

2. All contributions will be peer reviewed by a scientific editorial committee. The Editor-in-Chief will notify the author the date of manuscript receipt.

3. A single copy of the manuscript should be submitted, typed in a 12 points font at double space (including the abstract and tables), together with a WordPerfect or MSWord file on disk containing the article for publication. At the time of submission a signed agreement co-author letter should be mailed or faxed (+52 999/941.50.30); co-authors at different institutions can mail or fax this form independently. The corresponding author should be indicated together with his address (a post office box will not be accepted), telephone, fax, and E-mail. Also, papers can be submitted by E-mail (

4. To facilitate peer review all pages should be numbered consecutively, including tables, illustrations and graphics, and the lines of each page should be numbered as well.

5. Manuscripts of all three type of articles published in Revista Mexicana de Ciencias Pecuarias should contain the following sections, and each one should begin on a separate page.

Title page
Tables and Graphics

6. Title page. This section should include: a) Title, which should be concise but informative; b) Each author's name, accompanied by their institutional affiliation; c) Departments and institutions to whom the work should be attributed; d) Declarations of discharge of responsibilities, if necessary; e) Name and address of the author responsible for correspondence related to the manuscript; and f) Origin of funding.

7. Abstract. On the second page a summary of no more than 250 words should be included. This abstract should start with a clear statement of the objectives and must include basic procedures and methodology. The more significant results and their statistical value and the main conclusions should be elaborated briefly. At the end of the abstract, and on a separate line, a list of up to 10 key words or short phrases that best describe the nature of the research should be stated.

8. Text. The three categories of articles which are published in Revista Mexicana de Ciencias Pecuarias are the following:

a) Research Articles. They should originate in primary works and may show partial or final results of research. The text of the article must include the following parts:

Materials and Methods
Results Discussion
Conclusions and implications

In lengthy articles, it may be necessary to add other sections to make the content clearer. Results and Discussion can be shown as a single section if considered appropriate.

b) Technical Notes. They should be brief and be evidence for technical changes, reports of clinical cases of special interest, complete description of a limited investigation, or research results which should be published as a note in the opinion of the editors. The text will contain the same information presented in the sections of the research article but without section titles.

c) Reviews. The purpose of these papers is to summarize, analyze and discuss an outstanding topic. The text of these articles should include the following sections: Introduction, as many sections as needed that relate to the description of the topic in question, and Discussion.

9. Acknowledgements. Whenever appropriate, collaborations that need recognition should be specified: a) Acknowledgement of technical support; b) Financial and material support, specifying its nature; and c) Financial relationships that could be the source of a conflict of interest. People which collaborated in the article may be named, adding their function or contribution; for example: "scientific advisor, critical review", data collection, etc.

10. References. All references should be quoted in their original language. They should be numbered consecutively in the order in which they are first mentioned in the text. Text, tables and figure references should be identified by means of Arabic numbers. Avoid, whenever possible, mentioning in the text the name of the authors. Abstain from using abstracts as references. Also, “unpublished observations” and personal communications should not be used as references, although they can be inserted in the text (inside brackets).

Key rules for references

a. The names of the authors should be quoted beginning with the last name spelt with initial capitals, followed by the initials of the first and middle name(s). In the presence of compound last names, add a dash between both, i.e. Elías-Calles E. Do not use any punctuation sign, nor separation between the initials of an author; separate each author with a comma, even after the last but one.

b. The title of the paper should be written in full, followed by the abbreviated title of the journal without any punctuation sign; then the year of the publication, after that the number of the volume, followed by the number (in brackets) of the journal and finally the number of pages (this in the event of ordinary article).

c. Accepted articles, even if still not published, can be included in the list of references, as long as the journal is specified and followed by in press (in brackets).

d. In the case of a single author's book (or more than one, but all responsible for the book's contents), the title of the book should be indicated after the names(s), the number of the edition, the country, the printing house and the year.

e. When a reference is made of a chapter of book written by several authors; the name of the author(s) of the chapter should be quoted, followed by the title of the chapter, the editors and the title of the book, the country, the printing house, the year, and the initial and final pages.

f. In the case of a thesis, references should be made of the author's name, the title of the research, the degree obtained, followed by the name of the City, State, and Country, the University (not the school), and finally the year.


The style of the following examples, which are partly based on the format the National Library of Medicine of the United States employs in its Index Medicus, should be taken as a model.
