The Sociedade Brasileira de Zootecnia (SBZ), founded on 26 July 1951, in Piracicaba, São Paulo, is a nonprofit association.
The Society, which gathers professionals related to the Animal Science area, has been meeting since 1972. The Annual Meeting of the SBZ is a scientific event, in which the most recent advances in the area of Animal Science are presented.
Revista Brasileira de Zootecnia is a publication of Sociedade Brasileira de Zootecnia, aimed at disseminating original unpublished research papers, that cover the broad area of Animal Science such as Animal production systems and agribusiness, Forage, Nutrition, Genetics and breeding, Reproduction, Aquaculture, Biometeorology, and Animal welfare.
In 1972, it was published the first issue of Revista da Sociedade Brasileira de Zootecnia. In 1997, the journal was resized and its title was changed to Revista Brasileira de Zootecnia (ISSN 1516-3598). From 1973 to 1978, two issues were published per year; from 1979 to 1984, four issues per year; and from 1985 to 2007, the journal was published bimonthly. In 2008, the Revista Brasileira de Zootecnia started a monthly publication. In 2018, the Revista Brasileira de Zootecnia adopted the rolling pass volume system.
Over the years, Revista Brasileira de Zootecnia has undergone changes, such as increase in the number of published issues, change in layout and dimensions of publications, printed and on-line editions, open access to articles, and an increase in the number of articles published in English. Following the trend of many journals, in 2010, Revista Brasileira de Zootecnia started to be published only in electronic format (ISSN 1806-9290).
Its abbreviated title is R. Bras. Zootec., that should be utilized in bibliographies, footnotes, references and bibliographic strips.

Scope and Editorial policies
The Revista Brasileira de Zootecnia (RBZ; Brazilian Journal of Animal Science) encompasses all fields of Animal Science Research. The RBZ publishes original scientific articles in the areas of Aquaculture, Biometeorology and Animal Welfare, Forage Crops and Grasslands, Animal and Forage Plants Breeding and Genetics, Animal Reproduction, Ruminant and Non-Ruminant Nutrition, and Animal Production Systems and Agribusiness.
Open access and peer review
The RBZ is sponsored by the Brazilian Society of Animal Science, which provides readers or their institutions with open access to peer-reviewed articles published online by RBZ. Users have the right to read, download, copy, distribute, print, search, or link to the full texts of articles. Revista Brasileira de Zootecnia is included in the Directory of Open Access Journals (DOAJ).
All the contents of this journal, except where otherwise noted, are licensed under a Creative Commons attribution-type BY, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
A peer-review system is exerted on manuscripts sent for appreciation to maintain standards of quality, improve performance, and provide credibility. We use the double-blind style of reviewing by concealing the identity of the authors from the reviewers, and vice versa. Communication with authors should only be through the Scientific Editor (named as Editor-in-chief). Authors are given the chance to designate names to be considered by the Editor-in-chief as opposed reviewers. Reviewers should notify the editor about conflicts of interest (either positive or negative) that may compromise their ability to provide a fair and an unbiased review.
Assurance of contents form
When submitting a manuscript for review, authors should make sure that the results of the work are original, and that the total or partial content of the manuscript, regardless of the language, has not been/ is not being considered for publication in any other scientific journal. Additionally, the authors assure that if they have used the work and/or words of others this has been appropriately cited or quoted warranting absence of plagiarism, which constitutes unethical publishing behavior.
Papers already published or that have been submitted to any other journal will not be accepted. Fractioned or subdivided studies should be submitted together because they will be assigned to the same reviewers.
The content of the articles published by Revista Brasileira de Zootecnia is of sole responsibility of their authors.
After completing the submission of the manuscript by using the Manuscript Central™ online system, the corresponding author will be asked to e-mail the file named Assurance of contents form and will be responsible for stating the information required in the document regarding the manuscript and all co-authors. A template with the same name has been already prepared by the Brazilian Society of Animal Science and is available on the journal website at https://www.rbz.org.br/assurance.
The original text of the template must not be altered but only completed with the necessary information. The corresponding author must fill it out properly, sign it, initial all pages, scan and email it to RBZ’s office e-mail address firstname.lastname@example.org confirming all authors’ participation in the manuscript.
The manuscript will not be considered for peer reviewing without this form. The deadline will be set allowing a period of 15 days for delivery of forms after which the editorial office will act by withdrawing the manuscript.
Submissions will only be accepted in the English language (either American or British spelling). The editorial board of RBZ reserves the right to demand that authors revise the translation or to cancel the processing of the manuscript if the English version submitted contains errors of spelling, punctuation, grammar, terminology, jargons or semantics that can either compromise good understanding or not follow the Journal's standards. It is strongly recommended that the translation process be performed by a professional experienced in scientific writing familiar with Animal Science, preferably a native speaker of English.
The current article publication fee in the journal is of R$ 215.00 (Two hundred and fifteen reals and no cents) per page if at least one author is a member of the SBZ. The member must be the first author or the corresponding author of the manuscript. If no authors are SBZ members, the publication fee is of R$ 323.00 (Three hundred and twenty-three reals and no cents) per journal page. The Real is the present-day currency of Brazil. Its sign is R$.
Care and use of animals
Revista Brasileira de Zootecnia is committed to the highest ethical standards of animal care and use. Research presented in manuscripts reporting the use of animals must guarantee to have been conducted in accordance with applicable federal, state, and local laws, regulations, and policies governing the care and use of animals. The author should ensure that the manuscript contains a statement that all procedures were performed in compliance with relevant laws and institutional guidelines and, whenever pertinent, that the appropriate institutional committee(s) has approved them before commencement of the study.
Types of articles
Full-length research article: A full-length research paper provides a complete account of the experimental work. The text should represent the research process and foster its cohesive understanding and a coherent explanation regarding all the experimental procedures and results and must provide the minimal information necessary for an independent reproduction of the research.
Short communication: A succinct account of the final results of an experimental work, which has full justification for publication, although with a volume of information which is not sufficient to be considered a full-length research article. The results used as the basis to prepare the short communication cannot be used subsequently, neither partially nor wholly, for the presentation of a full-length article.
Technical note: An evaluation report or proposition of a method, procedure or technique that correlates with the scope of RBZ. Whenever possible, one should show the advantages and disadvantages of the new method, procedure or technique proposed, as well as its comparison with those previously or currently employed, presenting the proper scientific rigor in analysis, comparison, and discussion of results.
Board-invited reviews: An approach that represents state-of-the-art or critical view of issues of interest and relevance to the scientific community. It can only be submitted by invitation of the editorial board of RBZ. The invited reviews will be subjected to the peer-review process.
Editorial: Notes to clarify and establish technical guidelines and/or philosophy for designing and making of articles to be submitted and evaluated by RBZ. The editorials will be drafted by or at the invitation of the editorial board of RBZ.
Guidelines to prepare the manuscript
Structure of a full-length research article
Figures, Tables, and Acknowledgments should be sent as separated files and not as part of the body of the manuscript.
The article is divided into sections with numbered headings, in bold and aligned to the left, in the following order: 1. Introduction, 2. Material and Methods, 3. Results, 4. Discussion, and 5. Conclusions. The sections Acknowledgments (optional) and References should not be numered. The Material and Methods, Results, and Discussion sections can contain subsections, which will be defined by authors if they find it convenient for helping readability making it clear, accurate, and concise.
The text should be typed by using Cambria font at 12 points, double-space (except for Abstract and Tables, which should be set at 1.5 space), and top, bottom, left, and right margins of 2.5, 2.5, 3.5, and 2.5 cm, respectively, with numered lines. The file must be edited by using Microsoft Word® software
The title should be precise and informative, with no more than 20 words. It should be typed in bold and centered as the example: Nutritional value of sugar cane for ruminants. Names of sponsor of grants for the research should always be presented in the Acknowledgments section.
The name and institutions of authors will be requested at the submission process; therefore they should not be presented in the body of the manuscript. Please see the topic Guidelines to submit the manuscript for details.
The list of authors must contain all authors’ full name with no initials, current e-mail address, and complete information about their affiliation. This list must follow the same authorship order presented in the Assurance of Contents form.
Spurious and "ghost" authorships constitute an unethical behavior. Collaborative inputs, hand labor, and other types of work that do not imply intellectual contribution may be mentioned in the Acknowledgments section.
All authors must have their ORCID linked to the ScholarOne system account at the time of manuscript submission.
Revista Brasileira de Zootecnia, for the sake of clarity, transparency, and to give authors the credit they deserve, is now including an Author Contributions section in all primary research paper issued. We endorse the Project CRediT taxonomy of contributor roles which is available at https://casrai.org/credit/.
The RBZ editorial office will require that the corresponding author disclose the statement at the time of manuscript submission describing the roles exerted by each contributor as follows:
The abstract should contain no more than 1,800 characters including spaces in a single paragraph. The information in the abstract must be precise. Extensive abstracts will be returned to be adequate with the guidelines.
The abstract should summarize the objective, material and methods, results and conclusions. It should not contain any introduction. References are never cited in the abstract.
The text should be justified and typed at 1.5 space and come at the beginning of the manuscript with the word ABSTRACT capitalized, and initiated at 1.0 cm from the left margin. To avoid redundancy the presentation of significance levels of probability is not allowed in this section.
A t the end of the abstract, list a minimum of three and no more than six keywords (which must not be in the tittle), set off by commas and presented in alphabetical order. They should be elaborated so that the article is quickly found in bibliographical research. The keywords should be justified and typed in lowercase. There must be no period mark after keywords
The introduction should not exceed 2,500 characters with spaces, briefly summarizing the context of the subject, the justifications for the research and its objectives; otherwise it will be rerouted for adaptation. Discussion based on references to support a specific concept should be avoided in the introduction.
Inferences on results obtained should be presented in the Discussion section.
Material and Methods
Whenever applicable, describe at the beginning of the section that the work was conducted in accordance with ethical standards and approved by the Ethics and Biosafety Committee of the institution. Provide the ethics committee numbe r as follows: “Research on animals was conducted according to the institutional committee on animal use (case number).”
As for the location of the experiment, it should contain city, state, country, and geographical coordinates (latitude, longitude, elevation). Names of universities, laboratories, farms or any other intitutions must not be mentioned.
A clear description on the specific original reference is required for biological, analytical and statistical procedures. Any modifications in those procedures must be explained in detail.
The presentation of the statistical model as a separate sentence and a numbered equation is mandatory whenever the research is about designed experiments, observational studies, or survey studies. All terms, assumptions, and fitting procedures must be fully described to allow readers for a correct identification of the experimental unit and how the model was fitted.
We strongly recommend the use of Greek lowercase letters for fixed effects and Latin lowercase letters for variables and random effects for the sake of notation standardization.
Mathematical formulas and equations must be inserted in the text as an object and by using Microsoft Equation or a similar tool.
All mathematical formulas, including the statistical model(s), must be numbered
The author must write two sections by separating results and discussion. In the Results section, sufficient data, with means and some measure of uncertainty (standard error, coefficient of variation, confidence intervals, etc.) are mandatory, to provide the reader with the power to interpret the results of the experiment and make his own judgment. The additional guidelines for styles and units of RBZ should be checked for the correct understanding of the exposure of results in tables. The Results section cannot contain references.
In the Discussion section, the author should discuss the results clearly and concisely and integrate the findings with the literature published to provide the reader with a broad base on which they will accept or reject the author's hypothesis.
Loose paragraphs and references presenting weak relationship with the problem being discussed must be avoided. Neither speculative ideas nor propositions about the hypothesis or hypotheses under study are encouraged.
Be absolutely certain that this section highlights what is new and the strongest and most important inferences that can be drawn from your observations. Include the broader implications of your results. The conclusions are stated by using the present tense.
Do not present results in the conclusions, except when they are strictly important for the generalization.
This section is optional and must not be included in the body of the manuscript; instead, a separate file named Acknowledgments should be uploaded as “supplemental file NOT for review”. This procedure helps RBZ to conceal the identity of authors from the reviewers.
Use of abbreviations and acronyms
Author-created abbreviations and acronyms should be defined at first use in the abstract, again in the body of the manuscript, and in each table and figure in which they are used.
These type of author-created abbreviations and acronyms should be avoided: “The dry matter intake in T3 was higher than in T4”. This type of writing is appropriate for the author, but of complex understanding by the readers, and characterizes a verbose and imprecise writing.
Tables and Figures
It is essential that tables be built by option “Insert Table” in distinct cells, on Microsoft Word® menu. No tables with values separated by the ENTER key or pasted as figure will be accepted. Tables and figures prepared by other means will be rerouted to author for adequacy to the journal guidelines.
Tables and figures should be numbered sequentially in Arabic numerals, presented in two separate editable files to be uploaded (one for the tables and one for the figures), and must not appear in the body of the manuscript. They may be uploaded separately and in a higher number of files if the size of the files hampers the upload.
The title of the tables and figures should be short and informative, and the descriptions of the variables in the body of the table should be avoided.
In the graphs, designations of the variables on the X and Y axes should have their initials in capital letters and the units in parentheses.
Non-original figures, i.e., figures published elsewhere, are only allowed to be published in RBZ with the express written consent of the publisher or copyright owner. It should contain, after the title, the source from where they were extracted, which must be cited.
The units and font (Cambria) in the body of the figures and tables should be standardized.
The curves must be identified in the figure itself. Excessive information that compromises the understanding of the graph should be avoided.
Use contrasting markers such as circles, crosses, squares, triangles or diamonds (full or empty) to represent points of curves in the graph.
Figures should be built by using Microsoft Excel® to allow corrections during copy-editing, and uploaded as a separate editable Microsoft Word® file, named “Figures” during submission. Use lines with at least 3/4 width. Figures should be sent without any 3-D or shade effects and bold effect.
The decimal numbers presented within the tables and figures must contain a point, not a comma mark.
Reference and citations should follow the Name and Year System (Author-date).
Citations in the text
The author's citations in the text are in lowercase, followed by year of publication. In the case of two authors, use ‘and'; in the case of three or more authors, cite only the surname of the first author, followed by the abbreviation et al.
The references should be arranged chronologically and then alphabetically within a year, using a semicolon (;) to separate multiple citations within parentheses, e.g.: (Carvalho, 1985; Britto, 1998; Carvalho et al., 2001).
Two or more publications by the same author or group of authors in the same year shall be differentiated by adding lowercase letters after the date, e.g., (Silva, 2004a,b).
Personal communication can only be used if strictly necessary for the development or understanding of the study. Therefore, it is not part of the reference list, so it is placed only as a footnote. The author's last name and first and middle initials, followed by the phrase "personal communication", the date of notification, name, state and country of the institution to which the author is bound.
References should be written in alphabetical order of surname of author(s), and then chronologically.
All authors' names must appear in the References section.
Each author is indicated by their last name followed by initials. Initials should be followed by period (.) and a space; the authors should be separated by semicolons, except for the last author that is preceded by the word ‘and’.
e.g.: Casaccia, J. L.; Pires, C. C. and Restle, J
Surnames with indications of relatedness (Filho, Jr., Neto, Sobrinho, etc.) should be spelled out after the last name (e.g., Silva Sobrinho, J.).
As in text citations, multiple citations of same author or group of authors in the same year shall be differentiated by adding lowercase letters after the date.
In the case of homonyms of cities, add the name of the state and country (e.g., Gainesville, FL, EUA; Gainesville, VA, EUA).
Sample references are given below.
The journal name should be written in full. Articles should be cited along with their DOI.
In order to standardize this type of reference, it is not necessary to quote the website, only volume, page range, year and DOI. Do not use a comma (,) to separate journal title from its volume; separate periodical volume from page numbers with a colon (:)
