  • WC12 tentative program is now available.
  • Your contributions are instrumental in designing an impactful and engaging Congress program.
  • Based on guidelines from the Alternatives Congress Trust to create a well-balanced program reflecting the 3Rs, WC12 Organizing Committee strives to integrate interdisciplinary content for diverse perspectives and learning experience.
  • Abstracts are accepted under 6 Themes and 60 sessions – select the most relevant theme for your content and the best session for its delivery.
  • Organizing Committee reserves the right to reassign speakers under a common theme and propose additional speakers for a given session, as deemed suitable based on abstract submissions and priority themes.
  • ̶A̶b̶s̶t̶r̶a̶c̶t̶s̶ ̶a̶r̶e̶ ̶d̶u̶e̶ ̶o̶n̶ ̶F̶e̶b̶r̶u̶a̶r̶y̶ ̶2̶0̶,̶ ̶2̶0̶2̶3̶.̶  Due to numerous requests, especially from young scientists, we are extending the abstract submission deadline by a few days to Friday, February 24, 2023, 11:59 pm EST Canada/USA.
  • Organizing Committee will review all abstracts submitted through this call for abstracts and work with session promoters to incorporate into designated sessions, as appropriate. Abstract submission does not automatically guarantee acceptance without peer review.
  • Acceptance notifications will be emailed in April 2023.
  • Abstracts selected for the final program must be presented by the designated presenting author, as indicated on the submission.
  • Once accepted, you are expected to register and present the content described in the abstract during the designated Platform or Poster session.
  • Posters will be on display throughout the Congress—enabling attendees to visit the posters at their convenience. Authors will be present during designated periods.
  • All accepted Abstracts will be published (unedited) as an issue of ALTEX Proceedings.

We look forward to your ongoing support and cooperation to help create the most engaging, inspiring, and inclusive multidisciplinary, multisectoral program that we can collectively be proud of—to advance the 3Rs field, for humans and animals.



Select Theme and Session.

Review the tentative program above to determine the best topic for your discoveries. Carefully select the Theme for your proposed abstract (select from six options) and the most appropriate Session for its content (60 options). The Scientific Advisory Committee reserves the right to reassign accepted abstracts to a different Theme or Session in order to accommodate the best fit for your work within the overall scientific program of the conference.

Craft Abstract Title.

The title should be concise yet informative. Use the 3Cs—be creative, concise, and catchy. A short title (50-75 characters) is preferable.

Draft the Abstract Content.

Contributors must provide succinct details for peer-review by an interdisciplinary, multisectoral review committee. There is a limit of 250 words for the abstract (avoid uncommon abbreviations or technical jargon). The purpose of the study should be well defined and clearly stated—describing the subject, highlighting the research, innovation, concepts, and challenges/issues to be addressed under the select theme and format.

We highly recommend a structured abstract, as follows:

  • Clear statement of purpose (incorporating background context and rationale);
  • Very brief statements (2-3 lines) regarding the study design or experimental approach (incorporating critical method identification or hypotheses);
  • Summative or integrated findings or results statements (3-5 lines).
  • A single final highlight statement that incorporates the main take-away message from the findings (conclusion, innovative concept or completed learning objective that addresses the selected themes challenges/issues).

No authours names nor affiliations can be included in the abstract text (this information will be available to the Scientific Advisory Committee from the author identification segment of the abstract portal).



Follow the steps outlined on the Abstract Submission portal accessible through the link below to enter all pertinent information. All abstracts must be submitted electronically. Please do not email abstracts.

Ensure that all authors who contributed to the work are included and that the authors’ names and author order are complete and correct. You must identify a presenting author (option available on submission form). Authors may present and serve as author on multiple abstracts. You may be first author and present in more than one session as long as each submission represents distinct research.

You may cut and paste the body of your abstract from Microsoft Word or a plain text document into the “Abstract Text” area of the form. Proofread your abstract carefully. You will have an opportunity to proofread the complete abstract before submitting the final version.

IMPORTANT DISCLAIMER: Presenters do not receive financial compensation from the World Congress. Each session will be awarded a small allowance, to be allocated to speakers at the chairs' discretion. These funds can only be used for costs directly associated with the Congress (registration, travel, accommodation) and must not be used to provide honoraria for speakers.
