"Experientia docet" - Experience is the best teacher

The South African Society for Animal Science (SASAS) has changed the way the journal submission process is handled. An Online Journal Management System  had been developed in collaboration with the Agricultural Research Council (ARC) to facilitate the Journal Submission & Review Process.

Authors are kindly requested to submit all future articles for publication in the SA Journal of Animal Science via the Online Journal Management system.

If you experience any problems with the system, please contact the Editor at sajas.eic@gmail.com.
