"Experientia docet" - Experience is the best teacher

The South African Society for Animal Science (SASAS) has recently undertaken the task of changing the way the journal submission process is handled. In collaboration with the Agricultural Research Council (ARC) it has developed an Online Journal Management System 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 jvryssen@up.ac.za
