The South African Journal of Animal Science is an open access journal. The journal publishes reports of research dealing with production of farmed animal species (cattle, sheep, goats, pigs, horses, poultry and ostriches), as well as pertinent aspects of research on aquatic and wildlife species. All submitted articles are subjected to a single-blind peer review process that is managed by a sub-editor under the supervision of the editor-in-chief. Copyright of a published article resides with the authors. Such articles will be published as open access content and be covered by the terms of the Creative Commons Attribution 4.0 South African Licence. Users may copy, distribute, transmit and adapt the work, but must recognise the authors and the South African Journal of Animal Science.

The South African Journal of Animal Science makes use of an Online Journal Management System  that was developed in collaboration with the Agricultural Research Council to facilitate the manuscript submission and review process. Authors are kindly requested to submit all articles for publication in the South African Journal of Animal Science via the Online Journal Management system.
