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.

Optimization of response to selection using genomic selection in indigenous chicken breeding programmes

  • 2021
  • Issue: 6
  • Volume: 51
C.W. Ndung’u, T.K. Muasya, & T.O. Okeno Page: 723 - 734

This study tested the hypothesis that the use of pooled genetic and phenotypic parameters and genomic selection would optimize selection response in indigenous chicken breeding programmes. This premise was tested with deterministic simulation in three breeding schemes based on the…

Gene-set enrichment analysis of selective sweeps reveals phenotypic traits in Nguni cattle

  • 2021
  • Issue: 6
  • Volume: 51
A.A. Zwane, K.S. Nxumalo, M.L. Makgahlela, E. Van Marle-Koster & N. Maiwashe Page: 761 - 777

Adaptation of animals to different environments is typically associated with structural and functional genomic variations. High throughput SNP genotyping and next-generation sequencing (NGS) have made it possible to study positive selection footprints and adaptation traits. Nguni is a small frame-size…
