"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

Effect of varying levels of dietary inclusion of sweet lupin on the growth production characteristics of ostriches (Struthio camelus var. domesticus)

  • 2019
  • Issue: 2
  • Volume: 49
T.S. Brand, J.A. Engelbrecht, J. van der Merwe & L.C. Hoffman Page: 345 - 362

Nutrition contributes approximately 75% of the total input costs to an intensive ostrich production unit. An increase in the price of traditional protein sources thus necessitates finding cheaper alternatives. Sweet lupins were identified as a possible alternative; therefore, the effect…
