The South African Journal of Animal Science is an open access, peer-reviewed journal. The journal publishes reports of research dealing with the production of farmed animal species (cattle, sheep, goats, pigs, horses, poultry and ostriches), as well as pertinent aspects of research on companion animals and aquatic and wildlife species. All submitted articles are subjected to a single-blind peer review process that is managed by a section 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.
Originally supported by the Agricultural Research Council (ARC), the South African Journal of Animal Science moved online in the early 2000s using a custom-built manuscript submission and editorial management system. In August 2025, the journal transitioned to the Public Knowledge Project’s Open Journal Systems (PKP OJS), hosted by Khulisa Journals at the Academy of Science of South Africa (ASSAf).
In line with international best practices, the journal integrates key components of digital research infrastructure, including DOIs (digital object identifiers), ORCID iDs (researcher identifiers), ROR IDs (research organisation identifiers), and CCLs (Creative Commons Licences), ensuring transparency, traceability, and global interoperability.
As of August 2025, the South African Journal of Animal Science makes use of the Crossref 10.17159 DOI prefix. View the journal metadata health and the Crossref DOI Conflict Report here.

Biological influences on the quality properties of wool
Although only 3,9% of the total world wool production is produced here, South Africa is well known for the high quality of its wool and its classing. In this article quality differences of a biological nature are identified (breeding, feeding…
Biologiese faktore wat die gehalte van sybokhaar beïnvloed
Biological factors that influence the quality of mohair. The influence of the most desirable properties (fineness, length, style, character and lustre) on the price of mohair is discussed briefly. Biological factors such as age, nutrition, genetics, sex, and stress and…
Protein, energy and phosphorus supplementation of cattle fed low-quality forage
The effect of protein, energy and phosphorus supplements, fed individually or in various combinations, on roughage intake and livemass change was measured in a 2 x 2 x 2 factorial arrangement of treatments. The experiment was conducted under controlled conditions…
A laboratory assessment of various treatment conditions affecting the ammoniation of wheat straw by urea. 2. The effect of physi
The effect of physical form, moisture level and prolonged treatment period on the ammoniation of wheat straw using 75 9 urea per kg wheat straw was investigated in a 2 x 3 x 6 factorial experiment. Physical form was represented…
Voluntary feed intake, body composition and efficiency of two Merino crossbreeds
The voluntary feed intake, body composition and efficiency (ME intake/energy retention) of 10 Dorper x Merino and 10 Afrino x Merino lambs were studied. The age of experimental animals ranged from weaning at approximately 120 days, to about 240 days…
Die invloed van dieetproteïen- en energiepeil op die groeiprestasie en veerproduksie van slagvolstruise onder voerkraaltoestande
The effect of diet protein and energy levels on the growth performance and feather production of slaughter ostriches under feedlot conditions. Lucerne , maize and ostrich carcass meal were used to formulate nine diets supplying three protein levels (14,…
Milk progesterone concentrations: an accurate early pregnancy diagnostic aid in dairy cattle
The optimal day of milk sampling for pregnancy diagnosis by milk progesterone quantitation was determined as well as the diagnostic efficiency of the test for days 14 - 24 post insemination in dairy cattle. The results show that on days…
Faktore wat lamvrektes by die Elsenburg Dormer- en SA Vleismerinokuddes beïnvloed
Factors that influence mortality amongst lambs in the Elsenburg Dormer and SA Mutton Merino flocks. Data related to 1 852 SA Mutton Merino and Dormer lambs born in the Elsenburg flocks, during the period 1978 - 1981 inclusive, were analysed…
Supplementary winter feeding and reproduction of beef heifers on Dohne sourveld (Short communication)
Shorthorn and Bonsmara type beef heifers from two breeding seasons were allocated to a high (H), medium (M) and low (L) level of nutrition after weaning at 7 months of age. The feeding levels were applied for 145 days (1972…
Influence of pen area and trough space on feedlot performance of beef cattle (Short communication)
Two experiments were conducted to measure the influence of trough space (170 mm, 350 mm and 700 mm/animal) and pen area (5,5 m2, 11 m2 and 22 m2/animal) on feedlot performance. There was no advantage in allowing more than 170…
Sodium and steam-treated sugarcane bagasse in low and high fibre fattening diets for lambs (Short communication)
The purpose of this trial was to evaluate two methods of roughage treatment and two levels of treated roughage in complete rations for weaner lambs. A 3 x 2 factorial arrangement of treatments was used. Untreated, sodium hydroxide-treated, and steam-treated…
Die invloed van speenouderdom op die doeltreffenheid van ’n versnelde paringsfrekwensie met skape (Kort mededeling)
The influence of weaning age on the efficiency of an accelerated mating frequency with sheep. One hundred late pregnant South African Mutton Merino ewes were divided into two comparable groups (an early and a late-weaning group) of 50 animals each…
