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.

Effects of varying levels of thermostable xylanase, amylase and protease (TXAP) enzyme supplement on body growth of broiler chic
AbstractA dose-response experiment was conducted with Ross broiler chickens from day-old to 42d of age to determine the effect of exogenous composite enzyme (TXAP) on broiler performance and the most beneficial rate of inclusion. Broiler chickens were fed maize-soyabean…
Genetic analysis of somatic cell score and udder type traits in South African Holstein cows
Selection accuracy for resistance to mastitis may be increased by combining somatic cell score (SCS) and udder type into an udder health index, using genetic parameter estimates among them. A multi-trait animal model was used to estimate genetic parameters among…
Effect of dietary conjugated linoleic acid (CLA) on the growth and lipid metabolism of geese and fatty acid composition of their
The objective of this study was to determine the effects of conjugated linoleic acid (CLA) oil supplementation on the growth performance and lipid metabolism in geese and the fatty acid concentrations in their liver and muscle tissues. One hundred and…
Effects of dietary probiotic and prebiotic supplementation on growth performance and serum IgG concentration of broilers
This study was conducted to investigate the effects of probiotic and/or prebiotic supplementation on growth performance and serum IgG concentrations in broilers. One thousand two hundred one-day old Ross-308 broiler chicks of mixed sex were randomly divided into four treatment…
Determination of metabolisable energy of five cultivars of hulless barley using adult Leghorn cockerels (Short communication)
Hulless barley contains more digestible nutrients than do whole barleys due to a lower content of indigestible fibre, but also contains a higher concentration of ß-glucans. The chemical composition and apparent metabolisable energy (AME) of five cultivars (3, 7, 12,…
Across flock genetic parameter estimation for yearling body weight and fleece traits in the South African Dohne Merino populatio
Accurate genetic parameter estimates are needed upon which to perform multiple-trait across flock breed analyses. Genetic parameters for yearling body weight (BW), clean fleece weight (CFW) and mean fibre diameter (MFD) were estimated using records of 107 389 individuals (the…
Shelled acorn seed (Quercus cerris) as a diet ingredient on the performance of growing Japanese Quail (Short communication)
This study was carried out to investigate the effects of dietary inclusion of shelled acorn seed (Quercus cerris) on the growth performance and carcass yield of Japanese quail (Coturnix coturnix japonica). Four hundred four-day old quail chicks were used in…
The effect of plant age on the chemical composition of fresh and ensiled Agave salmiana leaves
In the first study dry matter (DM), organic matter, crude protein (CP), neutral detergent fibre (NDF) and soluble carbohydrate (SC) concentrations were determined in whole leaves and the upper and lower sections of whole leaves of the Agave salmiana (Otto…
The use of a cluster analysis in across herd genetic evaluation for beef cattle
To investigate the possibility of a genotype x environment interaction in Bonsmara cattle, a cluster analysis was performed on weaning weight records of 72 811 Bonsmara calves, the progeny of 1 434 sires and 24 186 dams in 35 herds…
Effect of short-term pre-hatch heat shock of incubating eggs on subsequent broiler performance
The aim of this study was to investigate the effect of thermal conditioning of broiler chickens during embryonic development on subsequent performance under standard rearing conditions. During incubation eggs from 32-, 45- and 56-week old Ross 308 broiler parent stock…
Live weight and reproduction performance of Zimbabwean Blue and South African Black ostriches
Data obtained from a pair-mated ostrich flock located at Oudtshoorn in South Africa were used to derive line differences for live weight and reproduction performance in sexually mature ostriches of the Zimbabwean Blue (ZB) and South African Black (SAB) strains…
Threonine and lysine requirements for maintenance in chickens
In order to describe the response of broiler breeder hens to dietary amino acids and to develop an effective model for the precise feeding of these birds after sexual maturity, accurate estimates of the amounts of each amino acid required…
Sprout selection and performance of goats fed Acacia karroo coppices in the False Thornveld of the Eastern Cape, South Africa
Acacia karroo Hayne is the dominant invading species in semi-arid savannas of South Africa and is an ecological threat of our modern era. This study investigated the preference and intake rates by goats when fed A. karroo coppice sprouts of…
Effects of dietary oil sources on egg quality, fatty acid composition of eggs and blood lipids in laying quail

Cloning and SNP screening of the TLR4 gene and the association between its polymorphism and somatic cell score in dairy cattle
Toll-like receptor 4 (TLR4) is a cell-surface receptor that activates innate and adaptive immune responses. Recognizing a broad class of pathogen-associated molecular patterns (PAMPs), TLR4 is implicated as a receptor mediating cellular activation in response to bacterial lipopolysaccharide (LPS), a…
