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.

Relationship of glycogen and lactate concentrations as a pork quality indicator
Muscle metabolites greatly determine pork quality. However, precise threshold values which indicate its deterioration or improvement are not fully known. This study aimed to determine the influences of pork Longissimus lumborum (LL) glycogen and lactate concentrations measured at 45 min…
Pistacia terebinthus as a dietary supplement for laying hens
The aim of this study was to explore the potential of Pistacia terebinthus (terebinth) seed meal as a dietary supplement for laying hens. One hundred and ninety-two Babcock 30-week-old laying hens were assigned to one of six treatments (n =…
Effects of polyunsaturated fatty acids in diets fed to sows on fatty acids in brain, muscle and skin of their piglets
The aim of this research was to determine fatty acid profiles in piglet brain, skin, and muscle, and in the milk of sows fed fat with different saturation grades during gestation and lactation. At 42 days of gestation, 50 multiparous…
Carcass, physicochemical and sensory characteristics of meat from genetic reserve ducks after two reproductive seasons
The aim of the study was to compare carcass composition and meat quality of i) Pekin ducks of French origin (P9), ii) crosses of wild mallard and Pekin duck (K2), and iii) crosses of Khaki Campbell drakes and Orpington Fauve…
Potential alternative feed sources for ruminant feeding from the biodiesel production chain by-products
This study aimed to evaluate the chemical composition, fractionation of nitrogen compounds and carbohydrates, digestibility parameters, gas production kinetics and ruminal fermentation of fruit seed cakes. The experiment was conducted in a completely randomized design with three fruit seed cakes…
Naringin supplementation affects performance, carcass traits, meat quality and oxidative stability of finishing pigs
Naringin is a major flavanone derivate that has many important biological functions in animals. However, its effect on pigs is unknown. The aim of this study was to investigate the effect of naringin supplementation on performance, carcass traits, meat quality…
Effects of soil type on density of trees and nutritive value of tree leaves in selected communal areas of South Africa
This study aimed to describe the distribution and nutritive value of woody species growing in clay-loamy and red-brown sand from selected localities of North West, South Africa. Three 2.2 km transects, radiating from homesteads, which served as replicates, were established…
Performance trait analysis and genetic diversity of the SA Boerperd
This study determined the occurrence and frequency of mutations that influence performance traits in the SA Boerperd horse and evaluated genetic diversity within the breed. Two gait-associated and two height-associated mutations were investigated. Seventeen microsatellite markers were genotyped for 363…
Effect of zinc nanoparticles on embryo and chicken growth, and the content of zinc in tissues and faeces
The hypothesis was that owing to their high bioavailability, zinc oxide nanoparticles (NanoZnO) can effectively replace (Zn) salts and reduce Zn excretion with faeces. The objective of this study was to investigate the effects of NanoZnO on the development of…
Correlations between PORCUS classification and androstenone in boars, and effects of cooking methods thereon
The aim of this research was to evaluate relationships between the PORCUS classification system and factors affecting boar taint in pork. Intact male pork carcasses (n = 176) were randomly selected in a South African commercial abattoir from three PORCUS…
Effect of different levels of supplementation after weaning on beef heifer development
The purpose of the study was to identify a cost-effective supplementation regimen to rear replacement heifers on transitional Cymbopogon-Themeda veld. A total of 120 Drakensberger heifers aged 6 - 7 months were randomly allocated to three supplementary treatment groups from…
Photoperiod effects on carcass traits, meat quality, and stress response in heart and lung of broilers
This study evaluated effects of photoperiod treatments on slaughter and carcass traits, meat quality, indicators of oxidative stress, and heat shock protein 70 (Hsp70) levels of lung and heart tissues in broilers. Five hundred Ross 308 broiler chicks were used.…
Effect of breed on meat quality and global acceptance of native lambs and their crosses
International projections point to the growth in global production of sheep meat, mainly from developing countries. However, the exigencies of consumers on characterization of production systems, nutritional information, and sensorial analysis to target the preferences must be answered. The aim…
Chemical, nutritive, fermentation profile and gas production of citrus pulp silages, alone or combined with maize silage
Quality attributes of citrus pulp silages that were ensiled alone and combined with maize silage were determined. Fresh samples of lemon, orange and tangerine pulps, maize plants and their combinations were fermented in glass jars for 90 days at about…
Cumulative incidence and causal risk factors of carcass condemnations in a South African high-throughput cattle abattoir
Carcass condemnation is a problem in the South African beef industry, but the causes and risk factors have not been studied or quantified. Better understanding of the cumulative incidence and causative predictors of carcass condemnations could assist in improving cattle…
Variation in quality of newly hatched chicks from Japanese breeder quail fed guava extract
The aim of this study was to evaluate the effects of guava extract as a dietary supplement for Japanese quail hens on incubation parameters, intestinal development, and the quality of newly hatched chicks. Six hundred and forty-eight eggs were collected…
Impact of dried brewers’ grains supplementation on performance, metabolism and meat quality of broiler chickens
The objective was to evaluate increasing levels of dried brewers’ grains (DBG) in feed for broiler chickens from 1 to 21 days old and their effect on performance, blood parameters, intestinal morphometry, carcass characteristics and meat quality. The design was…
Fatty acid profile and oxidative stability of egg yolks from hens under different production systems
This study was carried out to compare the egg quality, fatty acid (FA) profiles, and oxidative stability of yolks from hens maintained in cages and fed a conventional diet (CON), those fed a conventional diet with free access to outdoor…
Manipulating the onset of lambing season in communal ewes through hormonal intervention
The study was conducted to evaluate the effectiveness of using long-acting medroxyprogesterone acetate (MPA) to delay the lambing season in communal wool sheep ewes. The study was conducted in three phases. In phase 1, a random assessment was made to…
