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

Investigating novelty traits to improve cow-calf efficiency in South African Afrikaner, Angus and Charolais for climate-smart production
The aim is of the study was to identify novelty traits that could be used as breeding objectives to improve cow-calf efficiency and describe cow efficiency in extensive systems in support of climate-smart production in beef cattle. The traits that…
Effects of exogenous fibrolytic enzymes on the ruminal fermentation of agro-industrial by-products
This research was performed to evaluate the effects of increasing doses of exogenous fibrolytic enzymes (EFE), namely at 0 (control), 1 (low), 2 (medium) and 4 (high) μL/g dry matter (DM), on the ruminal fermentation of low-quality agro-industrial by-products, grape…
Aluminosilicates and yeast-based mycotoxin binders: Their ameliorated effects on growth, immunity and serum chemistry in broilers fed aflatoxin and ochratoxin
The aim of this study was to evaluate the effects of commercial toxin binders on growth performance, organ morphology, immunity and serum biochemistry in broilers. Dietary treatments consisted of the negative control (NC): experimental diet with aflatoxin B1 <20 parts…
Genetic diversity and population structure of Turkish native cattle breeds
Cattle are an important livestock species for human life, but certain breeds are at risk of extinction. Maintaining genetic diversity plays an important role in sustainable breeding and conservation programmes in farm animals. The aim of this study was to…
Antioxidant activity and duodenum transporter gene expression in quail fed citric acid
The study aimed to evaluate the effects of citric acid supplementation on the performance and the gene expression in the duodenum of Japanese quail. Genes related to antioxidant activity: superoxide dismutase (SOD) and glutathione peroxidase 7 (GPX7); and genes related…
Effect of additives on fermentation characteristics, nutrient values and in vitro fermentation profile of Neolamarckia cadamba leaf silage
This study was designed to investigate the effects of additives on the ensiling characteristics of Neolamarckia cadamba leaf (NCL) silage. The NCL were allocated to six ensiling treatments, namely control (C-S), uncompacted (UC-S) (negative control), with the addition of sodium…
Effects of exogenous tannase enzyme on growth performance, antioxidant status, immune response, gut morphology and intestinal microflora of chicks fed grape pomace
An experiment was conducted to study the effects of dietary addition of tannase to feed of chicks including grape pomace (GP) on growth performance, antioxidant status, immune response, blood parameters, gut morphology, intestinal microflora, liver function, and histopathological responses. The…
Meat quality of weaner steers adapted to a diet containing potassium humate in the feedlot
The objective of the study was to determine the meat quality responses of weaner steers fed diets containing potassium humate (PH) in a feedlot. Twenty-two yearling male steers were randomly allocated to two treatments: control (n = 11), fed a…
Relationship of ewe reproduction with subjectively assessed wool and conformation traits in the Elsenburg Merino flock
Subjectively assessed wool and conformation traits are widely used to select breeding ewes and rams in the sheep industry. Data from a Merino flock that is maintained at Elsenburg Research Farm were used to investigate animal model (co)variance components for…
Effects of inulin, carrot and cellulose fibres on the properties of raw and fried chicken meatballs
The effects of inulin, carrot, and cellulose fibres (3%, 6%, and 9%) on raw and fried chicken meatballs were studied. Meatball pH, thiobarbituric acid reactive substances (TBARS), and colour values were determined for raw samples in refrigerated storage on the…
Comparison of greenhouse gas emissions from Mexican intensive dairy farms
The objectives of this study were to compare estimates of greenhouse gas emissions (GHG) as CH4 (enteric-manure), N2O (manure), and CO2 (fuel and energy use), the use of water and soil, the excretion of nutrients in manure, and feed efficiency…
Altered tissue mineralization, increased hepatic lipid and inhibited autophagy in intrauterine growth retardation piglets
Mineral homeostasis is often disrupted in intrauterine growth retardation (IUGR) infants. Most studies focus on calcium or phosphorus metabolism of IUGR infants via determining serum mineral concentrations instead of tissues. This study was conducted to investigate the effects of IUGR…
Effects of supplemental seminal plasma on cryopreserved boar sperm quality (Short communication)
To analyse the effects of supplemental autologous seminal plasma on boar semen quality before freezing and after thawing, thirty ejaculates were collected from six Pietrain boars. The main factors of a 2 x 2 x 2 factorial arrangement of treatments…
Effects of short and extended fasting periods and cattle breed on glycogenolysis, sarcomere shortening and Warner-Bratzler shear force
The effects of short (three hours) and extended (24 hours) feed withdrawal periods and three cattle breeds on muscle energy metabolism, sarcomere length, and meat quality were investigated. Brahman (Br), Nguni (Ng), and Simmental (Sm) bulls were subjected to ante-mortem…
