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

Pre-weaning growth performance and carcass traits of Awassi and Chios-Awassi lambs
One hundred and three lambs (26 Chios-Awassi (CA) and 77 Awassi (AA)) were used to evaluate the effect of crossbreeding on growth performance, body dimensions and carcass characteristics. At weaning, 8 CA and 8 AA male lambs were randomly selected…
Pineapple stem by-product as a feed source for growth performance, ruminal fermentation, carcass and meat quality of Holstein steers
This experiment was conducted to determine the effects of pineapple stem by-product silage as a feed source in total replacement of Napier or corn silages on growth performance, feed intake and feed efficiency, ruminal fermentation, carcass characteristics and meat quality…
Effects of dietary total sulphur amino acids to lysine ratio on performance, nitrogen utilization of Ac layers (black-boned chicken)
A study was conducted to evaluate the effects of dietary total sulphur amino acids (TSAA) to lysine (Lys) ratio on performance of Ac layers (black-boned chicken). A total of 800 laying hens from 38 to 50 weeks old was allocated…
Effect of level of inclusion of clove (Syzygium aromaticum) powder in the diet on growth and histological changes in the intestines and livers of broiler chickens
The study was designed to evaluate the effects of different levels of clove (Syzygium aromaticum) powder in the diet on growth performance and histological changes of the livers and intestines of broiler chickens at 21 and 35 days old. Three…
Feeding sodium selenite and nano-selenium stimulates growth and oxidation resistance in broilers
Nano-elemental selenium (nano-Se) has attracted more attention than sodium selenite (SS), owing to its low toxicity, high bioavailability, strong adsorbing ability and high catalytic efficiency. The purpose of the present study was to examine the effects of dietary supplementation with…
Increasing the productivity of Morkaraman sheep through crossbreeding with prolific Romanov sheep under semi-intensive production systems (Short communication)
The aim of this study was to evaluate the effects of cross-breeding Turkish indigenous Morkaraman (M) ewes with prolific Romanov (R) rams on the reproduction and performance traits, growth traits, slaughter and carcass characteristics of the crossbred offspring under semi-intensive…
Effect of production system and slaughter age on some production traits of guinea fowl: Meat quality and digestive traits
Certain meat quality traits of guinea fowl that were reared in two production systems were determined in this study. Grey guinea fowl were reared in free-range and barn conditions. Birds were slaughtered at 14, 16 and 18 weeks old to…
Co-products in maize-soybean growing-pig diets altered in vitro enzymatic insoluble fibre hydrolysis and fermentation in relation to botanical origin
The study examined the effects of botanical factors and fermentation-based, high-level dilution of co-product feeds in maize–soybean growing-pig diets on enzymatic insoluble fibre hydrolysis and fermentation. Feed insoluble fibre residues that were recovered after pepsin-pancreatin digestion were subjected to Roxazyme®…
Effect of probiotics, Saccharomyces spp.Kb-5 and Kb-8, in diets on growth performance and cholesterol levels in ducks
The study was conducted to determine the effect of the probiotics, Saccharomyces spp.Kb-5 and Saccharomyces spp.Kb-8, on growth performance, carcass characteristics, serum and meat cholesterol levels in ducks. Two hundred and forty 1-day-old healthy male ducks were randomly allocated to…
Hydrogen peroxide concentration and DNA fragmentation of buffalo oocytes matured in sericinsupplemented maturation medium
This study was conducted to investigate the effects of sericin on meiotic maturation, hydrogen peroxide (H2O2) concentration and deoxyribonucleic acid (DNA) fragmentation in buffalo oocytes. Oocytes were matured in vitro in tissue culture medium (TCM199) with in vitro maturation (IVM)…
Prebiotic effects of oligosaccharides extracted from palm kernel expeller on different levels of Salmonella typhimurium infection in chicks
Prebiotic effects of oligosaccharides extract from palm kernel expeller (OligoPKE) on Salmonella typhimurium were investigated in chicks in two experiments. Results of the first experiment showed that OligoPKE reduced the colonization of Salmonella typhimurium in the cecum and increased the…
Effect of feeding regime on the performance and blood parameters of male and female broiler chickens
The aim of the present study was to evaluate the effect of feeding regime on changes in growth, mortality, carcass composition, and blood parameters of male and female broiler chickens during feed restriction and the realimentation period. In the experiment,…
Effects of transportation and storage duration of Japanese quail eggs on hatchability
This study was conducted to investigate the effects of transportation from breeder’s farm to hatchery, and of storage duration on the hatchability of quail eggs. Hatching eggs were divided into two groups. The first group was stored for seven days…
Genotype imputation as a cost-saving genomic strategy for South African Sanga cattle: A review
Genetic variability in a population of Letelle sheep in South Africa
The purpose of the study was to gain insight into the genetic variability of the Letelle sheep breed, a breed that has been managed as a closed population for 90 years, with no new genetic material being permitted into the…
