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

Genetic diversity in Zimbabwean Sanga cattle breeds using microsatellite markers
Zimbabwe’s smallholder land-based livelihoods are dominated by the three local Sanga cattle breeds, namely Mashona, Tuli, and Nkone. A study was carried out to determine genetic diversity and differentiation among conservation populations of these breeds using 16 bovine-specific microsatellite markers.…
Effects of chitosan addition on growth performance, diarrhoea, anti-oxidative function and serum immune parameters of weaned piglets
The present experiment was designed to determine the efficacy of a commercial source of chitosan (CS) to enhance performance, anti-oxidative function, and immune response in weaned pigs. A total of 60 crossbreed piglets (Duroc × Landrace × Yorkshire), with average…
Effects of sesame meal on intake, digestibility, rumen characteristics, chewing activity and growth of lambs
Two experiments were carried out to determine ruminal degradability of sesame meal (SSM) and its effects on intake, digestibility, rumen parameters, chewing activity, and lamb performance when it replaced soybean meal (SBM). Degradability of dry matter (DM) and crude protein…
The influence of different dietary energy concentrations on the production parameters of feedlot ostriches
Energy is essential for the continuous survival of any living organism. In ostrich diets, energy is usually derived from maize, which is often subject to fluctuations in yield as a result of drought conditions. Therefore, the optimal utilization of energy…
Feed preference of grower ostriches consuming diets differing in Lupinus angustifolius inclusion levels
Feed costs contribute the largest proportion of the input costs of slaughter birds in an intensive ostrich production unit. Alternative, cheaper feedstuffs, such as lupins (sweet and bitter cultivars), were therefore evaluated to determine the optimal lupin inclusion level in…
Effects of varying sweet lupin dietary inclusion levels on feather classes, leather traits and meat composition of feedlot ostriches
The main consumer products derived from ostriches are feathers, leather and meat. Despite progress in optimizing production practices, additional information is still necessary about the value of various raw materials as feed to ensure cost-efficient production. This study aimed to…
Enhancement of poultry meat: Trends, nutritional profile, legislation and challenges: A review
Poultry meat is a good source of animal protein, and is affordable for many low-income families in developing countries. It is also part of a balanced diet through contributing valuable nutrients for human health. The poultry industry implements an enhancement…
Production and profitability of a beef herd on transitional Cymbopogon-Themeda veld receiving three levels of lick supplementation
The purpose of the study was to investigate the effects of three levels of lick supplementation on the production and reproduction of cows grazing transitional Cymbopogon-Themeda veld. The study was conducted over three years (2011–2014). A total of 150 Drakensberger…
Quantification of the uterine involution and dimensions, hormonal response and reproductive performance of pyometric and healthy dairy cows treated with Dinoprost
The aim of the present study was to investigate the effects of a PGF2α analogue (Dinoprost) on involution of the puerperal uterus, especially with pyometra during 35 to 45 days postpartum in multiparous high yielding Holstein dairy cows. At days…
Layer performance, fatty acid profile and the quality of eggs from hens supplemented with Moringa oleifera whole seed meal
The objective of the study was to determine how the partial supplementation of Moringa oleifera whole seed meal (MOWSM) would affect layer performance, egg quality and egg fatty acid profile. One hundred and forty-four Hy-Line hens in early-lay (20-weeks-old), with…
Effects of a fibrolytic enzyme and bacterial inoculants on the fermentation, chemical composition and aerobic stability of ensiled potato hash
The study was conducted to evaluate the effects of adding a fibrolytic enzyme in combination with bacterial inoculants on the fermentation, chemical composition and aerobic stability of ensiled potato hash (PH). Potato hash silage (PHS) was produced by mixing 800…
Potential of white garlic powder (Allium sativum L.) to modify in vitro ruminal fermentation
The current study aimed to evaluate the effect of increasing doses of garlic powder (GaP) on in vitro fermentation characteristics. Two successive 24-hour incubations were run, and gas production was measured at the end of each incubation period. Liquid samplings…
Gene expression and maturation evaluation of sheep oocytes cultured in medium supplemented with natural antioxidant source
Any improvements in assisted reproduction techniques at experimental level are important in in vitro production of large animal and human embryos. The in vitro embryo production system includes three major steps, namely in vitro maturation of the primary oocytes, in…
Effect of Acacia angustissima leaf meal on performance, yield of carcass components and meat quality of broilers
The study determined the appropriate levels of including Acacia angustissima leaf meal in broiler diets for optimum performance, carcass part yield, and meat quality characteristics. One hundred and fifty broiler chicks were allocated to 0%, 5%, and 10% A. angustissima…
Feed intake, growth performance and carcass traits of broilers fed diets with various inclusion levels of baobab seed oilcake
The effects of increasing dietary inclusion levels of baobab seed oilcake (BSOC) on the growth performance, carcass characteristics, and yield in Ross 308 broiler chicks were assessed. Dietary treatments (T) consisted of four levels of BSOC: T1, control (0% BSOC);…
