The South African Society for Animal Science (SASAS) has changed the way the journal submission process is handled. An Online Journal Management System had been developed in collaboration with the Agricultural Research Council (ARC) 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 sajas.eic@gmail.com.

Nutrient contents and in vitro digestibility of different parts of corn plant
The objective of this study was to assess the nutrient contents and in vitro true digestibility (IVTD) of parts of the corn plant. The corn used in the study was P2088, a variety that is grown widely in Turkey. It…
Effects of polymorphisms in the endothelin receptor B subtype 2 gene on plumage colour in mule ducks
The aim of the present study was to investigate the effect of a single nucleotide polymorphism (SNP) of the endothelin receptor B subtype 2 (EDNRB2) gene on plumage coloration in mule ducks. Test mating (white Tsaiya × white Muscovy ducks)…
Assessment of genetic variation in Bapedi sheep using microsatellite markers
This study was conducted to assess genetic variation in Bapedi sheep using 14 microsatellite markers. Blood samples were collected from 174 unrelated Bapedi sheep on six farms in various districts of Limpopo and from the Agricultural Research Council Animal Production…
Genetic evaluation and selection correlated response of growth traits in Japanese quail
Objectives of the current study were to i) investigate effects of selection for bodyweight at four weeks old on bodyweight (BW) and bodyweight gain (BWG) across four generations; ii) estimate correlated response to selection for BW and BWG at different…
In situ dry matter, protein and neutral detergent fibre degradation kinetics of Cholistan Desert grasses
Global climate change is evident and poses serious threats to the sustainability of traditional rangeland livestock production systems. This study tested the feeding potential of perennial grasses of Cholistan Desert for various species of ruminants at different physiological stages. Eight…
Association of polymorphisms of vasoactive intestinal peptide and its receptor with reproductive traits of turkey hens
The aim of this study was to identify variations of vasoactive intestinal peptide (VIP) and VIP receptor-1 (VIPR-1) genes that might be associated with turkey reproductive traits. One hundred twenty turkey hens were recorded for age at first egg (AFE),…
Antibiotic-free diet supplemented with live yeasts decreases inflammatory markers in the ileum of weaned piglets
Emerging bacterial resistance to antibiotics increases the need for effective alternatives to control intestinal inflammation and thus gut disorders in piglets. This study evaluated the effects of including Saccharomyces cerevisiae (strain 1026) and Saccharomyces boulardii (CNCM I-1079) as antibiotic alternatives…
Genetic effects from an Afrikaner, Bonsmara, and Nguni three-breed diallel and top-crosses of Angus and Simmental sires
Individual and maternal breed additive effects and heterosis exist for most economically important traits in cattle. Crossbreeding may therefore be valuable for emerging and commercial beef farmers in improving the productivity of their herds. Calves were produced by mating Afrikaner,…
Evaluation of three fast- and slow-growing chicken strains reared in two production environments
The present study evaluated performance, physiological response and economics of commercial fast growing (CFG), commercial slow growing (CSG), and Rhode Island Red (RIR) chickens under intensive and free-range rearing environments. After 21 days of rearing under the same intensive environment…
Use of phosphatidylcholine in Tris-based extender with or without egg yolk to freeze Bapedi ram semen
Traditionally, egg yolk is a protective agent that is used to freeze semen in various species. However, the addition of egg yolk in extender risks the introduction of disease. Therefore, an alternative cryoprotective agent should be found to preserve ram…
Oxalate and silica contents of seven varieties of Napier grass (Pennisetum purpureum)
Oxalate and silica are considered antinutrients. Large quantities of oxalate and silica in plants can interfere with the uptake of essential minerals in ruminants. Therefore, the aim of this study was to compare the total silica and oxalate contents of…
Incorporating oldman saltbush hay and prickly pear in diets for red Sindhi calves
This study was designed to evaluate the nutrient intake, digestibility, degradability, and ruminal characteristics of Sindhi heifers fed diets that contained a combined total of 75% oldman saltbush hay (hereafter saltbush hay) and prickly pear cactus. Eight 12-month old intact…
Effect of arbuscular mycorrhizal inoculation on the quality and in vitro gas production of einkorn wheat straw
The purpose of this study was to determine the effects of arbuscular mycorrhizal (AM) inoculation on the quality of einkorn wheat straw (EWS) and in vitro gas production (GP). It was found that AM inoculation of EW seed before sowing…
Effects of supplementing geese with green sweet sorghum stalks on microbiota in segments of the gastrointestinal tract
To explore the effects of supplementing a basal diet with green sweet sorghum stalks on the gut microbiota in geese, one hundred and twenty 28-day-old geese were divided into two groups. Group 1 was fed a basal diet and group…
Effect of parity on reproductive performance sows of different breeds
The aim of this study was to determine the effect of parity on reproductive performance by sows of different breeds. The sows were raised on three farms, and had seven or more litters of not fewer than seven piglets. A…
Supplementation of Holstein dairy calves fed two levels of crude protein with methionine and lysine
This study aimed to investigate various levels of crude protein (CP) in starter diets and their supplementation with amino acids (AAs) on efficiency, health, and serum metabolites of dairy calves. Ninety-six newborn Holstein calves were allocated to eight treatments, namely…
Determination of the best non-linear function to describe the growth of Kajli sheep
The aim of the present study was to determine the best non-linear growth function to describe the growth of Kajli sheep. For this aim, the Brody, von Bertalanffy, Logistic, and Gompertz models were used to describe the sigmoidal relationship between…
Effect of partial replacement of soybean and corn with raw or processed chickpea
This study was conducted to investigate the effects of using raw and processed chickpeas in various ways and levels in rations of egg-laying quail on egg yolk fat content, egg yolk fatty acid profile and some blood parameters. Chickpeas were…
Forage allowances offered to pregnant ewes until middle and late gestation: Organ priorities on foetus development
Effect of forage allowance before conception and until mid or late gestation was evaluated for effects on foetal and neonatal weights, carcass, nervous systems, metabolic and reproductive organ weights, body dimensions, and variation in intensity of the effects among organs.…
Defatted yellow mealworm larvae (Tenebrio molitor l.) meal as possible alternative to fish meal in quail diets
The effects of replacing fish meal (FM) in the diet with defatted mealworm larvae meal (DMLM) on growth, carcass, and biochemical constituents of serum of Japanese quail chicks were investigated. A total of 600 unsexed one-day-old chicks were allotted to…
