"Experientia docet" - Experience is the best teacher

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

Effect of feeding duration of Spirulina platensis on growth performance, haematological parameters, intestinal microbial population and carcass traits of broiler chicks

  • 2018
  • Issue: 1
  • Volume: 48
S. Sugiharto, T. Yudiarti, I. Isroli & E. Widiastuti Page: 98 - 107

Spirulina platensis is a good candidate as an in-feed antibiotics substitute for broilers. However, its use seems impractical owing to its high price, especially when being administered throughout the whole rearing period. This study aimed to investigate the effects of…

Optimization of in vitro culture and transfection condition of bovine primary spermatogonial stem cells

  • 2018
  • Issue: 1
  • Volume: 48
A. Jafarnejad, M. Aminafshar, M. Zandi, M. R. Sanjabi & N. Emamjomeh Kashan Page: 108 - 116

The present study aimed to optimize the in vitro culture and transfection efficiency of bovine primary spermatogonial stem cells (SSCs). To this end, SSCs were obtained from newborn Holstein bull calves by two-step enzymatic digestion. After enrichment and culture, SSCs…

Assessment of genetic variation among four populations of Small East African goats using microsatellite markers

  • 2018
  • Issue: 1
  • Volume: 48
A. S. Nguluma, Y. Huang, Y. Zhao, L. Chen, G. Msalya, C. Lyimo, E. Guangxin & S. W. Chenyambuga Page: 117 - 127

The majority of goats in Tanzania belong to the Small East African (SEA) breed, which exhibits large phenotypic variation. This study aimed to determine the genetic structure of, and relationships among four populations (Sukuma, Gogo, Sonjo, and Pare) of the…

Genetic diversity in Zimbabwean Sanga cattle breeds using microsatellite markers

  • 2018
  • Issue: 1
  • Volume: 48
E. Gororo, S. M. Makuza, F. P. Chatiza, F. Chidzwondo & T. W. Sanyika Page: 128 - 141

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

  • 2018
  • Issue: 1
  • Volume: 48
Y. Q. Xu, Z .Q. Wang, Z. Qin, S. M. Yan & B. L. Shi Page: 142 - 150

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

  • 2018
  • Issue: 1
  • Volume: 48
B. Ghorbani, A. Teimouri Yansari & A. Jafari Sayyadi Page: 151 - 161

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…

Feed preference of grower ostriches consuming diets differing in Lupinus angustifolius inclusion levels

  • 2018
  • Issue: 1
  • Volume: 48
T. S. Brand, J. A. Engelbrecht, J. van der Merwe & L. C. Hoffman Page: 170 - 185

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

  • 2018
  • Issue: 1
  • Volume: 48
T.S. Brand, J.A. Engelbrecht, J. van der Merwe & L.C. Hoffman Page: 186 - 197

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…

Production and profitability of a beef herd on transitional Cymbopogon-Themeda veld receiving three levels of lick supplementation

  • 2018
  • Issue: 2
  • Volume: 48
L. A. Foster, P. J. Fourie & F. W. C. Neser Page: 213 - 221

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…
