Investigation into the relationship between leptin genotypes, body condition and carcass traits of Nguni and Hereford cattle.
Leptin, a 16 (kilo Dalton) kDa hormone secreted predominantly by white adipocytes, regulates reproduction, energy intake and expenditure, and is involved in immune system function. Previous studies have identified associations ...
Characterisation of the divergence of the Elsenburg Merino resource flock.
The Elsenburg Merino flock has been divergently selected for the ability of ewes to rear multiple offspring since 1986. Updated genetic trends for reproduction are reported for the Elsenburg Merino resource flock. The ...
Population genetics of Swakara sheep inferred using genome-wide SNP genotyping.
The pelts of Swakara sheep breed of Namibia are famous for their lustrous features and are unmatched in quality across the globe. These pelts occur in four subpopulations of white, grey, black and brown. The white pelt is ...
Estimation of genetic and demographic parameters of extensively raised chicken populations using genome-wide single nucleotides polymorphism (SNP) data.
Village chicken populations are raised under a farming system that faces a number of challenges such as small flock size, lack of animal performance and pedigree records, lack of proper husbandry and poorly defined and ...
Prevalence and antibiotic sensitivity of enterotoxigenic Escherichia coli isolates in South African pig population.
Escherichia coli (E. coli) are among the leading bacterial causes of diarrhoea and edema in newborn and weaned pigs. Pathogenic strains of E. coli are classified into enterotoxigenic E. coli (ETEC), enterohemorrhagic E. ...
Analyses of lipidic bodies from green microalgae.
This study presents the analyses of oil body components in microalgae which may be involved in oil droplet assembly including certain triacylglycerol precursors which can be processed to biodiesel, an alternative fuel ...
Novel cationic lipoplexes : characterization in cell culture in vitro and in vivo.
Amongst the more promising non-viral DNA vehicles are liposomes, with those derived from cationic lipids showing significant potential, despite moderate transfection levels in vivo. This study has investigated the effect ...

Genetic diversity of some Moringa oleifera Lam. cultivars available in South Africa.
Moringa oleifera Lam. (Moringaceae) is a nutritious and high medicinal value tree. The species is native to India but grown globally due to its properties. The nutritional content of the species includes high levels of ...
