Investigation of leptin genotypes and economically important dairy traits in jersey cows.
Dairy farming is one of the most important agricultural industries in South Africa, and thus improving the performance of dairy cows, with respect to economically important dairy traits, would be beneficial. Selection ...
Investigation of the utilization of microsatellites for fingerprinting in three endangered southern African crane species.
Cranes are large elegant birds that occur on all continents of the world except for South America and Antarctica. Of the fifteen species of crane worldwide, three predominantly occur in southern Africa; the Wattled crane ...
Computer simulation of marker-assisted selection utilizing linkage disequilibrium.
The face of animal breeding has changed significantly over the past few decades. Traditionally, the genetic improvement of both plant and animal species focussed on the selective breeding of individuals with superior ...
Individual identification and parentage analysis of Struthio camelus (ostrich) using microsatellite markers.
Ostrich (Struthio camelus) breeding is a well-developed industry in South Africa. However, successful genetic management has yet to be implemented. Parentage in colony breeding ostriches is unknown, where for a given ...
Testing the utility of DNA barcoding for the rapid assessment of Formicidae biodiversity in the eThekwini region.
The biodiversity of Durban (eThekwini municipality) in KwaZulu Natal is primarily threatened by urbanization although other factors such as climate change and the spread of invasive species also pose a significant threat. ...
The inhibition of Fusarium oxysporum f.sp. cubense race 4 by Burkholderia cepacia.
Inhibition of Fusarium oxysporum f. sp. cubense race 4 by Burkholderia cepacia was evident when grown on various media (TSA, PDA, PSA, YM, KMB, PPM, NYGA, LA) with different carbon sources and under various pH and ...

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 ...
Behavioural, reproductive and growth studies on Oreochromis mossambicus (Peters 1852)
A major obstacle facing the successful creation of an African aquaculture industry, based upon Oreochromids, is the irregular supply of good quality fish seed. There are several causative biological processes behind its ...
