The Department of Animal Science at the University of the Free State (UFS) walked away with numerous awards at the 52nd congress of the South African Society for Animal Science (SASAS).

Dr Foch de Witt, Senior Lecturer in the department, explains that the SASAS congress is an annual event where scientists, academics, students, and various industry role players come together to share the latest research findings regarding different aspects of animal science and production. 

Acknowledging greatness

The SASAS Gold Medal was awarded to Prof Michiel Scholtz, affiliated professor in the department. “He was presented with this award for his honourable lifelong service to animal science. His scientific contributions and achievements have been recognised as exceptionally meritorious by both national and international animal scientists,” says Prof Frikkie Neser, Head of the Department of Animal Science.

Andries van der Merwe, a postgraduate student, received the SASAS Student Postgraduate Merit Award. According to Prof Neser, this is an annual national merit award to postgraduate students for exceptional academic achievement in Animal Science during undergraduate studies at any South African university.

Dr Sinobongo Mdyogolo, a PhD student of Prof Neser, was presented with the SASAS Bronze Medal in respect of her PhD achievements in the research and technology transfer categories. This is the highest honour a student can get after completion of their PhD degree.

During the SASAS congress, a total of 22 oral and poster contributions were delivered by staff and students from the Department of Animal Science.

A great networking opportunity 

Another highlight for the department was when three of its students – Carina le Roux, Ofhani Mavhungu, and Andries van der Merwe – participated in and won the SASAS national student quiz. Team UFS was one of 13 student teams from various tertiary institutions participating in the competition. The external panel of judges complemented the team on how they integrated theoretical principles in a practical and applied manner.

According to Dr De Witt, UFS Animal Science graduates compare very favourably with other students from tertiary institutions in South Africa. “Many of our students seek employment in the animal feed industry and they excel in their professional career development. It is clear that the curriculum updates of the past few years were successful in ensuring that students are able to integrate theoretical and practical concepts in an applied manner – a skill that is sought after in the industry,” he says. 

He also believes that an event such as the SASAS congress is an ideal network opportunity where students can get exposure to congress presentations, while having the opportunity to meet potential employers and/or sponsors.

“The SASAS congress creates a platform for students to measure themselves in terms of scientific development and career preparedness by interacting directly with other students from different tertiary institutions as well as industry members. Exposure to events such as this furthermore prepares them for their professional registration with the South African Council for Natural Scientific Professions (SACNASP),” adds Dr De Witt.

Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
