Andries van der Merwe was presented the Koos van der Merwe AFMA Student of the Year Award as the most outstanding final-year student in Animal Nutrition in 2021/2022.

Since childhood, a love of animals, nature, and agriculture has been instilled in Andries van der Merwe. He used to accompany his father, the local veterinarian in Postmasburg, helping where he could. “I can still vividly remember the first C-section I helped him with when I was about 12,” he says. 

A few years later, Andries decided to enrol for his studies at the University of the Free State (UFS) in order to get his grades up to study veterinary medicine one day. “But when I reached my third year and started with the subject Animal Nutrition, I saw that I could make a bigger difference and contribution to the agricultural sector through nutrition. The moment I realised this, my mind was made up to study towards becoming an animal nutritionist,” he says.

Viable alternative to the excessive use of antibiotics

His master’s thesis on the use of tannins as a feed additive to increase the production efficiency of ruminants (sheep, cattle, and goats) is also looking for a viable alternative to the excessive use of antibiotics to treat certain non-specific ailments such as diarrhoea and skin diseases.

With his work having the potential to one day make a difference in the agricultural sector, as well as some encouragement from his supervisor, Dr Ockert Einkamerer, Senior Lecturer in the Department of Animal Science, Andries entered and won AFMA’s Student of the Year competition. 

During a virtual symposium on 18 October 2021, the Animal Feed Manufacturers Association (AFMA) presented Andries with the Koos van der Merwe AFMA Student of the Year Award as the most outstanding final-year student in Animal Nutrition in 2021/2022.

“I have no idea what could have impressed the judges”, says Andries, who competed with students from universities across South Africa. 

Making a contribution to animal feeding in South Africa

“I am the second student from the UFS to win this award. Gert Daniel Jacobus Scholtz received the award in 1998 – my birth year,” says Andries. 

“It is an enormous honour for me to receive this highly prestigious award. I believe that the exposure I receive due to this reward will help me to secure a position where I can make a valuable contribution to the industry much quicker,” he adds.

De Wet Boshoff, Executive Director of AFMA, commended Andries: “I wish to congratulate you on behalf of the Animal Feed Manufacturers Association (AFMA) on winning the award. I believe it will encourage you to – through further studies and your career in the future – make a contribution to animal feeding in the Republic of South Africa.”

The award consists of a certificate and a cash amount of R20 000 sponsored by AFMA.

Andries is planning on completing his master’s degree. “I am considering a PhD and a Master’s of Business Administration. The latter is to ensure that I will be a vital part of any company in the industry,” he says.

“What is meant to happen will happen … you just need to have faith,” he believes.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

17 September 2013

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.
