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.

Extending new discoveries in the deep subsurface – UFS paper published in Nature Communications
2015-11-30



Scanning electron microscopy of some of the Eukarya recovered from two different mines. (a) Dochmiotrema sp. (Plathyelminthes), (b) A. hemprichi (Annelida), (c) Mylonchulus brachyurus (Nematoda), (d) Amphiascoides (Arthropoda). Scale bar, 50 µm (a,b), 100 µm (c), 20 µm (d).

Following the discovery of the first Eukarya in the deep subsurface (Nature, 2010) by a research group from the Department of Microbial, Biochemical, and Food Biotechnology at the University of the Free State (UFS) and their international collaborators, intense interest has developed in understanding the diversity of more complex organisms living in these extreme environments.

Prof Gaetan Borgonie from Extreme Life Isyensya, together with a group of UFS researchers, took this research further, resulting in a paper on this research released in Nature Communications – impact factor 11.47.  This paper is an extension of the first reports of more complex life at great depths, and their abilities to survive these harsh conditions.

Ten authors from the UFS contributed with the array of expertise needed to define this discovery. The group was supported by staff from the different mining groups, long-term leading collaborators from the USA and Canada, and the idea specialist driver of the paper, Prof Borganie.

“After a sampling campaign that lasted more than two years, we identified that Platyhelminthes, Rotifera, Annelida and Arthropoda are thriving at 1.4 km depths in fissure water up to 12,000-years old in the South African mines of Driefontein and Kopanang,” said Prof Borgonie, who was appointed as associated researcher in the Department of Microbial, Biochemical, and Food Biotechnology.

This paper really opens a “can of worms” so to speak. According to Prof Esta van Heerden from the Department of Microbial, Biochemical and Food Biotechnology at the UFS they extended to define protozoa and fungi. “However, they are present in low numbers,” she said.

Characterisation of the different species reveals that many are opportunistic organisms. In house-adapted video equipment was used to film inside the fissure for the home of the organisms.

This is the first-known study to demonstrate the in situ distribution of biofilms on fissure rock faces using video documentation. Calculations suggest that food, not dissolved oxygen, is the limiting factor for population growth. The discovery of a group of complex multicellular organisms in the underground has important implications for the search for life on other planets in our solar system.
