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.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
