Experimental farm
The Paradys Experimental Farm donated 428 bales of animal feed to farmers who lost veld in the Fauresmith and Tierpoort districts.

“I wish I had more to give.” These are the words of Johan Barnard, Junior Lecturer and manager on the Paradys Experimental Farm of the University of the Free State (UFS) after he donated the last of 428 bales of animal feed to a farmer from the Tierpoort area this morning (4 August 2021).

After large parts of the Paradys Experimental Farm were destroyed by veld fires three years ago and 24 famers came out to help fight the fire, Barnard believes in planting a surplus of food that would enable him to share with farmers in need. Last year, he donated bales of animal feed to farmers in the Hertzogville district whose veld was destroyed.

Sharing resources

More recently – less than a month ago – veld fires destroyed thousands of hectares of land in the Tierpoort and Fauresmith districts. Barnard, who helped to put out the fires and saw the destruction, decided to make the extra animal feed available to the farmers who needed feed for their animals.

Together with research and teaching and learning, the community is one of the university’s focus areas. “As a university, we are sharing our knowledge. The destruction brought about by the veld fires has created an opportunity where the university can also share its resources,” says Barnard.

When he made the decision to help, the feed was, however, still on the fields and had to be cut, processed, and baled. But where there is a will and a community that stand together, there is a way.

The farmers in the Koppieskraal district brought their tractors and machinery to cut, rake, and bale the sorghum and grass. BKB contributed fuel to cover the running costs of the tractors and machinery.

Once the animal feed was baled, Barnard contacted Jack Armour, operations manager at Free State Agriculture, who not only spread the word to farmers that animal feed was available, but also provided fuel to deliver the bales to the farms destroyed by fires. Since last week, volunteers have come to collect the animal feed and distribute it to the farmers.

Barnard, who believes it is difficult to put a price value on the animal feed provided by the university, says to the farmers who received it, the value of these bales is priceless.

A priceless gift

Besides the thousands of hectares of pasture destroyed during the raging fires, farmers also lost a significant number of sheep and cattle. When Leon Kruger, Lecturer in the Department of Animal Science, on the experimental farm, saw the devastation caused by the fires, he posted on Facebook that he was available to assist in treating the animals.

Together with two government veterinarians and a colleague from the Glen Agricultural College, Kruger drove hundreds of kilometres to farms in the south and southwestern Free State to help farmers treat animals affected by the fires.

He says they have treated more than 800 animals, including sheep and cattle. “We treated the animals one by one, administering antibiotics and pain medication, as well as ointment to the burned areas. This difficult ordeal was, however, a baptism of fire for all of us; we are not familiar with burn wounds. A friend in Australia helped to compile criteria to classify the different degrees of burn wounds and we treated the animals accordingly.”

“Seeing the suffering of the animals was one of the most difficult ordeals I had to experience,” states Kruger, who helped several farmers save their animals during this time where they have already lost so much.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
