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.

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
