Dr Jan Swanepoel believes that the agricultural sector must be assisted in every possible way to shift its focus from mere subsistence farming, as is still the case in many parts of the world, to sustaining the lives of millions of people on the planet.
17 October is marked as International Day for the Eradication of Poverty by the United Nations (UN). 

The University of the Free State (UFS) is involved in several initiatives aimed at empowering communities to create a sustainable livelihood for themselves in the long run.

One of these initiatives includes a project to build competitiveness for communal farmers by developing the wool value chain in the Free State. 

The UFS Centre for Sustainable Agriculture, Rural Development and Extension (CENSARDE) submitted a proposal to the Regional Universities Forum for Capacity Building in Agriculture (RUFORUM); their proposal was selected, and they were awarded a grant of US$300 000. 

Dr Jan Swanepoel, Senior Lecturer and Researcher at CENSARDE, says the world is moving from local and national markets towards a global system of trading. This means that neighbouring farmers working on small plots of land may be competing with large industrial farmers from another country in a single marketplace.

A drive to commercialise

He adds that in developing countries, there is increasing pressure on farmers to commercialise their operations. “In order to meet the drive for greater commercialisation, new skills must be developed to support farmers in becoming better entrepreneurs. Assistance towards infrastructure must be provided; and the needs of farmers, such as market access, must be identified and catered for.”

Dr Swanepoel points out that the agricultural sector must be assisted in every possible way to shift its focus from mere subsistence farming, as is still the case in many parts of the world, to sustaining the livelihoods of millions of people on the planet. 

“As the agricultural sector starts to realise this more fundamental role and responsibilities with regard to production, new strategies can be conceived towards the enhancement of the socio-economic status of all role players in the agricultural sector,” he says.

One of the industries that agriculture in South Africa can expand on, is the wool industry. 

“China is the biggest buyer of South African wool. During lockdown, no wool from South Africa was exported to China, causing the price of wool to drop significantly. Fortunately, the markets have opened up, the excess wool from Australia has been absorbed, and China is buying wool at full capacity now. Even though the price of wool is 30% below the price of last year, the markets are reacting positively, showing a steady increase. Wool buyers believe that this trend will continue due to international market demand exceeding the supply,” says Dr Swanepoel.

He also believes the creation of niche products from the wool will add to the existing value chain, creating more jobs and an opportunity for enlarging the export market.

Profitable and sustainable venture

CENCARDE is involved in an attempt to transform communal woolgrowers’ production from an underachieving enterprise to a profitable, sustainable, and renewable venture to enhance the livelihoods of communal wool producers. 

“In addition, with the extension of the value chain directly to consumers, job creation and development plays a vital role in supporting the South African National Treasury’s strategy,” adds Dr Swanepoel.

This project is thus built around the commercialisation of wool production in the communal areas of the Free State, by developing strategies to be implemented concurrently in order to attempt to manage the various challenges faced by these growers. 

As part of this project, a centralised infrastructure hub will be established on the UFS experimental farm to support wool production and processing. Woolgrowers, sheepshearers, and men and women from the community will also be equipped with the necessary skills and knowledge to operate in the wool industry. Adding to these skills, members of the community will be taught entrepreneurial skills in different aspects of wool processing, such as knitting, making felt products, spinning, and weaving. 

Another helpful aspect of this project is linking the communal woolgrowers to markets, and in so doing, giving them a collaborative advantage.

Educational benefits

However, not only communal woolgrowers will benefit from this programme. It also has educational benefits, as the project is designed to incorporate research. According to Dr Swanepoel, CENSARDE is very committed and are using this project as a pilot to demonstrate the potential for a more multidisciplinary, multi-stakeholder approach to education, research, and development. Fifteen students will directly benefit from this project, including two PhD and three master’s students.

Also adding value to the project is the development of private partnerships in the form of the Dohne Merino Breed Society, commercial farmers, and other key wool marketing agencies – which will assist with technical matters and knowledge – as well as the Free State Department of Agriculture.

All participants strive for more profitable and competitive communal woolgrowers in a changing global wool market. The project is not another educational exercise but will equip woolgrowers to change their circumstances for the better.

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
