Adding to the value chain, extending the teaching and learning process, and supporting the development of the surrounding communities – this is the result of seven years of hard work for the Paradys Experimental Farm of the University of the Free State (UFS). Whether it is yoghurt and cheese from the dairy factory, wool products from the wool production and wool processing hub, or an ice-cold beer from the fermentation institute, the farm will soon share the fruits of its labour with the Bloemfontein community.

Situated outside Bloemfontein on the road to Reddersburg, the farm is an agricultural training centre in the Faculty of Natural and Agricultural Sciences for UFS students who, among others, take modules in agriculture, working with cattle, sheep, crop cultivation, and milk production. Moreover, the farm also offers training opportunities to members of the community, ranging from short courses in animal health and animal breeding to workshops in wool classing, sheep handling, and sheep management. 

“We want to take students through the entire production chain. It is a valuable part of our teaching and can make our work on the farm more profitable. The aim is to extend the use of a specific product. Instead of only selling milk, we add value to the product and sell it, for instance, as cheese or yoghurt. Or in the case of grain, rather than only selling it to wholesalers to make bread, it can be fermented into beer and waste can be used as animal feed,” says Prof Frikkie Neser, Head of the Department of Animal Sciences. He is the convenor of this initiative, along with the Dean of the Faculty of Natural and Agricultural Sciences, Prof Danie Vermeulen.

Currently, eight departments in four of the faculties at the UFS are involved in the work on the experimental farm. 

Natural products in the dairy processing unit

Dr Analie Hattingh, Manager of the dairy processing unit and Lecturer in the Department of Animal Science, is responsible for the entire production process in the dairy processing unit, from concept development up to sales. Since the installation of the unit started in May 2021, two lines of cheese have been produced – a delicious semi-hard, full-cream all-rounder, and a more exotic cheese with different flavours, containing ingredients such as cumin, chili, garlic, peppercorns, and mango. The Department of Sustainable Food Systems and Development (CENSARD) will later cultivate and harvest some of these herbs in the tunnels on the experimental farm. The department will also be involved in product development.

More recently, Dr Hattingh also started to investigate the development of a yoghurt line with different flavours – the more traditional mixed fruit and strawberry, as well as more exciting flavours such as pear caramel.   

“All our products are natural,” she says. 

This initiative adds to the already established centralised infrastructure hub on the experimental farm, which supports wool production and processing. Under the auspices of CENSARD, members from the community are taught, among others, entrepreneurial skills in different aspects of wool processing, such as knitting, making felt products, spinning, and weaving.

bookbags, tray cloths, and soft toys.

Creating products from dairy and wool is not only contributing to job creation; it also empowers communities to create a sustainable livelihood for themselves.

Award-winning beer 

Award-winning beer makers Dr Errol Cason, Senior Lecturer in the Department of Animal Science, and Dr Christopher Rothmann, postdoctoral research fellow in the Department of Animal Sciences, are looking forward to opening a fermentation institute on the Paradys Experimental Farm. 

With their background as microbiologists, the two founders of Liquid Culture (in 2018) produced commercial batches of yeast used mainly by breweries for the fermentation of beer. They are supplying Bloemfontein as well as several breweries nationwide with their quality yeast. 

At the fermentation institute on the farm, these home brewers and owners of Kraft Brewing Co hope to not only continue brewing bear, but to also teach others about the fermentation process. Installation of the vessels, which were previously part of the South African Brewery’s World of Learning, is almost complete.

Entrepreneur science park 

Prof Neser says they are also in the process of constructing an entrepreneur (science) park for students in the sciences. Upon completion, the park will boast nine containers with the necessary infrastructure for students to work on innovation projects – promoting an entrepreneurial culture at the UFS. 

The farm will also provide a service to the agriculture industry by testing feed intake and growth rate in cattle, evaluating these animals’ efficiency in converting feed to body mass. Prof Neser says the UFS is the only university conducting these tests on cattle. Similar trials will also be conducted on sheep, in collaboration with BKB, ALPHA, and RFID.

Grass has been planted in the open areas, and trees and tables with benches are planned to create a welcoming space for school groups to visit during the week in order to learn about the wool and dairy value chain. Members of the community will also be invited to display and sell their products on Saturdays, along with the goods produced on the farm. The scene is set, and soon all projects will benefit not only UFS staff and students, but also the community.

Plant scientists address wheat rust diseases at SASPP congress

In his research, Dr Botma Visser, researcher in the Department of Plant Sciences at the University of the Free State, highlighted the population dynamics of the stem rust fungus (Puccinia graminis f. sp. tritici) in Southern Africa. In recent years, two foreign stem rust races were introduced to South Africa, and a local virulence adaptation occurred in a third.

All of these races form part of the Ug99 group, a highly virulent collection of rust races endangering wheat production in many parts of the world. Despite the fact that half of the members of the Ug99 race group is prevalent in South Africa, Dr Visser’s work has clearly shown that Ug99 did not have its origin here. This emphasised the need to include neighbouring countries in the annual stem rust surveys, to proactively identify new races that could threaten local wheat production. In his research, Dr Visser also mentioned the way in which he has optimised modern molecular tools to accurately detect Ug99 isolates.

Dr Visser is one of three scientists from the Department of Plant Sciences that addressed delegates attending the biennial congress of the Southern African Society for Plant Pathology (SASPP) on the Bloemfontein Campus earlier this month on progress regarding research on wheat rust diseases conducted at the UFS.

Howard Castelyn, a PhD student in Plant Sciences, presented his research on quantifying fungal growth of the stem rust pathogen in wheat varieties displaying genetic resistance. This resistance, which is best expressed in adult plants, has the potential to remain durable in the presence of new rust variants. His presentation at the congress focused on optimising microscopic and molecular techniques to track fungal development in stem tissues of adult plants. These results now allow scientists to link rust infection levels and cellular responses with particular resistance genes expressed by the wheat plant, and contributing to the understanding and exploitation of durable resistance.

Prof Zakkie Pretorius presented his research, explaining how new genetic diversity for resistance to the stripe (yellow) rust fungus (Puccinia striiformis) is discovered, analysed and applied in South Africa. This research, conducted in collaboration with Dr Renée Prins and her team at CenGen, is unravelling the genetic basis of stripe rust resistance in a promising wheat line identified by Dr Willem Boshoff, a plant breeder at Pannar. The line and DNA markers to track the resistance genes will soon be introduced to South African wheat breeding programmes.

The rust research programme at the UFS contributes significantly to the successful control of these important crop diseases.

In addition to the contributions by the UFS, rust fungi featured prominently at the SASPP, with first reports of new diseases on sugar cane and Acacia and Eucalyptus trees in South Africa. A case study of the use of a rust fungus as a biological control agent for invasive plant species in the Western Cape, was also presented.
