The Faculty of Natural and Agricultural Sciences has reorganised three of its departments, and as a result the Departments of Animal Science, Microbiology and Biochemistry, and Sustainable Food Systems and Development have been established.

In a continuous effort to inspire excellence and transform lives, the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) has reorganised three of its departments. The entities that were affected include what was known as the Department of Consumer Science; the Department of Animal, Wildlife and Grassland Sciences; and the Division of Food Science.

The Department of Animal, Wildlife and Grassland Sciences has changed to Animal Science, while the Department of Consumer Science and the Centre for Sustainable Agriculture, Rural Development, and Extension (CENSARDE) merged to become the Department of Sustainable Food Systems and Development.

Sustainable food systems

Both the Department of Consumer Science and CENSARDE are major contributors to studies on food systems. According to Prof Johan van Niekerk, Head of the new Department of Sustainable Food Systems and Development, the two academic entities create a natural link that provides the potential for training, development, and research from a food systems perspective to benefit the local and national agri-business sector. 

Prof van Niekerk elaborates: “Food systems can be defined as the processes involved in providing food, fibre, and fuel products. These processes include growing, harvesting, processing, preparing, packaging, transporting, marketing, consumption, and waste management.”

“In terms of the academic structure at the UFS, the processing, preparing, and packaging of food resided within the Department of Consumer Sciences. The processes of growing, harvesting and food production, on the other hand, resided within the Centre for Sustainable Agriculture. The newly established Department of Sustainable Food Systems and Development holds the potential to combine the academic expertise of two separate entities into an interdisciplinary body that focuses on sustainable food systems from a holistic perspective.”

Relevant on a global scale

According to Prof Frikkie Neser, Head of the now Department of Animal Science, it is a worldwide phenomenon that Animal Science and all its related disciplines are classified under the name Animal Science.

As part of the changes in this discipline, Meat Science, Dairy Science, and Wool Science will again be presented within the department. Meat scientist, Prof Arno Hugo, and dairy scientist, Dr Koos Myburgh, and their support staff also joined the department. 

According to Prof Neser, the changes will also lead to the establishment of a Meat and Dairy Unit, an Animal Breeding Genomics and Bioinformatics Unit (ABGB), and a Dairy Processing Unit. The latter will be hosted on the Paradys Experimental Farm outside Bloemfontein.

Prof Neser says that changes to the department will simplify the curriculum without compromising the quality of the content or the professional registration of Animal Science students.

“Students will be exposed to the full value chain in meat, dairy, and wool, and research and product development can be conducted in our own fully equipped facilities,” says Prof Neser.

The changes will also lead to a better service to the industry. “Quality as well as chemical and microbial composition of meat will be tested for the whole meat industry. A similar service will also be provided for the dairy industry,” he says.

“A consulting service will also be available,” adds Prof Neser.

Furthermore, he says that the ABGB Unit will provide a statistical and analytical service to the university and the industry. “With the unit, it is possible to create a research facility that can coordinate and enhance all animal breeding research in the country, which will help South Africa to remain relevant on a global scale.”

As much as it will have a global footprint, the department will also add value on a local basis by presenting short courses in all disciplines for both commercial and emerging farmers, as well as the community as a whole.

“We will also continue to build on relationships with other universities, research and government institutions,” says Prof Neser.

Changes to Division of Food Science 

Another significant change that took place in the faculty was in the Division of Food Science. With the changes taking place in the Division of Food Science, the Department of Microbial, Biochemical and Food Biotechnology is now known as the Department of Microbiology and Biochemistry.

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
