The Department of Animal Science at the University of the Free State (UFS) walked away with numerous awards at the 52nd congress of the South African Society for Animal Science (SASAS).

Dr Foch de Witt, Senior Lecturer in the department, explains that the SASAS congress is an annual event where scientists, academics, students, and various industry role players come together to share the latest research findings regarding different aspects of animal science and production. 

Acknowledging greatness

The SASAS Gold Medal was awarded to Prof Michiel Scholtz, affiliated professor in the department. “He was presented with this award for his honourable lifelong service to animal science. His scientific contributions and achievements have been recognised as exceptionally meritorious by both national and international animal scientists,” says Prof Frikkie Neser, Head of the Department of Animal Science.

Andries van der Merwe, a postgraduate student, received the SASAS Student Postgraduate Merit Award. According to Prof Neser, this is an annual national merit award to postgraduate students for exceptional academic achievement in Animal Science during undergraduate studies at any South African university.

Dr Sinobongo Mdyogolo, a PhD student of Prof Neser, was presented with the SASAS Bronze Medal in respect of her PhD achievements in the research and technology transfer categories. This is the highest honour a student can get after completion of their PhD degree.

During the SASAS congress, a total of 22 oral and poster contributions were delivered by staff and students from the Department of Animal Science.

A great networking opportunity 

Another highlight for the department was when three of its students – Carina le Roux, Ofhani Mavhungu, and Andries van der Merwe – participated in and won the SASAS national student quiz. Team UFS was one of 13 student teams from various tertiary institutions participating in the competition. The external panel of judges complemented the team on how they integrated theoretical principles in a practical and applied manner.

According to Dr De Witt, UFS Animal Science graduates compare very favourably with other students from tertiary institutions in South Africa. “Many of our students seek employment in the animal feed industry and they excel in their professional career development. It is clear that the curriculum updates of the past few years were successful in ensuring that students are able to integrate theoretical and practical concepts in an applied manner – a skill that is sought after in the industry,” he says. 

He also believes that an event such as the SASAS congress is an ideal network opportunity where students can get exposure to congress presentations, while having the opportunity to meet potential employers and/or sponsors.

“The SASAS congress creates a platform for students to measure themselves in terms of scientific development and career preparedness by interacting directly with other students from different tertiary institutions as well as industry members. Exposure to events such as this furthermore prepares them for their professional registration with the South African Council for Natural Scientific Professions (SACNASP),” adds Dr De Witt.

UFS researcher engineers metal surfaces

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
