Mr Godfrey Mahlatsi, Acting Head of the Free State Department of Health; Ms Montseng Tsiu, Free State MEC of Health; Ms Sisi Ntombela, Premier of the Free State; and Prof Francis Petersen, Rector and Vice-Chancellor, give the thumbs up to the vaccination centre at the Universitas Academic Hospital.

As a public institution, the University of the Free State (UFS) always wants to play a role in society through its expertise, facilities, and assets. It is for this reason that the university is assisting the Free State Department of Health to equip the vaccination centre at the Universitas Academic Hospital to function optimally as one of the primary vaccination sites in Bloemfontein. 

Prof Francis Petersen, Rector and Vice-Chancellor, says the university decided to assist the department by providing computers, chairs, tables, and installing network cables at the vaccination centre which opened on Monday May 24 2021. The recovery room where patients are monitored after being vaccinated was also equipped. The university’s School of Nursing is also training its students to help with the vaccination process. 

Prof Petersen, together with Prof Gert van Zyl, Dean of the Faculty of Health Sciences; Ms Sisi Ntombela, Premier of the Free State; Ms Montseng Tsiu, MEC of Health; and Mr Godfrey Mahlatsi, Acting Head of the Department of Health, paid a visit to the vaccination centre on Tuesday 25 May 2021. 

UFS part of the broader community 

“The UFS is a public institution and we always ask what our role in society is. We are part of the broader community so we need to play a role through our expertise, our facilities, and assets and see to what extent we can positively impact the community. This is a good example of doing that. COVID-19 is an opportunity for everyone to take hands and address it in a collaborative way.

“The UFS values our partners, and in this particular case, the Department of Health. We believe that if we can work with our partners, the impact would be that much greater. If this facility is full to capacity, we would be able to vaccinate about 3 000 people a day which would never have been achieved if we did not take hands,” says Prof Petersen.
According to him, the UFS will do the same in Qwaqwa by providing the same type of equipment. Prof Petersen also encourages South Africans, especially those over the age of 60, to register to be vaccinated. 

“It is also my role as leader of the institution to encourage people to register and get vaccinated, because if you do get COVID-19 again, the impact will be lighter. This is something that we need to fight and manage.”

People are excited to be vaccinated  
Premier Ntombela says the province is lucky to have the UFS as a partner. “The university has been with us since day one. We are very excited and lucky to partner with them. I think they are doing a wonderful job, not only with their expertise, but also with providing equipment for us to use. I am very happy that everything is going smoothly. Everyone wants to be vaccinated and people are excited.”

According to Dr Nicholas Pearce, Head of Surgery at the UFS – who is also heading the Universitas Hospital COVID-19-Task Team – their aim is to vaccinate between 1 500 and 2 000 people a day. “The UFS School of Nursing is busy training nursing students to assist us with vaccinating people. The university’s contribution is massive. We would not be able to do it without them,” says Dr Pearce.

Studies to reveal correlation between terrain, energy use, and giraffe locomotion
2016-11-18



More than half of giraffes in captivity in Europe are afflicted by lameness. This high prevalence represents an important welfare issue, similar to other large zoo animals.

According to Dr Chris Basu, a veterinarian at the Royal Veterinary College in the UK, giraffes in captivity are often afflicted by overgrown hooves, laminitis and joint problems. Diagnosis and treatment is limited by our understanding of anatomy and function, more specifically the locomotion of these animals. Although the giraffe is such a well-known and iconic animal, relatively little has been studied about their locomotor behaviour.

Dr Basu recently visited South Africa to do fieldwork on the locomotion of giraffes as part of his PhD studies under the mentorship of world-renowned Professor of Evolutionary Biomechanics, Prof John Hutchinson. This project is a joint venture between Dr Basu and Dr Francois Deacon, researcher in the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research. 

Together Prof Hutchinson and Drs Deacon and Basu form a research group, working on studies about giraffe locomotion.

Wild giraffe population decrease by 40% in past decade

“Locomotion is one of the most common animal behaviours and comes with a significant daily energetic cost. Studying locomotion of wild animals aids us in making estimates of this energetic cost. Such estimates are useful in understanding how giraffes fit into ecosystems. Future conservation efforts will be influenced by knowledge of the energy demands in giraffes.

“Understanding aspects of giraffe locomotion also helps us to understand the relationships between anatomy, function and evolution. This is relevant to our basic understanding of the natural world, as well as to conservation and veterinary issues,” said Dr Deacon.

Locomotion study brings strategy for specialist foot care

On face value it seems as if foot disease pathologies are more common in zoo giraffes than in wild giraffes. “However, we need a good sample of data from both populations to prove this assumption,” said Dr Basu. 

This phenomenon is not well understood at the moment, but it’s thought that diet, substrate (e.g. concrete, straw, sand and grass) and genetics play a part in foot disease in giraffes. “Understanding how the feet are mechanically loaded during common activities (standing, walking, running) gives our research group ideas of where the highest strains occur, and later how these can be reduced through corrective foot trimming,” said Dr Basu.

Through the studies on giraffe locomotion, the research group plans to devise strategies for corrective foot trimming. At the moment, foot trimming is done with the best evidence available, which is extrapolation from closely related animals such as cattle. “But we know that giraffes’ specialist anatomy will likely demand specialist foot care,” Dr Basu said.

Studying giraffes in smaller versus larger spaces

The research group has begun to study the biomechanics of giraffe walking by looking at the kinematics (the movement) and the kinetics (the forces involved in movement) during walking strides. For this he studied adult giraffes at three zoological parks in the UK. 

However, due to the close proximity of fencing and buildings, it is not practical to study fast speeds in a zoo setting. 

A setting such as the Willem Pretorius Nature Reserve, near Ventersburg in the Free State, Kwaggafontein Nature Reserve, near Colesberg in the Karoo, and the Woodland Hills Wildlife Estate in Bloemfontein are all ideal for studying crucial aspects such as “faster than walking” speeds and gaits to measure key parameters (such as stride length, step frequency and stride duration). These studies are important to understand how giraffe form and function are adapted to their full range of locomotor behaviours. It also helps to comprehend the limits on athletic capacity in giraffes and how these compare to other animals. 

Drones open up unique opportunities for studying giraffes

The increasing availability of unmanned aerial vehicles (UAVs)/drones opens up unique opportunities for studying locomotion in animals like giraffes. Cameras mounted onto remotely controlled UAVs are a straightforward way to obtain high-quality video footage of giraffes while they run at different speeds.

“Using two UAVs, we have collected high definition slow motion video footage of galloping giraffes from three locations in the Free State. We have also collected detailed information about the terrain that the giraffes walked and ran across. From this we have created 3D maps of the ground. These maps will be used to examine the preferred terrain types for giraffes, and to see how different terrains affect their locomotion and energy use,” said Dr Deacon.

“The raw data (videos) will be digitised to obtain the stride parameters and limb angles of the animals. Later this will be combined with anatomical data and an estimation of limb forces to estimate the power output of the limbs and how that changes between different terrains,” said Dr Basu.
