The giraffe research programme and infrastructure facility at Amanzi Private Game Reserve marks the next phase in a research journey that has already placed the UFS at the forefront of giraffe science.

The University of the Free State (UFS) is taking wildlife research to new heights. On Wednesday 29 October 2025, the university will officially launch the giraffe research programme and infrastructure facility at the Amanzi Private Game Reserve near Brandfort – a first-of-its-kind in the world, dedicated to advancing local and international scientific collaboration in the study and conservation of giraffes.

The launch marks the next phase in a research journey that has already placed the UFS at the forefront of giraffe science. Over the past decade, a team of researchers, led by Prof Francois Deacon from the Department of Animal Science, has made significant contributions to understanding giraffe behaviour, physiology, and ecology. Building on pioneering work in reproductive technologies, endocrinology, anatomy, and disease, the new infrastructure combines on-site research laboratories with spacious, stress-free habitats. In this hands-on environment, veterinarians, scientists, and students can work closely with giraffes while promoting their welfare and supporting both local and international research projects.

Over the past seven years, his team has conducted 254 successful sedations and captures, carefully building the expertise needed for the next delicate step: the first embryo transfer in wild giraffes.

“This dedicated research facility will provide a safe and controlled environment where the world’s first giraffe embryo can develop and grow, and where we can collaborate to produce the science needed to turn the extinction of the giraffe around,” he explains. “The general public may not see the results immediately, but 20 years from now, what we are doing today will be vital in creating a biobank of viable giraffe embryos and calves that can be used in surrogate animals, supporting sustainable conservation practices for future generations.”

This programme will allow researchers to expand their understanding of the world’s tallest land mammal in ways that were not possible before. “From conducting sedation and sample collection to pioneering reproductive techniques such as semen preservation and embryo transfer, the facility provides an environment where we can study, among others, giraffe genetics, reproductive biology, and physiology; knowledge that is important for their conservation and survival,” says Prof Deacon. 

About 12 departments at the UFS are already involved in the research project in one way or another. This includes from the Department of Animal Science to the Departments of Zoology and Entomology, as well as Chemistry and even Information and Communication and Technology Services, which contributes to 3D-modelling, software, and monitoring of the animals. 

The project also offers opportunities for collaboration with conservation organisations and universities worldwide, positioning the UFS as a leading hub for giraffe and large-mammal research in Africa. Current partners who share Prof Deacon’s vision for giraffe conservation on the African continent include Save the Giraffes (a US-based NGO), Absolute Genetics, Ramsem, and the Kroonstad Animal Hospital.

Despite their towering presence on the African continent, giraffes are quietly disappearing. The International Union for Conservation of Nature (IUCN) lists them as Vulnerable, with populations declining by more than 40% over the past three decades. Today, fewer than 100 000 remain in the wild – a sobering reminder that their future is far from secure and that research excellence like this is key to ensure their survival.

“We have all the technology and all the expertise to make a change. Now is the time to bring about this change to secure the future of giraffes on this continent,” Prof Deacon concludes, emphasising the UFS’ commitment to sustainability, care, and conservation.

Childhood obesity should be curbed early

Serious intervention by parents is required to deal
with childhood obesity. Prof Louise van den Berg and

about the prevalence of obesity in six-year-olds in

If your child is overweight when they start school at the age of six, unless you do something about it at that point, the indications are they are going to be overweight teenagers and obese adults. This is according to University of the Free State’s Prof Louise van den Berg.

Evidence has shown that overweight children and teenagers have a greater risk of developing lifestyle diseases such as type 2 diabetes, hypertension and cardiovascular disease later in life, and dying prematurely.

Obesity is a global pandemic rapidly spreading among adults and children, in developed and developing countries alike.

Dr Van den Berg worked with Keagan Di Ascenzo, Maryke Ferreira, Monja-Marie Kok, Anneke Lauwrens, all PhD students with the Department of Nutrition and Dietetics, to conduct the study. Their research found that children who are overweight by the time they turn six should be screened for weight problems.

Why six-year-olds?
Children who are overweight between the ages of two and five are five times more likely to be overweight when they are 12. There are two periods in a normal life cycle when the body makes new fat cells. The first is in the uterus and the second is around the age of six. The second phase lasts from the age of six to puberty.

The study assessed the prevalence of obesity in six-year-olds as part of a campaign in South Africa to raise awareness of the problem among parents and educators.

A total of 99 children were chosen from seven schools in Mangaung, the capital city of Free State. The schools were chosen from quintile four and five schools, which when measured by their own resources and economic circumstances, are well resourced and serve largely middle-class and wealthy communities.

The children’s weight, height and waist circumference were measured and used to calculate a body mass index score and waist-to-height ratio. Both these figures are good predictors for future lifestyle disease risks such as type 2 diabetes, hypertension and cardiovascular disease. A person with a good waist-to-height ratio can wrap a piece of string equal to their height around their waist at least twice.

When the children had a higher body mass index, they also had an increased waist to height ratio. The study found one in four children from the schools surveyed were overweight when they started primary school.

Nipping the fat in the bud
Although there are many factors that play a role in preventing childhood obesity, parents’ perceptions of their children’s weight play an important role. A recent study found that more than 50% of parents underestimate the weight of their obese children. These parents remain unaware of the risks their children face and are not motivated to take any action.

At least half of the parents whose children are overweight struggle to recognise their children’s weight problems fearing that they will be labelled or stigmatised. By the time they turn six overweight children should be referred to dieticians and nutritionists who are qualified to guide their parents in getting them to eat well and be more physically active at pre-primary and primary school.

The high prevalence of weight problems among six-year-olds found in this study is an urgent call to healthcare professionals to step up and empower parents, educators and children with the necessary skills for healthy dietary practices and adequate physical activity.
