Prof Robert Bragg recently participated in a live panel discussion with leaders from the food and beverage sector, debating the challenges facing the industry and sharing their lessons and solutions.

Prof Robert Bragg from the Department of Microbiology and Biochemistry at the University of the Free State formed part of a live panel discussion with leaders from the food and beverage sector, debating the challenges facing the industry and sharing their lessons and solutions.

The discussion, part of a week-long virtual event (19-23 April), was attended by more than 1 300 attendees representing 500 food manufacturers, retailers, ingredient companies, and laboratories from 83 countries.

The magazine, New Food, coordinated the initiative that focused on food integrity. Speaking with Prof Bragg at the session that centred around animal welfare, zoonotic disease, and antibiotics, were Catherine McLaughlin, Chair, Responsible Use of Medicines in Agriculture (RUMA); Vicky Bond, UK Managing Director, The Humane League; and Daniela Battaglia, Livestock Development Officer, Food and Agriculture Organization of the United Nations (FAO).

The rise of antibiotic resistance

James Russell, President of the British Veterinary Association (BVA), was the moderator of the discussion that also touched on the issues surrounding animal welfare; how animal welfare can impact meat quality; avoiding future zoonotic disease; the rise of antibiotic resistance; ethical considerations to be mindful of; and the use of pesticides and safety considerations.

Prof Bragg specifically talked about antibiotic resistance. “Mankind has major problems with antibiotics,” he said. 

He asked if animal agriculture can be sustained without the use of antibiotics and stated that it was necessary to look at alternatives. Possible solutions he suggested include improved vaccines, bacteriophages, and phage enzymes. He, however, believes that biosecurity will be the most effective alternative. 

Living in a post-antibiotic area

Disinfectants are one of the biosecurity measures taken to minimise the risk of infectious diseases. “But it is important to be aware of the fact that as resistance to antibiotics increases the resistance to disinfectants also increases,” said Prof Bragg. 

He continued: “An increase in the use of disinfectants increases the resistance to disinfectants. This is also evident in humans, especially now during the COVID-19 pandemic. Much of these disinfectants are also of poor quality,” he said. 

According to Prof Bragg, we are living in a post-antibiotic era. “Although food standards are higher in developed countries such as in Europe – where people can pay more for poultry that were fed diets with reduced antibiotics, it is important to keep in mind that people cannot pay the same for poultry in developing countries. These countries often import poultry from countries where the food standards are not that high and where birds were treated to diets containing more antibiotics. A large supplier of poultry in Africa is small-scale farmers, who also feed their birds food containing higher levels of antibiotics.” 

“We need to look at the antibiotic problem as a global problem; a concern that will be with us for a while,” said Prof Bragg.

One solution provided by the group was for mankind to reduce its meat intake and moving to a more plant-based diet. This will have a significant effect on animal welfare as well as reducing the demand for antibiotics.

It is better for Super Rugby teams not to have the ball, which also leads to reduced overall playing time in matches.

This observation is from a study by the University of the Free State on the difference between winning and losing teams. Statistics between 2011 and 2015 show that Super Rugby winning teams kick more and their defence is better.

These statistics were applied by Riaan Schoeman, lecturer in Exercise and Sport Sciences, Prof Derik Coetzee, Head of Department: Exercise and Sport Sciences, and Prof Robert Schall, Department of Mathematics and Actuarial Sciences. The purpose of the study, Changes in match variables for winning and losing teams in Super Rugby from 2011 to 2015, was to observe changes. Data on 30 games (four from each team) per season, supplied by the Cheetahs via Verusco TryMaker Pro, were used.

About two minutes less action
“We found that the playing time has decreased. This is the time the ball is in play during 80 minutes,” says Schoeman. In 2011, the average playing time was 34.12 minutes and in 2015 it was 31.95.

“The winning team has less possession of the ball and doesn’t want it. They play more conservatively. They dominate with kicks and then they play,” says Prof Coetzee, who was the conditioning coach for the Springboks in 2007 when they won the World Cup.

Lineouts also more about kicking
As a result, the number of line-outs also increased (from 0.31 per minute in 2011 to 0.34 in 2015) and the winning teams are better in this regard.

“The winning team has less possession of the ball
and doesn’t want it. They play a more conservative
game. They dominate with kicks and then they play.”

Schoeman believes that rule changes could also have contributed to reduced playing time, since something like scrum work nowadays causes more problems. “When a scrum falls, the time thereafter is not playing time.”

According to Prof Coetzee, rucks and mauls have also increased, (rucks from 2.08 per minute in 2011 to 2.16 in 2015 and mauls from 0.07 per minute in 2011 to 0.10 in 2015). “The teams that win, dominate these areas,” he says.
