Zane Botha has won a Varsity Cup title as captain of Tuks, two Varsity hostel titles as coach of Vishuis, and now he would like to add a third trophy to his belt as head coach of the UFS Young Guns.

Zane guided House Vishuis to the national crown in 2017 and 2018 and was promoted to coach of the university’s U20 team playing in the Varsity Cup, known as the Young Guns.

Botha lifted the Varsity Cup trophy as the skipper of Tuks in 2012.

“To achieve success in a third Varsity competition would be quite special and is definitely a goal that I look forward to achieving while I work with young people,” Zane said.

The format of the Rugby Varsity Cup competition has changed and will now coincide with the competition for senior players. Both the seniors and the younger players will face the same opponents on the same day. The Young Guns are scheduled to play eight fixtures before the knockout stages, in contrast to earlier years when they only played twice against two opponents before the semi-finals.

In 2018 the UFS U20 team, who previously won the competition in 2014, won all four of their matches against the Ixias and the Pukke before they lost to Tuks in the semi-final.

According to Zane, this format provides the players with more playing opportunities, but at the same time it can also place their depth under pressure when they’re facing injuries, which he aims to limit.

He further explained that he is pleased to have had buy-in in the first round of matches, as it provided him with an extra week’s preparation.

Research is being done at the University of the Free State (UFS) to analyse and synthetically imitate the unique milk of various wildlife species. This research is not only of scientific value, but also serves the conservation of South Africa’s wildlife species. At the forefront of this research is Prof Garry Osthoff from the Department of Microbial, Biochemical and Food Biotechnology.

Orphaned rhino calf pulled through with surrogate milk

“There is still a lot of research to be done. Naturally the research is of scientific importance, but with surrogate milk having the same composition as the mother’s milk of a specific species, orphaned calves or cubs of that species could be pulled through during a difficult time of weaning. Bearing in mind that exotic animals fetch thousands and even millions of rands at auctions, it goes without saying a game farmer will do everything possible to provide only the best nourishment to such an orphaned animal. In such a case, synthetically-manufactured milk would be the right choice,” says Prof Osthoff.

The fruits of his research were recently demonstrated in Germany when a rhino calf was left orphaned in the Leipzig Zoo. Prof Osthoff’s article: “Milk composition of a free-ranging white rhinoceros during late lactation” was used as a directive for applying surrogate milk for horse foals (which is already commercially available), since the composition of horse and rhino milk largely corresponds. The surrogate milk was used with great success and the rhino calf is flourishing. He mentions that such an orphan is often given the wrong nourishment with the best intentions, resulting in the starvation of the animal despite the amount of cow’s milk it devours.

Milk formula for baby elephants in the pipeline
With baby elephants left orphaned due to the increase in elephant poaching for their ivory, several attempts have been made to create a milk formula in order to feed these elephants. To date, many elephants have died in captivity from side effects such as diarrhoea as a result of the surrogate formula which they were fed.

Prof Osthoff recently received a consignment of frozen milk which he, together with researchers from Zimbabwe, will use to work on a milk formula for elephants. They are studying the milk in a full lactation period of two years. During lactation, the composition of the milk changes to such an extent that a single surrogate formula will not be sufficient. Four different formulas should probably be designed.

Prof Osthoff says that of the different species he has researched, elephants are the most interesting and deviate most from the known species.

Although his research to develop surrogate milk is adding much value to the wildlife industry, and although he finds this part of his work very exciting, his research focus is on food science and nutrition. “What is currently authentic in milk research is the study of the fat globules with content, the structure and composition of the casein micelle, and the prebiotic sugars. The knowledge which is gained helps to improve the processing, development of new food products, and development of food products for health purposes,” says Prof Osthoff.
