Auction catalogue as a guideline for selection
The importance of breeding objectives for a commercial herd was discussed during the Afrikaner Bushveld Study Group’s ‘School of Beef’, hosted at the recent Thabazimbi Show. Breeding objectives should be tailor-made for each herd, depending on the environment, breed type, market requirements and production system. Selecting specific breeding material to improve your herd can be a challenging process. The lack of specific breeding goals for your herd could result in the aimless selection of a breeding bull, and this can place the genetic potential of your cowherd at a disadvantage. The interpretation of the auction catalogue, especially on traits of economic importance such as fertility and growth, are essential tools for the commercial beef producer. Fertility and growth will enhance the optimum number and weight of weaner calves, in order to improve profitability.
IMPORTANCE OF THE BREEDING BULL
Best Linear Unbiased Prediction (BLUP) information on the catalogue is based on performance data and is an unbiased, objective method to identify superior genetics. The physical appearance of a breeding bull is however just as important to ensure functional efficiency.
Although functional efficiency is a subjective inspection by breed inspectors, it is important to note that the process is based on minimum breed standards, which would also ensure functionality. Traits (good or bad) are heritable and the purpose of selection is to ensure superior genetics and improvement. The heritability of growth traits is fairly high and an inferior bull may influence the performance of a herd negatively. The wrong bull for your herd could end up breeding calves with lower weaning weights.

New farmers' seedling pitfalls
Inexperienced farmers may be tempted to grow seedlings from seed themselves, but they have much to gain by trusting a seedling grower at a nursery to perform this task for them instead
South African avocado production: a success story
Avocado production in South Africa has expanded markedly since the industry's humble beginnings over 80 years ago. From a small grove planted in 1938 in what was then Nelspruit, the industry has blossomed to seven million trees planted on 20 000ha. Dr Guy Witney, project manager at Great Brak Avos, spoke to Annelie Coleman about the country's avocado production.
Unlocking value through livestock exports
Exporting livestock might sound like a daunting business that's better left for big companies, but Gerrie Ferreira, who farms near Oudtshoorn in the Western Cape, has been doing it successfully for almost 30 years, sometimes in partnership with other breeders. He spoke to Glenneis Kriel about the huge potential this market holds, and offers some advice for farmers who are contemplating going this route.
An agribusiness's dedication to community upliftment
For agribusiness NWK, located in Lichtenburg, North West, corporate social investment is an important part of creating a positive influence alongside financial returns.

Empowering dreams, transforming lives
Since its launch in 2013, the Agri's Got Talent competition has revolutionised the lives of many farmworkers by unlocking their hidden talents and fostering a culture of empowerment. Glenneis Kriel spoke to various finalists about how the contest has changed their lives.
Foreign investment: agriculture maintains its appeal
South Africa remains a popular destination for foreign investors, despite an often negative outlook from its citizens. It is a gateway to Africa, and with its counterseasonal production to the Northern Hemisphere and favourable weather, local agriculture is especially well placed to attract foreign interest, bringing with it hope for rural communities
The real value and message of COP29 for SA agriculture
While the 2024 Conference of the Parties may have disappointed those who hoped for real progress, it's more important for South African agriculture to highlight its role in carbon mitigation
