Carel Teseling

Carel is currently the Technical Services Manager of the Australian Wagyu Association and will be responsible for the provision of technical information to the Wagyu Association and it's members.

From 2001 to 2015 Carel was the Breed Development and Innovation Manager of Angus Australia. During this period he was responsible for the development and implementation of EBVs for Net Feed Intake, Docility and structural traits for Angus. He was also instrumental in setting up the Angus Young Sires Program that paved the way for a dramatic increase in the use of Australian bred Angus bulls. The discovery of several genetic conditions required him to, in conjunction with Brian Kinghorn and ABRI, develop and implement GeneProb for Angus, which was subsequently also implemented for several other breeds. This software calculates, based on the test results of a limited number of animals, the carrier probability of all animals in a population. Carel was also responsible for the implementation of EBVs that incorporate genomic information from several service providers.

From 1991 to 2000 Carel was the Regional Manager of the Agricultural Research Council in the Eastern Cape and responsible for all facets of beef cattle performance recording in the region. During this period he also conducted consultation visits, workshops and field days to educate seedstock breeders, representing all the major beef breeds, on genetic improvement and production related topics. He was also responsible for the management of the bull testing centre in Queenstown where young bulls were tested for feed efficiency.
