12 Beef Genomics Programme

13 BGP: intention To ensure accurate measurement of phenotypes closely associated with quality of beef produced in Southern Africa To combine the phenotypic data with genomic data to further enhance breeding values of the Southern African beef herd To use the enhanced breeding information to increase the competitiveness of the industry

14 Participating institutions Agricultural Research Council accredited testing stations Universities: Pretoria Fort Hare Free State Stellenbosch Breed societies (15 breeds) Service providers (Stud Book, Livestock Registering Federation)

15 Participating breeds 2015/16 Afrikaner Beefmaster Bonsmara (SA and Namibia) Boran Brahman (SA and Namibia) Charolais Drakensberger Hereford Limousin Santa Gertrudis Simbra Simmentaler 2016/17 Brangus Nguni Tuli

16 Programme funding The Technology Innovation Agency (TIA) of South Africa funded the programme for R for three years starting in April /16: R /17: R /18: R The Programme is substantially co-funded by industry 2015/16: > R18 m 5.36X initial estimate

17 BGP outcome: 1 st 3 years Useful data for research Data to be provided by the Breed Society to their service provider of choice for the development of the EBVs/GEBVs and economical indices as required by the Society

18 Programme progress

19 Teamwork and collaboration Between industry groups Between breeds within groups Leadership established within breeds Amongst project committee members Amongst research committee members

20 Research objective: Databank Central databank established Access to breed data by nominated society representative Further value-addition to data by chosen service provider

21 Research objective: WGS 39 highly influential animals sequenced 2-4 animals per participating breed For some breeds- first WGS undertaken

22 Trait measurements Stud Book and LRF different BGP approaches Co-funded by TIA and industry Measurements include: matings births birth, weaning, yearling, mature weights feed intake meat quality scrotal measurements fertility

23 Conclusion

24 Implementation year Collection of trait records exceeded expectation Genotyping exceeded targets Research programme is on track Principles and protocols are in place Good collaboration amongst diverse team members Full effect of the drought to be realised and mitigated
