The role of reference populations in genetic evaluation for Australian beef cattle.
Genomic information is playing an increasingly important role in genetic evaluation for beef cattle breeders. As genotyping becomes more common, it is the quality and quantity of phenotypes for economically important traits which determines the effectiveness of these evaluations.
In this webinar recording, join Dr Matt Wolcott (Animal Genetics Breeding Unit Scientist, University of New England) when he examines the role of genomic information in modern genetic evaluation and discusses how breeds and breeders can identify traits for which intensive recording strategies will yield the greatest benefit.
Matt also presents a case study which examines the establishment of an effective reference population in a commercial Australian Brahman stud herd, and the contributions this work made to EBV accuracy at the breed level.
