|Title:||Genomic Evaluations in the Australian Sheep Industry||Contributor(s):||Swan, Andrew (author); Brown, Daniel (author); Daetwyler, H D (author); Hayes, B J (author); Kelly, M (author); Moghaddar, Nasiroddin (author); Van Der Werf, Julius H (author)||Publication Date:||2014||Handle Link:||https://hdl.handle.net/1959.11/17373||Abstract:||The main benefit of genomic selection for Australian sheep is to increase the accuracy of hard to measure traits including carcass, adult wool and reproduction traits. A genotyped reference population has been established to measure these traits, and genomic predictions from this population show moderate accuracies, in the range 0.2 - 0.5. Genomically enhanced breeding values for traits in the current evaluation system have been delivered to breeders using the "blending" selection index method to combine genomic predictions with pedigree based estimated breeding values, and for carcass traits using the "single step" method. The goal for genomic evaluation is to move to single step analyses for all traits. One of the challenges is to accommodate breed and strain within breed structure, particularly for animals with unknown pedigree and no data. Marker information can be used to define genetic groups which correlate reasonably well with genetic groups defined from pedigree information.||Publication Type:||Conference Publication||Conference Name:||WCGALP 2014: 10th World Congress on Genetics Applied to Livestock Production, Vancouver, Canada, 17th - 22nd August, 2014||Conference Details:||WCGALP 2014: 10th World Congress on Genetics Applied to Livestock Production, Vancouver, Canada, 17th - 22nd August, 2014||Source of Publication:||Proceedings of the 10th World Congress on Genetics Applied to Livestock Production (WCGALP) (Species Breeding: Sheep and goats), p. 1-6||Publisher:||American Society of Animal Science||Place of Publication:||Champaign, United States of America||Field of Research (FOR):||070201 Animal Breeding
