|Title:||Design of Reference Populations for Genomic Selection in Crossbreeding Programs||Contributor(s):||van Grevenhof, Isle E M (author); Van Der Werf, Julius H (author)||Publication Date:||2014||Handle Link:||https://hdl.handle.net/1959.11/18733||Abstract:||In crossbreeding (CB) programs, genomic selection offers the opportunity to make efficient use of information on crossbreds in the selection of purebred candidates (PB). In a deterministic simulation study, we evaluated the use of various proportions of crossbred animals in a reference population for genomic selection of purebred animals used in a crossbreeding program. When the breeding objective is to improve crossbred performance, the optimal proportion of CB in the reference population is 100% unless the correlation between purebred and crossbred performance is high. However, the value of replacing purebred animals with crossbred animals in the reference population is generally small unless the correlation between purebred and crossbred performance is relatively low (< 0.7) or when purebred performance is not considered in the breeding objective.||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) (Genetic Improvement Programs: Breeding objectives, economics of selection schemes, and advances in selection theory), p. 1-3||Publisher:||American Society of Animal Science||Place of Publication:||Champaign, United States of America||Field of Research (FOR):||070201 Animal Breeding||Socio-Economic Outcome Codes:||830308 Pigs||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Other Links:||https://asas.org/docs/default-source/wcgalp-proceedings-oral/015_paper_9407_manuscript_1593_0.pdf||Statistics to Oct 2018:||Visitors: 154
