Abstract: | The presence of genotype by environment interactions (GxE) affects the decisions made by livestock producers when selecting breeding animals. Studies have traditionally focussed on selection criteria, and on a single trait basis, with most finding little evidence of GxE. This study demonstrates that substantial GxE occurs for the beef cattle breeding objective. When the length of the feeding period or cow feed price varies, or they vary in combination, the correlations between sire rankings decrease. Ignoring the occurrence of this GxE in selection risks compromising commercial production system profitability. | Publication Type: | Conference Publication | Conference Name: | 11th World Congress on Genetics Applied to Livestock Production | Conference Details: | World Congress on Genetics Applied to Livestock Production, Auckland, New Zealand, 10-16 February | Source of Publication: | Proceedings of the World Congress on Genetics Applied to Livestock Production, v.11, p. 1-5 | Field of Research (FOR): | 070201 Animal Breeding | Socio-Economic Outcome Codes: | 830301 Beef Cattle | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication | Other Links: | http://www.wcgalp.org/proceedings/2018 |
