Collaborative project: Genomic indicators for boar taint, fertility and robustness in Landrace- and Large White populations. Subproject 1 (G-I-FER)
Project
Project code: 2817904115
Contract period: 01.09.2016
- 31.08.2019
Budget: 666,653 Euro
Purpose of research: Experimental development
"The aim of the project was the genetic improvement of boar taint in porcine dam lines under consideration of fertility and robustness.
Based on quantitative genetic analyses the genetic foundation of boar taint as well as maternal and paternal fertility was estimated. The genetic correlations of these trait complexes have suggested that negative consequences on economically relevant fertility traits due to selection against boar taint can hardly be expected. Using GWAS QTL-regions have been identified that are involved in the regulation of boar taint or fertility hormones. These QTL were mainly population specific. Pleiotropic effects for fertility, robustness, and boar taint have not been identified. Conclusion: Reduction of odorous carcasses in dam lines by genomic selection is possible without specific attention of fertility-regulating genes."
