Genomic selection now also used in Topigs dam lines
Topigs has started to apply genomic selection in dam line breeding. This means that both breeding sows and boars are now partly selected on the basis of genomic selection.
This step follows the introduction last year of genomic selection for the breeding of Topigs finisher boars. In the Nador concept genomic selection is used to select for boars that are less susceptible to boar taint.
The use of genomic selection information in dam line breeding allows more and faster genetic progress to be achieved in areas such as litter size, birth weight, vitality and mothering abilities. Faster progress can also be made in the area of genetic improvement for finisher and slaughter traits in the dam lines.
Genomic selection boosts genetic progress by 30%. Topigs can also play its trump card: phenotypic information from almost 25 million pigs. These data enhance the possibilities of genomic selection thanks to a better linking of genotypic and phenotypic information.
With genomic selection, a direct picture of the genetic disposition for a certain trait can be obtained. In particular, faster genetic progress can now be achieved for those traits that are only measurable late in a pig’s life, are sex-linked or have a low heritability. Genomic selection also makes it possible to work with specific breeding goals.
