Topigs has started to use genomic selection in dam line breeding, expanding the process the company introduced for its finisher boars at the end of 2011.

The use of genomic selection information in dam line breeding allows for more and faster genetic progress to be achieved in areas such as litter size, birth weight, vitality and mothering abilities, according to the company. 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 percent, and gives Topigs 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.
