Topigs Norsvin speeds up with genomics

July 27, 2015

The current setup of genomics makes use of accurate relations between animals and will increase genetic gain across all traits by 30% or more. With accurate phenotypes, enough animals to select from, a short generation interval, and a high accuracy of breeding values, we can make maximum use of genomic selection.

With the arrival of abundant genomic information, we can better capture heterosis and genetic dominance in lines and crossbreds. With this new source of information, we will not only improve our understanding of the genetic architecture of complex traits, but we will also be able to optimise matings, even in purebred populations, to find the service sire that produces the most heterozygote markers given the specific sow. Topigs Norsvin is heavily investing in understanding heterosis and dominance so that it can better predict crossbred performance.
