Feet and leg/locomotor issues represent a primary reason for sow removal from U.S. breeding herds. A shift from gestation stalls (GS) to group-sow housing (GSH) is occurring the U.S. swine industry, emphasizing the importance of structural soundness

Computer vision systems (CVS) have many applications in livestock, for example, they allow measuring traits of interest without the need for directly handling the animals, avoiding unnecessary animal stress. The objective in the current study was to

Combining purebreed and crossbreed information is beneficial for genetic evaluation of some livestock species. Genetic evaluations can use relationships based on genomic information, relying on allele frequencies that are breed specific. Single-step

Background The quantitative genetics theory argues that inbreeding depression and heterosis are founded on the existence of directional dominance. However, most procedures for genomic selection that have included dominance effects assumed prior symme
