Reproductive productivity depend on a complex set of characteristics. The number of piglets
at birth (Total number born, Litter size, TNB) and the number of alive piglets at birth (Total …

Background Use of whole-genome sequence data (WGS) is expected to improve
identification of quantitative trait loci (QTL). However, this requires imputation to WGS, often …

Background More teats are necessary for sows to nurse larger litters to provide immunity
and nutrient for piglets prior to weaning. Previous studies have reported the strong effect of …

Pedigrees and dense marker panels have been used to predict the genetic merit of
individuals in plant and animal breeding, accounting primarily for the contribution of additive …

Background Heterosis has been suggested to be caused by dominance effects. We
performed a joint genome-wide association analysis (GWAS) using data from multi-breed …

Background Reproductive traits such as number of stillborn piglets (SB) and number of teats
(NT) have been evaluated in many genome-wide association studies (GWAS). Most of these …

Significance testing for genome‐wide association study (GWAS) with increasing SNP
density up to whole‐genome sequence data (WGS) is not straightforward, because of strong …

Background Genomic selection using single nucleotide polymorphism (SNP) markers has
been widely used for genetic improvement of livestock, but most current methods of genomic …

Background The number of teats in pigs is related to a sow's ability to rear piglets to weaning
age. Several studies have identified genes and genomic regions that affect teat number in …

The number of vertebrae, especially thoracic vertebrae, is an important economic trait that
may influence carcass length and meat production in animals. However, the genetic basis of …
