Abstract excerpt
Genomic selection for greater HS tolerance (TOL) may enhance swine welfare under heat stress (HS) conditions. However, genomic selection for TOL based on variability in performance traits across environmental gradients tends to be genetically associated with reduced productivity. Therefore, the study objective was to biologically characterize genomic selection for TOL based on the rate of vaginal temperature (TV)...
