Overview

Genome-wide association studies identify QTLs for hematological traits in pigs, suggesting genetic factors influence blood health.

Key Points

  • This research aims to identify genetic loci associated with hematological traits in pigs at two ages.
  • Conducted genome-wide association studies on 24 hematological traits
  • Analyzed data from 1884 pigs at 25 days and 1615 pigs at 46 days
  • Collected samples from a crossbred pig cohort (Landrace × Yorkshire) × Duroc
  • Identified 57 QTLs associated with complete blood count traits
  • Found 11 lead SNPs linked to multiple hematological traits
  • 30 QTLs overlapped with previously identified QTLs in different pig breeds
