Genome-Wide Association Study of Age at First Calving in U.S. Holstein Cows.

International journal of molecular sciences - 12 Apr 2023

Prakapenka Dzianis, Liang Zuoxiang, Da Yang

Abstract excerpt

A genome-wide association study (GWAS) of age at first calving (AFC) using 813,114 first lactation Holstein cows and 75,524 SNPs identified 2063 additive effects and 29 dominance effects with p-values < 10-8. Three chromosomes had highly significant additive effects in the regions of 7.86-8.12 Mb of Chr15, 27.07-27.48 Mb and 31.25-32.11 Mb of Chr19, and 26.92-32.60 Mb of Chr23. Two of the genes in those regions...
