A genome-wide association study reveals a quantitative trait locus for age at first calving in delta/notch-like EGF repeat containing on chromosome 2 in Japanese Black cattle.

Abstract excerpt

Age at first calving (AFC) is an important trait for achieving earlier reproductive performance in cattle. To identify quantitative trait loci for AFC in Japanese Black cattle, we conducted a genome-wide association study using 866 animals with extreme AFC values selected from a larger group of 52, 009 animals. We identified single nucleotide polymorphisms (SNPs) on bovine chromosome 2 that were associated with...
