Uterine and vaginal swabs from cows Metagenome
Vaginal samples were collected from cows (n = 100) two days before artificial insemination. Uterine samples were collected immediately after vaginal swabbing using a double-guarded swab. This cohort had an 88% pregnancy success rate, leaving only 12 non-pregnant animals available for inclusion as open cows. Metagenomic DNA was extracted from uterine and vaginal swabs and sequenced.
