Additionally, stage of lactation, parity, and BCS also affected the odds of false alerts, but no effect of GS was found. Cows in early lactation had the smallest odds of showing false alerts, as both those in mid and late lactation had greater odds of showing false alerts (P = 0.04). Primiparous cows had greater odds than multiparous cows (P = 0.04) to show false alerts and a tendency for BCS to affect false alerts was found. Thin cows had the smallest odds of showing false alerts in relation to average and moderately body conditioned cows (P = 0.06). Odds ratios for all potential impactors of false alerts are summarized in Table 3.
