Figure 4From: Evaluation of two dairy herd reproductive performance indicators that are adjusted for voluntary waiting periodReceiver operating characteristic curves from the logistic regression model where the different reproductive performance indicators predicted the outcome of reproductive physiology. CI = Calving interval, days. FI = fertility index. IC100 = proportion of pregnant cows 100 days after calving. NotIC200 = proportion of non pregnant cows 200 days after calving. PV30 = proportion of pregnant cows 30 days after the herd VWP. IV30 = proportion of inseminated cows 30 days after the herd VWP.Back to article page
