Figure 1

Average analyte concentrations ± standard error (SEM) of the mean in A) urine and B) feces of sows from four defined reproductive stages. Concentrations of hormones and phytoestrogens (LC/MS-MS results) are shown on the left y-axis, while the corresponding EEQ (YES assay results) is shown on the right y-axis. For estrogens, androgens, and phytoestrogens, the concentrations shown here represent the sum of all relevant species detected, including both free and conjugated forms of estrogens and androgens. All concentrations are in parts-per-billion (μg/l urine and μg/kg dry mass feces).
