Zearalenone (ZEN) and sterigmatocystin (STC) concentrations in the dietary straw, and ZEN, α-Zearalenol (α-ZOL), and β-Zearalenol (β-ZOL) concentrations in urine samples of cattle derived from each experimental group collected on the same day.
| Experimental Group | Straw (mg/kg) | Urine Samples (Mean ± SEM; pg/mg Creatinine) | ||||
|---|---|---|---|---|---|---|
| ZEN | STC | ZEN (n = 6) | α-ZOL (n = 6) | β-ZOL (n = 6) | STC (n = 6) | |
| Herd 1 | 7.6 | 0.24 | 3702 ± 747 | 859 ± 178 | 5503 ± 1130 | 569 ± 111 |
| (−42 days) * | 7.5 | 0.17 | 2444 ± 394 | 759 ± 148 | 5496 ± 1197 | 209 ± 22 |
| Herd 1N | ND | 0.04 | 63 ± 12 | 20 ± 3 | 119 ± 18 | 33 ± 8 |
| Herd 2 | 0.2 | <0.01 | 50 ± 8 | ND | 82 ± 27 | 47 ± 19 |
| (−34 days) ** | 0.2 | 0.03 | 68 ± 10 | 21 ± 9 | 215 ± 51 | 147 ± 39 |
These concentrations in straw and urine samples have been partially reported previously (Hasunuma et al., 2012 and Fushimi et al., 2014a, b). *: Straw and urine samples collected 42 days before the sampling for metabolomics in Herd 1. **: Straw and urine samples collected 34 days before the sampling for metabolomics in Herd 2.
