Table 1.
Simple linear regression parameters estimated from measured (dependent variable) over actual (independent variable) starch added on different organic matrices.

| Tifton 85 hay | 0.955 ± 0.363 | 1.001 ± 0.008 | 0.81 | 0.999 | 0.852 |
| Abomasal digesta | 5.784 ± 0.775 | 1.008 ± 0.017 | 1.73 | 0.996 | 0.675 |
| Feces | 2.113 ± 0.521 | 1.000 ± 0.012 | 1.16 | 0.998 | 0.991 |
a
H0: β1 = 1 vs. Ha: β1 ≠ 1. Slope coefficient is related to the recovery rate of added starch (β1 = 1 means complete recovery).
