Characteristics of CON and EFC after steam flaking to a bulk density of 360 g/L (at 6 t/h) or 390 g/L (at 9 t/h), respectively, from daily grain samples
| Item | CON | EFC | SEM | P-value |
|---|---|---|---|---|
| DM, % | 78.8 | 78.9 | 0.70 | 0.55 |
| Starch availability, %1 | 51.3 | 52.1 | 0.30 | 0.08 |
| dgw, µm2 | 4,413 | 4,292 | 24 | <0.01 |
| Sgw3 | 1.50 | 1.50 | 0.017 | 0.99 |
1Measured using the refractive index method (Sindt et al., 2006b) immediately after flaking.
2Mean geometric particle size: measured by placing flaked grains (200 g) in a set of sieves with descending screen sizes in a Ro-Tap orbital shaker (RX-30; W. S. Tyler, Mentor, OH), and weighing each fraction following a 5-min rotary tapping cycle. Calculated using equations described by Pfost and Headley (1976).
3Standard deviation of particle size: calculated using equations described by Pfost and Headley (1976) following the procedure described above2.
