Table 3.
Effects of partially replacing maize silage and barley straw in a mixed diet (CON) by crude olive cake (COC) on microbial protein synthesis (in solid and liquid digesta) and on its efficiency in Rusitec fermenters (n = 4).
| Item | Diet | SEM | p-Value | |
|---|---|---|---|---|
| CON | COC | |||
| Microbial protein synthesis (mg N/day) | ||||
| Solid phase | 199 | 171 | 7.2 | 0.05 |
| Liquid phase | 107 | 119 | 2.6 | 0.03 |
| Total | 306 | 290 | 6.3 | 0.15 |
| Efficiency of microbial growth 1 | 32.9 | 32.6 | 0.81 | 0.79 |
1 Expressed as mg microbial N per g OM apparently fermented; OM apparently fermented was estimated from VFA production according to Demeyer [38].
