| Round | 4x4 | 0.25 | 85 | 0.21 |
| Round | 5x4 | 0.35 | 85 | 0.30 |
| Round | 5x6 | 0.50 | 85 | 0.43 |
| Square | 8x3x3 | 0.30 | 85 | 0.26 |
| Square | 8x4x3 | 0.60 | 85 | 0.51 |
| Square | 8x4x4 | 0.75 | 85 | 0.64 |
| Small Squares | 0.025 | 85 | 0.02 |
Silage
| Bale shape | Bale size | Weight (as fed, t) | Dry Matter (%) | Dry weight (t DM) |
| Round | 4x4 | 0.60 | 40 | 0.24 |
| Round | 5x4 | 0.75 | 40 | 0.30 |
| 1 cubic metre (wilted) | 0.58 | 30 | 0.17 | |
