| Dry matter | 903 | 903 | 902 | 905 |
| Organic matter | 945 | 957 | 969 | 970 |
| Crude protein | 145 | 145 | 145 | 145 |
| Neutral detergent fiber | 245 | 242 | 245 | 250 |
| Acid detergent fiber | 100 | 107 | 111 | 126 |
| Ether extract | 44.8 | 46.2 | 46.3 | 52.2 |

1 Calculated from analyzed composition of individual feed ingredients. All chemical fractions are expressed as g/kg dry matter, except dry matter (g/kg fresh matter). Non-structural carbohydrates were calculated as the difference between organic matter and the sum of crude protein, neutral detergent fiber and ether extract.
