Ingredient and nutrient compositions of the diet administered during the experimental period
| Ingredient (Kg/d) | |
|---|---|
| Grass silage | 18.50 |
| Barley | 1.00 |
| Beet pulp | 2.00 |
| Commercial concentrate 1 | 8.00 |
| Nutrient composition (%DM basis) | |
| DM (Kg/d) | 17.18 |
| NEL2 (Mcal/kg) | 1.55 |
| CP | 15.03 |
| NDF | 48.52 |
| NFC3 | 25.66 |
1 Contained 18% CP, 3% fat, 13% cellulose, 8000 UI/kg Vitamin A, 1200 UI/kg Vitamin D3, 15 mg/kg Vitamin E, 9.6 mg/kg CU2SO4.
2 Calculated according to NRC (2001). NEL was estimated based on a cows weighing 650 kg and average 21.8 kg dry matter intake per day.
3NFC calculated as 100 - [(NDF - NDFCP) + CP + ether extract + ash] (NRC, 2001).
