| Wheat bran | 5.0 |
| DDGS | 10.0 |
| Extruded soybean | 4.9 |
| Extruded corn | 5.0 |
| Cottonseed meal | 3.0 |

| Nutrient composition, %2 | |
| DM | 89.39 |
| CP | 21.18 |
| DE, MJ/kg3 | 12.62 |
| EE | 2.03 |

DDGS = distillers dried grains with soluble; DM = dry matter; CP = crude protein; DE = digestible energy; EE = ether extract.
The calf premix provided the following per kg of diets: VA 15,000 IU, VD 5,000 IU, VE 50 mg, VK3 4 mg, VB1 8 mg, VB2 7.2 mg, VB5 80 mg, VB6 8 mg, VB12 0.04 mg, biotin 0.60 mg, folic acid 4.0 mg, nicotinic acid 20 mg, Fe (as ferrous sulfate) 90 mg, Cu (as copper sulfate) 12.5 mg, Mn (as manganese sulfate) 30 mg, Zn (as zinc sulfate) 90 mg, Se (as sodium selenite) 0.3 mg, I (as potassium iodide) 1.0 mg, Co (as cobalt chloride) 0.5 mg.
All results were measured values.
DE (%)= 4.184 × 0.7 × [(0.057 × CP%) + (0.092 × EE%) + (0.0415 × carbohydrates%)], where carbohydrates % = 100 – EE% – CP% – Ash%, from NRC 2001.
