Quality Index:
Dairy = 50 percent NDF digestibility rating + 50 percent whole-plant digestibility rating.
Beef = 50 percent NFC digestibility rating + 50 percent whole-plant digestibility rating. |
Glossary:
NFC = Energy primarily from grain (higher value = higher energy content)
WPD = Portion of plant used (higher value = less waste)
NDF = Fiber Content (higher value means more fiber and possibly less intake)
CWD = Fiber digestibility (higher value = more nutrients from fiber) |

Notes:
|
- Relative Maturity Days compare normal maturity day differences between hybrids.
- Actual days may vary considerably from those shown due to growing degree unit accumulation.
- Growing Degree Unit (GDU) accumulation may vary within the geographic region as a result of temperature and environmental variations.
- Ratings based on best current information available and may be affected by changing conditions.
