Key Points
- Laboratory quality test results vary widely in the period from grain growth stage 75 to 91.
- MEs generally improved from GS 75 to GS 85, but change after this was variable.
- Digestibility laboratory tests changed little, this may differ from actual animal responses.
- Proteins declined throughout this period.
- Starch and soluble sugars increased throughout this period.
- These changes are generally similar within cereal species types, but some cultivars vary.
