1. Quality factors taken from the replicated silage trial at Tifton.
2. This variable is calculated using University of Wisconsin Corn Silage Evaluation System - Milk 2000 and reported at
lbs milk/ton of dry matter (DM) and lbs milk/acre.
3. NDF48: Percent dry matter disappearance/48 hours.
4. CV = 2.7%, and df for EMS = 41.
5. CV = 2.8%, and df for EMS = 41.
6. The F-test indicated no statistical differences at the alpha = 0.10 probability level; therefore an LSD value was not
calculated.
Bolding indicates entries performing equally to highest performing entry within a column based on Fisher's protected
LSD (P = 0.10).
