* Hybrids marked with an asterisk were in the top performing “A” group for yield within two (**) or three (***) consecutive years of the previous three year evaluation period.

† For a full description of abbreviated biotech traits, see table 5.

‡ Hybrids that have any MS letter in common, within a column, are not significantly different at the 5% level of probability using a least significant difference (LSD) mean separation test.

- Based on University of Wisconsin Milk2006 software program.

‖ Lodging data was transformed due to non-normality. Least square means were back-transformed for ease of interpretation, therefore mean separation letters but no LSD value are given.

¶ Quality values were calculated on a 100% dry matter (DM) basis

CP = Crude Protein, NDF = Neutral Detergent Fiber, 30h IV NDFD = Neutral Detergent Fiber Digestibility, ADF = Acid Detergent Fiber, TDN = Total Digestible Nutrients, NEL = Net Energy for Lactation
