† Hybrids that have any MS letter in common are not significantly different at the 5% level of probability.

‡ For a full description of abbreviated biotech traits, see table 13.

NDF = Neutral Detergent Fiber

30h IV NDFD = Neutral Detergent Filber Digestibility

ADF = Acid Detergent Fiber

TDN = Total Digestable Nutrients

NEL = Net Energy for Lactation
