Chemical composition of the total mixed-ration (TMR) fed to the rumen-fistulated dry cows. Dietary analysis conducted by Cumberland Valley Analytical Services (Hagerstown, MD) completed 12/01/2016. Ingredient composition of TMR on an as is a basis was 50% wheat hay, 25% alfalfa hay, 21.4% almond hulls and 3.6% mineral supplement.
a Acid detergent fiber (ADF); Ash free Neutral Detergent Fiber (aNDF); Total Digestible Nutrients (TDN).
b Dry Matter (DM); Crude Protein (CP); Neutral Detergent Fiber (NDF).
c Calculations for net energy metrics were estimated as described in Linn [29].
