- •
Supplementation of Phe to early lactation cows receiving 170 g/kg of diet DM as CM.
- •
Phe changed energy utilization, decreasing milk lactose while increasing BCS gain.
- •
Phe resulted in an increase in whole tract aNDFom and ADF digestibility.
- •
Phe support milk production after restoring mobilized peptides to muscle protein.
- •
Phe regained animal performance lost when CM inclusion was increased.
