Water Partitioning and Intake Prediction in Dry

Data from four energy and N balance trials with lactating Holstein cows (n = 329) and one trial with dry cows (n = 60) were used to predict free water intake and water-related traits. Lactating cows were between 36 and 159 DIM and. indi-vidually, were allowed ad libitum water and forage (com silage without or with wilted haycrop silage) plus concentrates; dry cows accessed ad libitwn water and single forages (grass, clover, or alfalfa, as hays or as wilted silages, or com silage) varying in maturity.
