Dietary cation-anion difference was defined as the summation of the milliequivalents of Na and K minus the sum of the milliequivalents of Cl and S per kilogram of DM. Twelve Holstein cows were used in a crossover experiment to compare the effects of changing the cation-anion difference of a diet based on haylage. Two cation-anion differences, 481.8 and(More)
Three switchback experiments were conducted with 12 cows in early lactation, 12 cows in midlactation, and 12 cows in late lactation. Each experiment compared two dietary cation-anion differences. Increasing dietary cation-anion difference increased DMI and milk production in early and midlactation. These effects were not observed in late lactation.(More)
Ten Holstein and 2 Ayrshire cows were used in a switchback design to compare diets based on alfalfa haylage and corn silage. Both diets had a similar cation-anion difference and contained 1% NaHCO3. Dietary treatment did not affect DMI, DM digestibility, milk production, or milk composition. Intake, absorption, and urinary excretion of N were significantly(More)
