An experiment was made with 22 Friesian cows, using a double reversal design with 2 treatments and one similar sequence for the 2 groups. The lengths of the standardization period, adaptation periods, test period and post-test period were 4, 1, 8 and 4 weeks, respectively. During the standardization and post-test periods the cows received pre-wilted grass silage to appetite and a small amount of field-dried baled hay.
