The study was carried out on 9 Romanian Black and White cows in their first one hundred days of lactation. The aim of this study was to measure the main aspects that characterized the excretion behaviour (urination) of the cows in 24 hours that were divided into 3 day periods: 07:00-14:00, 14:00-2:001, 21:00-07:00. During the experiments, the following urination behaviour aspects were determined: total number of urination, number of urination in the three intervals, number of urination according to administration order of forages (fibrous-succulents and succulents-fibrous) .Data was computed by ANOVA/MANOVA. Results showed that the all the differences between intervals were statistically non-significant (p< 0.05). In succulent-fibrous order the urination were 0.66 higher than in fibrous-succulent order (p< 0.01). Total number of urination resulted by summing the urination from the three intervals, was 14.11 in the first administration order (fibrous-succulent) and 16.06 in the second administration order (succulent-fibrous).
