Abstract


The study was carried out on 9 Romanian Black and White cows in their first hundred days of lactation. The aim ofthis study was to measure the main aspects that characterized the excretion behaviour (defecation) of the cows in 24hours that were divided into 3 day periods: 07:00-14:00 (I1), 14:00-2:001 (I2), 21:00-07:00 (I3). During theexperiments, the following defecation behaviour aspects were determined: total number of defecations, number ofdefecations in the three intervals, number of defecations according to administration order of forages (fibroussucculentsand succulents-fibrous). Data was computed by ANOVA/MANOVA. Results showed that the differencesbetween intervals I1-I2 and I1-I3 were statistically very significant (p< 0.01). In fibrous – succulent order thedefecation were 0.69 higher than in succulent- fibrous order (p< 0.01). Total number of defecation resulted bysumming the defecation from the three intervals, was 14.67 in the first administration order (fibrous-succulent) and12.61 in the second administration order (succulent-fibrous).
