STUDY ON THE RESTING BEHAVIOR IN ROMANIAN BLACK AND WHITE PRIMIPAROUS COWS

The study was carried out on 3 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 resting behavior of the cows in 24 hours that were divided into 3 day periods: 07:00-14:00, 14:00-21:00, 21:00-07:00. During the experiments, the following resting behavior aspects were determined: number of periods standing, number of periods lying, the length of the periods. Data was computed by ANOVA/MANOVA. Results showed that the cows spent on average 81.83 minutes standing and 25.33 minutes lying in 07:00-14:00 day period, 80.66 minutes standing and 66.33 minutes lying in 14:00-21:00 day period and 47.83 minutes standing and 137.66 minutes lying in 21:00-07:00 interval. The cows spent on average 75.77% standing and 24.23% lying from a first interval length, 55.49% standing and 44.51% lying from a 14:00-21:00 day period and 26.16% standing and 73.84% lying from a 21:00-07:00 interval.
