Abstract


Investigation carried out in this study focused on the urinating frequency and factors that has an influence on them, in 9 Romanian Black and White primiparous cows, during the first hundred days of lactation, in tied stalls. The aim of this study was to measure the urinating frequency of the cows in 24 hours that were divided into 3 day periods: 07:00-14:00, 14:00-21, 21:00-07:00, according to administration order of the fodder (fibrous-succulents and succulents-fibrous). Results: during the first hour interval (07°°-14°°), in the first order (O1) the urinating frequency is increasing slightly from 4-5 cows during the first hours up to 8 cows urinating at the of interval. In the second order (O2) the urinating frequency is almost constant, being lower between 11:00 and 12:00. In the second hour interval (14°°-21°°), in the first order (O1) the lowest urinating frequency was found at the beginning of the interval, when 4 cows urinated, and the highest frequency at the end of interval with 8 cows urinating. In the second order (O2) the urinating frequency is relatively constant, the minimum value of 6 cows being at the middle of this interval, and the maximum of 8 cows at the end of interval. In the third hour interval (21°°-07°°), for both orders, the urinating frequency slightly decrease to 2-3 urinations until midnight, then increase to 8-9 until first hour in the morning.
