STUDY ON RESTING BEHAVIOR IN THREE MONTHS OF AGE CALVES FROM ROMANIAN BLACK AND WHITE BREED DURING WINTER
Abstract
The aim of this paper was to measure the main aspects that characterize the resting behavior of three months old calves. During the experiments the following resting behavior aspects were determined: number of resting periods, the length of resting periods. Results showed that in the winter season the total length of laying down periods was 171.5 minutes in the morning, 222.8 minutes in the afternoon and 403.9 minutes during the night. In the winter season calves stood down in 3.7 periods during the morning, 4.4 periods during the afternoon and 2.9 periods during the night. There were significant differences between morning and afternoon (p<0.001), between morning and night (p<0.001) and between afternoon and night (p<0.001) for total time spent lying down. In the winter season the total time spent resting (sleep and rest laying down) was 79.7 minutes in the morning, 115.8 minutes in the afternoon and 239.6 minutes during the night. There were significant differences between morning and afternoon (p<0.01), between morning and night (p<0.001) and between afternoon and night (p<0.001) for total time spent resting by calves.
