【 摘 要 】

The aim of this paper was to measure the main aspects that characterize the drinking behavior of three months old calves. During the experiments the following drinking behavior aspects were determined: number of drinking periods, the length of drinking periods. Results showed that in the winter season the total length of drinking periods was 7.0 minutes in the morning, 5.1 minutes in the afternoon and 2.4 minutes during the night. In the summer (high temperatures) the total length of drinking periods was 7.9 minutes in the morning, 10.0 minutes in the afternoon and only 4.0 minutes during the night. In the summer (normal temperatures) the total length of drinking periods was 5.8 minutes in the morning, 7.9 minutes in the afternoon and only 4.4 minutes during the night. Calves spent drinking on average 14.5 minutes in the winter, representing 1% of a day length. Calves spent drinking on average 21.9 minutes in the summer when the temperatures were very high, respectively 1.5% of a day length. Calves spent drinking on average 18.1 minutes during the summer when temperatures were normal (1.3%).
