Abstract
The research was performed by videorecording of the chosen sows and piglets, which differed in breed, age and parity and were placed in two objects with different flooring, during day 20 after farrowing. The purpose was to investigate the vocal-tactile communication between the sow and the piglets. The sows with their piglets were divided in two groups, each consisting of 5 sows. Each sow was videotaped continuously during 6 hours. During the recording, bioclimatic parameters were also controlled. The results obtained were statistically analysed and compared applying the t-test. The analysis revealed a significant difference (P<0.05) between suckling initiated by vocal and tactile communication in Object A. The suckling frequency and duration changed with the aging of piglets. Most of the suckling during day 20 after farrowing was initiated by the piglets, by tactile communication with the sow.
