VOCAL AND TACTILE COMMUNICATIONS BETWEEN SOWS AND PIGLETS AFTER BIRTH, DURING THE FIRST DAY

Učestalost i trajanje sisanja zasnovanog na glasovnoj i taktilnoj komunikaciji između krmače i prasadi tijekom prvih 6 sati nakon prasenja, snimljeno je na video-trake. Snimano je 10 krmača, podijeljenih u dvije skupine, smještene u dva različita objekta s različitom vrstom poda. Krmače su se međusobno razlikovale po pasmini, dobi i broju prasenja. Dobiveni rezultati statistički su obrađeni i uspoređeni pomoću t-testa. Značajna statistička razlika (P<0,05) zabilježena je s obzirom na vrijednost učestalosti glasovne komunikacije, između krmača u objektu A i B, te s obzirom na učestalost i trajanje vokalne/taktilne komunikacije u objektu A. Tijekom istraživanja, u oba su objekta kontrolirani i mikroklimatski čimbenici.Nursing frequency and duration based on vocal and tactile communication between the sow and the piglets was video-taped during the first 6 hours after farrowing. The recording included 10 sows, divided in two groups and placed in two objects with different flooring. The sows differed in breed, age and parity. The obtained results were statistically analysed and compared applying the t-test. A significant difference (P<0,05) was found considering frequency values of vocal communication between the sows in Objects A and B, and between the frequency and duration of vocal/tactile communication in Object A. During the research micro-climatic factors were also monitored in both objects

VOCAL AND TACTILE COMMUNICATIONS BETWEEN SOWS AND PIGLETS ON DAY 20 AFTER FARROWING

lstraživanje je obavljeno videosnimanjem odabranih krmača i prasadi različitog pasminskog sastava, starosne dobi i broja prasenja u dva različita objekta s obzirom na vrstu poda tijekom dvadesetog dana nakon prasenja, a cilj je bio istražiti glasovno-taktilnu komunikaciju između krmača i prasadi. Krmače s prasadi podijeljene su u dvije grupe po 5 životinja. Svaka je krmača snimana neprekidno 6 sati. Za vrijeme video snimanja kontrolirani su i mikroklimatski uvjeti. Dobiveni rezultati stratistički su obrađeni i uspoređeni pomoću t-testa. Značajna statistička razlika (P<0.05) zabilježena je između sisanja na osnovi glasovne i traktilne komunikacije u objektu A. Učestalost i trajanje sisanja sa starenjem prasadi se mijenja. Najveći broj sisanja u tijeku dvadesetog dana starosti prasadi biva potaknut od same prasadi, taktilnom komunikacijom prasadi s krmačom.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

VOCAL AND TACTILE COMMUNICATION BETWEEN SOWS AND PIGLETS AT DAY 10 AFTER FARROWING

Učestalost i trajanje sisanja zasnovanog na glasovnoj i taktilnoj komunikaciji između krmače i prasadi na dan 10. nakon prasenja, snimljeni su na video vrpce. Tijekom 6 sati snimano je 10 krmača, podijeljenih u dvije skupine, smještene u dva različita objekta s različitom vrstom poda. Krmače su se međusobno razlikovale po pasmini, dobi i broju prasenja. Dobiveni rezultati statistički su obrađeni i uspoređeni pomoću t-testa. Među promatranim skupinama nije zabilježena značajna statistička razlika. Tijekom istraživanja, u oba su objekta kontrolirani i mikroklimatski čimbenici.Nursing frequency and duration based on vocal and tactile communication between the sow and the piglets was video-tapet for 6 hours at day 10 after birth. The recording included 10 sows, divided in two groups and placed in two buildings with different flooring. The sows differed in breed, age and parity. The results obtained were statistically analysed and compared applyng the t-test. The analysis didn\u27t reveal any statistical difference between groups. During the research microclimatic factors were also monitored in both objects
