Abstract     The aim of this study was to evaluate the electromyographic (EMG) activity of smooth muscles of uterine cervix (UC) and uterine horn (UH) in sheep during pregnancy and parturition in time/frequency domain and to recognize the differences between the two activities. The uterine electromyographic activity was recorded in eight sheep by electrodes, surgically implanted on UC and UH during pregnancy, parturition and postpartum. The data was sampled and stored digitally on a PC computer in real time. All data processing was made off-line in the time/frequency domain. The results of the time/frequency analysis showed that the activity in UC and UH was changing during different observed periods and that there are differences between the muscles activity in UC and UH. The use of the time/frequency distribution (FTD) has been recognized as a successful method for analysis of smooth muscles activity in the UC and UH during pregnancy and parturition in sheep.
