ABSTRACT

The research was conducted on 5 inter-breed hybrid sheep, at the age of 10 to 24 months and of the body mass of 30-45 kg, which had bipolar electrodes implanted to uterus horns and shank. The registration of uterus myoelectric activity was performed on sheep 24 and 48 hours after sensitising with Stilboestrol, by the use of Reega Duplex TR XVI electroencephalograph. After recording the output activity, the sheep were applied intravenously in continuous injection: adrenaline – 0,12-0,18 μg ˇ kg^-1 ˇ min^-1, oxytocin – 0,25-0,4 i.u., propranolol – 1mg ˇ kg^-1, isoprenaline – 0,4-1,5 μg ˇ kg^-1 ˇ min^-1, salbutamole – 0,4-0,8 μg ˇ kg^-1 ˇ min^-1. The experiment results are presented in the inclosed drawings. The conducted research revealed that the stimulation of beta-adrenergic receptors causes the decrease or inhibition of uterus myoelectric activity of sheep sensitised with Stilboestrol.

Key words: sheep, uterus, myoelectric activity, beta-adrenergic receptors.
