ABSTRACT

The research was conducted on 7 inter-breed hybrid sheep, at the age from 10 to 48 months and of the body mass of 32-47 kg, which had bipolar electrodes implanted to the uterus shank and horns. The registration of uterus myoelectrical activity was performed on non-sensitised sheep and 24-48 hours after stilboestrol sensitisation, with the use of electroencephalograph. After recording the output activity, the sheep were administered in continuous infusion: adrenaline – agonist of alpha and beta – adrenergic receptors in the dose of 0.12-0.18 μg ˇ kg^-1 ˇ min^-1; detomidin – agonist of alpha-adrenergic receptors in the dose of 0.1 – 1.1 μg ˇ kg^-1 ˇ min^-1; phenylephryn – agonist of alpha₁-adrenergic receptors in the dose of 2.1 – 2.9 μg ˇ kg^-1 ˇ min^-1; xylasine – agonist of alpha₂-adrenergic receptors in the dose of 0.5 – 4.0 μg ˇ kg^-1 ˇ min^-1; prazosin – antagonist of alpha₁

Key words: sheep, uterus, myoelectrical activity, alpha – adrenergic receptors.
