ResumoThe effects of stimulants and inhibitors of adrenergic receptors on the myoelectric activity were studied in pregnant cows at different points of the last trimester of pregnancy. The results showed that noradrenaline produced an increase of the myoelectric activity of the uterus specially at the 6th week before parturition. Furthermore i.v. infusion of propranolol potentiated and of phentolamine diminished the stimulating activity of noradrenaline.
