title: [Effect of mammary gland diseases, the act of sucking and machine milking on utering motility in cows during the early puerperal period. I].
abstract: The effect of some mammary gland diseases, of the act of sucking and of machine milking on spontaneous uterine activity was studied in cows during their early puerperal period by use of the radiotelemetric method. It was established that clinical catarrhal and suppurating mastitis block spontaneous uterine activity. However, the uterus preserves its reactivity to oxytocin which is confirmed by injection of the hormone. The act of sucking and machine milking have a positive effect on spontaneous uterine activity up to the 5--7 days following calving. Uterine contractions are registered after reflectory influences too. The number and amplitude of uterine contractions 48 h after calving are closely correlated with the predisposition of uterine musculature to post calving complications.
