title: [Radiotelemetric studies on uterine motility in cows during the 3d period of labor and the early puerperal period].
abstract: The outside appearance of a one-channel radiotelemetric system is presented and a short description of supplementary devices for the study of uterine motility in cows is given. The radiotube consisting of an inductive converter and a two-transistor sound generator is described in short. The tube is placed directly in the uterine cavity through the cervical canal. The numerical values of contractile uterine activity in hours post delivery up to the 120 hour are presented in one table and a graph. Original registering of normal uterine activity and of reflectory inhibition of the same are shown as well as registerings of other functions of the organism through the uterus such as urination, defecation, lowing and belching. The contractile activity of the uterus during a normal course of the third stage of labour and the early puerperium is most strongly expressed during the first day post calving. The duration of this activity in the following days is directly dependent on the individual characteristics of the organism.
