Methods for recording uterine contractions in cows after the normal course of calving

The research is devoted to the study of contractility myometrium in cows using a rubber balloon and piezoelectric pressure sensor. It has been established that with an increase time after calving, number uterine contractions, values intrauterine contraction index gradually decrease. have decisive influence on value index. most convenient method for studying contractile function uterus can be considered use sensor connected computer system processing data obtained, which significantly speeds up analysis objectivity results hysterographic studies.
