Uterine and cervical involution after calving was measured sequentially in 25 parous commercial Friesian cows by using electronic callipers and real-time ultrasound imaging, transrectally. Ovarian activity was monitored by using real-time ultrasound imaging and by milk progesterone concentrations. Peripheral plasma prostaglandin F2 alpha metabolite concentrations were assayed during this period.
