Acta vet. scand. 2003 44 131-143. - Early postpartum 6 weeks ovarian activity hormonal profiles uterine involution uterine infections serum electrolytes glucose milk acetoacetate and blood urea nitrogen BUN levels were studied in 2 Estonian high producing dairy herd with annual milk production of 7688 Farm A and 9425 Farm B . From each farm 10 cows with normal calving performance were used. Blood samples for the hormonal PGF2a-metabolite progesterone analyses were withdrawn. On day 25 PP blood serum samples were taken for the evaluation of metabolic electrolyte status. On the same day estimation of milk acetoacetate values was done. The ultrasound US was started on day 7 PP and was performed every 3rd day until the end of experiment. Uterine content follicular activity and sizes of the largest follicle and corpus lu-teum were monitored and measured. Vaginal discharge and uterine tone were recorded during the rectal palpation. Each animal in the study was sampled for bacteriological examination using endometrial biopsies once a week. Two types of PGF2a-metabolite patterns were detected elevated levels during 14 days PP then decline to the basal level and then a second small elevation at the time of
