The main aim of the study was to determine the usefulness of haptoglobin in the early postpartum period by monitoring the therapy of retained fetal membranes in cows. 52 cows were included in the study and divided into four testing groups of cows with retention of fetal membranes after their manual removal or natural separation, as well as one group without retention of placenta. The concentrations of haptoglobin were performed as an adaptation of the Jones-Mould method and compared between all groups of cows in twofold blood samplings at 3 and 10 days after calving. Haptoglobin that was estimated in the early postpartum period was demonstrated as a good marker for monitoring the results of different methods of therapy of fetal membrane retention in cows.
