COMPARATIVE ANALYSIS OF MORPHOLOGICAL CHANGES OF PLACENTA OF COWS AT PHYSIOLOGICAL DETACHMENT OF PLACENTA AND RETENTION OF PLACENTA OF COWS

It was conducted a comparative analysis of macro and
micro changes in the placenta of cows at the physiological
flow of lazing-in and at the retention of placenta. Morphometric
analysis revealed that in case of placenta retention it mass,
cotyledon area and fetus-placenta correlation. At histological
research the processes, typical of local tissue hypocsia of
chronic character, were marked. However, it was revealed
good development of compensator-adaptation changes,
allowing to get viable offspring.
