MORPHOMETRY OF EQUINE PLACENTA

摘要

The Growth and development of fetus is dependent upon placenta of individuals functional capabilities. In this study morphometry of placenta of fifty six thorough breed mares aged between 9 to 13 years were studied after normal foaling in which the foals born were alive. The prototype of expulsion, gross morphology, morphometry, placental expulsion time, and umbilical cord length was studied. All placenta were expelled 1 with the allantoic side (non-villous surface) of ailantochorion outermost. The mean placental expulsion time was 66.89± 3.90 min. The mean length of pregnant horn, non-pregnant horn, total body, posterior body and anterior body of pregnant horn were 63.49+0.81, 56.63±0.81, 132.64±0.98, 67.52± 1.11 and 107.93± 1.02cm respectively. The umbilical cord length was 60.30±1.04cm. The mean weight of the total placenta was 4.70±0.11kg. Morphometry of placenta can be used as a determinant of foals well being.
