Distribution and etiology of placenta detention in horses
Abstract
In connection with the fact that detention of fetus membranes is the most common obstetrical pathology after dystocia, that leads to in fertility of mares, and often en dangers the very life of the animal; it is regarded by experts in veterinary medicine as potentially more serious pathology than the same in cattle, it is impossible to over estimate its importance for preserving fertility. The aim of the study was comprehensive processing and analysis of literature data on distribution and etiology of placenta detention in horses and their generalization. Frequency of placenta detention in mares ranges from 2 to 13%, and in mares of Frisian breed it can be 30-54% of all birth cases. Animals with this pathology have an increase drisk of recurrence of the disease in future. According to many authors, detention of fetal part of placenta is a polyethiological disease. The immediate reason for detention is circulation of blood in maternal part of placenta, caused by violation of homeostasis in its microcirculatory vascul arbed.
