Topic:Dystocia
Dystocia in horses refers to difficult or abnormal labor that complicates the birthing process. It can result from various factors, including fetal malposition, abnormal fetal size, or maternal pelvic conformation. Dystocia poses risks to both the mare and the foal, necessitating timely veterinary intervention to resolve delivery complications. Management strategies may involve manual correction, assisted delivery, or surgical intervention such as a cesarean section. This page compiles peer-reviewed research studies and scholarly articles that explore the causes, management, and outcomes associated with dystocia in equine reproduction.
Obstetrician’s view of the physiology of equine parturition and dystocia. The author reviews 40 years of clinical experience including more than 1000 cases of dystocia in mares of different breeds. The high incidence of stillbirth and perinatal mortality of the foal, severe lesions of the genital tract developing during foaling and in the early post partum period are discussed and suggestions made for their prevention and treatment. The advantages of partial embryotomy to avoid unnecessary caesarean sections are emphasised. Special attention is given to the causes of and approach to cases of prolonged gestation; to dystocia caused by retroversion of preparturient to...
Dropsy of the fetal sacs in mares: induced and spontaneous abortion. Eight cases of severe dropsy of the fetal sacs have been observed in mares. All were in multiparous mares whose ages ranged from five to 20 years and who were 7 1/2 to 10 3/4 months pregnant. Abortion started spontaneously in four cases and had to be induced in the remaining four by manual dilation of the cervix, rupture of the tough allantochorion and the siphoning off of 120 to 220 litres of allantoic fluid. The amnion was normal. Dystocia, due to uterine inertia, occurred in all eight cases, one hydrocephalic fetus needing fetotomy. All fetuses were alive at delivery although four were tera...
