Third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (Goetz
technique). Primary healing occurred in all of them without any complication. The conception rate obtained
after surgery was 70.1%. Five horses out of seven got pregnant after surgery and no further injury was seen at
subsequent foaling. Three mares have produced several healthy foals without any subsequent injury.
According to the results of the present study, single-stage surgical repairof third-degree perineal laceration
(Goetz technique) appeared tohave a good prognosis for subsequent fertility in mares.
