Abdominal pregnancies in farm rabbits.

Abdominal pregnancy is defined as the implantation and development of a fertilized ovum or a embryo in the peritoneal cavity. Although this has been reported in several species, it is considered as a low incidence process. It is classified as a primary abdominal pregnancy, if there is no evidence of uterine rupture, with presumed regurgitation of early embryos from the uterine tube and as a secondary abdominal pregnancy, when there is evidence of uterine rupture.
