ABSTRACT

Abnormal embryological development of the female reproductive tract may lead to incomplete perforation, canalisation, duplication or partial or complete agenesis or aplasia. A variety of tumours have been reported, including adenocarcinoma, leiomyoma or leiomyosarcoma, and lymphoma. These may affect any part of the tubular reproductive tract and also the broad ligament. Embryo transfer allows proliferation of genetically superior females or expansion of small breed populations. Definitive diagnosis is based on a demonstration of the virus either in cell culture or by means of other available tests such as polymerase chain reaction. Ascertaining the cause of abortion in goats requires a thorough, well-structured investigation including an assessment of the environment and any nutrition and management factors, in addition to gathering material for laboratory examination. In South Africa, where marked genetic selection for fine-quality mohair has been undertaken, there has been an apparent parallel selection for genetic habitual abortion.
