Mummification is often noticed in pigs compared to other species due to large litter size. The agents responsible for the reproductive failure in sows may lead to a wide range of sequelae, including abortions, stillbirth, mummification, embryonic death. High prolificacy is associated with increased incidence of stillbirths and mummified fetuses. Plethoras of other foetal and maternal factors have been associated with incidence of still birth and mummification. Identification of those risk factors have been associated with stillbirth and mummified fetuses can helps in optimal herd reproductive efficiency.
