Gross and histopathological evaluation of umbilical outpouchings in pigs.

Clinical presentations of umbilical outpouchings (UOs) in pigs cover a variety of pathological manifestations. Pigs with UOs often do not reach the abattoir as they die due to complications or are euthanized for welfare concerns. The primary objective was to characterize the gross appearance of UOs in pigs with respect to the different types of pathological manifestations.

Survival of pigs with different characteristics of umbilical outpouching in a prospective cohort study of Danish pigs.

The objectives of the current study were to characterize the associations between 1) time of detection of the UOs and the odds of dying before scheduled slaughter; 2) time of death, irrespective of the cause, and clinical signs of the UOs, i.e.
