Gastrointestinal obstruction in penguin chicks

Area of Science:

• Avian Medicine
• Zoological Pathology

Background:

• Gentoo penguins (Pygoscelis papua) are susceptible to various health issues in captive environments.
• Gastrointestinal impactions can be life-threatening in developing penguins.

Observation:

• A 7-day-old gentoo penguin chick died due to ventriculus impaction with feathers.
• A review identified a sibling chick with a similar feather impaction, indicating potential familial predisposition.
• A king penguin (Aptenodytes patagonicus) chick presented with omphallitis, enteritis, and intestinal obstruction by a fibrin mat.

Findings:

• Feather impaction of the ventriculus is a significant cause of mortality in young gentoo penguins.
• Gastrointestinal obstruction, whether by foreign material (feathers) or endogenous material (fibrin), poses a critical threat to penguin health.
• Concurrent omphallitis and enteritis may contribute to the formation of obstructive fibrin mats in penguin chicks.

Implications:

• Understanding impaction causes is crucial for preventative care and husbandry in zoological collections.
• Early detection and intervention strategies for gastrointestinal issues in penguin chicks are essential for improving survival rates.
• Further research into dietary and environmental factors influencing feather ingestion and fibrin mat formation is warranted.
