[Tracheal collapse in a four month old Uckermaerker heifer]

Area of Science:

• Veterinary Pathology
• Animal Genetics

Background:

• Tracheal collapse is a rare condition in cattle.
• Understanding its etiology is crucial for herd management.

Observation:

• A four-month-old Uckermaerker heifer presented with acute dyspnea and respiratory failure.
• Necropsy revealed collapse in the middle and caudal trachea due to inward bending of cartilage rings.
• Severe luminal reduction was noted in the thoracic trachea.

Findings:

• Pathological findings suggest a non-traumatic cause for tracheal collapse.
• Inbreeding (coefficient 0.125) was identified in the animal's breeding scheme.
• Hereditary factors are strongly suspected as the primary cause.

Implications:

• This case suggests a potential genetic predisposition to tracheal collapse in this breed.
• Further research into genetic factors influencing tracheal integrity is warranted.
• Highlights the need for careful breeding practices to avoid inbreeding depression and associated health issues.
