Area of Science:
- Veterinary Pathology
- Sheep Medicine
- Toxicology
Background:
- Pastured Katahdin lambs are susceptible to various health challenges.
- Sudden unexplained mortality in young livestock requires prompt investigation.
Observation:
- A group of 3-4 week old Katahdin lambs experienced acute mortality within 24 hours.
- Clinical signs included hemoglobinuria, weakness, recumbency, and severe anemia (PCV 4%).
Findings:
- Postmortem examinations revealed icterus, hemoglobinuric nephrosis, pulmonary edema, and hepatocellular damage.
