Re-examining poikilocytosis in goats: prevalence, type and association with age and disease.

These findings suggest that iron deficiency is an important pathophysiologic mechanism of poikilocytosis in juvenile and adult goats, and possibly in kids, whether due to iron-restricted erythropoiesis, chronic hemorrhage, functional iron deficiency, or a combination of these mechanisms. Further investigation into the detection and monitoring of iron deficiency and the value of poikilocytosis as a diagnostic marker of iron status in goats is warranted.
