Age-related changes in plasma biochemical values of farmed emus (Dromaius novaehollandiae)

Blood samples were collected from 40 emus (Dromaius novaehollandiae) of 4 different age groups ranging from 1 week to 14 months. Plasma values of glucose, cholesterol, uric acid, total protein, albumin, creatine kinase, aspartate amino transferase, alkaline phosphatase, calcium, phosphorus and magnesium were measured. Fourteen-month-old birds had lower plasma glucose values and enzyme activities and higher plasma protein values than younger birds. One-week-old birds had higher cholesterol and uric acid values than other age groups. Plasma calcium, phosphorus and magnesium values did not differ across the age profiles sampled.
