Abstract: Plasma biochemical values were determined in 14 healthy adult (52-75 week old) and 14 healthy young (8-10 weeks old) local Sudanese geese. The young birds had significantly greater aspartate amino transferase (AST) and Alanine Lmino Transferase (ALT) values than the adult birds. The alkaline phosphatase (ALP), inorganic phosphate, bicarbonate (HCO3), sodium (Na), potassium (K) and chloride (Cl) levels in the young bird were not significantly different from those of the adult duck. The total protein, albumin, globulin, uric acid and creatinine values were also similar in the young and adult birds.
