Aim: Pigs are extensively used as experimental models to study the human physiology and pathophysiological conditions. Knowledge of the normal values of the commonly used parameters is indispensable to the correct interpretation of the test results. This study reports on the normal hemogram, blood gas, major electrolytes, kidney and liver profiles, hepatic oxygen consumption, and net lactate production in a large white pig model. Methods: Twenty-five female large white pigs were included in this study. Blood gas samples were collected from the portal and hepatic veins as well as the carotid artery. Results: The mean hemoglobin level was 97.7 ± 15.8 g/L. white blood cells were 13.5 ± 3.3 10 [3] /mm [3] , and platelet count was 279 ± 104.6 10 [3] /mm [3] . The mean aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, alkaline phosphatase, total bilirubin, and direct bilirubin were 83.8 ± 73.9 IU/L, 43.7 ± 5.9 IU/L, 33.6 ± 8.6 IU/L, 296.5 ± 39.7 IU/L, 5.6 ± 3.2 mmol/L, and 1.6 ± 0.73 mmol/L. The mean albumin level was 29 ± 3.9 g/L. The mean ammonia and arterial lactate levels were 49.1 ± 45.67 mmol/L and 1.5 ± 0.46 mmol/L. Kidney profile parameters were comparable to human values. Hepatic oxygen consumption was 17.3 ± 9.7 mL/100 g liver tissue/min and net hepatic lactate production was 0.017 ± 0.03 mmol/L. Conclusion: Knowledge of the normal parameters is mandatory for accurate interpretation of the experimental results that involves large white animals.
