It was also accompanied by a significant increase in blood albumin (17.5 vs. 16.9 g/L), creatinine (114.3 vs. 112.9 µmol/L), uric acid (0.86 vs. 0.78 mmol/L) and ALAT (34.3 vs. 27.5 UI/L) levels in birds concerned compared with controls, whereas total protein and ASAT levels were similar (p˃0.05). Indeed, all biochemical parameters levels studied were in line with the corresponding reference values in broilers both for controls and supplemented birds, with the exception of uric acid content in blood which were higher.

AB  - Creatine, a natural component synthesized in liver and kidneys from guanidinoacetic acid (GAA), is mainly used in muscle tissue, due to its major role in energy metabolism.
