The alteration in the serum biochemical parameters are strongly associated with the health status of birds, and have assessed to check the health ailment against the heavy metal toxicity. Blood samples were collected from different groups of pigeons after 48 h of the low dose (10 µg/g) and high dose (20 µg/g). The mean level of alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT), alkaline phosphatase (ALP), Uric acid and Creatinine was highly fluctuated with the low dose of cadmium (Cd-L), high dose of cadmium (Cd-H) and high dose of Zinc (ZnH) whereas low dose of zinc (Zn-L) showed less impact on enzymes activities i.e., Cd-H > Cd-L > Zn-H > Zn-L. The pigeons of control groups exhibited high significance difference (P Cd-H > Zn-L > Zn-H. The trend of relative weight (%) for paired kidney was Cd-L > Cd-H > Zn-H > Zn-L. The alteration in activities of enzymes and relative weight showed significance difference (P < 0.05) with low and high dose of cadmium and zinc. The level of serum enzymes activity increased significantly with low and high dose of cadmium and exhibited its high toxicity as compared to the Zinc.
