Abstract: The present study was conducted to assess the effect of inorganic, organic and nano-zinc supplementation on haemato-biochemical profile of lactating Kankrej cows. Twenty-four Kankrej cows were assigned randomly into four equal groups. The four groups were as C (control): Basal diet; T₁: Basal diet + 40 mg/kg of DM of inorganic zinc supplementation; T₂: Basal diet + 40 mg/kg of DM of organic zinc supplementation and T₃: Basal diet + 20 mg/kg of DM of nano- zinc supplementation daily. The duration of experiment was of 120 days. The blood samples were collected at the end (120^th day) of experimental feeding. The haemoglobin and hematocrit values were without significant (p>0.05) difference among the treatment groups. No effect (p>0.05) on red blood cells (erythrocytes, MCV, MCH and MCHC) and white blood cells (leucocytes, neutrophils, lymphocytes, monocytes and eosinophils) count were observed due to dietary addition of different sources of zinc in the diet. The serum concentrations of glucose, total protein, albumin, globulin, urea, creatinine, cholesterol, ALT and AST were not affected (p>0.05) by the dietary supplementation of inorganic, organic and nano-zinc in the diet. Based on the results, it may be concluded that supplementation of inorganic, organic and nano-zinc at the dose rate of 40, 40 and 20 mg/kg of DM, respectively, in the diet of lactating Kankrej cows did not have any adverse effect on haemato-biochemical parameters.
