A study was conducted to evaluate the efficiency of nano zinc (NZn) as feed supplementation on haematological and blood biochemical profiles in goats (Capra hircus). NZn was synthesized by from 0.45 M aqueous solution of zinc nitrate [Zn(NO3)2.6H2O] and 0.9 M aqueous solution of sodium hydroxide (NaOH). The particle size thus obtained was 74 nm and later it was confirmed to be zinc by using TEM-EDAX. Twenty four male goats were divided into 4 groups on the basis of body weight and were supplemented with either basal diet i.e. Concentrate mixture and finger millet (Eleusine corocana) straw @ 50: 50 ratio (BD) which was considered as Negative control (NC), BD with 50 mg/kg zinc from inorganic ZnO (IZn-50), BD with 50 mg/kg zinc from NZnO (NZn-50) or BD with 25 mg/kg zinc from NZnO (NZn-25) for about 4 months. Supplementation of zinc from either inorganic or nano Zn had no effect (P>0.05) on RBC (106/ µl), WBC(103/ µl), PCV (%), neutrophil (%), lymphocytes (%), eisonophil (%), monocyte (%), haemoglobin (g/dL), ALT (IU/L), AST (IU/L), ALP (IU/L) and creatinine (mg/DL) levels of goat blood. However, globulin (g/dL) and total protein (g/dL) varied significantly among the treatment groups (P<0.01) without affecting blood albumin (g/dL) and A/G ratio levels (P>0.05). The globulin level was more (P<0.01) in NZn-50 compared to both NC and IZn-50. Total protein (g/dL) was more (P<0.001) in NZn-50 which varied significantly with NZn-25 and NC, but non-significantly with IZn-50 (6.87±0.01). Hence, zinc supplementation in form of nano zinc improved globulin and total protein significantly without affecting other haematological and blood biochemical parameters in goats, which may be attributed to its better bioavailability than its inorganic counterpart.
