Effect of nano zinc supplementation on serum biochemical and mineral levels in Malabari kids fed on complete rations with varying energy levels

A study was conducted to assess the effect of dietary supplementation of nano zinc oxide (Zn) on mineral retention and serum mineral levels of Malabari kids. Fifteen Malabari kids of 2-3 months of age were randomly allotted to three dietary treatments with five replicates in each. The dietary treatments were: T1 (Control)- Complete feed containing CP- 14%, TDN- 70%, T2- Complete feed containing CP-14%, TDN- 65% with supplementation of 20 ppm nano zinc, T3 – Complete feed containing CP- 14%, TDN- 60% with supplementation of 20 ppm nano zinc for a period of 90 days. Blood was collected subjected to assess serum mineral status and serum biochemical analysis at end of trial. Serum zinc levels were significantly higher (p0.05) on haemoglobin (g/dL), serum glucose, total protein, globulin and serum enzymes like ALT (IU/L), AST (IU/L), ALP (IU/L) and creatinine (mg/dL) levels. The study concluded that nano zinc supplementation to complete ration having lower energy (60 % TDN or 65 % TDN) in kids did not alter the serum calcium, phosphorous, copper , manganese and serum biochemical parameters while significantly (p
