Effects of Hot Melt Processed Nano Iron on Growth Performance, Digestibility and Blood Biochemical Profile in Weanling Pig

The objective of this study was to investigate the influence of dietary nano-Fe on growth performance, nutrient utilization and blood biochemical profile in grower pigs. An experiment was conducted considering twenty four (N=24) weaned pigs of HDK-75 having average body weight 21.50±0.38 kg selected from AICRP pig farm, and allotted into four treatment groups. The treatment groups were T0 (Control), T1 (100mg inorganic iron), T2 (75mg organic iron) and T3 (50mg nano iron). Results of 90 day feeding trial showed that there was significant difference (P<0.05) found in body weight gain and average fortnightly body weight change, which was observed from 75th to 90th day. However, FCR existed significant difference (P<0.05) from 60th to 90th day among the different treatment groups. The feed intake and digestibility of nutrient was not showing any significant affect except NFE digestibility which was significantly (P<0.05) higher in T3 group. In blood biochemical parameters, serum protein and serum iron was found significantly (P<0.05) higher in T3 group and there was no significant difference (P>0.05) observed for blood glucose, albumin, globulin, A:G, AST, ALT and BUN. So, it can be suggested that supplementation of nano-Fe @50mg per kg of diet improves overall growth performance, nutrients digestibility and hematological profile to the experimental pig to prevent the occurrence of piglet anaemia.
