  To study the comparative effects of Nano Selenium (Nano-Se) and sodium selenite on the growth, bioavailability, antioxidative activities, hematological and biochemical parameters, cellular and humoral immunity, a trial was conducted on BV 300 layer birds during grower phase (9-20 after weeks) in six treated groups. After twenth weeks body weight of the all Nano-Se treated groups (up to a dose of 0.3 mg kg-1 of diet) was found to be significantly (p<0.05) higher than sodium selenite treated and control groups. However, further increase in dietary Nano-Se content in feed had negative effect on body weight of bird. Birds fed with both Nano-Se and sodium selenite showed higher (p<0.05) Se content in different tissues (Such as breast muscle, liver, kidney, pancreas, serum and feathers). However, Se content in liver, breast muscle, pancrease and feathers were signifcantly higher (p<0.05) in Nano-Se treated groups. In addition, significant (p<0.05) difference was observed as regard to glutathione peroxidase (GSH-Px), erythrocyte catalase (CAT) and superoxide dismutase (SOD) activities among the treated groups. Significantly better cellular and humoral immunity response were observed in Se supplemented birds. Dietary supplementation of Nano-Se improved the body weight, feed consumption ratio, antioxidant status, immunity and tissue Se deposition in grower birds.

  Comparative study on the effect of nano selenium (nano-Se) and sodium selenite on the growth, bioavailability, antioxidative activities, hematological and biochemical parameters, cellular and humoral immunity was done in layer chicks upto 8th week post feeding. The results showed significant differences (p<0.05) in relative weight gain and final body weight of the nano-Se treated groups upto a dose of 0.3 mg kg-1 of diet as compared to sodium selenite and control groups. However, further increase in dietary nano-Se content in feed had negative effect on weight and Relative Gain Rate (RGR). Survival rate and Feed Conversion Ratio (FCR) were not affected by dietary treatments. Chicks fed with both nano-Se and sodium selenite showed higher (p<0.05) Se content in different tissues (breast muscle, liver, kidney, pancreas, serum and feathers). However, highest value (p<0.05) of Se content in breast muscle and liver was observed in nano-Se treated groups. Selenium concentrations in serum, liver and breast muscle increased linearly and quadratically (p<0.05) as dietary Se level increased for all Se sources but its magnitude was substantially greater (p<0.05) when nano-Se was fed. Glutathione peroxidase (GSH-Px), erythrocyte catalase (CAT) and superoxide dismutase (SOD) activities were significantly different (p<0.05) in all treated groups than control. Dietary nano-Se also increased several serum biochemical and haematological parameters. In addition, it significantly increased both cellular and humoral immunity in layer chicks after 8th weeks of post feeding. In conclusion, dietary administration of nano-Se was found superior than that of inorganic sodium selenite in various aspects in layer chicks. Further extensive study for exploring absorption mechanisms, metabolic pathways, ideal dose/form of nano-Se is suggested for optimum utilization of nano-material based application of Se feeding in poultry.

  Effect of replacement of inorganic minerals viz., zinc (Zn), copper (Cu) and manganese (Mn) with their corresponding organic minerals (methionine) on growth, bioavailability and immunity was studied in grower birds (9th to 20th week). At 20th week, the body weight of grower birds were significantly (p<0.05) higher in 100% organic Zn group, 100 and 50% organic Zn, Cu and Mn supplemented groups. The cumulative feed consumption and FCR of all the treated groups showed no significant (p>0.05) difference. The serum glucose, after cholesterol SGOT, SGPT and ALP levels differ significantly (p<0.05) of all the treated groups of differed significantly (p<0.05). The CBH response and the antibody titers against SRBC were found to be significantly higher in 100% organic Zn group and 100% Zn, Cu and Mn supplemented groups. Tibia bone weight (g), tibia calcium (%) and tibia phosphorus (%) varied insignificantly (p>0.05). But significant (p<0.05) difference was observed as regard to the tibia ash content. Faecal excretions of Zn, Cu and Mn were significantly lower in organic mineral fed groups. Replacement of inorganic Zn, Cu and Mn with their corresponding organic minerals improved the body weight and immunity, with lower faecal excretion of minerals in grower birds.
