Effect of nano selenium and organic selenium supplementation on some cellular blood parameters of broilers exposed to oxidative stress

الملخص

This study was conducted on (150) birds from one of the commercial crosses of broiler chickens, and it aimed to study the effect of adding different percentages of nano-selenium and organic selenium on some cellular blood parameters in broiler chickens exposed to oxidative stress. Six groups were used, with an average of (25) birds in each group. The study groups were fed a balanced fodder mixture in terms of energy and protein, and the control group G1 ate water only, while hydrogen peroxide was added to the drinking water at a rate of (0.5)%/ liter at the age of 15 days in the G2 group, and the G3 group added nano-selenium at a concentration of (0.07) mg/ kg of feed + hydrogen peroxide in drinking water at a rate of (0.5)% /liter, group G4 added nano-selenium at a concentration of (0.15) mg / kg of feed + hydrogen peroxide in drinking water at a rate of (0.5)% /liter, group G5 added organic selenium at a concentration of (0.07) mg / kg of feed + hydrogen peroxide in drinking water at a rate of (0.5)% /liter, groups G6 added organic selenium at a concentration of (0.15) mg / kg of feed + hydrogen peroxide in drinking water at a rate of (0.5)% /liter. The experiment continued from 15 days old to 45 days . The results of the statistical analysis showed that the addition of nano-selenium and organic selenium in oxidatively stressed broilers led to a significant increase at the level (P ≤ 0.05) in the average hemoglobin concentration in the groups of nano-selenium and organic selenium at the age of 40 days compared with the control group G2. The study also showed a significant increase at the level (P ≤ 0.05) in the average volumetric fraction of red blood cells in the groups of nano-selenium supplementation and organic selenium at the age of 40 days, compared with the control group G2.
