Effect of the Biologically Produced Nanoselenium Dietary Supplementation on Growth Performance, Carcass Characteristics, Blood Parameters, and Economic Efficiency in Broiler Chickens

Abstract

This study evaluates the impacts of the produced nano selenium (SeNPs) products using lactic acid bacteria (LAB) as substitutional to the imported commercial organic selenium (Sel-Plex) as a source of Se dietary supplement on growth performance, carcass characteristics, blood parameters, and economic efficiency in Cobb500 broiler. Four hundred and eighty-one‐day‐old mixed‐sex Cobb500 broilers were reared until 35-days of age and randomly assigned to one of three treatment groups, each with four replicates (40 birds per replicate). Chicks in the control group were fed commercial diets. The chicks in the second and third groups were fed control diets supplemented with 0.3 mg/kg of either nano selenium (SeNPs) product or commercial organic selenium (Sel-Plex). Chicks fed a diet containing nano selenium diet (SeNPs) recorded significantly the highest final body weight, while those fed the control diet recorded significantly the lowest final body weight (2132.2 vs. 1996.1 g, p < 0.05). Chicks fed SeNPs diet had a higher significant breast muscle percentage, while no significant differences could be observed between those fed the control and the Sel-Plex diets. Plasma total protein, albumin, globulin, A/G ratio, and total lipids did not significantly different due to selenium source in diets. There were no substantial effects on all hematological parameters by nano or organic selenium compared to the control diet. In conclusion, feeding broiler chicks with 0.3 mg biological nano selenium (SeNPs) form/ kg diets enhanced growth performance and had no adverse effect on carcass markers and blood parameters.
