Production Performance, Hematology And Serum Biochemistry Of Commercial Broilers Supplemented With Nano Selenium And Other Anti-Stressors During Summer

The aim of this study is to determine the effect of dietary supplementation of nano selenium on production performance in commercial broilers during summer stress. Dietary nano selenium was compared with other anti-stressors such as inorganic selenium, Vitamin E, Vitamin C, Betaine and 1% Glutamine. A total of 420 commercial broilers were divided into seven treatments with three replicates of 20 birds each and were supplemented with basal diet (control), inorganic Se (0.30 mg/kg), nano Se (0.15 mg/kg), Vit E (250 mg/kg), Betaine (2g/kg), Glutamine (1%) and Vit C (250 mg/kg). The highest body weight (1945.17 +/- 25.28) and the lowest feed consumption (2973.16 +/- 41.25) with better FCR (1.56 +/- 0.02) was observed in birds supplemented with nano Se than other anti-stressors and control group. It was concluded that supplementation of nano Se in broiler diet improved the productivity of commercial broilers during summer stress.
