Effect of Organic Selenium Dietary Supplementation on Growth Performance, Carcass Retention and Meat Lipid Peroxidation in Broilers

This study was conducted to determine the effect of dietary Selenium (Se) supplementation on growth performance, carcass Se retention and meat lipid peroxidation in commercial broiler chickens.A total of 216 1-day-old male Cobb broiler chicks were randomly divided into 6 groups of 36 chicks each (6 chicks × 6 replications) and assigned to one of the following treatments: (1) a conventional diet as a control (C), (2) C diet supplemented with increasing concentrations (1,2,3,4 or 6mg/kg diet) of organic Se (D1, D2, D3, D4 and D5).Se-supplemented diets were only fed during the grower-finisher phase (d15-d42).
