The study evaluated the effects of substituting inorganic selenium with organic selenium on broiler chicken’s growth performance. We used 972 male Ross broiler chickens that were randomly distributed in 36 pens with 27 birds each. The birds were fed an ad libitum (at one’s pleasure) corn-soybean diet from one to 43 days of age. The treatments consisted of two main groups, the whole or fractional inorganic sodium selenium (IS) treatments and the organic selenium (OS) produced by Sel-Plex®. Treatment 1 (T1) 0.3 ppm IS; treatment 2 (T2) 0.2 ppm IS + 0,1 ppm OS; treatment 3 (T3) 0.1 ppm IS + 0.2 ppm OS; and treatment 4 (T4) 0.3 ppm OS. At 43 days of age, the broiler body weights were: (T1) 2978 g; (T2) 2981 g; (T3) 3005 g, and (T4) 2981 g while the feed conversion Table were: (T1) 1,888:1; (T2) 1,850:1; (T3) 1,839:1; and (T4) 1,825:1. The total mortality rate were: (T1) 12.75%; (T2) 12.35%; (T3) 10.32% and (T4) 8.86%. The values of the productive efficiency index recorded were: (T1) 322; (T2) 329; (T3) 341 and (T4) 347. The results indicated that the replacement of inorganic selenium for organic did not maximize broiler performance at 43 days of age.
