I. INTRODUCTION The role of Se in poultry nutrition has been reviewed extensively (Surai, 2002a,b). Selenium is involved in the control of several physiological functions such as growth and immunocompetence. Se, as a constituent of selenoproteins, has structural and enzymatic roles, which impact on the antioxidant status and thyroid secretion of the bird (Sevcikova et al,. 2006). Also, Se is a c...

What would be the impact of fortifying such formulations with Vitamin E?

Growth performance was very similar across all dietary treatments, in contrast, significant differences in nutrient utilisation were observed. The N-corrected AME value (AMEn) for the negative control (14.14 MJ/kg) and SH (14.15 MJ/kg) diet were significantly higher (P < 0.01) than the SM (13.64 MJ/kg) diet. Alternatively, N retention with the SM (68.4%) diet was significantly higher (P < 0.005) than the control (65.2%) and SH (64.5%) diets

Activity of GSH-Px and SOD increased in plasma,muscle and liver samples of birds received Se supplementation. What are implications which could be derived from these findings? Se supplementation helps to increase the specific activity of each of the two enzymes? or Se induces higher rate of GSH-Px and SOD synthesis? what are the desirable benefits we want to have in these two cases.
If the authors accept the results of their statistical analysis, then they should not try to give the impression that SH appears to be better than SM based on Tables 1,2,and 3. they should simply concluded that Se supplemented at 0.3 mg/kg feed significantly improves antioxidant status in broilers observed at 42 days after hatching

Interesting article, can we use in-ovo inoculation of these selenium supplements in chick embryo?
