The aim of this study was to determine effects of liquid supplement of vitamin E and Selenium (Certiselen-E®) on biochemical metabolites composition of laying hens during high environmental temperature. A total number of 144 white Lohman LSL-Lite laying hens at 63 weeks of age divided into 24 cages. Four levels of Certiselen-E supplement including zero (T1 or control), 0.5 (T2), 0.75 (T3) and 1.0 (T4) ml per liter of drinking water with 6 replicates (n=6) were used during 4-week trial period. At the end of experiment blood samples were taken via wing vein from one randomly-selected hen per each replicate and sera stored at -20°C until analysis for glucose, cholesterol, triglycerides (TG), low and high density lipoproteins (LDL and HDL), total protein (TP), albumin and globulin.The general linear model procedure of SAS software was used for data analysis and differences among treatment means determined using the Duncan’s multiple-range test. The results showed that the inclusion of Certiselen-E supplementation had a significant effect on biochemical metabolites composition of laying hens (P<0.05). Adding Certiselen-E to the drinking water significantly decreased serum cholesterol, triglyceride, LDL and increased HDL concentrations (P<0.05).
