Comparison of Different Selenium Sources and Vitamin E in Laying Hen Diet and Their Influences on Egg Selenium and Cholesterol Content, Quality and Oxidative Stability

An experiment was carried out to compare the effects of laying hen’s diet supplemented with inorganic and different organic sources of selenium (Se) on quality and oxidative stability of eggs during storage. A total of 81, (35-week old) laying hens of Lohmann LSL-White were assigned to cages in a completely randomized design with 9 groups of treatment and 3 replicates of 3 birds. Hens in each group were fed their corresponded diet included the basal diet supplemented with sodium selenite, Se-enriched yeast, Cytoplex-selenium and Selenomax at two different levels of 0.3 and 0.6 mg/kg, or 200 mg/kg vitamin E. To prevent brand judgment challenge, A, B and C letters were applied for different organic source of Se. After 56 days of feeding experimental diets, eggs were collected from the hens to analysis. Egg weight loss during storage at 4 ˚C was lower (P
