Abstract

The experiment was realized with 330 ISA Brown laying hens divided into 11 treatments with 3 replicates in each treatment. Selenomethionine (SM) or selenite (SS) was used as a dietary supplement of 0.3 mg selenium (Se) in experimental treatments. Vitamin E (E) was added simultaneously in graded amount from 0 to 625 mg/kg. Selenium supplement, especially SM, increased Se concentration in egg yolk and albumen. Linear growth of E in accordance with its dietary content was recorded in eggs. Selenomethionine significantly increased E in yolk. Cholesterol in eggs was reduced at 119 mg of α-tocopherol and SM in diet. The effect of E on decline of TBARS forming was relatively small.
