Abstract

SUMMARY The present study was conducted to investigate the effect of feeding flaxseed and 2 types of antioxidants [α-tocopherols (Toc), butylated hydroxy toluene (BHT)] at 3 levels (50, 100, and 150 IU or mg/kg) on production performance, egg quality, fatty acid profile, Toc, and egg cholesterol content. Twenty-four 1-wk-old ISA Brown Leghorn laying hens (n = 96) were kept in cages and were fed a corn- and soybean meal-based diet for 56 d: control (no flax, no antioxidant), 10% flax with no antioxidant, or 10% flax + antioxidants. The flax-based diets had no effect on egg production, egg weight, egg mass, or feed conversion (P > 0.05) when compared with the control diet. Feed intake was reduced in hens fed the flax diets (P 0.05). Lower levels of saturated fat were observed in eggs of hens fed the flax + Toc and flax + 50 mg of BHT diets when compared with hens fed the other diets (P 0.05). Inclusion of Toc led to more than 4.5- to 12-fold increases in Toc in eggs from hens fed flax-based diets. These data demonstrate that eggs with increased n-3 fatty acids and Toc can be produced by minor diet modifications without affecting egg quality parameters.
