Sažetak
The aim of the research was to determine the effects that organic selenium supplemented in layer diets has on its content in the edible part of egg, on egg freshness and activity of glutathione peroxidase (GSHPx)in hens’ blood. The experiment lasted for 30 days and was completed on 240 laying hens of the Hy Line Brown hybrid. Hens were divided into 2 experimental groups (E1 and E2), each consisting of 120 hens housed in 24 cages. Hens were fed a commercial diet containing 18% of crude protein and 11.60MJ ME/kg. The experiment was set up in two different feeding treatments. The E1 group had diets supplemented with 0.2 ppm of selenium, and E2 had diets with 0.4 ppm of selenium (organic selenium Sel-Plex® ; ; , Alltech, inc.). The GSH-Px activity was higher in blood of hens in the E2 group than in the E1 (P<0.05). Furthermore, statistically the E2 group had a significantly higher portion of selenium in egg yolks and albumen than the E1 group (P<0.05). Analysis of effects that feeding treatments have on egg freshness over three examined periods (fresh eggs, eggs stored for 14 and for 28 days at 4º ; ; C) showed better results for HU (Haugh units) and TBARS (thiobarbituric acid reactive substances) in the E2 eggs than in the E1 eggs.
