Abstract

The study examined the effect of dietary supplements of selenium on growth performance, selenium content in breast meat, glutathione peroxidase (GSH-Px) activity of broiler chickens. The experiment was realized with seven hundred thirty five cockerels Ross 308 randomly divided into 7 dietary treatments. Chickens were fed by diet supplemented with 0 (control), 0.15 or 0.30 mg of selenium/kg in the form of sodium selenite (SS), Sel-Plex (SP) and selenium enriched alga Chlorella (SCH). Selenium addition influenced body weight at 21 (P ≤ 0.001) and at 35 (P ≤ 0.05) days of age. The selenium content in breast muscle was increased (P ≤ 0.001). Selenium source and level significantly (P ≤ 0.001) influenced GSH-Px activity in breast meat.
