EFFECT OF NANO-SELENIUM ON GROWTH PERFORMANCE AND ANTIOXIDANT FUNCTION OF BROILER CHICKEN / 营养学报

ABSTRACT

Objective: 780 Linen yellow broiler chicken, 1 d of age, were used to investigate the effects of nano elemental selenium (Nano-Se) or Na2SeO3 on growth performance and antioxidant function. Method:The chicken were allocated to 13 treatments, each of which had 4 pens of 15 chicks per pen. The thirteen dietary treatments were basal diet only,and basal diet + 0.1、0.2、0.3、0.4、0.5、1.0 mg/kg Se as Na2SeO3 or Nano-Se, respectively. Results:(1) The growth performance of chicken remained steady at the peak value at concentration range of 0.2-0.5 mg/kg for Na2SeO3. Supplementation with 1.0 mg/kg Se as Na2SeO3 reduced (P
