Objective:To observe the effects of Folium Eucommiae decoction(FED) on anti-oxidation function of hybrid broilers.Methods: 272 one-day-old hybrid broilers were selected and divided into 4 groups randomly in the experiment: Ⅰgroup was the control group and hybrid broilers drank tap water.The Ⅱ～Ⅳ groups were fed with Folium Eucommiae crude drug content in drinking water at 5(low dose)

10(moderate dose) and 15 g·L-1(high dose) respectively.The experiment lasted 6 weeks.At 2

4 and 6 weekend

8 hybrid broilers were randomly selected and the blood was collected from the heart respectively.Activity of the Superoxide Dismutase(SOD)

Catalase(CAT)

Glutathione Peroxidase(GSH-Px)and content of the Maleic Dialdehycle(MDA) in the serum were determinated.Results: Activity of SOD

CAT

GSH-Px in serum of Folium Eucommiae groups were significantly higher than that of the control group(P<0.05 or P<0.01)

and the contents of MDA in serum were significantly lower than that of the control group(P<0.05 or P<0.01).Conclusion: FED could enhance the anti-oxidation function of hybrid broilers and the effects did appear positivly correlation with doses to some extent.
