Objective:To study the effects of bee pollen on anti-oxidation function in hybrid broilers.Methods:272 one-day-old hybrid broilers(COBB 1500 ♂× HISEX ♀) were randomly divided into 4 groups

there were 68 broilers(34 cocks and 34 hens) every group.GroupⅠ was the contrast group;groups Ⅱ

Ⅲ

Ⅳ were treatment groups

with 0.5%

1.0%

1.5% bee pollen respectively.At 14

28

42days old

8 broilers were randomly selected every group

blood serum were collected to determinate the activity of SOD

CAT and GSH-Px

and the content of MDA.Results: Added bee pollen at different doses had significantly(P<0.05

P<0.01) increased the activity of SOD

CAT and GSH-Px

and decreased the content of MDA in serum of hybrid broilers.Conclusions: By adding bee pollen

free radical was scarenged effectively

the production of lipid over oxide was decreased

and the activity of anti-oxidase was improved.
