Abstract:

The experiment was conducted to investigate the effects of dietary flavonoids on the performance, egg quality,The results showed that there was no significant difference in average egg weight and average daily feed intake among the treatments (P>0.05), but PF had tendencies to increase egg production, decrease eggshell broken rate and improve feed efficiency. Yalk cholesterol content was decreased significantly with the addition of PF and DA, to some different extent, PF could decrease yolk MDA level after storage periods of 7 and 14. Dietary DA and PF increased significantly HDL level, decrease TC and TG level at 8th week in serum. 30 mg/kg PF group increased significantly serum insulin level. DA and PF increased significantly T (4, 8 weeks old) and B (8 weeks old) lymphocyte proliferation.

Key words: propolis flavonoids; daidzein; performance; egg quality; serum biochemical property
