Effect Of Codonopsis And Compound Codonopsis On Antioxidation Activity And Production Performance In Laying Hens

Objective: To study the effect of compound codonopsis on antioxidation activity and production performance in laying hens. Methods: The trial is divided into trial one and trial two. Trial 1: 180 Hyline White laying hens, aged 24 weeks, were allotted to 6 groups randomly, 30 for each group (group 1 is codonpsis, group 2 is astragali, group 3 is eplmedlum, group 4 is isatidis, group 5 is codonpsis decoction, group 6 is blank). The Chinese medicines were increased the comparison to 1%. The experiment lasted for three weeks. The activities of SOD, GSH-Px and the content of MDA were determined. Data of production performance were recorded. Trial 2: To consult data of trial 1, five Compound codonopsis were made (Compound Codonopsis 1~5). 180 Hyline White laying hens, aged 24 weeks, were allotted to 6 groups randomly, 30 for each group (group 1~5 is Compound codonopsis 1~5, group 6 is blank). Group 1~5 were as the experimental group which were fed the diets containing 1% of the Compound Codonopsis 1~5. The experiment lasted for three weeks. The activity of SOD, the activity of GSH-Px and the content of MDA were determined. Data of production performance were recorded. Results: Trial 1: The activity of T-SOD in serum in RC group were markedly higher than that in control group, increased 30.02% (P<0.01); The activity of GSH-Px in blood in RC group were markedly higher than that in control group, increased 35.44% (P<0.01); The content of MDA in serum in RC group were markedly lower than that in control group, reduced 22.43%; The production performance in RC group were markedly higher than that in control group, increased 11.5% (P<0.05). Trial 2: The activities of T-SOD in Group 4, group 5 were markedly higher than that in control group, increased 30.71%, 38.46% (P<0.01); The activities of GSH-Px in group1,group 4,group 5 were markedly higher than that in control group, increased 10.78% (P<0.05), 14.47% (P<0.05), 26.49% (P<0.01); The content of MDA in group 4, group 5 were markedly lower than that in control group, reduced 27.72% (P<0.01), 31.02% (P<0.01); The production performance in group 4, group 5 were markedly higher than that in control group, increased 11.01% (P<0.05), 13.47% (P<0.05). Conclusion: This study shows that the antioxidation activity and production performance may be increased by the compound codonopsis preparation in laying hens.
