Abstract:

This study determined the effect of dietary supplementing superfine powder of Chinese medicine on the antioxidant ability of laying hens.A total of 576 Xinyang black feather laying hens at 43 weeks of age were randomly divided into the control,Leonuri Herba (LH),Ligustri Lucidi Fructus (LF),Taraxaci Herba (TH),LH+LF,LH+TH,LF+TH,and LH+LF+TH groups,eight replicates per group and nine hens per replicate.At days 60 and 120 of the trial,the hens were sampled to determine the plasma and liver oxidant-antioxidant indexes,as well as the liver expression of antioxidant-related genes.The results showed that,at day 60 of the trial,compared with the control group,the plasma levels of glutathione peroxidase (GSH-Px) in LF and LH+LF groups increased by 10.48% and 12.06%,respectively (P<0.05);the liver levels of superoxide dismutase (SOD),GSH-Px,and catalase (CAT) and mRNA expression levels of SOD-1 and CAT in LF+TH group increased by 111.76%,141.32%,140.48%,168.00%,and 140.00%,respectively (P<0.05);the liver levels of GSH-Px and CAT and mRNA expression levels of SOD-1,GPX,and CAT in LH+LF+TH group increased by 77.55%,76.19%,211.00%,80.00%,and 169.00%,respectively (P<0.05).Compared with the LH and TH groups,the liver SOD level in LF+TH group increased by 125.00% and 53.19%,respectively (P<0.05).Compared with the LH+TH group,the liver mRNA expression level of SOD-1 in LH+LF group increased by 121.05% (P<0.05).At day 120 of the trial,compared with the control group,the plasma SOD level in LH+LF,LF+TH,and LH+LF+TH groups increased by 22.44%,16.98% and 17.84%,respectively (P<0.05).The liver SOD,GSH-PX,and CAT levels in LH+LF group increased by 38.46%,43.72%,and 36.73%,respectively (P<0.05).The liver SOD and CAT levels in LF+TH group increased by 35.16% and 46.94%,respectively (P<0.05).The liver SOD level in LH+LF+TH group increased by 54.95% (P<0.05).In conclusion,the single or compound superfine powder of LH,LF,and TH could improve the antioxidant ability of laying hens to some extent,among of which the LH+LF,LF+TH,and LH+LF+TH groups present stronger effects.
