Abstract:This experiment was conducted to investigate the effects of Flos lonicerae-Baikal skullcap (FLBS) and Astragalus polysacharin (APS) compatibility use on performance, egg quality, serum antioxidant and biochemical indexes of laying hens. Four hundred and thirty-two healthy Hy-Line Grey laying hens at 43 weeks old were randomly allotted into 4 groups with 6 replicates per group and 18 hens per replicate. Hens in the control group (group Ⅰ) were fed a basal diet, and the others in experimental groups were fed the basal diet supplemented with 100 mg/kg FLBS+100 mg/kg APS (group Ⅱ), 100 mg/kg FLBS+200 mg/kg APS (group Ⅲ) and 100 mg/kg FLBS+400 mg/kg APS (group Ⅳ). The adaptation period lasted for 1 week and the formal period lasted for 12 weeks. The results showed as follows:1) compared with the control group, the indexes of performance and egg quality of laying hens had no significant changes (P>0.05). 2) Compared with the control group, the serum total antioxidant capacity (T-AOC) of groups Ⅲ and Ⅳ at the 6th and 12th weekend of the experiment was significantly increased (P<0.05); at the 12th weekend of the experiment, the serum malondialdehyde (MDA) content of groups Ⅲ and Ⅳ was significantly decreased (P<0.05), the serum superoxide dismutase (SOD) activity of groups Ⅱ, Ⅲ and Ⅳ was significantly increased (P<0.05). 3) Compared with the control group, at the 6th weekend of the experiment, the serum uric acid (UA) content of group Ⅱ was significantly increased (P<0.05), the serum total cholesterol (TC) content of groups Ⅱ and Ⅲ was significantly decreased (P<0.05); at the 12th weekend of the experiment, the serum UA and triglyceride (TG) contents of groups Ⅱ, Ⅲ and Ⅳ were significantly decreased (P<0.05), the serum glucose (GLU) content of groups Ⅱ and Ⅳ was significantly increased (P<0.05). In conclusion, dietary FLBS and APS compatibility use can increase the antioxidant ability of laying hens, also has a certain degree of improvement on lipid metabolism, liver and kidney function. In this experiment, the 100 mg/kg FLBS+100 or 200 mg/kg APS groups have better effects.
