[0059] 2. DPPH free radical scavenging ability test

[0060] The in vitro antioxidant capacity of the compound Chinese herbal medicine was determined using the Nanjing Jiancheng DPPH free radical scavenging ability kit (A153-1-1) to measure the DPPH free radical scavenging rate.

[0061] The control group is a group without adding Chinese herbal medicine, and the compound Chinese herbal medicine group is the Chinese herbal medicine in this example that has been fermented and enzymatically hydrolyzed.

[0062] like Figure 1 As shown, the in vitro experimental results showed that the compound Chinese herbal medicine had a good scavenging effect on DPPH free radicals, and the scavenging rate of DPPH free radicals reached 63.7%.

[0063] 3. Determination of total phenolic and reducing sugar content in compound Chinese herbal medicines

[0064] The total phenol content of the plant was determined by referring to the plant total phenol test kit (colorimetric method) (A143-1-1) of Nanjing Jiancheng Bioengineering Research Institute, and the soluble sugar content of the plant was determined by referring to the plant soluble sugar content test kit (colorimetric method) (BC0035) of Nanjing Jiancheng Bioengineering Research Institute.

[0065] The control group is a fermentation medium group without adding the Chinese herbal medicine group, and the compound Chinese herbal medicine group is the Chinese herbal medicine in this example that has been fermented and enzymatically hydrolyzed.

[0066] like Figure 2 As shown, the in vitro experimental results showed that the total phenol content of the compound Chinese herbal medicine reached 14.84μmol / g, and the content of reducing sugar reached 11.33mg / g.

[0067] Comparative Example 1

[0068] Same as Example 1, except that the compound Chinese herbal medicine was replaced with Ligustrum lucidum, and Ligustrum lucidum was fermented with Bacillus subtilis WB800, and a composite probiotic of Lactobacillus plantarum LSJTYHYBBT7 and Bacillus subtilis K12 in a volume ratio of 3:1. The DPPH free radical scavenging rate of Ligustrum lucidum after fermentation (Legen Bio, TO1143) and the total plant phenol content (Nanjing Jiancheng, A143-1-1) were determined.

[0069] The results are as follows Figure 3 As shown, compared with the group fermented with WB800 alone, the DPPH free radical scavenging rate of the compound probiotic fermentation group increased by 20.65%, which was a very significant difference. The total phenol content increased by 9.94 μmol / g. The fermentation effect of the compound probiotic was better than that of the fermentation with WB800 alone.

[0070] Application Example 1:

[0071] 1. Test methods

[0072] In the experiment, 144 blue-grey laying hens aged 420 days (late egg-laying period) were selected and randomly divided into a positive control group and a test group (the compound Chinese herbal medicine group fermented in Example 1), with 6 replicates in each group and 12 laying hens in each replicate.

[0073] The positive control group was fed a basal diet supplemented with 0.25%wt of antioxidant VE, and the experimental group was fed a basal diet supplemented with 0.25%wt of compound Chinese herbal medicine. The basal diet formula and nutritional level of all experimental groups were the same. The basal diet of the experimental chickens used corn, soybean meal, etc. as raw materials, and the nutritional level was based on the Chinese Chicken Feeding Standard (2004). The experimental laying hens were raised in a three-layer ladder cage, and the chickens were vaccinated and the pens were disinfected according to the routine immunization procedures.

[0074] Test method: The chickens were raised by a dedicated person and fed once a day at 7:00. The amount of feed was increased or decreased according to the amount of leftover feed so that the chickens were in a free-feeding state and free-drinking water. The combination of artificial light and natural light was used, and the light was on for 16 hours a day. The number of eggs laid by the test chickens was recorded every day. After 28 days, the chickens were slaughtered and sampled to determine the quality of the test eggs and the serum antioxidant index. Venous blood was collected from the chickens in each group and placed in a test tube without anticoagulant. The blood was naturally coagulated for 30-60 minutes at room temperature. After the blood coagulated, it was centrifuged at 3000rpm / min for 10 minutes. The supernatant was serum, which was stored in a -80℃ refrigerator. The main detection was the changes in the content of reduced glutathione (GSH) and superoxide dismutase (SOD).

[0075] 2. Test results:

[0076] 2.1 Example 1 Effect of the compound Chinese herbal medicine preparation on the egg-laying performance of laying hens

[0077] Results Figure 4 The test results show that the egg production rate of laying hens in the positive control group that has not been fermented and enzymatically treated is about 74%, while the egg production rate of laying hens in the compound Chinese herbal medicine group after fermentation and enzymatic hydrolysis by Lactobacillus plantarum LSJ-TY-HYB-T7 is about 80%, which is significantly higher than that of the control group; especially for the late egg production period, a 6% increase in egg production rate can bring great economic benefits.

[0078] 2.2 Example 1 Effect of the compound Chinese herbal medicine preparation on the antioxidant properties of laying hen serum

[0079] Results Figure 5 The experimental results showed that the compound Chinese herbal preparation can significantly increase the content of reduced glutathione GSH in the serum of laying hens (P < 0.05), and also improve the activity of superoxide dismutase SOD in the serum. Compared with the control group, the activity of serum superoxide dismutase SOD in the experimental group increased by 33.8%. The above results indicate that the compound Chinese herbal preparation can improve the antioxidant capacity of laying hens.

[0080] 2.3 Example 1 Effect of the compound Chinese herbal medicine preparation on the quality of laying eggs

[0081] Egg quality is mainly reflected by yolk color, albumen height, Haugh unit, eggshell thickness, etc. Egg weight is an important indicator for consumers to choose eggs. The heavier the egg weight, the greater the economic benefits. The albumen height can reflect the freshness of the eggs. The Haugh unit is an indicator of the freshness and protein quality of the eggs. The higher the albumen concentration, the fresher the egg and the larger the Haugh unit.

[0082] The test results are shown in Table 1. The test results show that compared with the positive control group, the addition of compound Chinese herbal preparations to laying hen diets can significantly increase egg width and egg weight (P < 0.01), and significantly improve albumen height and Haugh unit (P < 0.05). Adding fermented Chinese herbal preparations significantly increased egg weight, albumen height and Haugh unit, indicating that compound Chinese herbal preparations can improve egg quality, especially improve egg freshness, egg weight and width.

[0083] Table 1 shows the effect of compound Chinese herbal medicine on egg quality

[0084]

[0085]

[0086] Note: * indicates significant difference compared with the control group (P < 0.05), ** indicates extremely significant difference compared with the control group (P < 0.01).
