Note: the difference in the superscript letters on each column indicates significant difference (P < 0.05).
Immunoglobulin is an animal protein with antibody activity, is converted into an antibody after antigen stimulation, is the same as an immune organ index, and is an important index for measuring the immune function of animals. Wherein IgG is the highest content of immunoglobulin in serum, accounts for 75 percent, and is the main antibody generated by animals after natural infection and artificial active immunization; IgM is a high-performance antibody, the content of which is only second to that of IgG, and accounts for 10-12% of total serum Ig, and the IgM has strong bactericidal, bacteriolytic and agglutination effects. As can be seen from Table 6, compared with the blank control group, the positive control group (0.5 g/kg of Scutellaria baicalensis Georgi extract) has the advantages that the immunoglobulin IgG is remarkably increased, and the IgM is improved to a certain extent, so that the positive control group (0.5 g/kg of Scutellaria baicalensis Georgi extract) can improve the immunity of the broiler chicken. Observing the traditional Chinese medicine compound groups, the traditional Chinese medicine compound groups 1 and 2 can obviously improve the IgG level of the broiler chickens, the traditional Chinese medicine compound group 3 can greatly improve the IgG level of the broiler chickens, and similar results are reflected on immunoglobulin IgM, so that the traditional Chinese medicine compound groups can improve the immune function of organisms as same as a positive control group, and the traditional Chinese medicine compound groups have certain dosage tolerance, and the larger the dosage is, the more obvious the improvement effect is. In combination, IgG and IgM were equally or more quantitatively identical to or superior to that of the positive control group (Scutellaria baicalensis Georgi extract 0.5g/kg) starting from the traditional Chinese medicine compound group 2(3 g/kg).

Note: differences in the superscript letter on each column indicate significant differences (P < 0.05).
T-AOC is used for evaluating the total antioxidant level formed by antioxidant substances, antioxidant enzymes and the like of the body; MDA is one of the most important products of membrane lipid peroxidation, and the damage of the membrane can be aggravated by the generation of MDA, and the degree of membrane lipid peroxidation is commonly known by the MDA. As shown in Table 7, compared with the blank control group, the total antioxidant capacity of each group of the Chinese herbal compound is higher than that of the blank control group, and the total antioxidant capacity of the group 3(5g/kg) of the Chinese herbal compound is significantly higher than that of the positive control group (P < 0.05). MDA of a positive control group (0.5 g/kg of the extract of the scutellaria baicalensis of the mountain flower) has a tendency of reducing, and the positive control group can reduce the oxidative damage of the oxidized oil to the organism or enhance the endogenous antioxidant capacity of the organism to a certain extent; MDA of each group of the traditional Chinese medicine compound also shows a descending trend, wherein the traditional Chinese medicine compound group 2(3g/kg) and the traditional Chinese medicine compound group 3(5g/kg) are remarkably reduced compared with a blank control group (P is less than 0.05). The results of T-AOC and MDA jointly show that the oxidation resistance of the traditional Chinese medicine compound group 2(3g/kg) and the traditional Chinese medicine compound group 3(5g/kg) is equal to or better than that of a positive control group (0.5 g/kg of the extract of the scutellaria baicalensis of the mountain flower).
In conclusion, the performance of the broiler experimental group eating the feed added with the traditional Chinese medicine compound in the aspects of average daily gain, total-period average body weight, material-to-weight ratio, spleen index, bursal index, thymus index, immunoglobulin IgG/IgM, antioxidant capacity and the like is superior to or equal to that of the broiler control group eating the feed added with the positive medicine (0.5 g/kg of the scutellaria baicalensis extract), and the traditional Chinese medicine compound does not contain antibiotics, does not cause drug resistance, does not expose a large amount of livestock and poultry and even human beings to infection danger caused by drug-resistant strains, the traditional Chinese medicine compound group 2(3g/kg) and the traditional Chinese medicine compound group 3(5g/kg) are equal to or superior to the positive control drug, namely the extract of the radix scutellariae barbatae, on the whole, so that more choices can be provided for clinical medication, and a new thought is provided for a non-resistance, green and healthy breeding mode.
In addition, through multiple experiments of the inventor, the inventor finds that the raw materials of the traditional Chinese medicine compound are weighed according to 20g of callicarpa nudiflora, 10g of purslane, 10g of houttuynia cordata, 10g of pogostemon cablin, 10g of mint, 8g of furnace soil and 8g of plant soot, and under the condition that the total compound dosage is the same, the influence of small change of the dosage of each medicine on the experimental result is very small, so the embodiment of the invention is described in detail as the experimental results of 16-24 g of callicarpa nudiflora, 8-12 g of purslane, 8-12 g of houttuynia cordata, 8-12 g of pogostemon cablin, 8-12 g of furnace soil, 7-9 g of furnace soil and 7-9 g of plant soot, and through dosage screening, the traditional Chinese medicine compound is considered to be uniformly mixed with feed according to 3g/kg, and the cost ratio of the medicines can be exerted to the maximum.
