[0017] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the following description of the embodiments will be briefly introduced. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Wherein: Figure 1 This is a schematic diagram of the preparation method provided by the present invention. Detailed Implementation

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0021] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0022] Reference Figure 1 The present invention provides an embodiment, specifically a functional pet nutritional supplement and pet food, which is composed of the following components by weight percentage: Table 1: Pet Nutritional Food Formula Ratio Preferably, BHA / BHT can be completely or partially replaced by tocopherol, with the replacement ratio calculated at an antioxidant equivalent of 1:1.5 (i.e., 1 part of BHA / BHT can be replaced by 1.5 parts of tocopherol).

[0023] Preferably, the beef liver pieces are irregularly shaped, 1-2 cm in size, preserving the original tissue structure of the animal liver; the chicken breast strips are strips 0.5-1 cm wide and 2-3 cm long. This shape retains visible meat fibers even after high-temperature sterilization, significantly enhancing the pet's chewing desire.

[0024] Preferably, the herbal extract mixture is prepared by spray drying the following parts by weight of herbal raw materials after water or alcohol extraction: Poria cocos 15-25 parts, Dioscorea opposita 15-25 parts, Populus tomentosa florets 25-35 parts, Atractylodes macrocephala 10-20 parts, and Pogostemon cablin 10-20 parts. The significance of the critical values: When Poria cocos is below 15 parts, its spleen-strengthening and dampness-removing effects are weakened; above 25 parts, it may cause dry mouth. When Populus tomentosa florets is below 25 parts, its anti-inflammatory effect is not obvious; above 35 parts, the bitterness is too strong, affecting palatability.

[0025] Preferably, the probiotic mixture contains Bifidobacterium animalis, Lactobacillus, Bacillus coagulans, and Lactobacillus plantarum, with a total viable count ≥ 100 billion CFU / g at the time of addition; and the finished product has a viable count within its shelf life. The combination of four strains exhibits a synergistic colonization effect, effectively resisting gastric acid and bile salts.

[0026] The preparation method includes the following steps: (1) Raw material pretreatment: Wash the beef liver pieces and chicken breast strips separately. Cut the beef liver into 1-2cm pieces and the chicken breast into strips. Boil them separately in boiling water for 15-20 minutes until cooked (center temperature ≥75℃), then remove and drain for later use.

[0027] (2) Grain gelatinization: Mix rice flour, corn and rice in proportion, add 1.5 to 2 times the weight of water, boil and keep simmering for 20 to 30 minutes until completely gelatinized (starch gelatinization degree ≥90%), to obtain grain paste.

[0028] (3) Fruit and vegetable mixing: Add pumpkin puree, small pieces of carrot and egg yolk powder to the cereal paste in step (2) and mix well.

[0029] (4) Oil phase preparation: Heat chicken oil and fish oil to 60-70℃ (preferably 65℃), add amino acid and mineral premix, vitamin and antioxidant premix, preservative and acidity regulator, and stir until completely dissolved. The premix is ​​not easy to disperse when the temperature is below 60℃; when the temperature is above 70℃, heat-sensitive components such as vitamin B1 and B12 begin to degrade.

[0030] (5) Mixing: Add the cooked beef liver chunks, cooked chicken breast strips, mixture from step (3), oil phase mixture from step (4), Chinese herbal extract mixture, and probiotic mixture to a mixer in sequence, stir for 10 to 15 minutes, and then add chicken broth to adjust to a suitable consistency (viscosity 3000 to 5000 cP, 25℃).

[0031] (6) Filling and sterilization: Fill the mixture into a sealed container (tin can or high-barrier retort pouch), seal it, and sterilize it with high-pressure steam at 121°C for 15-30 minutes (preferably 20 minutes). Cool it to room temperature to obtain the final product. Sterilization time of less than 15 minutes cannot guarantee commercial sterility; sterilization time of more than 30 minutes will result in tough meat and increased nutrient loss.

[0032] Example 1: The following components were weighed according to their respective weight percentages: 12.00% beef liver chunks, 24.70% chicken breast strips, 39.94% cooked rice flour / corn / rice mixture, 0.50% chicken oil, 0.50% fish oil, 3.00% pumpkin puree, 1.50% chopped carrots, 5.00% egg yolk powder, 5.00% mixture of traditional Chinese medicine extracts (20 parts Poria cocos, 20 parts Dioscorea opposita, 30 parts poplar flowers, 15 parts Atractylodes macrocephala, 15 parts Pogostemon cablin), 0.80% amino acid and mineral premix (containing 0.01% methionine, 0.005% potassium chloride, 0.001% copper sulfate, 0.001% zinc gluconate, 0.005% choline chloride, and 0.30% calcium carbonate), and 0.80% vitamin and antioxidant premix (containing 0.003% VB1, 0.003% VB2, 0.002% VB6, and 0.002% VB12). 0.00001%, taurine 0.01%, tocopherol 0.50%, vitamin E 0.05%, ascorbic acid 0.30%), probiotic mixture 0.0005% (live bacteria count) ), potassium sorbate 0.20%, sodium benzoate 0.20%, citric acid 0.10%, BHA / BHT 0.10%, chicken broth to make up to 100%.

[0033] The preparation method is the same as the steps described above. The resulting product is a semi-solid wet food with a moisture content of approximately 72%, protein ≥12%, and fat ≥5%, suitable for dogs and cats of all ages.

[0034] Example 2: The mixture of Chinese herbal extracts was adjusted to 3.00% (Poria cocos 15 parts, Dioscorea opposita 15 parts, Populus tomentosa 25 parts, Atractylodes macrocephala 10 parts, Pogostemon cablin 10 parts), with the remaining components the same as in Example 1. This formula is suitable for young pets or pets with sensitive stomachs for daily health maintenance.

[0035] Example 3: Chicken breast strips were adjusted to 28.00%, the rice flour / corn / cooked rice mixture was adjusted accordingly to 35.94%, and beef liver chunks remained at 12%, with the rest the same as in Example 1. This formula has a crude protein content ≥16% and is suitable for high-exercise dog breeds (working dogs, show dogs). Example 4 (Natural Antioxidant Alternative Formula) Example 4: Replace 0.10% BHA / BHT with 0.15% tocopherol, the rest is the same as in Example 1. This formulation meets the requirement of "no artificial additives".

[0036] Comparative Example 1 (without Chinese herbal extracts) Except for the absence of the herbal extract mixture, the other components were the same as in Example 1. This comparative example was used to verify the immunomodulatory effects of the herbal extract.

[0037] Comparative Example 2 (Ferrous sulfate instead of beef liver) The 12% beef liver chunks were replaced with 0.02% ferrous sulfate (equal iron content) and 12% chicken liver powder, with the rest remaining the same as in Example 1. This comparative example was used to compare the effects and palatability of natural heme iron and chemical iron supplements.

[0038] Efficacy validation data (anemic mouse model) Experimental Methods: Male C57BL / 6J mice, 4 weeks old, were used to establish an anemia model (HGB < 100 g / L) by a combination of a low-iron diet and exsanguination (0.2 mL of blood was expelled from each mouse per week for 4 consecutive weeks). After successful modeling, the mice were randomly divided into 6 groups of 6 mice each: normal control group (normal diet + purified water), model control group (low-iron diet + purified water), ferrous sulfate group (2 mg / kg), Example 1 group, Comparative Example 1 group (no traditional Chinese medicine), and Comparative Example 2 group (ferrous sulfate substitution). The mice were administered the medication by gavage for 28 consecutive days, and blood samples were collected to detect complete blood count and inflammatory markers.

[0039] Table 2 Experimental Comparison Statistical conclusions: Compared with the model control group, the RBC count in Example 1 group increased by 63% (p<0.001), HGB increased by 95% (p<0.001), and IL-6 decreased by 39% (p<0.001). Compared with the ferrous sulfate group, the RBC count in Example 1 group was significantly higher (15.1 vs 12.0, p<0.01), and the palatability was significantly better (92% vs 67%). Compared with Comparative Example 1 group, IL-6, IgG, and IgM were all significantly lower in Example 1 group, demonstrating the immunomodulatory effect of the traditional Chinese medicine extract. Compared with Comparative Example 2 group, the RBC count in Example 1 group was higher and the palatability was better, demonstrating that natural beef liver is superior to chemical iron supplements.
