[0002] The pet industry is a new industry. However, with the increasing number of people raising pets, many problems have emerged. One of them is that there is a wide variety of pet feeds, and it is difficult for some pets to absorb them, especially fats and proteins are difficult to digest and absorb, resulting in unpleasant odors in the excrement of pets, polluting the environment and affecting home life. The second is that the hair quality and color of pets are important indicators of pet breeds and aesthetics. However, due to reasons such as feeding, living environment, and the living habits of pet owners, problems such as hair loss, fading, and coarsening of pet hair have also become prominent. The third is that pets are affected by the environment and other factors, with low immunity and disease resistance, and often suffer from some common diseases.

[0041] S2. Sequentially add 30 kg of chicken powder, 15 kg of salmon powder, 5 kg of chicken liver powder, 10 kg of hydrolyzed fish protein powder, 15 kg of sweet potato dry powder, 5 kg of pea fiber, 5 kg of tapioca starch, 9.7 kg of chicken oil, 2 kg of fish oil and 0.5 kg of lecithin to the premix, and stir well to obtain a mixed material;

[0042] S3. Pelletize the mixed material using an extruder. The pelletizing conditions are: conditioning temperature 85 - 90°C; extruder screw speed 300 rpm, die head temperature 120°C, moisture control: moisture content after conditioning ≤ 25 wt%, moisture content after extrusion ≤ 10 wt%;

[0043] S4. Dry the cat food pellets using a fluidized bed. The drying conditions are: hot air at 50°C to reduce the moisture content in the cat food pellets to 8 - 10%, and package with nitrogen replacement to avoid oxidation of nucleotides.

[0044] Example 2:

[0045] 1. Experimental animals and diets

[0046] Select 6 well - developed, similarly - weighted, healthy and lively Garfield cats over 8 months old. The experiment is divided into 2 groups, with 3 cats in each group. Group 1 is the experimental group, fed with the cat food of this patent, and Group 2 is the control group, fed with commercially available cat food.

[0047] 2. Feeding management

[0048] All the test pet cats are raised in the same environment, adopting the same feeding management method, and are raised by a dedicated person. Feed them with the basal diet for 7 days in the pre - experiment to make them adapt to the test diet and feeding environment. Deworm them before the experiment and inject vaccines according to routine immunization. After the pre - experiment, enter the formal experiment with a feeding period of 1 month. Feed three meals a day, breakfast, lunch and dinner. The measurement of the basal diet is not limited, and the principle of feeding is to let them eat enough. Ensure sufficient and clean drinking water. Clean the animal house every day, rinse it once every 2 - 3 days, and disinfect it once a week. Observe the cats' food intake, drinking water, feces color and hair condition every day, and make corresponding records.

[0049] 3. Immune detection method

[0050] On the day when the experiment ended, 5 mL of blood samples were collected from the root of the cat's tail, allowed to stand to separate the serum, and centrifuged at 4000 r / min for 20 min at 4°C to prepare the serum.

[0051] An enzyme-linked immunosorbent assay kit (CUSABIO Co., Ltd., USA) was used to measure the contents of immunoglobulin A (IgA) and immunoglobulin G (IgG), and the measurement was carried out according to the method described in the kit instruction manual.

[0052] 4. Experimental results

[0053] It can be seen from the table that the contents of immunoglobulin A (IgA) and immunoglobulin G (IgG) in the experimental group were increased compared with those in the control group, indicating that the immunity of the experimental group was improved compared with that of the control group.
