Description

Technical Field

[0001] The invention relates to the technical field of pet food, in particular to a baked cat food for improving the immunity of young cats. Background Art

[0002] Kittens rely on maternal antibodies in breast milk for protection in the first few weeks after birth, but this protection gradually weakens as they grow, and the immune system needs time to fully develop. During this period, kittens are vulnerable to external viruses and bacteria. Kittens enter an immune blank period 4-12 weeks after birth. At this time, the level of maternal antibodies decreases, and their own antibodies have not yet formed, making kittens extremely susceptible to diseases. Kittens grow and develop rapidly between 2 weeks and 5 months of age and require high nutritional support. At the same time, improving immunity is crucial to their healthy growth. A kitten's immunity is directly related to whether it can successfully pass the immune blank period and whether it can grow up healthily.

[0003] Currently, cat food on the market is filled with a large amount of starchy plant materials. These ingredients are not easily absorbed by the intestines of kittens. Although some cat food has added probiotics to improve the intestinal digestive function of kittens, it ignores the need for additional immune support for kittens during the immune blank period.

The experimental methods in the following examples that do not specify specific conditions are usually measured according to national standards. If there is no corresponding national standard, then the conditions recommended by the manufacturer are followed.

[0056] In order to verify the effect of the cat food prepared by this method, the following experiments were conducted:

[0057] The cat food prepared in the above embodiment and the commercially available juvenile cat food were used to feed pet cats under the same conditions. 16 young cats with similar weight and good health were randomly divided into 2 groups, with 8 replicates in each group and 1 cat in each replicate. Before the test, the 16 young cats were subjected to necessary immunization and deworming treatment. The experimental group was fed with the cat food prepared in this embodiment, and the control group was fed with commercially available juvenile cat food. The preliminary test period was 7 days and the formal test period was 60 days. After feeding for 30 days and 60 days respectively, immunoglobulin A, immunoglobulin G, immunoglobulin E and interleukin 6 in the blood of pet cats were detected by chemiluminescent immunoassay. 5 mL of venous blood was collected on an empty stomach in the early morning and in a quiet state, and injected into a vacuum blood collection tube without anticoagulant. Serum without hemolysis was separated within 2 hours after blood collection, and at least 1.5 mL was drawn. The chemiluminescent immunoassay was used to complete the test within 8 hours after blood collection. The test results are as follows;

[0058] Table 1:

[0059]

[0060]

[0061]

[0062] Table 1 shows the test results of blood routine indicators of pet cats

[0063] According to the test results of Table 1, the test group cats eating the cat food of the present invention and the control group cats eating ordinary cat food were subjected to routine blood tests. After feeding for 30 days, the leukocyte classification counts of the test group cats showed beneficial changes. Among them, the lymphocyte ratio showed a moderate upward trend, which indicated that the number of specific immune cells of the cat increased and the cellular immune function of the immune system was strengthened. At the same time, the activity and number of neutrophils remained at a stable and healthy level, which helped the cat to resist the invasion of pathogens such as bacteria and maintain the immune balance of the body. In addition, the red blood cell and platelet-related indicators also remained normal and stable, and there was no abnormal fluctuation caused by the immune regulation process, indicating that the cat food of the present invention would not adversely affect the overall function of the blood system of the cat while improving immunity. After the test group kittens were fed the cat food prepared in the embodiment, the lymphocyte ratio increased moderately when the total leukocyte count did not increase abnormally, indicating that the specific immune function of the test group kittens was improving.

[0066]

[0067] Table 2 shows the test results of pet cat blood biochemical indicators

[0068] According to the test results in Table 2, no statistically significant differences were found in the blood biochemical indexes of kittens in the control group and the experimental group (P>0.05).

[0069] Table 3:

[0070]

[0071]

[0072] Table 3 shows the test results of serum immune indexes of pet cats

[0073] According to the test results of Table 3, the serum immunoglobulin test results show that the IgA, IgG and IgM levels of the test group cats that eat the cat food of the present invention are significantly increased. The increase of IgA shows that the mucosal immunity of the cat is enhanced, and a more effective immune barrier is formed in the mucosal parts such as the respiratory tract and gastrointestinal tract, which can better prevent the adhesion and invasion of pathogens and reduce the risk of infectious diseases. As an important indicator of humoral immunity, the significant increase in the level of IgG means that the overall humoral immune response ability of the cat is enhanced, and viruses and bacterial toxins can be neutralized more effectively, and pathogens can be removed by activating the complement system and other methods, thereby enhancing resistance to a variety of diseases. The increase of IgM reflects that the cat food stimulates the primary immune response ability of the cat, so that the body can react quickly when contacting new antigens, and produce enough IgM to control the early spread of pathogens, which buys time and lays the foundation for subsequent immune defense.

[0074] In summary, according to the test results of blood routine and serum immune indexes, the cat food designed by the present invention has significant and effective effects in improving the immunity of cats. By regulating multiple links of cellular immunity and humoral immunity of the immune system, as well as enhancing mucosal immunity, the cat food can help cats better cope with the challenges of external pathogens, maintain a healthy immune state, and reduce the incidence of diseases. It has broad market application prospects and practical breeding value, and provides an innovative and reliable solution for the healthy breeding of pet cats.
