Description

Technical Field

[0001] This invention belongs to the field of pet food technology, specifically relating to a pet snack with joint protection function and its preparation method. Background Technology

[0002] Pet arthritis is a chronic, systemic, inflammatory disease in dogs, cats, and other pets, primarily affecting the movable joints of the limbs. Clinical manifestations include swelling or lameness in the wrist, knee, and hock joints, as well as edema, heat, and fluctuation in the surrounding soft tissues. The incidence increases with age, and symptoms become more pronounced. Additionally, obesity, excessive running and jumping, and congenital hip dysplasia in some canine breeds can also lead to arthritis.

[0003] Drug therapy is one of the most common methods for treating arthritis in pets. Commonly used drugs include nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and antibiotics. While these drugs are quite effective, they also have significant side effects. For example, NSAIDs, while providing antipyretic and analgesic effects, can also damage the gastrointestinal mucosa, manifesting as pinpoint bleeding, diffuse superficial mucosal erosion, and may even lead to local ulcers, massive bleeding, or perforation. Furthermore, adverse reactions can occur in the liver, nervous system, urinary system, blood system, and cardiovascular system. Moreover, drug therapy is only effective if the pet already exhibits arthritis symptoms; it cannot prevent arthritis. Therefore, it is necessary to develop a video program to prevent and treat arthritis in pets, aiming to address the issue through daily care and feeding habits. Summary of the Invention

[0004] The present invention aims to provide a pet treat with joint protection function to solve the problem that drug treatment has significant side effects and cannot prevent arthritis in pets.

[0005] To achieve the above objectives, the present invention provides a pet snack with joint protection function, comprising the following components by weight: 40-55 parts starch, 20-25 parts meat, 15-20 parts rice flour, 5-10 parts pea protein, 4-5 parts glycerin, 1-2 parts fish oil, 0.1-0.2 parts potassium sorbate, 0.1-0.2 parts calcium propionate, 0.03-0.05 parts vitamin C, 0.01-0.03 parts rosemary extract, 0.01-0.03 parts sunset yellow, 0.01-0.03 parts caramel color, 0.2-0.5 parts eggshell membrane powder, 0.01-0.05 parts curcumin, and 10-20 parts water.

[0006] The working principle and beneficial effects of this treatment are as follows: Eggshell membrane powder contains chondroitin sulfate, hyaluronic acid, and glycosaminoglycans, which can reduce the expression of pro-inflammatory cytokines, thereby alleviating joint pain, repairing joint damage, and improving joint function in pets. Furthermore, curcumin can inhibit oxidative enzymes and scavenge free radicals, thus preventing the occurrence and development of osteoarthritis. Therefore, this treatment combines eggshell membrane powder with curcumin to fully leverage their synergistic effect, significantly reducing prostaglandin E2 levels, alleviating joint inflammation, thereby reducing joint pain, promoting articular cartilage repair, and improving joint function. Moreover, no adverse reactions such as gastrointestinal discomfort or diarrhea were observed after feeding the pet treats in this treatment to pets.

[0007] Optionally, the raw materials, by weight, include the following components: 45 parts starch, 20 parts meat, 15 parts rice flour, 8 parts pea protein, 4 parts glycerin, 1 part fish oil, 0.1 part potassium sorbate, 0.1 part calcium propionate, 0.03 parts vitamin C, 0.01 part rosemary extract, 0.01 part sunset yellow, 0.01 part caramel color, 0.5 parts eggshell membrane powder, 0.05 parts curcumin, and 20 parts water. Pet treats containing the above components show excellent therapeutic effects on pet arthritis.

[0008] Optionally, the starch is one or more of corn starch, sweet potato starch, wheat starch, cassava starch, and potato starch.

[0009] Optionally, the meat is one or more of chicken, beef, duck, pork and mutton.

[0010] This invention also provides a method for preparing pet treats with joint protection function, comprising the following steps:

[0011] S1. Weigh out all raw materials and set aside.

[0060] Application examples

[0061] Dogs with joint inflammation were recruited, and three professional veterinarians assessed their joint mobility using the criteria shown in Table 1. The dogs were randomly divided into seven groups of five, and each group was fed the pet treats described in Examples 1-4 and Comparative Examples 1-3. The daily feeding standard was 120g of staple food + 30g of treats, twice daily. After eight weeks of feeding, the joint mobility was assessed again by three professional veterinarians, and the results are shown in Table 2.

[0062] In addition, the prostaglandin E2 levels of each group of dogs were measured before feeding them pet treats. After eight weeks of feeding, the prostaglandin E2 levels of each group of dogs were measured again. Specifically, the PGE2 content in the canine blood serum was measured using a canine prostaglandin E2 (PGE2) ELISA kit (Shanghai Ruifan Biotechnology Co., Ltd.). The results are shown in Table 3.

[0063] Table 1. Joint Range of Motion Scoring Criteria

[0064] 1 point Full range of motion 2 points The range of motion is slightly limited (10-20%); there is no crepitus during joint movement. 3 points The range of motion is slightly limited (10-20%); crepitus is heard during joint movement. 4 points Moderately limited range of motion (20-50%); crepitus is heard during joint movement. 5 points Range of motion is severely limited (>50%); crepitus is heard during joint movement.

[0065] Table 2 Joint range of motion scoring results

[0066]

[0067]

[0068] Table 3. Results of prostaglandin E2 assay

[0069]

[0070] In Tables 2 and 3, "0 weeks" refers to the time before feeding the pet treats of this invention.

[0071] As shown in Table 2, Examples 1-4 all significantly reduced the joint mobility scores of dogs, indicating that the pet treats of this invention can improve pet joint function. Furthermore, the joint mobility score of dogs in Example 1 was 1.6, while the joint mobility scores of dogs in Comparative Examples 2 and 3 were both 2.8. This fully demonstrates that the combined use of eggshell membrane powder and curcumin is more effective in improving pet joint function compared to using eggshell membrane powder alone or curcumin alone.

[0072] As shown in Table 3, Examples 1-4 all significantly reduced prostaglandin E2 levels in dogs, indicating that the pet treat of this invention can alleviate joint pain in pets. Furthermore, the dogs in Example 1 showed a 59.2% reduction in prostaglandin E2 levels, the dogs in Comparative Example 2 showed a 23.8% reduction, and the dogs in Comparative Example 3 showed a 30.5% reduction. This clearly demonstrates that the combined use of eggshell membrane powder and curcumin is more effective in reducing prostaglandin E2 levels in pets compared to using eggshell membrane powder alone or curcumin alone.

[0073] In summary, this invention, by combining eggshell membrane powder with curcumin, can significantly improve joint function in pets and significantly reduce prostaglandin E2 levels, thereby alleviating joint inflammation and pain. Furthermore, no adverse reactions such as gastrointestinal discomfort or diarrhea were observed in dogs during the feeding process.
