Description

Technical Field

[0001] This invention relates to a pet coat-enhancing nutritional composition, comprising krill oil, fish oil, and cod liver oil. This composition increases a pet's feed intake and weight gain, improves coat condition, reduces shedding, and enhances coat shine and smoothness. The invention also provides its use in pet food, nutritional formulations, food supplements, beverages, and pharmaceuticals. Another aspect of the invention is a pet food containing this nutritional composition. Background Technology

[0002] Dogs and cats remain the most popular pet types among pet owners. According to the "2022 China Pet Industry White Paper," the number of dogs and cats in urban areas reached 116.55 million, a 3.7% increase compared to 2021, and the urban pet industry market size reached 270.6 billion yuan in 2022. The softness, smoothness, and shine of a pet's fur reflect its health and also affect the relationship between pet and owner. Therefore, improving a pet's fur plays an important role in promoting pet health and enhancing harmony between pets and their owners. According to data from a survey conducted by CBN in April 2021, fur health is one of the most concerning issues for pet owners. Fur is an important organ for humans and animals, second only to bones in importance. Fur plays a crucial role for pets. First, the skin and fur provide a barrier, protecting dogs and cats from external objects, chemicals, and environmental stressors. Second, fur plays a role in thermoregulation; healthy fur helps maintain proper body temperature by providing an insulating layer. In addition, hair has a certain degree of water resistance and can quickly recover after getting wet; the surface of hair also has a waterproof layer, which effectively prevents animals from getting their fur wet when they come into contact with water, helping dogs and cats maintain their body temperature. The physiological structure of hair consists of the hair shaft, which protrudes from the skin, and the hair root, which is embedded in the skin. The hair shaft includes the epidermis, hair tissue, and medulla, possessing strong absorption capacity and resistance to external forces. The hair root is composed of incompletely keratinized epithelial cells and is enclosed by the hair follicle. Hair growth and replacement is a cyclical process, not a continuous one. The growth of each hair follicle is relatively independent; even adjacent hair follicles may be in different stages of the growth cycle at the same time. The hair growth cycle is mainly divided into three different phases: the anagen (growth) phase, the catagen (transitional) phase, and the telogen (resting) phase. Studies have shown that 85%–90% of hair is in the active growth phase. During this period, the dermal papilla grows actively, and the germinal epithelial cells begin to divide; the hair matrix cells in the hair bulb begin to differentiate into various hair follicle components around the dermal papilla, and subsequently, the melanocytes in the hair matrix of the hair bulb are activated; the dermal papilla enlarges, cell division accelerates, and the number of cells increases rapidly. New hair grows out of the skin surface, gradually replacing the hair in the resting phase, and the amount of hair gradually increases and maintains a stable growth state. The regression phase is the transitional stage of hair growth. 1% to 3% of hairs are in this stage. When the mitotic activity of the hair matrix cells gradually weakens and eventually disappears, the hair follicle enters the regression phase. During this period, the hair follicle gradually atrophies, causing the hair to stop growing, and the hair root pushes towards the skin surface, but the hair is still not easily shed at this time. The resting phase is the dormant stage of hair growth, and 10% to 15% of hairs are in this stage. At this time, the hair follicle is dormant, the hair stops growing, and begins to fall out. The hair bulb remains hidden in the epithelial cell sac until the start of the next cycle. As old hairs fall out, new hairs grow from the same follicles, beginning a new growth cycle. The resting phase is a crucial period in the hair growth cycle, maintaining hair density and health.Many factors influence the quality of a dog's or cat's coat, primarily including nutritional, environmental, and feeding / management factors. Basic nutritional intake is essential for healthy coat growth, so paying attention to a healthy and balanced diet is crucial. In daily feeding, pets should be provided with a reasonable and moderate amount of amino acids, minerals, fatty acids, and vitamins to ensure sufficient intake of necessary nutrients for optimal coat growth. An unbalanced diet can lead to insufficient nutrition for hair follicle metabolism, thus affecting coat growth and quality. Among the many causes of pet shedding, besides seasonal shedding and fungal infections, malnutrition-related shedding is also a significant factor. This type of shedding is common during the nursing period, when nutritional needs are high. If the food is of poor quality, the coat will become rough, dry, and dull, becoming thin and brittle, eventually falling out easily and resulting in a reduction in overall coat volume. Once malnutrition has occurred, greater effort is required, not only providing high-quality, fresh food but also supplementing with nutritional supplements.

[0003] Current nutritional regulation methods primarily involve adjusting the proportions of nutrients (minerals, vitamins, fatty acids, amino acids) in pet food or supplementing with nutritional supplements to improve the shine, smoothness, and dryness of a dog's or cat's coat. While fish oil, broadly speaking, includes fish liver oil and other fish fats, its main active ingredients are DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid), which help regulate blood lipids. Although fish oil contains omega-3 fatty acids, it lacks sufficient protein, vitamins, and minerals, and long-term use can lead to nutritional imbalances. Excessive fish oil intake can also cause diarrhea, so dosage should be carefully considered. For dogs and cats, omega-3 fatty acids alone are insufficient; if other nutrients are not adequately provided, the effects of fish oil will be minimal. Furthermore, fish oil has a fishy smell due to the presence of trimethylamine oxide and carbonyl compounds formed by the auto-oxidation of polyunsaturated fatty acids, which dogs and cats dislike.

[0004] Cod liver oil is a fat extracted from the livers of sharks, cod, and other fish. It is yellow, has a fishy smell, and mainly contains vitamins A and D. It is commonly used to prevent and treat night blindness and rickets.

[0005] Krill oil is extracted from krill, an invertebrate, and is rich in omega-3 fatty acids, phospholipids, astaxanthin, choline, and other nutrients. Made from krill through washing, crushing, extraction, concentration, and filtration, krill oil is a dark red or reddish-brown transparent oily liquid. Compared to fish oil, the functional lipids in krill oil make it more nutritious, easier to absorb and utilize, and have a more palatable taste. It is beneficial for promoting human health, offering health benefits to the cardiovascular system, nervous system, bones and joints, vision, and skin.

[0006] Currently, much work has been done both domestically and internationally on applying fish oil to pet coat nutrition, and many of these efforts have resulted in patent applications. For example, CN117814406A discloses a pet food with coat-enhancing effects, whose components, by weight, include: 40-50 parts coat-enhancing ingredients, 20-30 parts fresh bone-in chicken, 10-15 parts fresh chicken breast, 8-15 parts mixed oils, 2-5 parts dried sweet potato, 2-5 parts cassava chips, 1-3 parts additives, 1-3 parts immune-enhancing factors, 0.5-1.5 parts functional additives, and 0.5-1.5 parts natural additives. The mixed oils, by weight percentage, consist of 50-60% chicken oil, 20-30% salmon oil, and 20-30% olive oil. The coat gloss score is 7.95±0.33 on day 0 and 8.11±0.32 on day 90, representing a 6.04% increase in gloss. CN118716526A discloses a cat food that promotes intestinal health and hair care, its preparation method, and its application. The raw materials for preparing the cat food include main ingredients and auxiliary ingredients. The main ingredients include a combination of 35-80 parts poultry meat, 2-20 parts animal offal, 1-10 parts egg yolk powder, 0.5-5 parts fish oil, 1-5 parts psyllium husk powder, 3-8 parts wheatgrass powder, and 2-6 parts chicory root powder. CN108740458A discloses a cat food for preventing hair loss and its preparation method. The cat food comprises the following components in parts by weight: 10-25 parts minced fish; 15-30 parts minced chicken; 1-5 parts seaweed powder; 10-15 parts egg yolk powder; 5-10 parts corn starch; 15-25 parts butter; 8-15 parts salt; 2-5 parts fish bone powder; 2-5 parts cod liver oil; 12-20 parts protein composition; 0.1-1 part Ω-3; 0.1-3 parts Ω-6; 0.01-0.1 parts organic zinc; 5-15 parts polysaccharide composition; 25-50 parts traditional Chinese medicine extract; and 10-18 parts water. US6149932A discloses a food supplement for humans and hairy pets such as dogs and cats, including safflower oil, sunflower seed oil, olive oil, soybean oil, cod liver oil, lecithin, natural flavorings, herbs, garlic, and zinc. US5965153A discloses an animal feed additive composed of safflower oil, sunflower seed oil, olive oil, soybean oil, cod liver oil, lecithin, natural flavorings, herbs, garlic, and zinc. CN118716525A discloses a cat grooming supplement containing 20-45 parts chicken, 20-40 parts salmon, 5-10 parts chicken hearts, 1-3 parts egg yolk, 2.5-5 parts flaxseed oil, 0.5-1.5 parts salmon oil, 0.01-0.10 parts Antarctic krill powder, 0.05-0.10 parts D-biotin, and wt. protein zinc.CN112806484A discloses a pet food that promotes hair growth, comprising the following ingredients: corn starch, soybean meal, beef bone meal, blood meal, egg yolk powder, vegetable meal, meat meal, salt, sucrose, sodium alginate, potassium sorbate, cod liver oil mixture, arginine, and lysine; CN112806484A also discloses a pet food that promotes hair growth, comprising the following ingredients by weight: 15-45 parts corn starch, 10-30 parts soybean meal, 10-30 parts beef bone meal, blood meal, and arginine. The formula contains 10-30 parts powder, 6-22 parts egg yolk powder, 8-30 parts vegetable powder, 6-20 parts meat powder, 0.6-1.2 parts salt, 0.2-0.8 parts sucrose, 0.4-1.2 parts sodium alginate, 0.2-0.8 parts potassium sorbate, 4-12 parts cod liver oil mixture, 0.2-1.2 parts arginine, and 0.2-1.2 parts lysine. The cod liver oil mixture is made by mixing equal parts soybean oil, olive oil, and cod glycerin, but the cod glycerin content and its effect on promoting hair growth are not given.

[0007] The raw materials used in the above patents are animal bone meal, poultry meat, animal offal, traditional Chinese medicine, and vegetable oil, supplemented with cod liver oil, fish oil, or Antarctic krill. This increases the product cost and fails to remove the fishy smell of fish oil. The hair score improvement effect is only 6.04%. How to more effectively improve hair loss, increase hair shine, and improve hair smoothness are problems that need to be solved. Summary of the Invention

[0057]

[0058] Example 2

[0059] Experimental methods:

[0060] This study selected 16 healthy adult cats aged 1-2 weeks with similar weights and randomly divided them into two groups. Each group had 8 replicates, with 1 cat per replicate.

[0061] The control group was fed cat food; the experimental group was fed cat food plus coat-enhancing products; the formal trial period was 20 days, with feeding twice a day, in the morning (10:00) and evening (5:00).

[0062] All experimental cats were housed in the same environment. During the experiment, they had free access to food and water. Temperature and humidity in the cat housing were recorded daily at 8:30 AM and 2:30 PM, and the housing was cleaned regularly. All cats were vaccinated and dewormed during the pre-experiment period. This experimental protocol followed animal welfare guidelines and the animal experimentation procedures of the Northwest A&F University Animal Ethics Committee.

[0063] Test Example 1: Feed Intake Experiment

[0064] The changes in food intake of cats in the control and experimental groups were measured on days 1, 10, and 20 after being fed the pet hair growth nutrient composition. The test results are as follows: Figure 1 As shown, the experimental results indicate that the food intake of the experimental group B was significantly higher than that of the control group A on days 1, 10, and 20 of the experiment. This indicates that feeding cats with the pet hair nutrition composition can improve their willingness and amount of food to eat. Feeding cat food with the pet hair nutrition composition for 20 days can increase the proportion of cats' daily food intake by 43.2%.

[0065] Test Example 2: Weight Test

[0066] The weight changes of cats in the control and experimental groups were measured on days 1, 10, and 20 after being fed the pet hair growth supplement. The test results are as follows: Figure 2 As shown, the weight gain rate of cats in group B was significantly higher than that in group A, increasing the weight gain rate by 2.16%, indicating that feeding pet hair nutrition composition can increase the weight of cats.

[0067] Test Example 3 Hair Score

[0068] The changes in coat scores of cats in the control and experimental groups were measured 20 days after they were fed pet coat nutrition. The coat scoring criteria are shown in Table 2. The test results are as follows: Figure 3 As shown, 6 cats in the experimental group B had a perfect coat score of 3, accounting for 75% of the total, while 3 cats in the control group A had a perfect coat score of 3, accounting for 37.5% of the total. The coat scores of the cats in the experimental group B were significantly higher than those in the control group A, indicating that feeding pet coat nutrition composition can improve the coat condition of cats.

[0071]

[0072] Test Example 4: Number of hairs shed

[0073] The changes in hair loss in cats in the control and experimental groups were measured on days 1, 10, and 20 after being fed pet hair growth supplements. The test results are as follows: Figure 4 As shown, the experimental results indicate that compared to the control group (Group A), the experimental group (Group B) experienced a 36.5% reduction in hair loss, demonstrating that feeding pet hair nutrition composition can significantly improve hair loss in cats.

[0074] Test Example 5: Hair Gloss Score

[0075] The coat luster scores of cats in the control and experimental groups were measured 20 days after being fed pet coat nutrition. The coat luster scores are shown in Table 3. The test results are as follows: Figure 5 As shown, the experimental results indicate that compared with the control group A, the hair luster of the experimental group B increased by 24.1%, and feeding pet hair nutrition composition can significantly improve the hair luster of cats.

[0076] Table 3

[0077]

[0078]

[0079] Test Example 6: Hair Smoothness Score

[0080] The coat smoothness scores of cats in the control and experimental groups were measured on days 1, 10, and 20 after being fed pet coat nutrition. The test results are as follows: Figure 6 As shown, the experimental results indicate that compared with the control group A, the hair luster of the experimental group B increased by 20.7%, and feeding pet hair nutrition composition can significantly improve the smoothness of cats' hair.

[0081]

[0082] In summary, the experimental results show that compared to the group fed cat food, feeding cat food plus a pet coat nutrition combination for 20 days can increase the proportion of cats' daily food intake by 43.2%, increase the proportion of cats' weight gain by 2.16%, improve the condition of cats' coats, reduce the proportion of cats' shedding by 36.5%, increase the proportion of cats' coat smoothness by 20.7%, and increase the proportion of cats' coat shine by 24.1%.

[0083] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
