Abstract
Description
Technical Field
[0001] The invention relates to the field of pet food, and in particular to a pet food with hair beautifying function and a preparation method and application thereof. Background Art
[0002] At present, the rapid increase in the number of cat owners has formed a huge industrial chain in the cat economy. With the refinement of cat diets, people's requirements for the quality of cat feeding have also increased. The glossiness and health of pet hair are an aspect that pet owners pay more attention to. Pet owners pay more and more attention to the appearance and health of their pets, and the demand for pet products and services is also growing.
[0003] Pet food such as cat strips are popular in the pet market due to their convenient use and rich nutritional ingredients. Cat strips are usually in the form of ointment or paste, with a variety of flavors, and are easy to feed. They can not only be used directly as snacks, but can also be mixed with daily cat food to facilitate cats' nutritional intake. Cat strips also have a variety of flavors to cater to the taste preferences of different cats, increasing their appetite and eating pleasure. Not only that, cat strips are easy to carry and store due to their unique small packaging design, and are suitable for use at home or on the go, allowing pet owners to more conveniently manage their cats' nutritional intake.
[0004] Patent document CN112690371A discloses a soft strip feed for ragdoll cats, which includes the following ingredients: fish oil, multivitamins, Bacillus subtilis, lactic acid bacteria, fish meal, taurine, peas, meat meal, multiminerals, fruits, calcium dihydrogen phosphate and yeast powder.
[0005] Patent document CN116616381 A discloses a staple cat strip containing water beetles and American cockroach extract residues. The staple cat strip raw materials contain complex vitamins, trace elements, water beetles, American cockroach extract residues, minced meat, water, taurine, a thickener and catnip. The complex vitamins and trace elements are selected from any one of vitamin A, B vitamins, vitamin C, vitamin D, vitamin E, folic acid, niacinamide, calcium pantothenate, calcium, magnesium, phosphorus, copper, iron, manganese, and zinc, or a combination thereof.
[0006] It can be seen that the pet foods disclosed in the prior art, especially cat strips, mostly use fish oil or vitamin E to promote cat hair growth and maintain glossiness, but these ingredients cannot fundamentally solve the problem of cat hair health. At present, there is an urgent need for a pet food formula based on natural animal and plant raw materials and with Chinese herbal ingredients as additives, which can fundamentally solve the problem of cat hair health by regulating the metabolic balance of the cat's body.

[0103] Experimental Results
[0104] Hair evaluation results after feeding pet cats for 28 days
[0105] 1. Evaluation indicators
[0106] (1) The brightness of the coat is based on natural light as the light source, and is divided into five levels: dull, darker, normal, brighter, and brighter, with a score of 1 to 5 points; (2) The smoothness is based on the consistency of the coat's appearance and direction and the feel, and is divided into five levels: knotted, slightly knotted, rough and split, normal, and smooth, with a score of 1 to 5 points; (3) The skin condition is divided into five levels: extremely dry and dandruff, dry and dandruff, normal, extremely moist and shiny, and moist and shiny. (4) Skin elasticity is divided into five levels: no rebound, slow rebound, normal, fast rebound, and immediate rebound, with a score of 1 to 5 points; (5) The strength of the feel is based on the strength of the hair on the palm when touching the hair, which is divided into five levels: very weak, weak, normal, strong, and very strong, with a score of 1 to 5 points; (6) The hip blowing method is used for scoring, with a total of 5 levels: dense hair, plump feel, no skin gaps are seen, and 5 points are above dense. Plump hair, skin gaps are 1mm 2 The coat is dense and scored 4 points. The coat is normal and scored 3 points. The coat is slightly sparse, with skin gaps of 1 to 2 mm. 2 The following is dense, medium, 2 points. The coat is sparse, and the skin gap is 2mm. 2 The above is a score of 1. Finally, the data of each group were statistically analyzed using GraphPad Prism 8.0.
[0107] 1. Evaluation Results
[0108] (1) If Figure 1As shown, in terms of coat brightness, the cat strip formula of Example 1 has the highest score in improving the coat brightness of pet cats, and is significantly higher than all other groups, indicating that the cat strip formula of Example 1 has the best effect in improving the coat brightness. The scores of Example 2, Example 3, Example 4, and Example 5 are close, all around 4 points, slightly lower than that of Example 1. The scores of Comparative Example 1, Comparative Example 2, and Comparative Example 3 are relatively low, about 3 points, indicating that they are significantly lower than Example 1 and other examples in terms of coat brightness. It can be seen that, compared with feeding cat strips without yam and scallops, or containing only one component of yam or scallops, feeding cat strips containing both yam and scallops can better promote the coat brightness of pets, and yam and scallops can cooperate with each other in promoting coat brightness.
[0109] (2) If Figure 2 As shown, in terms of fur color smoothness, Example 1 has the highest score, close to 5 points, indicating that the cat strip formula of Example 1 performs best in terms of fur smoothness, and there is a significant difference between it and the comparative example. The scores of Example 2, Example 3, Example 4, and Example 5 are all close to 4.5 points, but slightly lower than that of Example 1, and still significantly higher than the comparative example. The scores of Comparative Example 1, Comparative Example 2, and Comparative Example 3 are around 3.5 points, which are significantly lower than all the examples in terms of fur smoothness. It can be seen that, compared with feeding cat strips without yam and scallops, or containing only one component of yam or scallops, feeding cat strips containing both yam and scallops can better improve the fur color softness of pets, and yam and scallops have a significant synergistic effect in improving hair softness.
[0110] (3) If Figure 3 As shown, in terms of skin condition, Example 1 has the highest score, close to 5 points, indicating that the cat strip formula of Example 1 has the best effect in improving skin condition. The scores of Example 2 and Example 5 are about 4.5 points, and the effect of improving skin condition is significantly better than that of Comparative Example 1 and Comparative Example 3. The score of Example 3 is about 4 points, which is significantly better than Comparative Example 1. The score of Example 4 is also about 4.5 points, which is significantly better than Comparative Example 1 and Comparative Example 3. Comparative Example 1 has the lowest score, about 3 points, indicating that its effect in improving skin condition is significantly lower than all the examples. The score of Comparative Example 2 is about 3.5 points, and its effect in improving skin condition is significantly lower than that of Example 1, Example 2, Example 5 and Example 4. The score of Comparative Example 3 is about 3.5 points, indicating that its effect in improving skin condition is significantly lower than that of Example 1, Example 2, Example 5 and Example 4. It can be seen that compared with feeding cat strips without yam and scallop, or containing only one component of yam or scallop, feeding cat strips containing both yam and scallop can improve the softness of pets' fur color. Yam and scallop have a significant synergistic effect in improving the softness of hair.
[0111] (4) If Figure 4 As shown, in terms of skin elasticity, Example 1 has the highest score, close to 5 points, indicating that the cat strip formula of Example 1 has the best effect in improving skin elasticity. The scores of Example 2 and Example 5 are about 4.5 points, indicating that the effects of these two examples in improving skin elasticity are significantly better than those of Comparative Examples 1, 2 and 3. The score of Example 3 is about 4 points, and its effect in improving skin elasticity is significantly better than that of Comparative Examples 1 and 2. The score of Example 4 is about 4 points, which is significantly better than that of Comparative Examples 1 and 2. Comparative Example 1 has the lowest score, about 3 points, indicating that its effect in improving skin elasticity is significantly lower than that of all examples. The scores of Comparative Examples 2 and 3 are about 3.5 points, indicating that their effects in skin elasticity are significantly lower than that of all examples. It can be seen that, relative to feeding cat strips that do not contain yam and scallops, or contain only one component of yam or scallops, feeding cat strips containing both yam and scallops can improve the skin elasticity of pets, and yam and scallops have a significant synergistic effect in improving the skin elasticity of pets.
[0112] (5) Figure 5 As shown, in terms of hand feel strength, Example 1 has the highest score, close to 5 points, indicating that the cat strip formula of Example 1 has the best effect in improving hand feel strength. The scores of Example 2 and Example 4 are about 4.5 points, indicating that the effects of these two embodiments in terms of hand feel strength are significantly better than those of Comparative Examples 1, 2 and 3. The scores of Example 3 and Example 5 are about 4.3 points, indicating that their effects are significantly better than those of Comparative Examples 1 and 2. Comparative Example 1 has the lowest score, about 3 points, indicating that its effect in improving hand feel strength is significantly lower than all embodiments. The scores of Comparative Examples 2 and 3 are slightly higher than Comparative Example 1, at about 3.5 points, indicating that their effects in terms of hand feel strength are significantly lower than all embodiments. It can be seen that, relative to feeding cat strips that do not contain yam and scallops, or contain only one component of yam or scallops, feeding cat strips containing both yam and scallops can improve the hand feel strength, and yam and scallops have a significant synergistic effect in improving hand feel strength.
[0113] (6) If Figure 6As shown, in terms of coat density, the scores of Example 1, Example 2, Example 3, Example 4, and Example 5 are all above 4 points, indicating that these examples have similar effects in improving coat density, and the effects are significantly better than Comparative Example 1, Comparative Example 2, and Comparative Example 3. Comparative Example 1 has the lowest score, indicating that its effect in coat density is not as good as that of each example. The scores of Comparative Example 2 and Comparative Example 3 are slightly better than Comparative Example 1 but not as good as that of Example 1, indicating that their effects in coat density are significantly lower than those of all examples. It can be seen that, compared with cat strips that do not contain yam and scallops, or contain only one component of yam or scallops, cat strips that are fed with both yam and scallops can better improve coat density, and yam and scallops have a significant synergistic effect in improving coat density.
[0114] Scanning electron microscopic evaluation results of pet cat hair after feeding cat strips for 28 days
[0115] 1. Evaluation Method
[0116] At 28 days, hair samples were collected from the left buttocks of each cat. During sampling, the hair in the required area was gently shaved to reduce discomfort to the animal. The hair samples were fixed on a sample tray suitable for SEM observation. The hair diameter, hair scale length and hair scale height of each sample were accurately measured using a Zeiss Sigma300 / Oxford Spectroscopy SEM. High-resolution hair surface images were recorded for subsequent analysis. The changes in hair diameter, hair scale length and hair scale thickness of cats in the control group and each experimental group were compared and analyzed. Statistical software was used to process the data and evaluate the effects of feeding different formulas on hair microstructure. ImageJ was used to process the photographic results, and graphpad prism 8.0 was used for data analysis.
[0117] 2. Evaluation Results
[0118] The scanning electron microscope images of the cat strips prepared in each embodiment and comparative example after 28 days of pet cat hair are as follows: Figure 7-14 As shown (Mag = 1.0KX; scale bar = 10 μm).
[0119] (1) The thickness, density, shape and arrangement structure of the scales can directly affect the gloss, softness and feel of the hair. In terms of the height of the hair scales, the greater the height of the hair scales, the fewer scales per unit length will be, the smaller the density of the scales will be, and the smoother the hair will be. Fig.15As shown, Example 1 has the highest hair scale height, which is close to 0.8 µm, indicating that Example 1 is significantly higher than the comparative example in terms of hair scale height. Example 2, Example 3, Example 4, and Example 5 have hair scale heights of approximately 0.6 µm to 0.7 µm, and these examples are significantly higher than the comparative example in terms of hair scale height. Comparative Example 1 has the lowest hair scale height, which is approximately 0.4 µm, indicating that its hair scale height is significantly lower than all the examples. Comparative Examples 2 and 3 have hair scale heights of approximately 0.5 µm, which are significantly lower than all the examples in terms of hair scale height. It can be seen that, compared with cat strips that do not contain yam and scallops, or contain only one component of yam or scallops, cat strips that are fed with both yam and scallops can better increase the height of hair scales, and yam and scallops have a significant synergistic effect in increasing the height of hair scales.
[0120] (2) If Fig.16 As shown, in terms of hair scale length, the smaller the length of the scale, the smaller the friction coefficient of the hair and the smoother the hair surface. The hair scale lengths of Examples 1 to 5 are all around 6 µm, indicating that these examples are significantly better than the comparative examples in reducing the length of the hair scale. The hair scale length of Comparative Example 1 is the highest, close to 12 µm, indicating that Comparative Example 1 has the worst effect in terms of hair scale length, which is significantly different from all the examples. The hair scale length of Comparative Example 2 is about 10 µm, which is significantly higher than all the examples. The hair scale length of Comparative Example 3 is close to 12 µm, which is significantly higher than all the examples. It can be seen that, compared with cat strips that do not contain yam and scallops, or contain only one component of yam or scallops, cat strips that are fed with both yam and scallops can reduce the length of the hair scales, and yam and scallops have a significant synergistic effect in reducing the length of the hair scales.
[0121] (3) If Fig.17 As shown, there is no significant difference in hair diameter between the embodiment and the control groups. This may be because the hair diameter is affected by multiple factors such as cat breed, cat age and cat gender. The effect of late intervention is not obvious, and a longer-term feeding test or more in-depth tests on cats of similar breed and age are needed.
[0122] Evaluation of the percentage of weight gain, percentage of hair loss reduction and fur color saturation of pet cats after feeding cat strips for 28 days
[0123] 1. Evaluation Method
[0124] 1. Evaluation method for pet cats' weight gain percentage and hair loss reduction percentage: Use an electronic scale to record weight changes every week. Use the same pet comb to comb 30 cm from the neck along the spine three times in a row, collect the hair each time and weigh the collected hair with an electronic balance.
[0125] 2. Evaluation method of pet cat fur color saturation:
[0126] The test was conducted at normal room temperature (15-23°C) and in a room with normal light intensity of 100-300 lux. A colorimeter was used for the measurement, and the device was blank-calibrated before the measurement. The observation angle was 10°, the light source was D65, and the measurement aperture was 10mm. The animal to be tested was in a normal anatomical posture (standing), and lying behavior was not allowed. The color difference analysis was performed on the left hind leg of the animal.
[0127] 2. Evaluation Results
[0128] (1) If Fig.18 As shown, in terms of the percentage of weight gain, the percentage of weight gain in Example 1 is the highest, close to 30%, indicating that Example 1 has the best effect in promoting weight gain, and there is a significant difference between the comparative examples. The percentages of weight gain in Example 2, Example 3, Example 4, and Example 5 are between 20% and 25%, respectively, indicating that the effects of these embodiments in promoting weight gain are significantly better than all comparative examples. The percentage of weight gain in Comparative Example 1 is the lowest, about 10%, indicating that its effect in promoting weight gain is significantly lower than all examples. The percentages of weight gain in Comparative Examples 2 and 3 are about 15%, respectively, indicating that their effects in promoting weight gain are significantly lower than all examples. It can be seen that, relative to feeding cat strips that do not contain yam and scallops, or contain only one component of yam or scallops, feeding cat strips containing both yam and scallops can promote weight gain, and yam and scallops have a significant synergistic effect in promoting weight gain.
[0129] (2) If Fig.19 As shown, in terms of the percentage reduction of hair loss, Example 1 has the highest percentage reduction of hair loss, which is close to 90%, indicating that Example 1 has the best effect in reducing hair loss, and there is a significant difference between all comparative examples. The percentage reduction of hair loss in Example 2, Example 4, and Example 5 is about 80%, 75%, and 85%, respectively, indicating that the effects of these embodiments in reducing hair loss are significantly better than all comparative examples. The percentage reduction of hair loss in Example 3 is about 70%, which is significantly better than the comparative examples. The percentage reduction of hair loss in Comparative Example 1 is the lowest, which is about 40%, indicating that its effect in reducing hair loss is significantly lower than all the examples. The percentage reduction of hair loss in Comparative Example 2 and Comparative Example 3 is about 50% and 60%, respectively, indicating that their effects in reducing hair loss are significantly lower than all the examples. It can be seen that compared with cat strips containing no yam and scallops, or containing only one component of yam or scallops, cat strips fed with both yam and scallops can reduce hair loss. Yams and scallops have a significant synergistic effect in reducing hair loss.
[0130] (3) If Fig. 20 As shown, the fur color saturation of Example 1 is the highest, close to 25, indicating that Example 1 has the best effect in improving the fur color saturation, and there is a significant difference between it and the comparative example. The fur color saturation of Example 2 and Example 4 is between 20 and 23, respectively, indicating that the effects of these two embodiments in improving the fur color saturation are significantly better than the comparative example. The fur color saturation of Example 3 and Example 5 is about 21, and its effect is significantly better than the comparative example. The fur color saturation of Comparative Example 1 is the lowest, about 12, indicating that its effect in improving the fur color saturation is significantly lower than all the examples. The fur color saturation of Comparative Example 2 and Comparative Example 3 is between 14 and 15, respectively, indicating that their effects in improving the fur color saturation are significantly lower than all the examples. It can be seen that, compared with cat strips fed without yam and scallops, or containing only one component of yam or scallops, feeding cat strips containing both yam and scallops can improve the fur color saturation, and yam and scallops have a significant synergistic effect in improving the fur color saturation.
