Description

Technical Field

[0001] The invention relates to the technical field of pet food, in particular to pet food for dogs and cats and a preparation method thereof. Background Art

[0002] As modern society pays more and more attention to the health and welfare of pets, the nutritional needs and health management of dogs and cats as companion animals have become an important research direction in the pet food industry. Traditional dog and cat feeds mainly focus on providing basic nutrients such as protein, fat, carbohydrates, vitamins and minerals to meet their daily physiological needs. However, with the deepening of research on dog and cat health, people have gradually realized that providing only basic nutrients is not enough to meet their comprehensive health needs.

[0003] The nutritional needs of dogs and cats vary significantly at different life stages, health conditions, and living environments. For example, young dogs and cats need more protein and energy to support growth and development, while older dogs and cats need more antioxidants and joint protection ingredients. In addition, dogs and cats need special nutritional support for their immune systems and overall health when facing environmental stress, illness, or surgery.

[0004] There are many types of dog and cat feed products on the market, but most products are still at the stage of providing basic nutrients. Although some high-end products have begun to add functional ingredients such as probiotics, Omega-3 fatty acids and antioxidants, the types and proportions of these ingredients are often relatively single, making it difficult to fully meet the needs of dogs and cats in different health conditions.

[0005] In addition, although some feed products claim to contain herbal ingredients, the selection and use of these ingredients often lack scientific basis and systematization. Many products only add a small amount of herbal plants as a gimmick, and the actual effect is limited. At the same time, the amount of herbal plants added and the method of use are also lacking in standardization, resulting in unstable product effects.

[0006] Chinese veterinary theory emphasizes "preventive treatment" and "holistic conditioning", and believes that the health of animals is the result of a balance between the internal and external environment. According to classic Chinese veterinary literature such as "Shennong's Herbal Classic", "Huoshou Cizhou", and "Compendium of Materia Medica", many herbs have multiple functions such as conditioning the body, enhancing immunity, and improving digestion. These herbs not only have medicinal value, but also have food properties, which conforms to the concept of "medicine and food have the same origin".

[0007] For example, herbs such as Codonopsis pilosula, Astragalus membranaceus, and Atractylodes macrocephala are widely used in traditional Chinese veterinary medicine to enhance immunity and improve digestive function; Lycium barbarum, Hawthorn, and Coix seeds have antioxidant, anti-inflammatory, and metabolic regulating effects. The rational use of these herbs in dog and cat feed can effectively improve their health level.

[0008] There is an urgent need in this field to develop a natural plant extract feed that is based on the holistic view of traditional Chinese veterinary medicine and modern nutritional metabolism theory and achieves multi-target conditioning through scientific compatibility. Therefore, a pet food for dogs and cats and a preparation method thereof are proposed to break through the single functional limitation of traditional herbal additives while meeting the requirements of palatability, nutritional balance and functional stability.

[0416] IgA level: The IgA level in the experimental group was also significantly higher than that in the control group (P<0.01).

[0417] White blood cell count: The white blood cell count in the experimental group was higher than that in the control group (P<0.05).

[0418] Therefore, the food for dogs and cats of the present invention shows a significant effect in enhancing immune function, can improve IgG and IgA levels, and increase white blood cell counts, which is helpful to enhance the immunity of pets.

[0430] Data collection: The skin and hair conditions of the test animals were recorded weekly during the experiment, including hair gloss, skin elasticity and hair loss, and scored using a professional scoring system (out of 10 points, the higher the score, the better the skin and hair condition).

[0431] (2) Test results

[0432]

[0433] Skin health score: The skin health score of the experimental group was significantly higher than that of the control group (P<0.01).

[0434] Hair gloss score: The hair gloss score of the experimental group was also significantly higher than that of the control group (P<0.01).

[0435] Hair removal rate: The hair removal rate of the experimental group was significantly lower than that of the control group (P<0.01).

[0436] Therefore, the food for dogs and cats of the present invention shows a significant effect in improving skin and hair, can improve the skin health score and hair glossiness score, and reduce the hair loss rate, which helps to maintain the skin and hair health of pets.
