Description

Technical Field

[0001] The present invention relates to the technical field of pet food additives, and particularly relates to a pet food additive for improving the hair quality of dogs and cats. Background Art

[0002] With the increasing popularity of domestic pets, people are paying more and more attention to the health and appearance of pets. Therefore, the glossiness of pet skin, whether it is delicate and elastic, and whether pet hair is soft, smooth, and shiny have become important criteria for judging the health of pets. However, most commercially available pet foods currently focus on providing the basic nutrients necessary to maintain the life activities of pet dogs and cats. As they age, dogs and cats will experience phenomena such as hair loss, dullness, and discoloration, which seriously affect their health and beauty. Currently, there are mainly two types of foods that can improve the hair quality of pet dogs and cats: one is a health care product with special functions, but such products often have high costs and expensive prices; the other is a pet food directly added with polyunsaturated fatty acids (PUFA), vitamins, minerals, or amino acids. However, in the actual production process, this type of food has problems such as high production costs, imbalance in the proportion of added substances, and large nutritional losses. Long-term feeding may have toxic and side effects on the pet body.

[0003] In addition, directly adding vitamins to pet food easily leads to difficult digestion and absorption by pets, and even excessive poisoning. Moreover, most commercially available pet foods only add ω-6 PUFA, and the improvement effect on pet hair is not good, resulting in more and more voices believing that "adding PUFA is useless". Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention aims to provide a pet food additive for improving the hair quality of dogs and cats.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A pet food additive for improving the hair quality of dogs and cats, including β-carotene, linolenic acid, and linoleic acid; calculated based on every 1 kg of pet food, the addition amount of the β-carotene is 5 - 225 mg / kg; the mass ratio of the linolenic acid in the pet food is 0.09% - 2.1%, and the mass ratio of the linoleic acid in the pet food is 0.5% - 21%.

[0007] Furthermore, the addition of β-carotene is achieved by adding one or more of commercially available β-carotene products, carrots, and pumpkins.

[0008] Furthermore, the addition of linolenic acid is achieved by adding flaxseed. After adding flaxseed to the raw materials of the pet diet, the raw materials of the pet diet together with flaxseed are extruded and puffed to form a semi-finished pet diet, and the toxic components of flaxseed are eliminated through extrusion and puffing.

[0009] Furthermore, the conditions for extrusion and puffing are as follows: the moisture content of the raw materials of the pet diet is 26%; the extrusion temperature is controlled in three stages at 80°C, 100°C, and 140°C; the screw speed is 150 - 250 r / min, and the feeding speed is 180 - 300 g / min.

[0010] Even further, the addition of linoleic acid is achieved by adding one or more of soybean oil, peanut oil, and sunflower oil.

[0011] Even further, after extruding and puffing the raw materials of the pet diet to obtain a semi-finished pet diet, one or more of soybean oil, peanut oil, and sunflower oil are sprayed onto the semi-finished pet diet.

[0012] Even further, when adding carrots and / or pumpkins to achieve the addition of β-carotene, the carrots and / or pumpkins are added to the raw materials of the pet diet and then extruded and puffed together; when adding commercially available β-carotene to achieve the addition of β-carotene, after extruding and puffing the raw materials of the pet diet to obtain a semi-finished pet diet, the commercially available β-carotene product is dissolved in linoleic acid and then sprayed onto the semi-finished pet diet to form a finished diet.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. Fat-soluble vitamin A has a positive effect on the hair of pets and can maintain the gloss of the hair. However, direct addition is likely to cause overdose and poisoning. The present invention selects β-carotene with strong provitamin A activity as the source of vitamin A. Because when the body lacks vitamin A, the bioconversion rate of β-carotene increases, but when there is a large amount of β-carotene in the body, the process of bioconversion to vitamin A will be inhibited, which can avoid poisoning caused by excessive vitamin A in the body.

[0015] 2. PUFA can maintain the health of the hair of dogs and cats by promoting hair growth, enhancing the anti-inflammatory ability of the skin, and strengthening the skin barrier function. The present invention provides ω-3 PUFA by adding linolenic acid and provides ω-6 PUFA by adding linoleic acid. The combined addition of ω-3 PUFA and ω-6 PUFA can achieve an ideal effect of improving hair. On this basis, the present invention controls the ratio of ω-3 PUFA and ω-6 by controlling the ratio of linolenic acid and linoleic acid, and through the combination of extrusion and puffing technology and spraying method, it can reduce toxicity while being more conducive to pet digestion and absorption, making the effect of improving the hair quality of dogs and cats better.

[0016] 3. The flaxseed added in the present invention contains a large amount of unsaturated fatty acids (α-linolenic acid), which has antioxidant functions, nourishes the skin to make the coat shiny, and can also improve intestinal function, increase absorption ability and intestinal peristalsis ability, and maintain the normal structure of the intestinal flora. Detailed implementation manners

[0017] The present invention will be further described below. It should be noted that this embodiment is based on the present technical solution, and detailed implementation manners and specific operation processes are given, but the protection scope of the present invention is not limited to this embodiment.

[0018] Example 1

[0019] Poodle dogs of about 1 year old with similar body weights and good health conditions were selected and divided into 3 groups, namely a control group (basic diet), an experimental group I (basic diet, in which 0.9% soybean oil (i.e., 0.5% linoleic acid) and 0.3% flaxseed (i.e., 0.09% linolenic acid) were added by mass percentage), and an experimental group II (a well-known brand of hair-improving dog food). The effects of linoleic acid and linolenic acid on the coat quality of poodle dogs were explored by measuring the hair scale density, softness and brightness of each group of dogs. The results showed that compared with the control group, the hair scale density and softness of the experimental group I increased significantly, and the hair brightness of the experimental group II increased significantly. In addition, the apparent digestibility of dry matter, calcium and phosphorus in the basic diet of the experimental group I increased significantly. Therefore, the combined addition of linoleic acid and linolenic acid can improve the intestinal health and hair quality of pet dogs, and the effect even reaches the level of the best-selling commercial hair-improving dog food on the market.

[0020] Example 2

[0021] One-year-old Chinese rural cats with similar body weights were selected and divided into 6 groups, namely the control group (basic diet), experimental group I (basic diet, added with 0.9% soybean oil (i.e., 0.5% linoleic acid), 0.3% flaxseed (i.e., 0.09% linolenic acid), and 5 mg / kg commercially available β-carotene) by mass percentage), experimental group II (basic diet, added with 0.9% soybean oil (i.e., 0.5% linoleic acid), 0.3% flaxseed (i.e., 0.09% linolenic acid), and 25 mg / kg commercially available β-carotene) by mass percentage), experimental group III (basic diet, added with 0.9% soybean oil (i.e., added with 0.5% linoleic acid), 0.3% flaxseed (i.e., added with 0.09% linolenic acid), and 125 mg / kg commercially available β-carotene) by mass percentage), experimental group IV (basic diet, added with 0.9% soybean oil (i.e., added with 0.5% linoleic acid), 0.3% flaxseed (i.e., added with 0.09% linolenic acid), and 225 mg / kg commercially available β-carotene) by mass percentage), experimental group V (basic diet, added with 0.9% soybean oil (i.e., added with 0.5% linoleic acid), 0.3% flaxseed (i.e., added with 0.09% linolenic acid), and 325 mg / kg commercially available β-carotene) by mass percentage). The effects of carotene and unsaturated fatty acids on the hair quality of cats were explored through indicators such as hair softness, brightness, and follicle depth. The results showed that on the basis of adding unsaturated fatty acids, the hair softness of the 5 mg, 25 mg, 125 mg, and 225 mg groups was significantly higher than that of the 325 mg group, but all were higher than that of the control group; the hair brightness of the 25 mg and 125 mg groups was significantly higher than that of the control group; the primary follicle depth of the 5, 25, 125, and 225 mg groups was significantly higher than that of the control group and also higher than that of the 325 mg group. Therefore, 5 - 225 mg / kg of β-carotene can improve the hair quality of cats and extend the growth period of hair follicles.

[0022] Example 3

[0023] This example provides a method for preparing the pet diets used in experimental groups I - V described in Example 2. First, flaxseed is added to the raw materials of the basic diet, and then the raw materials of the basic diet together with flaxseed are subjected to extrusion expansion. The conditions for the extrusion expansion are as follows: the moisture content of the raw materials of the basic diet is 26%; the extrusion temperature is controlled in three stages at 80°C, 100°C, and 140°C; the screw speed is 150 r / min, and the feeding speed is 180 g / min. After the extrusion expansion is completed, a semi-finished pet diet is formed. Commercially available β-carotene is dissolved in soybean oil and then sprayed onto the semi-finished pet diet to form a finished diet.
