If the specific conditions are not specified in the embodiments, they are carried out according to conventional conditions or conditions recommended by the manufacturer. If the manufacturer of the reagents or instruments used is not specified, they are all conventional products that can be purchased commercially.

[0054] The following is a detailed description of a Chinese herbal feed additive for sea bass and its processing equipment and application according to an embodiment of the present invention.

[0055] The embodiment of the present invention provides a Chinese herbal medicine feed additive for sea bass, which is made of a variety of raw materials, and the various raw materials include, by weight: 20-30 parts of gallnut, 20-30 parts of sophora flavescens, 20-30 parts of houttuynia cordata, 10-20 parts of orange, and 10-20 parts of lemon. Preferably, in a preferred embodiment of the present invention, the various raw materials include, by weight: 24-26 parts of gallnut, 24-26 parts of sophora flavescens, 24-26 parts of houttuynia cordata, 13-18 parts of orange, and 12-17 parts of lemon.

[0056] Further specifically and preferably, in a preferred embodiment of the present invention, the plurality of raw materials include, by weight: 25 parts of gallnut, 25 parts of sophora flavescens, 25 parts of houttuynia cordata, 15 parts of orange and 15 parts of lemon.

[0057] It should be noted that the Chinese herbal feed additive for seabass provided in the embodiment of the present invention configures gallnut, sophora flavescens, houttuynia cordata, orange and lemon in a reasonable proportion, and the obtained feed additive is used in the cultivation of seabass, which is a specific and significant improvement. It can be said that it provides a green and effective feed additive for aquaculture and improves the nutritional quality of seabass. Specifically, the seabass cultivated with the Chinese herbal feed additive for seabass of the present application has significant changes in muscle nutritional components, increased ash and crude protein, and reduced moisture and crude fat; the essential amino acids and total amino acids are increased, and the AAS, CS and EAAI scores are improved; the fatty acid composition is optimized, the proportion of saturated fatty acids is reduced, and the proportion of unsaturated fatty acids is increased. It should be emphasized that the increase in ash content brings richer inorganic components such as minerals, and the increase in crude protein consolidates the status of high-quality protein source, which is beneficial to growth and muscle development, while the reduction in water and crude fat optimizes the meat quality and fat structure, reduces the risk of fat intake, and improves taste and flavor; in addition, in terms of amino acid composition, the AAS and CS scores of isoleucine, valine, leucine and lysine are increased, and the EAAI score is also significantly improved, indicating that the nutritional value of protein is improved; in addition, in terms of fatty acid composition, the addition of Chinese herbal feed additives reduces the proportion of saturated fatty acids and increases the proportion of unsaturated fatty acids, especially the content of monounsaturated fatty acids and polyunsaturated fatty acids, the mass fraction of DHA and EPA, and the ΣPUFAn3 / ΣPUFAn6 ratio are greatly improved, which optimizes the fatty acid composition ratio and improves the nutritional value of lipids.

[0058] It should be further explained that the Chinese herbal medicine feed additive for sea bass provided in the present application has the above-mentioned effects. The applicant believes that there are at least the following reasons and mechanisms:

[0059] First of all, from the perspective of the efficacy of a single component:

[0060] Gallnut promotes digestion and absorption: the tannic acid and other ingredients contained in gallnut can combine with the protein in the feed to form a complex that is easier for fish to digest, preventing the protein from passing quickly through the intestine without being fully absorbed, thereby improving the utilization rate of feed protein; maintaining intestinal health: its astringent properties help repair damaged intestinal mucosa, maintain the integrity of intestinal epithelial cells, optimize the structure of intestinal microbial flora, inhibit the growth of harmful bacteria, create a suitable living environment for beneficial bacteria such as bifidobacteria, and enhance intestinal digestion and absorption functions.

[0061] Sophora flavescens, regulates metabolic function: alkaloids such as matrine can regulate the endocrine system of fish, affect the secretion of hormones related to carbohydrate, fat and protein metabolism in fish, and promote the rational distribution and efficient utilization of nutrients, such as stimulating insulin secretion to regulate blood sugar, guiding fat to be deposited or decomposed for energy in a more orderly manner, reducing the metabolic burden caused by excessive fat accumulation, and improving the quality of fish meat; increase appetite: Sophora flavescens's unique smell stimulates the olfactory receptors of fish to a certain extent, stimulates appetite, increases the fish's active food intake, and ensures sufficient intake of various nutrients. Its ingredients indirectly participate in the synthesis and activation process of digestive enzymes, accelerate the digestion rate of food in the gastrointestinal tract, and continuously provide energy for the growth of fish.

[0062] Houttuynia cordata provides vitamins and minerals: Houttuynia cordata is rich in vitamin C, B vitamins, and various minerals such as potassium, calcium, and magnesium, which can supplement the trace nutrients that are easily lacking in fish feed. Vitamin C enhances the fish's immunity and participates in collagen synthesis, maintaining the health of the fish's connective tissue. Mineral elements ensure the fish's osmotic pressure balance, nerve conduction, and normal bone development, promoting growth and development in all aspects; optimize the nutritional structure of feed: as a natural feed additive, it enriches the nutritional level of feed, makes up for the nutritional limitations of conventional feed, and works together with basic feed to improve the overall nutritional balance, allowing fish to obtain energy while fully absorbing essential amino acids, fatty acids and various trace elements, avoiding nutritional deficiencies that limit growth potential.

[0063] Oranges, vitamin supplement: Orange pulp and peel are rich in vitamin A, vitamin C and some B vitamins, which are indispensable for fish to maintain normal physiological functions. For example, vitamin A is beneficial to the development of fish retina and differentiation of immune cells, vitamin C is antioxidant, promotes iron absorption, strengthens the fish's ability to resist stress and infection, supports the healthy growth of fish from multiple dimensions, improves growth performance and disease resistance, and indirectly enhances the nutritional value of fish; provides energy and dietary fiber: The natural sugars contained in oranges can replenish energy for fish, and can provide emergency energy when the feed energy is insufficient or the fish consumes a lot of energy due to stress; in addition, although the dietary fiber in the peel cannot be completely digested by fish, it can promote intestinal peristalsis, carry out the excretion of toxins in the intestine, maintain stable digestive function, ensure smooth nutrient absorption channels, and facilitate long-term and efficient nutrient intake.

[0064] Lemon is rich in nutrients: In addition to vitamin C, lemon also contains mineral ions such as calcium, phosphorus, iron, and antioxidants such as flavonoids. Vitamin C and flavonoids work together to remove free radicals in fish, reduce oxidative damage, and maintain cell activity. Mineral ions participate in bone mineralization, blood circulation, and a variety of enzymatic reactions, maintaining the efficient operation of the basic physiological metabolism of fish and ensuring the normal transportation and transformation of nutrients in the body; improve feed palatability and preservation: The unique sour taste of lemon juice improves the smell of feed, stimulates the taste of fish, and increases feed intake rate. Its acidic properties inhibit the growth of mold and bacteria in feed, delay feed oxidation and rancidity, and maintain the stability of feed nutrients. This ensures that fish continue to obtain high-quality, non-deteriorated nutrient sources during feeding, avoiding nutrient loss and damage to fish health due to feed deterioration.

[0065] Secondly, focusing on the mixed synergistic effect of the five components, there are four important synergistic mechanisms, specifically:

[0066] 1. Nutrient complementation and strengthening

[0067] Amino acid balance: Gallnut, Sophora flavescens, etc. contain a certain amount of amino acids, which complement the protein sources in the feed, making the amino acids ingested by fish more complete and in a more reasonable proportion, close to their ideal protein model, thereby improving the biological value of protein and being more conducive to fish growth and muscle protein deposition.

[0068] Synergy of vitamins and minerals: Houttuynia cordata is rich in vitamin C and various minerals. Oranges and lemons are also rich in vitamins and minerals. They work together with the trace elements in gallnut and Sophora flavescens to meet the fish's needs for various vitamins and minerals, and play a synergistic role in the fish's physiological metabolism, such as participating in bone development, hematopoietic function, immune regulation, etc.

[0069] (II) Promoting and optimizing digestion and absorption

[0070] Regulation of digestive enzyme activity: Certain ingredients in Sophora flavescens can stimulate the digestive glands of fish to secrete more digestive enzymes, such as protease, amylase and lipase, and increase the digestion speed and degree of feed in the gastrointestinal tract. Gallnut can improve the intestinal environment and make the digestive enzymes more active in a suitable pH and ion environment, thereby promoting the digestion of nutrients.

[0071] Intestinal barrier function maintenance: Gallnut has an astringent effect, which can repair and protect the intestinal mucosa of fish, reduce the occurrence of intestinal inflammation, and maintain the integrity of the intestinal mucosa. The active ingredients in Houttuynia cordata, oranges, and lemons have certain antibacterial and anti-inflammatory effects, which can inhibit the growth of harmful intestinal bacteria, promote the reproduction of beneficial bacteria, optimize the intestinal microecological environment, and jointly improve the intestinal absorption capacity of nutrients.

[0072] (III) Immune regulation and anti-stress

[0073] Immune enhancement: Gallnut, Sophora flavescens, and Houttuynia cordata all contain a variety of active ingredients with immunomodulatory effects, such as tannins in gallnut, matrine in Sophora flavescens, and flavonoids in Houttuynia cordata. They can stimulate the immune system of fish, enhance the activity and phagocytic ability of immune cells, and improve the nonspecific and specific immune functions of fish.

[0074] Improved anti-stress ability: Antioxidants such as vitamin C and flavonoids in oranges and lemons, as well as some active ingredients in gallnut, sophora flavescens, and houttuynia cordata, can remove free radicals in fish and reduce the damage caused by oxidative stress to the fish. At the same time, these ingredients can also regulate the level of stress hormones in fish, so that fish can better maintain physiological balance when facing stress factors such as environmental changes and breeding operations, and reduce the consumption of nutrients and metabolic disorders caused by stress reactions.

[0075] (IV) Growth performance promotion and meat quality improvement

[0076] Growth hormone regulation: Alkaloids and other ingredients in Sophora flavescens may affect the secretion and release of growth hormones by regulating the endocrine system of fish, thereby promoting the growth of fish. At the same time, the comprehensive supplementation of nutrients and the optimization of digestion and absorption also provide sufficient material basis and energy support for the growth of fish, accelerating the growth rate of fish and improving feed conversion rate.

[0077] Improved meat quality: Through synergistic effects, fish can absorb various nutrients in a more balanced manner, the protein content and quality in the muscles are improved, and fat deposition is more reasonable; in addition, the intake of antioxidants and the enhancement of immune function reduce fat oxidation and muscle damage, thereby improving the quality of fish meat, making it taste more delicious and have higher nutritional value.

[0078] In addition, an embodiment of the present invention further provides an application of a Chinese herbal feed additive for sea bass, which applies the above-mentioned Chinese herbal feed additive for sea bass to fish farming.

[0132] Test example

[0133] In order to verify the technical effect of the Chinese herbal medicine feed additive for sea bass provided by this application, the applicant conducted a sea bass breeding experiment, specifically:

[0134] 1. Test materials

[0135] 200 healthy, normal-colored, and similar-aged sea bass seedlings were selected and purchased from Guiyang Longli Yumi Agricultural Development Company. They were randomly divided into two groups, an experimental group and a control group, wherein the experimental group was fed with the herbal feed additive of the present application (the added amount was 0.1% of the feed weight), and the control group was fed with ordinary feed with antibiotics added (the added amount was 0.1% of the feed weight).

[0136] 2. Feeding and management

[0137] The traditional breeding method feeds regular perch feed, and the Chinese herbal medicine breeding method feeds the perch with added Chinese herbal medicine feed. The bottom sediment is cleaned weekly and the water is changed by 10%-20%. It should be noted that the oxygen content (7±1mg / L) and temperature (20±3℃) of the water are the same for the two breeding methods, and the breeding density is 20 per m 3 , sea bass were fed twice a day (9:00 and 17:00), with the same amount of food each time, and the amount of food was increased synchronously with the increase in weight.

[0138] 3. Collection Methods

[0139] Sampling was performed after 7 months of culture until adulthood, and the seabass were starved for 24 hours before sampling. Then, 20 seabass with roughly the same body length and weight were randomly selected from each culture method (average weight: 600±15g). The seabass were dissected after anesthesia with MS-222, and the muscles were removed from their backs, numbered, and stored in a -20℃ refrigerator for testing.

[0140] 4. Instruments used

[0141] Weighing balance; muffle furnace; DHG-9036A electric constant temperature blast drying oven (Shanghai Jinghong Experimental Equipment Co., Ltd.); electric constant temperature water bath; KjelFlex K-360 fully automatic nitrogen analyzer (FOSS Analytical Instruments, Denmark); Soxhlet extractor; Agilent 7890N gas chromatograph: equipped with a hydrogen flame ionization detector (FID) (Agilent Technologies Co., Ltd.); SYKAM S-433D amino acid analyzer (SYKAM, Germany).

[0142] 5. Analytical methods

[0143] The moisture, crude ash, crude protein, crude fat, amino acid and fatty acid contents in muscle were determined by direct drying method (GB / T5009.3-2016), muffle furnace combustion method (GB / T5009.4-2016), Kjeldahl nitrogen determination method (GB / T5009.5-2016), Soxhlet extraction method (GB / T5009.6-2016), high performance liquid chromatography (GB / T5009.124-2016) and gas chromatography (GB / T5009.168-2016), respectively.

[0144] 6. Evaluation of the nutritional value of muscle amino acids

[0145] The amino acid score (AAS), chemistry score (CS) and essential amino acid index (EAAI) were calculated according to the amino acid score standard model recommended by the Food and Agriculture Organization / World Health Organization (FAO / WHO) in 1973 and the amino acid model of whole egg protein using the following formulas:

[0146]

[0147] Where: aa——amino acid content in sea bass muscle (amino acid content unit is mg / gPro, the same below);

[0148] AA (FAO / WHO) – the content of the same amino acid in the scoring model;

[0149] AA(Egg)——the content of the same amino acids in whole egg protein;

[0150] a, b, c…, j – essential amino acid content of sea bass muscle protein;

[0151] ae, be, ce…je – the essential amino acid content of whole egg protein.

[0152] 7. Data Analysis

[0153] The experimental data were statistically analyzed using Excel, and SPSS27 was used for one-way ANOVA and Duncan's multiple comparisons. Figure 6 and Figure 7 The results are presented, where * indicates significant difference (P<0.05).

[0154] It should be noted that, through the experimental study of the above test examples, it can be found that after using the Chinese herbal feed additive of the present application in the process of sea bass farming, the nutritional components of sea bass muscle have changed significantly: the ash and crude protein content have increased significantly, and the moisture and crude fat have decreased (as shown in Table 1); the essential amino acid content and the total amino acid content have increased significantly, EAA / TAA has increased by 4.8%, and EAA / NEAA has increased by 9.1% (as shown in Table 2). Figure 6 ); AAS, CS and EAAI scores were also significantly improved (as shown in Table 2). In addition, the fatty acid composition ratio was significantly optimized, with the proportion of saturated fatty acids in the total fatty acids decreasing from 33.71% to 31.55%, the proportion of unsaturated fatty acids increasing from 66.29% to 68.45%, the proportion of monounsaturated fatty acids increasing from 12.76% to 14.25%, and the proportion of polyunsaturated fatty acids increasing from 53.53% to 54.20% (as shown in Table 2). Figure 7 ).

[0159]

[0160]

[0161] In summary, it can be seen from the test examples of the present invention that the addition of the Chinese herbal feed additive of the present invention to the feed for seabass farming can increase the ash and crude protein content of seabass and reduce the moisture and crude fat; the increase in ash content brings more abundant inorganic components such as minerals, and the increase in crude protein consolidates the status of high-quality protein source, which is beneficial to growth and muscle development, while the reduction in moisture and crude fat optimizes the meat quality and fat structure, reduces the risk of fat intake, and improves the taste and flavor. In addition, in terms of amino acid composition, the essential amino acid content and total amino acid content of seabass are significantly improved after adding Chinese herbal feed additives, and the EAA / TAA and EAA / NEAA ratios are more reasonable, the AAS and CS scores of isoleucine, valine, leucine and lysine are increased, and the EAAI score is also significantly improved, indicating that Chinese herbal feed additives have a regulatory effect on the amino acid composition in seabass muscle and improve the nutritional value of protein.

[0162] Furthermore, in terms of fatty acid composition, the addition of Chinese herbal feed additives reduced the proportion of saturated fatty acids and increased the proportion of unsaturated fatty acids, especially the content of monounsaturated fatty acids and polyunsaturated fatty acids increased, the mass fraction of DHA and EPA increased, and the ΣPUFAn3 / ΣPUFAn6 ratio increased significantly, thereby optimizing the fatty acid composition ratio and improving the nutritional value of lipids.

[0163] Furthermore, with regard to the processing equipment for Chinese herbal feed additives provided by the present invention, when the feed enters the receiving bag through the sleeve tube, the weight of the feed in the receiving bag gradually increases, so that the receiving bag pulls the sleeve tube downward until it reaches the carrying capacity of the receiving bag, so that the sleeve tube is pulled downward, and the sleeve tube pulls the two docking clamping rods out of the two docking clamping slots. The movement of the sleeve tube drives the edge sealing disk to rotate, and the rotation of the edge sealing disk drives the other sleeve tube to dock with the discharge pipe, thereby completing the switching of the receiving bag, thereby realizing automatic switching of the receiving bag, and at the same time, the sleeve tube and the discharge pipe can be automatically docked. At this time, you only need to remove the receiving bag filled with feed and replace it with a new one. When switching, there is no need to shut down the processing host, which effectively improves the processing efficiency and ensures the production quality of the feed.
