preparation example Construction

[0092] Therefore, in a preferred embodiment of the present invention, the preparation method of the additive composition provided by the present invention may comprise the following steps:

[0093] 1) mixing the above plant extracts in proportions by weight with activated carbon and other selected functional additives;

[0094] 2) Compress and granulate under the condition of 30°C-65°C.

[0095] In step 1) of the above method, one or more other functional additives mentioned above may be added as required, mixed together, and then compressed into granules.

[0096] In step 2), the pressing temperature is preferably 40°C-45°C. Tests have shown that the temperature and pressing operation in step 2) will not affect the activity of the complex enzyme.

[0097] Wherein, the plant extract can be prepared by conventional extraction and drying methods using conventional extraction solvents, such as water and ethanol. For example, extraction may be carried out by decocting in water,...

experiment example 1

[0118] Experimental location: Dagongcheng, Cuihuangkou, Wuqing District; Experimental time: August 21, 2010 to October 22, 2010; Breeding mode: Grass carp nested with crucian carp and silver carp.

[0119] The experimental group used the additive of the present invention (hereinafter referred to as Paidu Sanxiaokang, see Example 6 for the specific formula and preparation method) while the control group did not use the additive of the present invention. The specific experimental results are shown in Table 2 and Table 3. It can be seen from the observation during the experiment that after feeding the additive of the present invention, the fish has good fur and stress tolerance; In addition, since the feed coefficient is obviously reduced after feeding the additive of the invention, the economic benefit can be improved.

experiment example 2

[0125] Experimental site: Longgan Lake, Qi County, Hubei; experimental time: August 12, 2010 to September 11, 2010; breeding mode: grass carp interbreeding with bream and silver carp.

[0126] The experimental group (addition group) used the additive of the present invention (see Example 7 for the specific formula and preparation method), while the control group (non-addition group) did not use the additive of the present invention.

[0127] Figure 1A with Figure 1B Microphotographs of grass carp intestine wall in the unsupplemented group and the supplemented group, respectively. It can be seen from the photos that the muscular layer of the intestinal wall in the non-supplemented group became thinner, the muscle fibers were loosely arranged, the villous epithelial cells were arranged in disorder, and the goblet cells were less; Neatly arranged and clearly outlined.

Abstract

The invention provides an aquatic product feed additive composition, a preparation method and application thereof. The composition comprises the following raw materials in parts by weight: 30-45 parts of plant extract and 5-10 parts of montmorillonite, wherein the plant extract is prepared from the bulk pharmaceutical chemicals in parts by weight: 6-18 parts of wormwood, 6-18 parts of mintkit, 6-18 parts of astragalus root, 5-15 parts of white paeony root and 5-15 parts of fleece-flower root. The additive composition has the advantages of being good in palatability, enhancing animal appetite,improving fish intestinal tract functions, maintaining long-term health of fish alimentary canals, promoting digestive absorption of fishes, increasing fish organism immunocompetence, and strengthening health and stress resistance capacity; and after excrement enters a water body, water quality can be continuously improved, and problem of water degradation is relieved.

Description

technical field [0001] The invention relates to a feed additive composition, in particular to an aquatic feed additive composition and its preparation method and application. Background technique [0002] At present, in the aquaculture industry, there are many factors affecting the breeding efficiency, which mainly cause the following problems. [0003] First of all, the intestinal health problems of aquatic animals will affect the breeding efficiency. Under the conditions of strong changes in internal and external environments such as temperature and dissolved oxygen in aquatic animals, intestinal capillaries are prone to congestion, intestinal epithelium is inflamed, intestinal villi epithelial cells are exfoliated and necrotic, intestinal villi and microvilli are damaged, the digestive capacity of intestinal mucosa is reduced, and overfeeding is serious , Malnutrition, decreased resistance, invasion of harmful pathogens and massive proliferation, resulting in thinning of...
