Problems solved by technology

[0009] The published related patents mainly use taurine to improve fish liver function and enhance immune function by combining taurine with immune enhancers or Chinese herbal medicines. It is necessary to take corresponding measures to achieve a certain effect, the technique is difficult to use, the operation is complicated, and long-term continuous use may also cause the potential risk of immunosuppression
[0010] In summary, some technical schemes using taurine as a feed additive to promote food intake and growth of farmed fish or to enhance the immune function of the body have been proposed at present. These technical schemes have solved the deficiencies in the prior art to a certain extent, but , the role of taurine as a biologically active substance in the antioxidant and lipid-lowering aspects of fish has not been reported

Embodiment 1

[0029] Embodiment 1: grouper is prepared with taurine compound preparation

[0030] The raw materials are shown in Table 1;

[0031] The table of raw materials (parts by weight) used in the taurine compound preparation for each grouper of table 1

[0032]

[0033] Preparation method: Weigh each raw material according to the compatibility, put it into a blender and mix well, and then obtain the taurine compound preparation for grouper.

Embodiment 2

[0035] Table 2 is the basal feed formulation and nutrient composition table.

[0036] Table 2 Basic Feed Formula and Nutrient Composition Table

[0037]

[0038]

[0039] When preparing the test feed, add the grouper taurine compound preparation (prepared with the grouper taurine compound preparation 3) with the ratio of 1%, 1.5%, and 2% respectively, and correspondingly reduce the microcrystalline in Table 2 The proportion of cellulose.

[0040] Using casein and gelatin (4:1) as protein source, fish oil, soybean oil and soybean lecithin as fat source, cornstarch as starch source, and crystalline cellulose as filler, a taurine-free compound preparation was prepared The basal feed (contrast feed), then, grouper is added in the basal feed with the taurine compound preparation by 1%, 1.5%, 2% ratio and correspondingly reduces the ratio of microcrystalline cellulose in Table 2 simultaneously, is mixed with Two kinds of test materials (feed 1, feed 2, and feed 3) with diffe...

Abstract

The invention discloses a taurine compound preparation for grouper and its application. It consists of the following raw materials in parts by weight: 30-70 parts of taurine, 10-40 parts of alanyl glutamine, 2-6 parts of vitamin C polyphosphate, 1-5 parts of vitamin E, 4-40 parts of corn starch 19 servings. The taurine compound preparation for grouper has the functions of promoting the growth and feed conversion efficiency of grouper, reducing the ratio of liver to body, reducing the body fat and liver lipid deposition of grouper, and obviously improving the superoxidation in the liver and plasma of grouper. Dismutase, catalase, serum antioxidant enzymes, glutathione peroxidase activity and total antioxidant capacity, while significantly reducing the effect of malondialdehyde content.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and relates to the application of taurine compound preparations in grouper feed, in particular to the use of taurine compound preparations for grouper in grouper feed to reduce body fat deposition in grouper and improve body resistance. The role of oxidative capacity. Background technique [0002] With the rapid development of intensive and industrialized aquaculture in my country, various unfavorable aquaculture environmental conditions and factors have become important constraints affecting the normal growth of farmed fish. At present, in aquaculture production, due to the change of aquaculture environment conditions, the cultured fish are in a state of stress, which leads to low metabolic function of the body, decline in production performance, and even diseases. Among them, the most representative symptom is a nutrient metabolism. Disease - fatty liver. The diseased fish manifested as decreased ...
