Embodiment 1

[0014] Example 1 : A feed additive for improving the disease resistance of grass carp and improving the flavor of meat, consisting of the following components in mass percentage: 12% Coptis chinensis, 12% pine needle powder, 11% dandelion, 12% lettuce, silver 8% vine, 8% astragalus, 6% forsythia, 7% anise, 8% cassia twig, 6% cinnamon, 2% inosinic acid, 3% guanylic acid, 5% carnitine; the preparation method includes the following steps: Weigh each component according to the mass percentage, and crush the Chinese herbal medicines such as coptis, pine needle powder, dandelion, lettuce, silver flower vine, astragalus, forsythia, anise, cinnamon stick and cinnamon to about 60-80 mesh , and then mix it with inosinic acid, guanylic acid and carnitine.

Embodiment 2

[0015] Example 2 : A feed additive for improving the disease resistance of grass carp and improving the flavor of meat. It is composed of the following components in mass percentage: Coptis chinensis 10%, pine needle powder 12%, dandelion 12%, lettuce 11%, silver 5% vine, 15% astragalus, 5% forsythia, 6% anise, 6% cassia twig, 8% cinnamon, 2% inosinic acid, 3% guanylic acid, 5% carnitine; the preparation method includes the following steps: Weigh each component according to the mass percentage, and crush the Chinese herbal medicines such as coptis, pine needle powder, dandelion, lettuce, silver flower vine, astragalus, forsythia, anise, cinnamon stick and cinnamon to about 60-80 mesh , and then mix it with inosinic acid, guanylic acid and carnitine.

Embodiment 3

[0016] Example 3 : Animal feeding test

[0017] In a freshwater fish farm in Hunan, 2,000 grass carp with basically the same growth conditions were selected and randomly divided into five groups. They were cultured in cages, with 100 fish in each cage, and fed green grass and some compound feeds. Add different additive components in the feed, group 1 is the blank control group, its compound feed adds 2% corn gluten powder; 2 special feed additive for grass carp; groups 4 and 5 are comparative test groups, add 2% of the feed additives of the following comparative test examples 1 and 2 respectively in its compound feed, feed for 3 months, record the incidence of disease during the period and the final survival rate. The specific results are shown in Table 1:

Abstract

The invention relates to a feed additive for improving disease resistance of grass carps and improving meat quality and flavor, which is formed by the following components in mass percentage: 10-15% of rhizoma coptidis, 10-15% of pine needle meal, 10-12% of dandelion, 10-15% of endives, 5-15% of honeysuckle stems, 5-15% of astragalus mongholicus, 5-8% of fructus forsythiae, 5-10% of anise, 5-10% of cassia twig, 5-10% of cinnamon, 2% of inosinic acid, 3% of guanylic acid and 5% of carnitine; and the sum of the weight percentages of all the raw materials is 100%. With the adoption of the feed additive for improving the disease resistance of the grass carps and improving the meat quality and the flavor, the economic benefits of the cultivation of the grass carps can be obviously improved, four diseases of grass carp in a grass carp cultivation process can be obviously improved, and the survival rate is improved by 6-8%; the feed conversion rate in the grass carp cultivation process can be effectively improved and the growth of the grass carps is accelerated; and with the adoption of the feed additive disclosed by the invention, the mouth feel and the quality of the grass carps are obviously better than the condition without the feed additive, and the flavor and the mouth feel of the grass carps are close to those of wild grass carps.

Description

technical field [0001] The invention relates to a feed additive for aquaculture, in particular to a feed additive for grass carp which improves disease resistance and meat quality and flavor of grass carp. Background technique [0002] Grass carp is one of the four major domestic fishes in my country, and it is also the main freshwater fish species in my country. Grass carp farming has the advantages of low feed cost and obvious economic benefits, and it is very popular among consumers for its tender meat, large individuals, and few intermuscular spines. . In recent years, with the development of the aquaculture industry, grass carp farming has become a traditional grass feed feeding method, which has been transformed into a feeding method based on concentrate and supplemented by green feed. The growth period of grass carp has also been shortened from two years to one year. The economic benefits have been significantly improved, but due to the high-density breeding condition...
