Embodiment 1

[0030] Take 0.00008 parts by weight of thiamine, 1.4 parts by weight of valine, 0.76 parts by weight of histidine, and 0.0018 parts by weight of manganese, and mix them to prepare feed additive D1.

[0031] In order to verify the application effect of the present invention, the feed additive of the present invention was tested on grass carp (body weight 279-281g) in 10 farms in Sichuan, Chongqing and Guangxi. The test fish were equally divided into two groups, the test group and the control group, and each treatment group had 3 replicates, with 400 fish per replicate, and there was no significant difference in the initial body weight between the groups. The diet of the test group was fish feed added with the above-mentioned feed additive D1 according to 2.1wt% of the total weight of the fish feed; the diet of the control group was fish feed of the same weight without adding the additive D1. The fish in the two treatment groups were fed 4 times a day, and the amount of each fee...

Embodiment 2

[0042] Take 0.0002 parts by weight of thiamine, 2.0 parts by weight of valine, 0.37 parts by weight of histidine, and 0.0008 parts by weight of manganese, and mix them to prepare feed additive D2.

Embodiment 3

[0044] Take 0.00004 parts by weight of thiamine, 0.8 parts by weight of valine, 0.98 parts by weight of histidine, and 0.0027 parts by weight of manganese, and mix them to prepare feed additive D3.

Abstract

The invention discloses an additive for improving cultured fish meat quality, a use method, application and fish feed. The additive for improving the cultured fish meat quality comprises the following components by weight: 0.00004-0.0002 part of thiamine, 0.8-2.0 parts of valine, 0.37-0.98 part of histidine, and 0.0008-0.0027 part of manganese. By adding the additive in the range, the fish muscle water-holding capacity, chewiness and pH can be enhanced, the sensory quality of fish can be improved, and at the same time, fish growth can be promoted, and the feed efficiency can be improved. The additive has the advantages of convenient use, low cost, no toxicity and safety, etc.

Description

technical field [0001] The invention belongs to the field of freshwater fish culture, and in particular relates to an additive for improving the meat quality of cultured fish, a use method, application and fish feed. Background technique [0002] Fish meat is rich in high-quality protein, easy to digest and absorb, low in fat, and also contains calcium, phosphorus, potassium, iodine, zinc, selenium and other inorganic salts, as well as vitamin A, vitamin D and B vitamins. Therefore, fish products are one of the important meat products to improve dietary structure and improve human health. With the improvement of people's living standards, consumers' demand for aquatic products is getting higher and higher. Grass carp, carp and other freshwater fish are the main farmed fish in my country. They have a long history of farming, and their farming output is high, accounting for 33-40% of the total fish farming output, which greatly meets people's demand for animal protein. [00...
