Embodiment 1

[0011] A feed additive for improving cold-water fish meat quality. The additive includes the following components and their parts by weight: 15-30 parts of Eucommia ulmoides, 10-25 parts of Baizhu, 10-30 parts of Chinese Yam, 5-15 parts of Radix Isatidis, 10-20 parts of Angelica, 5-10 parts of licorice, 0.5-1 part of Eclipta prostrata, and 0.1-0.5 part of Yanshuangbai, improve the meat quality of cold water fish and make cold water fish delicious. Among them, Eclipta and Yanshuangbai can prevent the additives from affecting the quality of cold water fish. It also has the effect of promoting the sensory effect of meat texture. The meat is tender, smooth and white in color. It enhances immunity while increasing the growth rate of cold water fish, promotes cold water fish digestion and disease resistance, thereby improving its feed utilization rate and slowing down cold water fish Stress response.

Embodiment 2

[0014] A feed additive for improving the meat quality of cold water fish. The additive includes the following components and their parts by weight: 30 parts of Eucommia ulmoides, 20 parts of Atractylodes, 15 parts of Chinese Yam, 5 parts of Radix Isatidis, 10 parts of Angelica, 5 parts of Licorice, 0.5 parts of Eclipta sinensis, 0.1 part of salt frost cypress.

[0015] A preparation method of feed additive for improving cold water fish meat quality, the preparation steps are as follows:

[0016] 1) Weigh by weight: Eucommia ulmoides, Atractylodes macrocephala, Chinese yam, Radix Isatidis, Angelica sinensis, Licorice root, Eclipta prostrata, Cypress cypress, dry, crush to 70 meshes to obtain the dry powder of raw materials;

[0017] 2) Mix the dry powder of the raw material drug uniformly, add water to soak, and ultrasonic aid, the ultrasonic power is 200~300w, the time is 10~15min, the amount of water added is 30 times the volume of the dry powder of the raw material drug, the soakin...

Embodiment 3

[0022] Select 400 cold-water fish fry and use 100 as a group to establish four experimental groups. Weigh 30 parts of Eucommia ulmoides, 20 parts of Baizhu, 25 parts of Chinese yam, 10 parts of Radix Isatidis, 15 parts of Angelica sinensis, and licorice according to the above additives and weight parts. 7 parts, 0.5 parts of Eclipta prostrata and 0.5 parts of S. cypress are made into 1 kg of additives, and they are added to the special feed for freshwater and cold water fish at 5%, 10%, and 15% respectively to configure the experimental feed, and will not contain The cold water fish feed with this additive was used as a control feed. The three experimental groups were fed with 5%, 10%, and 15% additive experimental feeds, and the remaining group was raised with control feeds without this additive, and fed 4 times a day. The results after 4 weeks are shown in Table 1 below:

Abstract

The invention provides a feed additive for improving the fish quality of cold water fish and an application of the feed additive. The additive comprises the following components in parts by weight: 15-30 parts of cortex eucommiae, 10-25 parts of bighead atractylodes rhizomes, 10-30 parts of dioscorea opposita, 5-15 parts of radix isatidis, 10-20 parts of radix angelicae sinensis, 5-10 parts of licorice roots, 0.5-1 part of red lotuses and 0.1-0.5 part of roots, leaves and fruits of rhus chinensis. According to the feed additive disclosed by the invention, the meat quality of the cold water fish can be improved, and the meat quality of the cold water fish can be delicious; the red lotuses and the roots, leaves and fruits of rhus chinensis can avoid the additive from influencing the meat quality of the cold water fish, and have the effect of promoting the sense organ effects of the meat quality, the meat quality is tender and smooth and white in color, the growth speed of the cold water fish is increased, the immunity can be enhanced, the digestive capacity and the disease resistant capacity of the cold water fish can be promoted, the utilization rate of a feed can be increased, and besides, stress response to the cold water fish is retarded.

Description

Technical field [0001] The invention relates to a feed additive for aquaculture, in particular to a feed additive for improving cold water fish meat quality and its application. Background technique [0002] In recent years, with the rapid development of the aquaculture industry and the popularization of intensive aquaculture methods, the total amount of aquaculture in my country has continued to increase. However, cold-water fish generally exhibit shortcomings such as soft meat and poor taste, which greatly increases the cost of food, consumption, processing and utilization of cold-water fish, which seriously restricts the healthy development of cold-water fish farming economy. With the improvement of people's living standards, people also put forward higher requirements for the meat quality of cold water fish. [0003] In the existing aquaculture, in order to enhance the cultivation of cold water fish, many technologies are provided, such as a cold water fish feed, CN102715364A,...
