Embodiment 1

[0020] Weigh 99.85% tea seed cake, vitamin E0.05, vitamin C0.05%, selenium 0.05% by weight percentage;

[0021] Prepare the feed additive as follows: crush the tea seed cake into 120-mesh powder, mix the tea seed cake powder, vitamin E, vitamin C and selenium, use wet granulation to make additive granules with a size of 20 mesh, Using a fluidized bed coating device, use 4% aqueous solution of hydroxypropyl cellulose as coating on the outside of the additive granules at a temperature of 38° C. and dry for 20 minutes. The weight ratio of the additive granules to hydroxypropyl cellulose is 100:3.

Embodiment 2

[0023] Weigh 99.2% tea seed cake, vitamin E 0.25%, vitamin C 0.26%, selenium 0.29% by weight percentage;

[0024] Prepare the feed additive as follows: crush the tea seed cake into 110-mesh powder, mix the tea seed cake powder, vitamin E, vitamin C and selenium, use wet granulation to make additive granules with a size of 20 mesh, Using a fluidized bed coating device, a 6% aqueous solution of hydroxypropyl cellulose was used as a coating on the outside of the additive granules at a temperature of 40° C. and dried for 20 minutes. The weight ratio of the additive granules to hydroxypropyl cellulose was 100:4.

Embodiment 3

[0026] Weigh 99.7% tea seed cake, vitamin E 0.1%, vitamin C 0.1%, selenium 0.1% by weight percentage;

[0027] Prepare the feed additive as follows: crush the tea seed cake into 100-mesh powder, mix the tea seed cake powder, vitamin E, vitamin C and selenium, use wet granulation to make additive granules with a size of 20 mesh, Using a fluidized bed coating device, a 5% aqueous solution of hydroxypropyl cellulose was used as a coating on the outside of the additive granules at a temperature of 42° C. and dried for 20 minutes. The weight ratio of the additive granules to hydroxypropyl cellulose was 100:5.

Abstract

The invention discloses a feed additive for promoting fish growth. The feed additive comprises the following raw materials in percentage by weight: 99.2-99.9 percent of tea seed cake, 0.05-0.3 percent of vitamin E, 0.05-0.3 percent of vitamin C and 0.05-0.3 percent of selenium. A preparation method of the feed additive comprises the following steps: grinding the tea seed cake until the mesh number is 100-120; uniformly stirring tea seed cake powder, the vitamin E, the vitamin C and the selenium in percentage by weight to prepare coated particles, and sieving the coated particles through a 20-mesh sieve. With the adoption of the feed additive, the fish growth can be effectively promoted, the preparation process is simple, and the tea seed cake does not need to be detoxified. The feed additive is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of feed additives and relates to a feed additive for promoting fish growth. Background technique [0002] Both tea and Camellia oleifera are plants of the genus Camellia in the family Theaceae, and both seeds contain oil with high nutritional value. Tea seed cake is the product left after tea seeds are pressed or leached to extract most of the oil, also known as tea dead, tea bran. As a big planting country of tea and Camellia oleifera, my country is rich in tea seed cake resources, with an annual output of about 400,000 tons of tea oil cake, which is rich in various active ingredients such as tea saponin, protein, fat and sugar , but the current utilization of tea seed cake is still insufficient. [0003] The content of tea saponin in tea seeds can reach up to 10-14%. Tea saponin is a pentacyclic triterpenoid glycoside compound extracted from the Theaceae plant. It exists widely in various tea plants. Its ...
