Abstract

The invention discloses a feed capable of promoting black sea bream growth and a preparation method thereof. The feed capable of promoting black sea bream growth is prepared from the following ingredients in parts by weight: 8-25 parts of fish meal, 10-24 parts of soybean meal, 35-45 parts of concentrated soybean protein, 10-15 parts of high-gluten flour, 4-12 parts of whole krill meal, 3-5 parts of fish oil, 2-8 parts of corn oil, 1-2 parts of soybean phospholipids, 1 -2 parts of disodium hydrogen phosphate, 0.3-1.5 parts of compound vitamins, 0.5-1 part of compound minerals, 0.01-0.1 part of konjac glucomannan, 0.01-0.1 part of betaine hydrochloride, 0.1-0.5 part of chloride choline, 0.01-0.8 part of betaine, 0.1-0.3 part of compound enzyme preparations, and 0.1-0.3 part of compound amino acids. The invention further provides a preparation method of the feed capable of promoting black sea bream growth; and the feed prepared according to the preparation method is high in nutrition utilization rate, and low in feed coefficient. The feed capable of promoting black sea bream growth disclosed by the invention is environmentally friendly, and economical in feed cost.

Description

technical field [0001] The invention relates to a feed, in particular to a feed for promoting the growth of black sea bream and a preparation method thereof. Background technique [0002] The black snapper is oblong, with flat sides, gray-black back, silver-white and shiny belly, hard spines on the dorsal fin, especially the spines on the second anal fin, except for the gray pectoral fin, the edges of the rest of the fins are black.

Problems solved by technology

[0004] Prior art such as Chinese Invention Authorized Patent Literature, Authorized Notice No. CN103931913B, the invention discloses a snakehead formula feed, which is made of the following raw materials in parts by weight: 20-25 parts of sorghum flour, 15-20 parts of corn flour, bean cake 20-25 parts, 10-14 parts of fish meal, 4-5 parts of snail powder, 3-4 parts of lotus root powder, 5-9 parts of spinach root, 5-8 parts of celery root, 2-3 parts of walnut kernel, 4-5 parts of tea tree flower part, 2-3 parts of Phellodendron cortex, 10-12 parts of water hyacinth, 5-6 parts of mustard mustard, 8-10 parts of milk, 3-5 parts of food attractant, appropriate amount of water; It has the advantages of simple production process, low cost, easy access to ingredients, and rich nutrition. It is rich in fat, carbohydrates, protein, vitamins, crude fiber, and minerals. It meets the growth needs of snakeheaded fish. The nutrient composition can promote the growth and development of snakeheaded fish and reduce the incidence of snakeheaded fish. However, the feed is lacking in the addition of compound minerals, which is not conducive to improving the immunity of snakeheaded fish. There is still room for improvement in improving the meat quality of snakeheaded fish
