Problems solved by technology

Although this kind of feed can provide nutrients, its crude protein content is about 35% to 18%, which cannot fully meet the crude protein needs of fish; and its function is single, and it has no special function in the prevention and treatment of rainbow trout.

Embodiment 1

[0017] a. Take mealworms, white ants, fly maggots, silkworm chrysalis, sieve to remove dead, stiff and bad chrysalis and other fiber impurities, pulverize, finely grind and sieve to obtain 80 mesh fine protein, stand-by;

[0018] b. According to mealworm 18%, white ants 15%, fly maggot 18%, silkworm chrysalis 14%, egg 13%, millet 5%, algae powder 5%, soybean oil 5%, radish seed 5%, white radish 2%, 5% mass percent of garlic is weighed raw materials; pulverized broomcorn millet, algae powder, and radish are passed through an 80-mesh sieve, air-dried and crushed white radish and garlic are passed through an 80-mesh sieve, and put them together with the fine protein described in step a and 6% soybean oil. Mix in a mixer for 5 minutes to make it evenly mixed;

[0019] c. Add whole eggs to the mixed raw materials and crush them again so that all components can pass through a 90-mesh sieve. The crushed materials are passed through steam at 85°C for 10 minutes, and then the raw mater...

Abstract

Belonging to the feed processing field, the invention relates to insect rainbow trout feed, especially a preparation method of rainbow trout feed with insects as raw materials. The feed is characterized by comprising, by weight: 15-20% of Tenebrio molitor, 15-20% of termites, 15-20% of fly maggots, 15-20% of silkworm chrysalises, 15-20% of eggs, 3-6.5% of prosomillet, 2-5% of alga powder, 4-8% of soybean oil, 2-3% of white radishes, 2-8% of radish seeds, and 2-8% of garlic. The feed of the invention has the advantages of high animal protein content, comprehensive nutrition necessary for promoting rainbow trout growth, strong feeding attraction, high digestibility, gut immunity improvement, virus and disease prevention, good stability in water, difficult pollution to aquaculture water quality, no peculiar smell, no organic residual, better application security, and broader application prospects.

Description

technical field [0001] The invention relates to an insect-derived rainbow trout feed, which belongs to the field of feed processing, in particular to an insect-derived rainbow trout feed and a preparation method thereof. Background technique [0002] At present, there are more than 500 species of insects that can be used as feed in the world, many of which are rich in nutrients and high in protein content, and can be used to replace concentrated feed to feed livestock and poultry, improving breeding production and economic benefits. [0003] For a long time, research on insects has focused on the prevention and control of pests, and research on the nutritional physiology of insects has mostly been carried out from the perspective of the impact of insect feeding on plants. With the rapid development of the aquaculture industry, the nutritional analysis of fish feed shows that , if insects are used as fish feed, the nutritional structure contained in the insects is reasonable,...
