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 bread worms, white ants, fly maggots, silkworm pupae, sieve to remove dead, rigid and broken pupae and other fiber impurities, crush, finely grind and siev to obtain 80 mesh fine protein, set aside;

[0018] b. According to 18% of bread worms, 15% of white ants, 18% of fly maggots, 14% of silkworm pupae, 13% of eggs, 5% of millet, 5% of algae powder, 5% of soybean oil, 5% of scutellaria, 2% of white radish, Garlic 5% by mass is weighed as the raw materials; the millet, algae powder, and scutellaria are crushed through an 80-mesh sieve, white radish and garlic are air-dried and pulverized through an 80-mesh sieve, and they are combined with the fine protein and 6% soybean oil described in step a. Put it into the mixer and mix for 5 minutes to make it evenly mixed;

[0019] c. The mixed raw materials are added to the whole egg and crushed again, so that all the components can pass through a 90-mesh sieve, the crushed materials are passed through 85℃ steam for condition...

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-based rainbow trout feed, belonging to the field of feed processing, in particular to an insect-based 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 them are rich in nutrients and high in protein. They can be used to replace concentrated feed to feed livestock and poultry to increase breeding yield and economic benefits. [0003] For a long time, the research on insects has focused on the prevention and control of pests. The nutritional physiology of insects has also been carried out from the perspective of the impact of insect feeding on plants. With the rapid development of the aquaculture industry, fish feed nutrition analysis shows If insects are used as fish feed, the nutritional structure contained in the insects is reasonable, contains high protein, chitin (chitosan) and fatty acids...
