Problems solved by technology

[0006] Ester, soybean oil, and zeolite powder are uniformly mixed to prepare a feed additive for reducing the fat content of freshwater fish, which has the advantages of easy method and simple operation. However, the inventive method is to prevent related diseases induced by excessive fat accumulation in freshwater fish culture. It is not advisable to choose to reduce the body fat of freshwater fish because it will cause the fish not to like to eat and grow slowly, and reducing the fat content will also reduce the economic value of freshwater fish

Embodiment 1

[0020] Feed-inducing and growth-promoting additive for freshwater aquaculture fish, its composition and parts by weight are: 20 parts of modified fish oil, 5 parts of lecithin, 25 parts of fish protein hydrolyzate, 1.0 part of enzyme preparation, 2.0 parts of food attractant, growth-promoting 1.5 parts of traditional Chinese medicine preparations, 2.0 parts of traditional Chinese medicine preparations, and 0.3 parts of active polypeptides; freshwater cultured fish feed attractant and growth-promoting additives are comprehensive in nutrition and reasonable in proportion. Growth-promoting additives can also improve the composition of lipids and fatty acids in fish, improve the immunity and stress ability of fish, increase the activity of lipase and amylase in the liver and digestive tract of fish, and promote the digestion and absorption of bait by fish. Promote growth, shorten the breeding cycle, and reduce the cost of breeding.

Embodiment 2

[0024] The feed-attracting and growth-promoting additive for freshwater aquaculture fish, the preparation method of which comprises the following steps:

[0025] 1) Preparation of traditional Chinese medicine preparations: crush 5 parts of Codonopsis pilosula, 6 parts of honeysuckle, 3 parts of hawthorn, 6 parts of Divine Comedy, 10 parts of Atractylodes macrocephala, and 6 parts of Chinese herbal medicine. Traditional Chinese medicine compound preparation, wrapped with absorbent cotton yarn, added 12 times of distilled water, soaked for 2 hours, boiled, decocted for 40 minutes, filtered with gauze, decocted the filter residue, mixed the filtrate, concentrated at low temperature to 25 %, stored at 4°C for later use; Chinese medicine preparations can enhance the disease resistance and antibacterial ability of fish, improve the body's immunity, and enhance physical fitness, and the unique taste of Chinese medicine preparations is conducive to enhancing the food-attracting ability...

Embodiment 3

[0030] Feed-inducing and growth-promoting additive for freshwater aquaculture fish. The composition and parts by weight of the additive are: 24 parts of modified fish oil, 8 parts of lecithin, 28 parts of fish protein hydrolyzate, 1.4 parts of glucanase, and 2.8 parts of seaweed extract powder 2.4 parts of earthworm powder, 2.8 parts of traditional Chinese medicine preparations, and 0.4 parts of active polypeptide; freshwater aquaculture fish feed attractant growth-promoting additives are comprehensive in nutrition and reasonable in proportion, and can resist disease and antibacterial while stimulating and attracting fish to eat more Growth-promoting additives can also improve the composition of lipids and fatty acids in fish, improve the immunity and stress ability of fish, increase the activity of lipase and amylase in the liver and digestive tract of fish, and promote the fish's ability to bait. Digest and absorb, promote growth, shorten the breeding cycle and reduce the cos...

Abstract

The invention discloses a fresh water cultured fish feed calling growth promoting additive, which comprises the following components in parts by weight: 20-25 parts of modified fish oil, 5-10 parts oflecithin, 25-30 parts of fish protein hydrolysate, 1.0-1.5 parts of enzymic preparation, 2.0-3.0 parts of food attractants, 1.5-2.5 parts of growth promoter, 2.0-3.0 parts of traditional Chinese medicine preparation, and 0.3-0.5 part of active polypeptide. The fresh water cultured fish feed calling growth promoting additive has the beneficial effects that the calling growth promoting additive iscomplete in nutrients, can stimulate and attract fish to increase feeding, can also improve the in-vivo lipid and fatty acid composition of fish, and enhance the immunocompetence and stress capabilityof fish; and the additive can improve the digestion function of fish, improve the activity of lipase and amylase in liver and digestive tract, promote the digestion and absorption of fish to baits, and lower the culturing cost, thus being a high-efficiency and scientific fresh water cultured fish feed calling growth promoting additive.

Description

technical field [0001] The invention relates to the field of aquatic feed additives, in particular to a food-inducing and growth-promoting additive for freshwater aquaculture fish feed. technical background [0002] Broadly speaking, fish that can live in fresh water with a salinity of three thousandths can be called freshwater fish. In a narrow sense, it refers to fish that have only "juvenile stage" or "adult fish stage" in some stages of their life history, or fish that must spend their entire life in fresh water. There are more than 26,000 known species of fish in the world, which is the most diverse group of vertebrates, accounting for about 48.1% of the total number of vertebrates. Most of them live in the ocean, and there are about 8,600 species of freshwater fish. There are nearly 3,000 species of fish in my country, including more than 1,000 species of freshwater fish. Among the freshwater fish in our country, some species are widely distributed and can be seen a...
