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

A kind of worm source property rainbow trout feed and preparation method thereof

Technical field

The present invention relates to a kind of insect property rainbow trout feed, belong to field of feed processing, specifically a kind of worm source property rainbow trout feed and preparation method thereof.

Background technology

The insect that can make in the world at present feed has more than 500 to plant, and wherein has many kinds of insects nutritious, and protein content is high, can be used for replacing concentrated feed to feed livestock and poultry, improves cultured output and economic benefit.

For a long time, for the research of insect take the control of pest type as main, the nutrition physiology research of insect is also mostly to be to carry out from the angle that affects that plant is caused that takes food of insect, fast development along with aquaculture, the fish feed trophic analysis shows, if with insect as fish feed, in the insect bodies contained trophic structure rationally, contain higher protein, chitin (shitosan) and aliphatic acid three classes, contain in addition vitamin, mineral composition and trace element; The protein content of a lot of insect stem bodys is up to more than 50%, it not only contains rich in protein and amino acid, also contain some and have the sp act material that some can regulate body physiological function, existing rainbow trout feed adopts the compositions such as fish meal, soya-bean cake, Mussel Powder, mineral mixture, lysine, wheat bran on the market.Although this feed can provide nutriment, the content of its crude protein about about 35～18%, can not fully satisfy fish to the crude protein needs greatly; And function singleness, there is not its special function rainbow trout aspect preventing and curing diseases.

Caste is more, and biomass is huge, has efficient growth and breeding ability and indomitable vitality, and propagation generation is short, index of reproduction is high, feeding cost is cheap, the organic transformation rate high.Insect feedstuff can improve the utilization rate of nutrient, alleviates the problem of manure contamination environment, progressively enlarges the production of China's protein feed, and the exploitation of worm source feed and feed addictive and development will have wide DEVELOPMENT PROSPECT undoubtedly.

Summary of the invention

The present invention overcomes the deficiencies in the prior art, proposes a kind of worm source property rainbow trout feed and preparation method thereof, can promote the growth of rainbow trout, can control the incidence of disease again, improves survival rate.

A kind of worm of the present invention source property rainbow trout feed and preparation method thereof is characterized in that: be comprised of the insects stock and adjunct; Wherein insects is comprised of bread worm 15～20%, white ant 15～20%, fly maggot 15～20%, silkworm chrysalis 15～20%; Auxiliary material is comprised of egg 15～20%, broom corn millet 3～6.5%, algae powder 2～5%, soybean oil 4～8%, ternip 2～3%, radish seed 2～8%, garlic 2～8%, and described percentage is weight percentage.

A kind of worm of the present invention source property rainbow trout feed and preparation method thereof, its concrete technical scheme is:

A. take by weighing insects raw material bread worm, white ant, fly maggot, silkworm chrysalis according to above-mentioned mass percent, sieve goes extremely, stiff and bad pupa and other fiber impurity, pulverizes, and through fine grinding, screening, gets 80～120 purpose small proteins, and is stand-by;

B. take by weighing auxiliary material according to above-mentioned mass percent; Broom corn millet, algae powder, radish seed were pulverized 80～120 mesh sieves, with ternip, air-dry 80～120 mesh sieves of pulverizing of garlic, it is put into mixer with the described small protein of a step and 4～8% soybean oils mix 4～8min, it is mixed;

C. the raw material after mixing adds complete egg to be pulverized again, makes all components can both pass through 90 mesh sieves, and the material after the pulverizing passes into 85 ℃ the modified 5～10min of steam, then makes raw material 90 ℃ of lower granulations, and granular size is 1～3mm;

D. under 95 ℃ of conditions, feed granules is placed drying machine drying, with the oven dry after pellet be cooled to normal temperature after, obtain described a kind of rainbow trout feed take insect as raw material.

A kind of worm of the present invention source property rainbow trout feed and preparation method thereof, its indication ternip, garlic will carry out air-dry rear pulverizing, and water content is lower than 5%; Its indication egg is complete raw egg, with its with blend after feed mixes, and stir.

A kind of worm of the present invention source property rainbow trout feed, its crude protein content are 51～65, crude fat content is 11～20, carbohydrate 12.4～22.0, ash content 9.5～14.5, and unit is 1,000,000 joules/kilogram.

A kind of worm of the present invention source property rainbow trout feed and preparation method thereof, its beneficial effect is: animal protein and content of fatty acid are high, and mineral element is abundant, and contains abundant V _A, V _B1, V _B2, V _DAnd ergosterol; Add in addition broom corn millet, algae powder, ternip, radish seed, garlic so that also contain beta carotene, V in the nutritional labeling _E, V _B6With mineral matter elements such as the calcium, magnesium, phosphorus and the iron that enrich, zinc, copper, comprehensive nutrition promotes growth, the strong digestibility of attractant is high, strengthen intestinal immunity and prevent that virus disease from occuring, the feed water stability is good, is difficult for polluting breeding water body water quality, and free from extraneous odour, without organic residue, safety in utilization is better, and more wide application prospect is arranged.

The specific embodiment

A kind of worm of the present invention source property rainbow trout feed and preparation method thereof is achieved as follows:
