Abstract

The invention discloses a feed special for breeding young eels and a preparation method thereof. The feed is made of the following raw materials in parts by weight: 180-200 parts of potato dregs, 80-120 parts of fresh snail meat, 20-25 parts of corn oil, 30-50 parts of bean residues, 100-120 parts of rice bran, 2-3 parts of scallop powder, 8-10 parts of fresh earthworms, 1-2 parts of sodium alginate, 3-5 parts of carboxymethyl cellulose, 5-8 parts of adsorbent and a proper amount of water. In particular, an edible feed for young eels consists of vegetarian proteins and meat proteins, so that the nutrient balance of the young eels can be adjusted reasonably. Meanwhile, the vegetarian proteins are added properly, so that the activity of in-vivo elated enzymes in young eels is prompted. Moreover, the feed is proven to be more beneficial to the health of eels, and tastes better.

Description

A kind of young eel cultivation special feed and preparation method thereof

Technical field

The invention belongs to the technology field of feed, be specifically related to a kind of young eel cultivation special feed and preparation method thereof.

Background technology

Swamp eel is commonly called as yellow eel " Changyu " sieve eel " field eel " and, without squama princess etc., belongs to net-rope Actinopterygii, Symbranchir, He Sai section, Monopterus.In snakelike, body is without squama, without paired fin, median fin degenerates and only leaves unconspicuous skin pleat, dwell at the bottom of fresh water for warm band life fish, often inhabit river course " lake " irrigation canals and ditches " in small reservoir and rice field, live in caves, in the daytime hide in cave, go out cave night to look for food, carnivorous, children's eel is mainly ingested earthworm " wheel animalcule " cladocera, eel is become mainly to ingest husky freshwater mussel " earthworm " small fish " assorted shrimp etc., sometimes to hold concurrently the little duckweed of the food " plant such as filamentous algae, also to ingest under propagating condition artificially mixed feed, small-sized net cage supports the popularization of eel pattern, accelerate the development of swamp eel healthy aquaculture, in the urgent need to its safe and efficient environmentally friendly mixed feed of industrialization development.

Swamp eel has higher nutrition and medical value, at home and abroad supply falls short of demand in market, it is important export-oriented commodity, due to artificial a large amount of seizure, in addition a large amount of uses of farmland Pesticides chemical fertilizer, making China's swamp eel wild resource drop to every mu of annual production less than 0.5 kilogram by every mu of annual output 6 kilograms of the sixties, is one of China's important famous-particular-excellent aquatic products wideling popularize cultivation at present, more than 300,000 tons (2012 annual data), the output value is more than 18,000,000,000 yuan for the culture of swamp eel annual production of current China.

Summary of the invention

For solving ricefield el fodder overlong time in water, easily decompose waste, the problem of nutrition leak etc., the present invention invents a kind of young eel cultivation special feed, and for the raising of young eel, while saving feed use amount, improve the utilization rate of feed, concrete grammar is as follows:

A kind of young eel cultivation special feed, it is characterized in that, be made up of the raw material of following weight portion: soil dynamic test 180 ~ 200, fresh screw meat 80 ~ 120, corn oil 20 ~ 25, soybean residue 30 ~ 50, rice bran 100 ~ 120, dried scallop powder 2 ~ 3, fresh earthworm 8 ~ 10, sodium alginate 1 ~ 2, carboxymethyl cellulose 3 ~ 5, adsorbent 5 ~ 8 and appropriate water;

Described adsorbent is by weight ratio by fresh livestock edible forage stalk 50 ~ 60 parts, added 5 ~ 10 parts, particulate quartz sand and 10 ~ 15 parts, the water of 20 ~ 40 mesh sieves, 30 ~ 40min is to homogenate shape in grinding, then centrifugal stalk sediment fraction, precipitation is soaked in water after washing 2 ~ 3 times and puts into 10wt% sodium bicarbonate solution, soak 20 ~ 30h, centrifugal after completing, gained precipitation is dried to obtain pulvis, last by weight proportion by aforementioned gained pulvis: land plaster: soybean oil: white wine: water=20: after the ratio mixing of 4: 2: 3: 50, to obtain after stirring.

A preparation method for young eel cultivation special feed, is characterized in that, comprise following step:

(1) fresh screw meat is mixed with the water of 2 ~ 3 times of its weight portions, in grinding machine for grinding 40 ~ 50min to homogenate shape;

(2) rice bran is added the thickener that appropriate water is deployed into water content 40 ~ 50%, add the cellulase of its total weight parts 0.01 ~ 0.06%, after stirring and evenly mixing under 25 ~ 32 DEG C of temperature conditions ferment treatment 3 ~ 4h, then mix with the homogenate described in corn oil, soil dynamic test, soybean residue, carboxymethyl cellulose, (1) and other following residual components do not related to, make feedstuff main material;

(3) be added to by adsorbent in fresh earthworm, become homogenate after being watered rear fine gtinding 30 ~ 40min in right amount, add dried scallop powder after stirring, then limit heating edge adds sodium alginate, dissolves completely to sodium alginate, is incubated 80 ~ 90 DEG C and becomes coated fertilizer;

(4) granulation after the feedstuff main material water content 40% of adjustment described in (2), size crosses 100 ~ 150 mesh sieves, and then in coating machine, the coated fertilizer described in preheating (3), is sprayed to the feed granules surface of rolling, cools under normal temperature with the form of spraying.

Innovative point of the present invention:

Be different from the preparation characteristic of common invention feed, the present invention is by the fresh green of livestock edible, rich fibrous forage is added in the coated fertilizer of ricefield el fodder with the form of powder, it filters after forage defibrination, then clean, remove most mesophyll part, residual fiber fragment is soaked with weakly alkaline solution sodium acid carbonate again, improve its surface tension and hydrophily, finally dry to obtain pulvis, with a certain amount of land plaster, the allotment that adds water after soybean oil and white spirit mixed is made, string has absorption to amino acid, protection and anti-oxidation effect, and environmental protection, intestines peristalsis can be excited to promote digestion simultaneously, white wine slightly can improve smell dispersion effect and eliminate the effect of amino acid polarity, soybean oil can improve feed coating agent hydrophobic property.

Mix being used for the highly seasoned bait that smell disperses with the adsorbent of modulation during use, then long fine gtinding, last make coating agent with being added in main carrier, protein-based meat mostly is for bait, the main body of its odor dispersion is amino acid, the peptide bond between protein is destroyed by fine gtinding, be conducive to amino acid free out, smell is denser, then utilize there is adsorbing adsorbent, smell can retain for a long time, and absorption after amino acid more stable, smell is not perishable, permanently effective.

Beneficial effect of the present invention: the present invention is a kind of edible feed of swamp eel cub, it is made up of vegetable protein matter part and carnivorous protein two parts, the nutrient balance of Reasonable adjustment swamp eel cub, simultaneously suitably add vegetarian diet proteinoid composition, the activity of relevant enzyme in body when being conducive to promoting that swamp eel is immature, and confirm the health being more conducive to swamp eel, taste is also better, this is the feed in a kind of long-time preservation water simultaneously, avoid flow action, affect graininess and the globality of feed, easily cause the problems such as nutrition leak, thin film is plated at feed surface with sodium alginate, be conducive to shaping, add earthworm and add the deliciousness that dried scallop powder promotes smell, so the sealing process to smell need not be worried, the feed of cub is lured in the effect serving as attractant on the contrary.
