Abstract

The invention relates to a mixed feed for adult eel feed and a preparation method thereof, and belongs to the field of preparation of eel feed. The eel feed is prepared from the following components by weight: 8-12 parts of a mixed white fish meal, 23-27 parts of alpha-starch, 60-62 parts of a high quality protein, 0.4-0.6 part of vitamin complex, 0.4-0.6 part of composite minerals, 0.4-0.6 part of calcium dihydrogen phosphate, 0.4-0.6 part of composite amino acid and 0.2-0.4 part of choline chloride. The preparation method is as below: mixing and evenly stirring the mixed white fish meal, alpha-starch and high quality protein under the condition of 200-300 r / min, conducting machinery crushing, sieving through a screen of 80-100 mesh, and conducting secondary mixing on the powder and the remaining ingredients to obtain a finished product. The feed is supplemented with mixed white fish meal for providing sufficient protein nutrition, and meets the growth requirements of adult eel; and the potato starch provides the energy for growth of young eel, promotes rapid growth, meets the nutritional needs for growth, and improves the survival rate.

Description

A kind of one-tenth eel mixed feed and preparation method thereof

Technical field

The present invention relates to a kind of preparation method of adult eel feed, specifically a kind of one-tenth eel mixed feed and preparation method thereof, belongs to eel feed preparing technical field.

Background technology

Eel class the history of life Bao Kuo ︰ ovum and the young in the mode of swimming marine diffusion, metamorphosis, elver with become the growth of eel, adult to the migration of ocean breeding area.Typical young fish length and flat-sided, transparent, gluey.There is obvious W shape muscle segment and to the sharp-pointed tooth protracted.With diatom and little shell-fish for food.Various oceans fish are their harmful animals.The larval stage of torrid zone eel class may be 4 ~ 6 months.But that lives in temperate zone reaches more than 1 year.As suitable ocean current, the young is just from one-tenth eel breeding area to drifting everywhere.Metamorphosis is started very soon after growing up to.Health becomes cylindrical shape, and body weight about alleviates 90%; Anus position is advanced to close to middle; The tooth during young disappears; Kiss becomes circle; Dorsal fin starting point moves forward; The melanocyte of the young disappears.What have also loses pectoral fin or health shortening.Grow the serial deduction obtained according to the observation in aquarium with by continuous print in planktonic organism sample, some young character remains into abnormal Hou, thus contributes to identification kind.The number of this Bao Kuo ︰ muscle segment, the growth of dorsal fin, anal fin and tail fin fin ray, the relative position of Renal vascular and gall-bladder.Metamorphosis process also comprises the change of outstanding physiology, behavior, particularly takes the change that the life style in deep-sea, shallow sea or fresh water is relevant with adult.The elver that metamorphosis makes phylbosoma larva be transformed into can enter significantly different habitats.The metamorphosis of all eel classes may all complete at large midocean.The elver that eel Cobia belongs to enters fresh water once every year, and being March October to next year in Europe, is spring in other temperate regions.Eel class is growing in the ripe several years mainly carnivorous, eats the animal dwelt various zooplankter or the end.Ou Zhou eel Cobia about 10 years Hou maturations, but the extra large non-hibernating eggs class in the torrid zone may comparatively early.Grow and the carefully studying of maturation according to Ou Zhou eel Cobia, it is female, male all goes through several rank section ︰ neutral phase, precocity is feminized phase and young hermaphroditic phase, right Hou becomes raun or milter.Its sex is determined primarily of environmental factor.All eel classes all pass through distance migration near or far away to spawning ground when maturation.Spawning ground is generally arranged in continental slope or the not far sea basin of offshore.

Fish meal is raw material with one or more fish, the high-protein feed after processing of deoiling, dewater, pulverize.Global fish meal producing country mainly contains Peru, Chile, Japan, Denmark, the U.S., the former Soviet Union, Norway etc., and wherein Peru accounts for 70% of general trade amount with the export volume of Chile.China's fish meal output is not high, main grown place in Shandong Province, Zhejiang Province, be secondly the provinces and cities such as Hebei, Tianjin, Fujian, Guangxi.In latter stage in 20th century, the annual approximately import 700,000 tons of fish meal of China, about 80% from Peru, from Chilean import volume less than 10%, also has a small amount of import in addition from the U.S., Japan, country in Southeast Asia.Although fish meal is still that important animal protein adds feed so far, China feed worker is the low fish Meal Diet of research and probe and Diet without fish tankage always, and fermented bean dregs is substitute products best at present.

CN 200910138321.7 provides a kind of eel feed, it by: shellfish powder 30%-55%, corn protein powder 8%-15%, milk powder 2%-4%, chicken blood meal 7%-10%, duck blood meal 1%-4%, sorghum gluten powder powder 4%-7%, blue or green worm powder 10%-20%, mineral additive 1%-2%, vinasse 2%-5%, cod-liver oil 3%-7%, vitamin intermixture 1%-2% form, and described percentage is weight percentage.In proportion above-mentioned substance is poured into mixing in mixer to mix thoroughly, then add quantitative grease and water, throw something and feed after sieving with the mesh screen of 60 after stirring into glutinous bulk.But feed does not add fish meal, be difficult to the growth demand guaranteeing into eel.Therefore, the preparation method's tool developing a kind of adult eel feed is of great significance.

Summary of the invention

The object of this invention is to provide a kind of one-tenth eel mixed feed and preparation method thereof, this feed contains mixing white fish meal provides sufficient nutrient protein, be applicable to into the nutritional need of eel growth, farina provides the energy needed for elver growth, promote that it grows fast, meet the nutritional need that it is grown up, improve survival rate.
