Description

A kind of black young eel mixed feed and preparation method thereof

Technical field

The present invention relates to a kind of preparation method of black young eel feed, specifically a kind of black young eel mixed feed and preparation method thereof, belongs to eel feed preparing technical field.

Background technology

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.

Feed stripped is used for the feed of the animal such as pig, chicken, and these feeds need containing high-quality protein, the pig in especially young age and chicken.Because young animal is in growth animated period, to the demand of protein and require Amino Acids in Proteins large percentage, fish meal as animal protein, amino acid ratio wherein and the amino acid needed for animal closest.

The feed of aquatic livestock is used for aquatic livestock as the primary raw material of the feed proteins such as fish, crab, shrimp.Fish meal and the amino acid ratio needed for aquatic livestock closest, add fish meal can ensure that aquatic animal to grow is very fast.

The feed of fur-bearing animal is used for some fur-bearing animals as the feed of fox, racoon dog etc., and fur-bearing animal is carnivorous mostly, and comparatively large to the demand of protein in growth, high-quality fish meal is the first-selection of these animal feed raw materials as protein raw material.

Gluten is also known as active face strength flour, wheat gluten protein, it is the native protein extracted from wheat (flour), in faint yellow, protein content is up to 75% ~ 85%, that to have viscosity, elasticity, extensibility, film forming and liposuction Gluten be a kind of excellent flour-dough improver to nutritious plant protein resource, be widely used in the production of bread, noodles, instant noodles, also can with meat product in as water-loss reducer, be also simultaneously the basic material of high-grade aquatic feeds.It is domestic at present and using Gluten as the efficient green flour gluten fortifier of one, use it for the production of high-strength flour, tailored flour for bread, the unrestricted Gluten of addition still increases the effective ways of vegetable protein content in food.

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 black young eel.Therefore, the preparation method's tool developing a kind of black young eel feed is of great significance.

Summary of the invention

The object of this invention is to provide a kind of black young eel mixed feed and preparation method thereof, this feed contains mixing white fish meal provides sufficient nutrient protein, is applicable to the nutritional need of black young eel growth, promotes that it grows fast, meet the nutritional need that it is grown up, improve survival rate.
