CN104509733A - Mixed feed for young eel and preparation method thereof - Google Patents

Abstract

The invention relates to a mixed feed for young 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: 5-9 parts of a mixed white fish meal, 23-27 parts of alpha-starch, 63-67 parts of a high quality protein, 0.4-0.5 part of vitamin complex, 0.4-0.5 part of composite minerals, 0.4-0.5 part of calcium dihydrogen phosphate, 0.4-0.5 part of choline chloride and 0.4-0.6 part of amino acid. The preparation method is as below: evenly mixing the mixed white fish meal, alpha-starch and high quality protein, 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 young 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 elver mixed feed and preparation method thereof

Technical field

The present invention relates to a kind of preparation method of elver feed, specifically a kind of elver 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.

For the yeast of beer brewing.Mostly be the different cultivars of saccharomyces cerevisiae (Sac-charomyces cerevisiae).E.C.Hansen(1883) start to be separated culture yeasts and it is used for beer brewing.The bottom yeast that Denmark Carlsberg brewages research institute is famous.Cellular morphology is identical with other culture yeasts, is subglobose ellipsoid, different from wild yeasts.Brewer's yeast is typical top fermenting yeast conventional in Beer Brewage.Thalline vitamin, protein content are high, can eat, medicinal and fodder yeast, can also from wherein extracting cromoci, nucleic acid, glutathione, thromboplastinum, coacetylase and atriphos etc.In the microbioassay of vitamin, conventional brewer's yeast measures biotin, pantothenic acid, thiamine, pyridoxol and inositol etc.

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

Summary of the invention

The object of this invention is to provide a kind of elver mixed feed and preparation method thereof, this feed contains mixing white fish meal provides sufficient nutrient protein, be applicable to the nutritional need that elver sashimi (raw fish) is long, 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.
