Abstract

The invention relates to the field of aquatic animal feeds and especially relates to a puffed compound feed of micropterus salmonides and production method thereof. The feed is composed of following components, by mass, 50% of fish meal, 4% of beer yeast, 12.5% of high-gluten flour, 6% of wheat gluten, 18% of soybean meal, 3.5% of bean oil, 1.5% of phospholipid oil, 1.5% of monocalcium phosphate and 3% of a pre-mixed material. The invention provides the puffed compound feed of micropterus salmonides and the production method thereof. Nutritional indexes of the feed are described as follows: crude protein is not less than 48.0%, crude fat is not less than 9.0%, total phosphorus is not less than 1.3% and lysine is not less than 2.0%. Meanwhile, the feed is strong in phago-stimulation of micropterus salmonides, can float on water surface or sink very slowly, is good in stability when being soaked in water, is easy to soften, is high in digestion and absorption ratio and can reduce disease incidence.

Description

Micropterus salmonoides expanding compound feed and production method thereof

Technical field

The present invention relates to aquatic animal feed field, especially a kind of Micropterus salmonoides expanding compound feed and production method thereof.

Background technology

California perch claims again Micropterus salmoides, is a kind of fresh water predacious fish of disposition ferociousness, substantially by rivers and lakes grows wild, extremely rare and expensive because of its delicious meat, quantity, can only just can see in high-grade feast.Within nearly 2 or three years, start artificial feeding exploration, but be chilled fish entirely because fed bait is basic, cause the incidence of disease high, fishery resources waste greatly, for the restricted feeding manner of country, and existing feed raising California perch is very easily broken out liver pancreas pathology, growth retardation on the market.

Summary of the invention

The object of the invention is the deficiency in order to solve above-mentioned technology and a kind of Micropterus salmonoides expanding compound feed and production method thereof be provided, meet that California perch attractant is strong, the floating water surface of particle or very slowly sink, soak after water stability good, easily softening, high digestibility, reduce the incidence of disease.

In order to achieve the above object, the Micropterus salmonoides expanding compound feed that the present invention is designed, it is made up of fish meal 50%, brewer's yeast 4%, Strong flour 12.5%, tanimoto powder 6%, dregs of beans 18%, soya-bean oil 3.5%, phosphatide oil 1.5%, calcium dihydrogen phosphate 1.5%, premix 3%, and above-mentioned percentage is the mass percent that each component accounts for total amount.

A production method for Micropterus salmonoides expanding compound feed,

The first step: batching, exceedes ratio 5% bulk raw material: be stored in corresponding batch bin by sample through elevator by fish meal, brewer's yeast, Strong flour, tanimoto powder, dregs of beans, middle control arranges each raw material quantitative proportion;

Second step: raw material drops into mixer after burden balance automatic gauge, stirs 5-8 minute, ensures that the coefficient of variation is less than 7%;

The 3rd step: the raw material mixing leaves in treats crushing bin, carries out ultramicro grinding, ensures that fineness reaches 98% and crosses 80 mesh sieves;

The 4th step: the material after ultramicro grinding delivers into two mixed machines through conveying device, carries out secondary mixing after phosphatide oil, calcium dihydrogen phosphate and premix are added, and mixture homogeneity guarantees that the coefficient of variation is less than 7%;

The 5th step: carry out modified expanded, adjust charging rate, in add water and quantity of steam, cavity temperature reaches 120 degrees Celsius, slaking and sterilization; The pore size of template using is 1.0-5.0mm;

The 6th step: outer oil spout fat, by the liquid soya-bean oil of handling well, through flowmeter, by formula ratio setting, vaporific evenly outer spray, makes feed granules outward appearance reach color and luster even, the smooth full requirement of particle;

The 7th step: enter finished bin after cooling by high pressure positive blower adverse current, sieve and screen out nonstandard particle and powder;

The 8th step: be up to the standards, the packing of weighing, mark warehouse-in.

Micropterus salmonoides expanding compound feed and production method thereof that the present invention obtains, the nutritive index of the Micropterus salmonoides expanding compound feed of producing can reach crude protein >=48.0%, crude fat >=9.0%, total phosphorus >=1.3%, lysine >=2.0%; Have that the California of meeting perch attractant is strong simultaneously, the floating water surface of particle or very slowly sink, soak after water stability good, easily softening, high digestibility, reduce the advantages such as the incidence of disease.

Detailed description of the invention

The present invention is further described by the following embodiment.
