Description

A kind of tilapia feed and preparation method thereof

Technical field

The present invention relates to feed, especially a kind of tilapia feed and preparation method thereof, belongs to technical field of aquaculture.

Background technology

Tilapia mossambica, has another name called fish, African crucian, non-crucian carp, Vietnam fish, Nan Yang crucian carp etc., and the meat flavour of Tilapia mossambica is delicious, fine and tender taste, and no matter be braised in soy sauce or steamed, taste is all good.After measured, containing 20.5 grams, protein in the every 100 grams of meat of Tilapia mossambica, 6.93 grams, fat, heat 148 kilocalories, calcium 70 milligrams, 50 milligrams, sodium, 37 milligrams, phosphorus, iron 1 milligram, vitamin B1 0.1 milligram, vitamin B2 0.12 milligram.Be the cultured fishes that the emphasis scientific research of World Water industry is cultivated, and be described as one of main source of following animal protein.

Along with the raising of people's living standard, the demand of people to aquatic products increases day by day, along with the development of culture fishery, the demand of feed is increasing, but current tilapia feed exists that cost is high, nutritional labeling not comprehensively, the defect such as nutrition is unbalanced, nondigestible, raw material sources are wideless.

Summary of the invention

The present invention is to solve existing feed Problems existing at present, provide a kind of have the advantage such as balanced in nutrition, easy to digest, cost is low, raw material sources are extensive tilapia feed.

For realizing above object, the technical solution used in the present invention is:

A kind of tilapia feed, this feed comprises the component of following portions by weight: peanut shell 20-40 part, corn flour 30-50 part, beancake powder 20-30 part, tapioca starch 20-30 part, rice bran 15-25 part, fish meal 10-20 part, peanut dregs of fat 8-15 part, mineral mixture 2-8 part.

Described mineral mixture comprises salt, calcium monohydrogen phosphate, bentonite.

The each composition weight number of described mineral mixture is than being salt 0.5-2 part, calcium monohydrogen phosphate 1-3 part, bentonite 0.5-3 part.

Described peanut shell contains the multiple nutritional components such as abundant fat, starch, cellulose, mineral matter, vitamin, but the utilization of people to peanut shell at present thinks little of, normal as fuel or discarded object, the raw material that peanut shell is used as feed can be turned waste into wealth, and the cost of feed can be reduced.

The described peanut dregs of fat are waste residues that peanut is left after oil expression, and current industrial a lot of people refines peanut oil with the dregs of fat, but the dregs of fat contain a large amount of carcinogens, and people is not suitable for eating.The peanut dregs of fat have very fragrant taste, are the food that fish is liked.

Described tilapia feed preparation method comprises the following steps:

(1) each raw material is taken by the ratio of weight and number of above-mentioned feed;

(2) dry after the raw material that step 1) takes being mixed, make its moisture be less than 10%, be crushed to 40-80 order, obtain mix powder;

(3) at high temperature granulated in granulator vapour system by mix powder, particle diameter is 2.5-4.0mm; Obtain feed granules;

(4) dried by feed granules under 100-120 DEG C of condition, be up to the standards packaging.

Further, described step (3) is granulated under the high temperature of 85-95 DEG C.

Described granulator is conventional granulator, buys in Jiangxi blue light mechanical & electronic equipment corporation, Ltd.

Compared with prior art, the beneficial effect that the present invention obtains is:

(1) the present invention uses peanut shell, tapioca starch, corn flour, cassava vinasse, the peanut dregs of fat etc. for raw material sources are extensive, cost is low, the cost of reduction feed that can be very large.

(2) comprehensive nutrition, balanced in nutrition, promotes that Tilapia mossambica grows up.

(3) absorption easy to digest, utilization rate is high.

(4) preparation technology of this feed is simple, and easy and simple to handle, preparation cost is low.
