Abstract

The invention belongs to the field of feed and is particularly suitable for feeding crabs. The crab feed is mainly characterized in that: (1) various animal and vegetable proteins, starch, trace elements, an auxiliary agent, a feeding promotion agent and the like serving as raw materials are compounded, so that the nutrient contents of the crab feed are more balance and comprehensive, and the requirements of the crabs during different growing periods can be met only by adjusting the ration of relative raw materials in the formula; and (2) the modified plastic processing machinery and process are used, and simultaneously the processes of mixing, shearing, curing, swelling, granulating and the like of the raw materials are also completed. Under the joint action of the two factors, the shapeof the product is stable, the flexibility is adjustable, and the product is not loosened after being soaked in water for several hours, so that the product is in accordance with the feeding habit of the crabs. Because the raw materials comprise fly maggots and earthworms that provide a certain amount of natural antibiotic and immunological factor, the product is insusceptible to decay and deterioration and can improve the disease-resisting capability of the crabs taking the crab feed. The crabs cultivated by the crab feed have the advantages of quick growth, fresh and smooth meat and rich nutrition.

Description

A kind of crab feed

Affiliated technical field:

Patent of the present invention belongs to the feed category.

Background technology:

Crab is a kind of delicious flavour and the food that is absorbed by the body easily, likes for people deeply.The foodstuff of crab is very assorted, and various animal and plants as long as it can chew movingly and all eat, thereby influence the fresh and tender and taste of its meat.In general, to improving the crab quality great effect is arranged in the suitable ratio that increases animal fodder of crab maturity period.At present the animal fodder of a lot of crabs is to be primary raw material with fresh or freezing small fish and fish meal, shortcomings such as the existence destruction stock of fish and easy polluted source and nutritional labeling are unbalanced, these feeds become pasty state easily in water, do not meet crab and like the eating habit of moulding soft diet, in addition, these feeds are putrid and deteriorated easily, polluted the water source and influenced the crab normal growth again, and this patent is special development for the shortcoming that overcomes above-mentioned all feeds.

Summary of the invention:

The main feature of this patent has two: (1) adopts animality and vegetable protein, starch based, trace element, auxiliary agent and the phagostimulant etc. of different types to carry out composite for raw material, thereby nutritional labeling is comprehensively balanced more, as long as adjust the demand that the ratio of relevant raw material in the prescription just can satisfy the crab different growing stages.(2) adopt the plastic processing machinery and the technology of repacking, finished technologies such as raw-material mixing, shearing, slaking, expanded, granulation simultaneously.Under the acting in conjunction of above-mentioned two factors, the profile of product is more stable, and pliability can be adjusted, and product can soak several hours in water and not loose, and the feed that meets crab is accustomed to.Product is not easy putrid and deteriorated, contain Fly maggot and earthworm in this and the raw material, thereby it is relevant with immune factor to contain a certain amount of natural antibiotics, has improved the resistance against diseases of crab after the crab feed simultaneously.The crab growth of cultivating with this patent product is rapid, and delicious meat is smooth, and is nutritious.Following examples are all by weight calculating.

Embodiment one:

Compound protein 30-95 part

Potato or Ipomoea batatas, or corn or chaff,

Or their mixture 30-90 part

Compound trace and moderate-element 0.01-5 part

Edible oil 0-10 part

Cobastab, or C, or their mixture 0-1 part

Asafoetide 0-2 part

Water 0-40.

Animal protein that compound protein refers in the prescription and phytoprotein two big classes, animal protein refers to fish meal, Fly maggot, earthworm.Vegetable protein refers to dregs of beans.With animal protein and vegetable protein compound be one of the feature of this feed.Proportioning is as follows:

Fish meal 50-80 part

Dregs of beans 0-35 part

Fly maggot 0-35 part

Earthworm 0-35 part.

The usage ratio of dregs of beans and Fly maggot and earthworm is adjusted at any time by the situation of growing and the market supply and demand situation of crab.The following weight ratio of general employing:

50 parts of fish meal

15 parts of dregs of beans

5 parts of Fly maggots

5 parts of earthworms.

Compound trace and moderate-element refer to sodium, sulphur, calcium, magnesium, iron, manganese, copper, zinc, boron, molybdenum.Its weight ratio is as follows:

Potassium 0-100 part

Sodium 100-200 part

Calcium 200-400 part

Magnesium 0-50 part

Iron 0-20 part

Manganese 0-5 part

Copper 0-3 part

Zinc 0-10 part

Selenium 0-1 part.

The general following weight ratio that adopts:

Sodium 100

150 parts of calcium

50 parts in magnesium

8 parts of iron

1 part in manganese

1 part of copper

3 parts on zinc.

The compound that contains above-mentioned element is pulverized respectively, evenly mixed after the weighing, get final product in the adding of the ratio in the feed formula.

Embodiment 2: as a kind of crab feed of saying among the embodiment one.The raw material weight of children's crab feed is such as following:

40 parts of compound proteins

Potato, or Ipomoea batatas, or corn, or chaff, or 60 parts in their mixture

0.5 part of compound trace and moderate-element

1 part of edible oil

Cobastab, or C, or 0.2 part in their mixture

0.1 part of asafoetide

Water 10-15 part.

Embodiment 3: as a kind of crab feed of saying among the embodiment one.Growth period crab feed raw material weight such as down:

65 parts of compound proteins

Potato, or Ipomoea batatas, or corn, or chaff, or 35 parts in their mixture

0.5 part of compound trace and moderate-element

1 part of edible oil

Cobastab, or C, or 0.2 part in their mixture

0.1 part of asafoetide

Water 10-15 part.

Embodiment 4: a kind of crab feed, it is characterized in that adopting single screw rod that plastics industry blend granulation commonly used uses or double screw extruder through converting, as long as the raw material that tentatively mix are added in the charging bucket of extruder, just can finish technologies such as shearing, fragmentation, blend, plasticizing, slaking, expanded, granulation simultaneously, make the product that meets this patent requirement.
