Description

A kind of black carp feed

Technical field

The present invention relates to a kind of feed, relate in particular to a kind of black carp feed.

Background technology

Black carp is one of China four large Chinese carps, is the delicacies that consumer likes always, especially on New Year's Day or other festivals, and first-class delicacies and the gift of wedding celebration happy event.At present, in the cultural technique of black carp, there are several large problems: first, in China's aquaculture, be mostly under the environment of the hydrostatic pool, high-density breeding causes the precipitations such as a large amount of aquatic livestock excretas, remaining bait, disinfectant water-bed, then be decomposed and discharge a large amount of harmful substances, make the increase of aquaculture water cultivation density, water body environment worsens, the farming disease harms also increasingly sharpens, and many diseases are serious threat culture benefit.And the primary pollution source that the loss of feed in water and excremental accumulation have become water body causes water quality deterioration, pathogen amount reproduction, survival rate declines, and dosage increases, and changes water frequent, and then causes aquaculture cost to rise.Therefore, the quality of feed and utilizability are one of critical limitation factors that can culture fishery sustainable development.

Summary of the invention

For addressing the above problem, the invention discloses a kind of black carp feed.

A kind of black carp feed, the percentage by weight of each component is: pig lung: 10%-20%, rapeseed dregs: 10-20%, dregs of beans: 10%-15%, rice bran: 8%-15%, grease: 2%-4%, fish meal: 15%-20%, sea-tangle: 6%-10%, salt: 0.1%-0.5%, wheat bran: 3%-15%, Choline Chloride: 0.1%-0.3%, premix: 0.7%-1.8%.

In described nutrition fish meal, the concrete weight proportion of each composition is: pig lung: 20%, and rapeseed dregs: 20%, dregs of beans: 15%, rice bran: 15%, grease: 3%, fish meal: 15%, sea-tangle: 7%, salt: 0.5%, wheat bran: 3%, Choline Chloride: 0.3%, premix: 1.2%.

Production technology:

1) just pulverize: raw material warehouse entry, tentatively pulverize, by proportioning, mixed;

2) separating twice: above raw material is further pulverized, mixed;

3) expanding treatment: the raw material of separating twice is carried out expanded, puffed degree reaches 1.8;

4) dry;

5) outer spraying;

6) cooling, packing.

Beneficial effect of the present invention is: of the present invention is a kind of black carp feed, adopt multiple animals and plants composition hybrid modulation to form, in mixture, contain rich in protein, fat, vitamin and mineral matter, be conducive to the absorption of the nutritional labeling of fish, be convenient to growing of fish, and each composition that this nutrition fish meal adopts is common product, and production cost is low.

The specific embodiment

A kind of black carp feed, the percentage by weight of each component is: pig lung: 10%-20%, rapeseed dregs: 10-20%, dregs of beans: 10%-15%, rice bran: 8%-15%, grease: 2%-4%, fish meal: 15%-20%, sea-tangle: 6%-10%, salt: 0.1%-0.5%, wheat bran: 3%-15%, Choline Chloride: 0.1%-0.3%, premix: 0.7%-1.8%.

In nutrition fish meal, the concrete weight proportion of each composition is: pig lung: 20%, and rapeseed dregs: 20%, dregs of beans: 15%, rice bran: 15%, grease: 3%, fish meal: 15%, sea-tangle: 7%, salt: 0.5%, wheat bran: 3%, Choline Chloride: 0.3%, premix: 1.2%.

Production technology:

1) just pulverize: raw material warehouse entry, tentatively pulverize, by proportioning, mixed;

2) separating twice: above raw material is further pulverized, mixed;

3) expanding treatment: the raw material of separating twice is carried out expanded, puffed degree reaches 1.8;

4) dry;

5) outer spraying;

6) cooling, packing.

The present invention adopts multiple animals and plants composition hybrid modulation to form, in mixture, contain rich in protein, fat, vitamin and mineral matter, be conducive to the absorption of the nutritional labeling of fish, be convenient to growing of fish, and each composition that this nutrition fish meal adopts is common product, and production cost is low.
