CN103704464A - Parabramis pekinensis feed and preparation method thereof - Google Patents

Abstract

The invention relates to a parabramis pekinensis feed and a preparation method thereof. The feed is prepared from the following raw materials in parts by weight: 8-12 of dried earthworm powder, 30-45 of soybean cakes, 15-25 of wheat bran, 8-12 of corn flour, 2-4 of egg yolk, 8-10 of a biological bacterium fermented material, and 5-10 of earthworm cast. The feed provided by the invention can meet the needs of parabramis pekinensis growth for various nutrients, and the feed utilization rate is high. The biological bacterium fermented material can improve the body immunity of parabramis pekinensis, the resistance to various pathogenic microorganisms and the anti-stress ability, thus better promoting the functioning of the production performance. The parabramis pekinensis feed can significantly increase the weight gain rate of parabramis pekinensis, reduce the feed coefficient, has an obvious growth promoting effect, and is safe and free of toxic and side effect after long-term use.

Description

Bream feed and preparation method thereof

Technical field

The invention belongs to field of feed, relate in particular to bream feed.

Background technology

Bream (Parabramis pekinensis), belongs to Cypriniformes, Cyprinidae, bream chub mackerel subfamily, bream genus, is commonly called as Changchun bream, bream flower, limit fish, careless bream, is distributed widely in the rivers and lakes of each Main River Systems of China.Bream is herbivorous fishes, take pasture and water, diatom, filamentous algae etc. as food, also eats a small amount of planktonic organism and aquatic insect.Bream is because meat is soft, and fat is abundant, and delicious flavour and being loved by the people is one of main cultured freshwater fish of China.After existing bream feed is fed, bream growth is slow.

Summary of the invention

The object of this invention is to provide a kind of bream feed and preparation method thereof, the bream of feeding growth is fast.

Technical scheme of the present invention is as follows:

A bream feed, is characterized in that being made by the raw material of following weight portion: dry earthworm powder 8-12, soya-bean cake 30-45, wheat bran 15-25, corn flour 8-12, yolk 2-4, biological bacteria fermentation material 8-10, wormcast 5-10; Described biological bacteria fermentation material makes by the following method:

Crop material is pulverized, powder of straw is put in fermentation vat, add the water of powder of straw weight 70-80%, the viable yeast of the carbohydrase of 1-2%, 0.5-1%, the lactic acid of the sodium chloride of 1-2%, 0.5-1%, stir the photosynthetic bacteria agent of rear access 1-3%, at 15 ℃～35 ℃ temperature, cultivate 2 days, treat that the bed of material covers with white hypha and sends fragrance.

The preparation method of described bream feed, is characterized in that each raw material to mix, and is processed into particle, dries.

Feed of the present invention can meet the demand of bream growth to various nutriments, and efficiency of feed utilization is high; Biological bacteria fermentation material can improve bream immunity of organisms, to the resistance of various pathogenic microorganisms and anti-stress ability, promote better the performance of its production performance; Can significantly improve bream rate of body weight gain, reduce feed coefficient, there is obvious growth-promoting effect, use for a long time safe without toxic side effect.

The specific embodiment

A bream feed, by following weight portion (kilogram) raw material make: dry earthworm powder 8, soya-bean cake 30, wheat bran 15, corn flour 8, yolk 2, biological bacteria fermentation material 10, wormcast 10; Described biological bacteria fermentation material makes by the following method:

Crop material is pulverized, powder of straw is put in fermentation vat, add the water of powder of straw weight 70%, 2% carbohydrase, 1% viable yeast, 2% sodium chloride, 1% lactic acid, stir the photosynthetic bacteria agent of rear access 3%, at 15 ℃～35 ℃ temperature, cultivate 2 days, treat that the bed of material covers with white hypha and sends fragrance.

The preparation method of described bream feed, is characterized in that each raw material to mix, and is processed into particle, dries.

Feed applications of the present invention is carried out pool mouth culture experiment in the bream raiser of family.Fishpond stocking size is 15-20 tail/kg, and breeding density is 1500-1800 tail/mus, puts altogether 2 mu in a suitable place to breed, fish after feeding seven months.Bream average weight is 560.74g/ tail after measured, is in a good state of health, and body colour and epidermal mucus are normal, through dissecting liver pancreas, observe normally, the overall anti-stress ability of bream is strong, and without rubescent scared phenomenon, Long-term Feeding result shows this premix safe without toxic side effect.

Claims (2)
