Abstract

The invention discloses feed for improving immunity of American reeves shads and a preparation method for the feed. The feed comprises 25-30 percent of fish meal, 3-7 percent of squid powder, 3-7 percent of gluten and enzyme powder, 3-7 percent of corn protein powder, 1-3 percent of skimmed malt, 15-20 percent of wheat middling, 2-5 percent of refined fish oil, 8-12 percent of soya bean meal, 8-12 percent of peanut meal, 0.1-0.5 percent of choline chloride at the mass concentration of 50 percent, 0.8-1.5 percent of monocalcium phosphate, 0.1-0.3 percent of multi-vitamin for fish, 1.5-2.5 percent of powder coating of astragalus extract, 1-5 percent of gunk for fish, 1-3 percent of bran, and 1-2 percent of zeolite powder. The feed is simple in preparation and balanced and abundant in nutrition, and can meet the production demand of the American reeves shads, improve the immunity and disease resistance of fish body, and reduce water body pollution caused by feeding feed in fish farming process, palatability of the feed can be improved, and the survival rate of the American reeves shads is enhanced.

Description

A kind of feed for improving U.S.'s hilsa herring immunity and preparation method thereof

Technical field

The present invention relates to a kind of feed, is a kind of feed for improving U.S.'s hilsa herring immunity and preparation method thereof specifically, belongs to aquatic product matched field of fodder.

Background technology

U.S. hilsa herring (American shad, Alosa sapidissima) belonging to Clupeiformes, clupeidae is individual maximum, the fastest a kind of hilsa herring of the speed of growth in the world.Its natural population mainly is distributed in the Eastern North America coastal waters, and 18-32 ℃ of growth thermophilics can be lived in fresh water or brackish water, are wide temperature migration fishes.It is thick that this oppresses thin fat, and delicious flavour is nutritious, is the improved seeds of intensive culture.With the Changjiang river hilsa herring, the Fuchunjiang River hilsa herring of China be equal different geographic populations, and its NATURAL DISTRIBUTION waters and latitude, meat flavour and profile are also basically identical.In the situation that introducing Chinese substitute as the Changjiang river hilsa herring in 2003, the endangered U.S. of the Changjiang river hilsa herring hilsa herring enters China market.

Since two thousand three, China introduces nearly ten million embryonated egg from the U.S. every year, has formed the upsurge of cultivation U.S. hilsa herring.Although cultured area and quantity enlarge year by year, accident occurs again and again, and the culturing reeves shads success rate is very low, has brought irremediable economic loss to the raiser, has dampened cultivation enthusiasm.By analyzing the lesson of domestic raiser U.S. culturing reeves shads failure, we find, a lot of reasons be since in artificial high-density breeding situation water body easily pollute the hilsa herring immunity degradation and cause death.Therefore be necessary to provide a kind of feed that can improve hilsa herring immunity, thereby make U.S. hilsa herring propagate stable, healthy growth under the pattern artificially in high density.

Summary of the invention

Goal of the invention: under artificial high-density breeding, easily pollute the problem that causes immunity degradation dead because of water body in order to solve U.S. hilsa herring, the purpose of this invention is to provide a kind of feed for improving U.S.'s hilsa herring immunity and preparation method thereof, it is that the active ingredient in the traditional Chinese medicine Radix Astragali of clear efficacy is added in the hilsa herring feed after effectively extracting, thereby improves the method for its immunity and survival rate.

Technical scheme: in order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of feed for improving U.S.'s hilsa herring immunity, comprise following component, content is by weight percentage in feed for each component: fish meal 25 ~ 30%, cuttlefish powder 3 ~ 7%, paddy Ruan ferment powder 3 ~ 7%, corn protein powder 3 ~ 7%, degreasing Fructus Hordei Germinatus 1 ~ 3%, inferior powder 15 ~ 20%, refined fish oil 2 ~ 5%, dregs of beans 8 ~ 12%, peanut meal 8 ~ 12%, mass content is 50% Choline Chloride 0.1 ~ 0.5%, calcium dihydrogen phosphate 0.8 ~ 1.5%, fish multidimensional 0.1 ~ 0.3%, Radix Astragali extractive solution spray powder 1.5 ~ 2.5%, fish premix 1 ~ 5%, wheat bran 1 ~ 3%, zeolite powder 1 ~ 2%.

As preferred version, the content of above-mentioned each component of feed is respectively: fish meal 30%, cuttlefish powder 5%, paddy Ruan ferment powder 5%, corn protein powder 5%, degreasing Fructus Hordei Germinatus 1%, inferior powder 16%, refined fish oil 4%, dregs of beans 12%, peanut meal 12%, 50% Choline Chloride 0.3%, calcium dihydrogen phosphate 1.2%, fish multidimensional 0.25%, Radix Astragali extractive solution spray powder 2.25%, fish premix 3%, wheat bran 2%, zeolite powder 1%.Above component all has commercial product and all can purchase.

Among the present invention, fish meal provides protein and energy, and former for high-quality nitrogen, fish meal and cuttlefish reach 35% and not only satisfy the growth requirement but also controlled cost.

The content of wheaten starch is higher in the inferior powder, so certain viscosity is arranged, can play the effect of adhesive in feed.16% inferior powder is arranged in the fish meal, add good modified and granulation, just can satisfy fish meal to fusible requirement, needn't add in addition adhesive.Fish are very high to the starch digestibility in the inferior powder in addition, inferior powder or the good energy.

Fish oil mainly provides energy and plays the food calling effect.

Dregs of beans, peanut meal mainly provide proteinogen and energy.

The important effective active composition of the Radix Astragali is astragalus polyose (APS), and APS is by the integrally-regulated cellular immunity that promotes to animal spleen T lymphocyte Th1 type and Th2 cytokines mRNA expression.Thereby have research find Chinese herbal medicine astragalus can improve CD4+CD25+ FOXP3+ T cell ratio this point out it can promote CD4+ T cell to strengthen body immunity towards the ratio that the regulatory T Cell Differentiation improves regulatory T cell/responsiveness T cell.

The preparation method of above-mentioned feed for improving U.S.'s hilsa herring immunity; at first with fish meal; the cuttlefish powder; paddy Ruan ferment powder; corn protein powder; dregs of beans; peanut meal; inferior powder; fish oil; fish premix; calcium dihydrogen phosphate; 50% Choline Chloride; wheat bran; zeolite powder; mix according to the above ratio with the Radix Astragali extractive solution spray powder; mix by the micronizer pulverizing and be mixed material; mixed material is moved to modulator to be passed into steam to be modulated to temperature of charge is 63-80 ℃; moisture 12%-16%; enter the extrusion granulator after the modulation and make the expanded pellet diet particle; particle diameter is 2.5mm; feed granules after expanded is dried; cooling namely obtains described feed for improving U.S.'s hilsa herring immunity.

Beneficial effect: compared with prior art, advantage of the present invention is: prepare simple, balanced in nutrition abundant, can satisfy the Production requirement of U.S. hilsa herring, and can improve immunity and the resistance against diseases of fish body, reduce the water pollution that causes because of feedstuff feeding in the breeding process, improve the palatability of feed, improve the survival rate of U.S. hilsa herring.
