Description

Soft feed of a kind of minimizing dermopathic pine needle of fish and preparation method thereof

Technical field

The present invention relates to technical field of aquaculture, be specifically related to soft feed of a kind of minimizing dermopathic pine needle of fish and preparation method thereof.

Background technology

Pine needle, bitter, warm in nature, have extra-nutrition, invigorating the spleen is regulated the flow of vital energy, and dispels pathogenic wind and remove dampness, the effects such as killing parasites to relieve itshing.Modern study shows, containing several amino acids, macro-and trace-element, vitamin, bacteriocidin in pine needle, especially carotene carotene content is higher.Abroad, utilize the existing history for many years of pine needle feeding animals, and production realizes industrialization.But technique is started late at home, China's overwhelming majority pine needle raw material is processed as fuel wood or waste material, has not only wasted resource but also created to various damage by forest-insects to perch breeding place, also easily causes forest fire.China's pine tree kind is more, there are Korean pine, larch, masson pine, kahikatea, black pine etc., it is estimated, there is coniferous forest area about 0.7 hundred million hectares in China, can produce pine needle 3.0 tons by per hectare, whole nation coniferous forest produces pine needle per year just can reach 2.1 hundred million tons, if China makes good use of these pine needle resources rationally and effectively, the consumption of the additives such as cereal feed grain and vitamin can not only be saved in a large number, also can improve the quality of animal product, reduce feed cost, increase the economic benefit of feed, raising.Because present stage China technology in the processing and utilization of pine needle is ripe not enough, domestic-developed fish out pine needle feed also also exists the shortcomings such as palatability difference, food calling is weak, growth is slow, the culture-cycle is long, in order to realize the Appropriate application of China's pine needle resource, in order to realize the lifting of aquatic fish culture benefit, be necessary in depth to research and develop pine needle.

Summary of the invention

In order to solve the deficiencies in the prior art, the invention provides soft feed of a kind of minimizing dermopathic pine needle of fish and preparation method thereof.

Technical scheme of the present invention is as follows:

The soft feed of a kind of minimizing dermopathic pine needle of fish, the weight portion of its constitutive material is: fresh pine needle 50-70, soybean residue 14-17, corn flour 9-11, grassleaf sweetflag leaf 0.4-0.6, aspergillus glaucus liquid 0.3-0.5, shrubby sophora extract 0.2-0.3, molasses 3-5, candida utili bacterium liquid 0.5-0.8, fermented soya bean 0.3-0.5, oil of ginger 0.1-0.2, edible gelatin 0.3-0.5.

The preparation method of the described soft feed of the dermopathic pine needle of minimizing fish, comprises the following steps:

(1) the fresh pine needle gathering pine tree felling or stay after pruning, reject the impurity such as pine-cones, wooden branch, retain spray and tender leaf, pine needle use water is eluriated 2-3 time, be placed on screen cloth and drain away the water, be laid in moisture bamboo mat dried on blade face again, be ground into 40-60 object pine needle powder with pulverizer, stand-by;

(2) the pine needle powder of step (1) is mixed rear steam with soybean residue, corn flour, grassleaf sweetflag leaf and steam 2-5 minute, take out, be cooled to room temperature, add water and regulate water content to be about 40-50%, again the activation aspergillus glaucus liquid of 3-5 days is inoculated into the inside, stirs, sealing, room temperature bottom fermentation 8-10 days, stand-by;

(3) after step (2) fermentation ends, in fermentation material, add shrubby sophora extract, molasses mix, and the activation candida utili bacterium liquid of 1-2 days is inoculated into the inside and again mixes, sealing, continue fermentation 3-5 days, stand-by;

(4) taking-up of the fermentation material of step (3) mixed with fermented soya bean, oil of ginger and remaining raw material, pass into steam and steam 2-3 minute, cooling, regulate water content to be about 28-38%, make the soft pellet diet of particle diameter 2.5-10 millimeter, pack seals, Cord blood.

Beneficial effect of the present invention:

The present invention adopts step fermentation, first by pine needle powder and soybean residue, corn flour, grassleaf sweetflag leaf matches, by inoculation Aspergillus glaucus to large molecular fiber, fat and albumen are degraded, eliminate the bitter taste of pine needle, enhance the immunity function of fish, decrease infection and the invasion of pathogen, again with shrubby sophora extract, molasses coordinate, and again fermented by inoculation candida utili, improve the crude protein content of pine needle fermented product, and enhance fish to dermatophyte, but protozoon kill ability, finally by with fermented soya bean, oil of ginger coordinates, enhance the food calling effect to fish and antibacterial action.Feed matter of the present invention is soft, palatability is good, there is strong aromatic odor, the immunity function of fish can be strengthened, strengthen fish to the resistivity of bacterium, fungi, protozoon, reduce the generation of the disease such as saprolegniasis, white skin disease, red skin disease, fin rot, scales upright of fish, improve survival rate and the income of fish culture.

Detailed description of the invention

Below in conjunction with the embodiment of the present invention, be clearly and completely described the technical scheme in the present invention, every simple distortion that other are made when not departing from core of the present invention or amendment all fall into protection scope of the present invention.

The soft feed of a kind of minimizing dermopathic pine needle of fish, the weight portion (kilogram) of its constitutive material is: fresh pine needle 50, soybean residue 14, corn flour 9, grassleaf sweetflag leaf 0.4, aspergillus glaucus liquid 0.3, shrubby sophora extract 0.2, molasses 3, candida utili bacterium liquid 0.5, fermented soya bean 0.3, oil of ginger 0.1, edible gelatin 0.3.

The preparation method of the described soft feed of the dermopathic pine needle of minimizing fish, comprises the following steps:
