Abstract

The present invention discloses a black carp feed improving fish meat quality and a preparation method thereof. The feed consists of the following raw materials: fish flesh, snail powder, flour, bamboo shoot shells, bagasse powder, tenebrio molitor powder, pine needles, wheat germ, shrimp shell powder, citrus bigarradia leaves, rice bran oil, angelica keiskei, edible salt, allicin and probiotics. Compared with the prior art, the black carp feed has the following advantages: the feed is balanced in nutrition. By conducting fermentation of parts of the raw materials under the functions of filtrates of the pine needles and angelica keiskei, the feed can improve the esophagus and gastrointestinal functions, improve the disease resistance and avoid the addition of hormone drugs, is rich nutrition and high in utilization rate, has a food coefficient lower than 1.1 and a protein efficiency ratio higher than 1.9, and is obvious in economic benefits. The black carp is relative high in flesh quality, crude protein content and crude fat content.

Description

A kind of black carp feed improving flesh quality and preparation method thereof

Technical field

The invention belongs to technical field of aquaculture, be specifically related to a kind of black carp feed improving flesh quality and preparation method thereof.

Background technology

Mylopharyngodon piceus is the fish that a kind of color is blue or green, is distributed mainly on the plains region on the south China the Changjiang river, and North of Yangtze River is sparser；It is the main cultivation object in the important fishery resources in lower Yangtze and riverine lake and each lake, pond; one of " four large Chinese carps " for China's freshwater aquiculture; therefore China is big to the cultivation demand of Mylopharyngodon piceus; the major way wherein breeded fish during pond culture; in existing breeding process; in order to improve cultured output; substantial amounts of hormone medicine would generally be added; to accelerate weightening finish; resist the disease; but hormone medicine makes basic nutrition unbalanced sometimes, hinder the growth promoter of Mylopharyngodon piceus, reduce product quality.

Summary of the invention

It is an object of the invention to for existing problem, it is provided that a kind of black carp feed improving flesh quality and preparation method thereof.

The present invention is achieved by the following technical solutions: a kind of black carp feed improving flesh quality, it is made up of the raw material of following weight portion: the flesh of fish 18-25 part, snail powder 15-20 part, flour 20-25 part, bamboo shell 5-8 part, bagasse powder 10-12 part, Tenebrio molitor powder 4-6 part, Folium Pini 2-3 part, Fructus Tritici aestivi 2-4 part, shrimp shell meal 1-2 part, Petitgrain 0.3-0.6 part, Testa oryzae oil 0.4-0.5 part, angelica keiskei koidzumi 1-2 part, Sal 0.08-0.1 part, garlicin 0.01-0.02 part, microbial ecological agent 0.05-0.08 part.

As further improvement of these options, the crude protein content of described Tenebrio molitor powder, more than 68%, uses carbon dioxide supercritical fluid extraction technique to obtain.

Tenebrio molitor amyloid proteins content is high, nutritious, has giving off a strong fragrance, can improve the resistance against diseases of body in feedstuff, reduces blood fat.

As further improvement of these options, described microbial ecological agent is Bacillus licheniformis, and strain content is 10³-10⁸cfu/g。

The preparation method of a kind of black carp feed improving flesh quality, comprises the following steps:

(1) Petitgrain being dried powder process, then the flesh of fish is clean, stripping and slicing, is pulverized with 3-4mm fenestra electrical meat mincer, adds Petitgrain dry powder and garlicin in crushing process, and then sterilizing 20 minutes under conditions of 60-65 DEG C, then cool down standby；

(2) after Folium Pini and angelica keiskei koidzumi being pulverized, by water boiling and extraction 2 times, add for the first time and be equivalent to 3 times of water of its gross weight, decocting and extract 2 hours, second time addition is equivalent to 2 times of water of its gross weight, decocts and extracts 1.5 hours, twice filtrate is merged, obtaining mixing filtrate, will filter gained slag charge and dry, powder process is standby；

(3) bamboo shell is ground into the disintegrating slag less than 1cm, mixs homogeneously with bagasse powder, be subsequently adding above-mentioned gained filtrate, add mix homogeneously after microorganism formulation, ferment 2-3 days under conditions of 35-40 DEG C, dry, pulverize, obtain fermented product standby；

(4) unclassified stores in addition to Testa oryzae oil in surplus stock is mixed with lay-by material in above-mentioned steps (1), step (2), step (3), after stirring, under conditions of 90-100 DEG C, enter pelletize in extruding granulator；

(5) when above-mentioned pellet is cooled to 50-55 DEG C, by grease spraying system, Testa oryzae oil is sprayed on grain products, then cooled down by cooler, carry out packing.

Petitgrain dry powder and garlicin is added, it is possible to play the effect of the content of sterilization, improvement flesh of fish digestible protein and digestible fat, contribute to the raising of Mylopharyngodon piceus body constitution in the flesh of fish course of processing.

Folium Pini and angelica keiskei koidzumi coordinative role, have regulation immunity of organisms, improves the effect of esophagus and gastrointestinal function, and its extracting solution is used for ferment bamboo shell powder and bagasse powder, can improve its nutritional labeling utilization rate.

The present invention has the advantage that feed nutrition equilibrium in the present invention compared to existing technology, by part material is fermented under the effect of Folium Pini and angelica keiskei koidzumi filtrate, improve esophagus and gastrointestinal function, improve its resistance against diseases, avoid adding hormone medicine, feedstuff Middle nutrition enriches, and utilization rate is high, and feed coefficient is less than 1.1, protein efficiency ratio, PER is higher than 1.9, economic benefit is obvious, and Mylopharyngodon piceus flesh quality is higher, and crude protein content and crude fat content all increased.

Detailed description of the invention

Embodiment

A kind of black carp feed improving flesh quality, it is made up of the raw material of following weight portion: the flesh of fish 18-25 part, snail powder 15-20 part, flour 20-25 part, bamboo shell 5-8 part, bagasse powder 10-12 part, Tenebrio molitor powder 4-6 part, Folium Pini 2-3 part, Fructus Tritici aestivi 2-4 part, shrimp shell meal 1-2 part, Petitgrain 0.3-0.6 part, Testa oryzae oil 0.4-0.5 part, angelica keiskei koidzumi 1-2 part, Sal 0.08-0.1 part, garlicin 0.01-0.02 part, microbial ecological agent 0.05-0.08 part.
