Abstract
The invention discloses a high-immunity puffed biological feed for river crabs. The high-immunity puffed biological feed for river crabs is prepared from the following components in parts by mass: 10-25 parts of fish soluble, 5-15 parts of earthworm paste, 3-18 parts of bean pulp 43, 0-40 parts of rapeseed meal, 0-35 parts of cottonseed meal, 5-25 parts of flour, 15-35 parts of rice bran, 1-4 parts of fish oil, 3-5 parts of soybean oil, 1 parts of river crab premix, 0.1-0.2 part of kosteletzkya virginica tuber powder, 0.05-0.2 part of Spartina alterniflora extract. According to the high-immunity puffed biological feed for river crabs, the survival rate, the weight gain rate and the like of the river crabs can be remarkably increased due to the synergistic effect of Spartina alterniflora extract and other components and the color and luster of the river crabs are healthy and bright; and the immunity of the river crabs is improved remarkably due to the synergistic effect of Spartina alterniflora extract and kosteletzkya virginica.
Description
Technical field
The invention belongs to cultivation field, be specifically related to the expanded biological feedstuff of a kind of high immunity river crab.
Background technology
River crab also cries " crab " or " eriocheir sinensis ", Arthropoda Crustacea animal.The carapace that head and chest are combined into is square circular, and quality is hard.Front end body has a pair, and side has two to very hard sharp crab tooth.Crab a pair appendage is foremost the foot of a chela, and surface covers with fine hair; 4 pairs of steps are had after the foot of a chela, flat-sided and longer; Abdominal appendage is degenerated.The male and female of river crab can distinguish from its belly: female belly is rounded, and male belly is triangle.
River crab is the maximum fresh water crab of China's output, because to be of high nutritive value and delicious and dark in the having deep love for of consumers in general, become the aquaculture kind that the Yangtze river basin is important, but the defects such as existing feed for river crab exists, and cost is high, feed coefficient is large, river crab immunity is poor, survival rate is low, and the situation of Lou expecting easily is caused easily to cause the problems such as water pollutions due to the particularity of river crab feeding methods.
Summary of the invention
The defects such as the cost that in prior art, feed for river crab exists is high, feed coefficient large in order to overcome, unstable, river crab immunity is poor, the invention provides the expanded biological feedstuff of a kind of high immunity river crab.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
The expanded biological feedstuff of a kind of high immunity river crab, its raw material comprises following component: 10 ~ 25 parts, the molten slurry of fish, 5 ~ 15 parts, earthworm slurry, 43 dregs of beans 3 ~ 18 parts, the dish dregs of rice 0 ~ 40 part, cotton dregs 0 ~ 35 part, 5 ~ 25 parts, flour, 15 ~ 35 parts, rice bran, 1 ~ 4 part, fish oil, soybean oil 3 ~ 5 parts, river crab premix 1 part, 0.1 ~ 0.2 part, kostelezkya virginica block root powder, Spartina alterniflora's extract 0.05--0.2 part, described number is mass fraction.
The dregs of beans that above-mentioned 43 dregs of beans finger protein content are greater than 43%.The quality consumption of above-mentioned river crab premix is preferably 1% of the expanded biological feedstuff gross weight of high immunity river crab.
Above-mentioned feed is by making the cooperative effect between each component perform to maximization to the selection of raw material components and proportioning, achieve amino acid whose balance, and increased substantially digestibility by the molten slurry of fish, earthworm slurry with the cooperative effect of other component, improve the deposition efficiency of nitrogen, phosphorus etc., be greater than 35%; Feed coefficient drops to 1.1 from 2.5, formulation cost decline 500-700 yuan/ton; Accelerate the eating speed of river crab, in half an hour, can feed be completed, decrease the waste of feed, and slow down the pollution of water quality; By the cooperative effect between Spartina alterniflora's extract and kostelezkya virginica block root powder, the immunity of river crab is had and has further significantly promoted, survival rate can reach 98%.
Being prepared as of Spartina alterniflora's extract: harvesting Spartina alterniflora aerial part clean dry, concentrate through cyclic steam extracting, then dry, granulation at 40 ~ 50 DEG C, to obtain final product.
Above-mentioned prepared Spartina alterniflora's extract granularity uniformity is good.
In order to promote the cooperative effect between Spartina alterniflora's extract and other component further, in Spartina alterniflora's extract, general flavone content is not less than 9.00mg/g dry weight.
In order to reduce the cost of feed further, improve the eating speed of the digestibility of feed, conversion ratio and river crab simultaneously, preferably, the expanded biological feedstuff of high immunity river crab: its raw material comprises following component: 16 ~ 20 parts, the molten slurry of fish, 8 ~ 14 parts, earthworm slurry, 43 dregs of beans 3 ~ 18 parts, the dish dregs of rice 18 ~ 22 parts, cotton dregs 22 ~ 30 parts, 13 ~ 15 parts, flour, 20 ~ 25 parts, rice bran, 2 ~ 3 parts, fish oil, soybean oil 2 ~ 2.5 parts, river crab premix 1 part, 0.1 ~ 0.15 part, kostelezkya virginica block root powder, Spartina alterniflora's extract 0.1 part, described number is mass fraction.
In order to improve the conversion ratio of feed further, preferably, river crab premix is H01CF series 1% river crab premix.H01CF series 1% river crab premix can be bought from Zheng Chang feed technology Co., Ltd and obtain.
In order to accelerate further river crab eating speed, improve feed conversion rate, deduction and exemption water pollution, reduce costs, preferably, being prepared as of the molten slurry of fish: by chilled small fish, adult fish gruel is stirred with mixer, then be that under the aseptic condition of 25 ± 5 DEG C, natural enzymolysis 5-7 hour, to obtain final product in temperature; Being prepared as of earthworm slurry: will from numerous earthworm, washing impurity elimination, stirring into rotten shape with mixer, then add liquid of protease, is that under the aseptic condition of 30 ± 5 DEG C, enzymolysis 7-9 hour, to obtain final product in temperature.
The application all has no special requirements to chilled small fish with from numerous earthworm, existing all kinds.
The production method of feed is with reference to prior art.
The NM technology of the present invention is all with reference to prior art.
The expanded biological feedstuff of high immunity river crab of the present invention is by the cooperative effect of Spartina alterniflora's extract (BML) with other each component, make the aspects such as the survival rate of river crab, rate of body weight gain all have significant lifting, and make the color and luster of river crab more healthy, black bright; The cooperative effect of Spartina alterniflora's extract and kostelezkya virginica, has made immunity have and has promoted more significantly; The application to different protein sources and amino acid whose bioavailable efficiency, selects concrete raw material and Bi Lie to achieve amino acid whose balance according to river crab; And increased substantially digestibility by the molten slurry of fish, earthworm slurry with the cooperative effect of other component, improve the deposition efficiency of nitrogen, phosphorus etc., be greater than 35%; Feed coefficient drops to 1.1 from 2.5, formulation cost decline 500-700 yuan/ton, and survival rate can reach 98%; Accelerate the eating speed of river crab, in half an hour, can feed be completed, decrease the waste of feed, and slow down the pollution of water quality.
