Feed of a kind of feeding Takifugu obscurus and preparation method thereof
Technical field:
The invention belongs to technical field of animal, be specifically related to a kind of feed that is used for feeding Takifugu obscurus and preparation method thereof.
Background technology:
Fugu obscurus (Takifugu obscurus); The popular name globe fish is a kind of potential economic fingerling, and delicious, the edible rate of its meat flavour is high, nutritious; And liver and ovary can extract fugutoxin; Be used to treat neuralgia, spasm, bed-wetting etc., have high edible and medical value, therefore the value of exploitation arranged.
Fugu obscurus output is big, in the fishery of whole the Changjiang river, occupies certain weight proportion, has certain economic and is worth.But owing to excessively capture influence of various factors such as parent population and water pollution, fugu obscurus resource trend is exhausted in the Changjiang river, and therefore, propagating fugu obscurus artificially has been inevitable choice, and feed is the key of propagating artificially.
Because traditional fugu obscurus does not have ripe feed; Usually feed with the feed of eel, for example the Shen Mei virtue feed formula that equals in " several kinds of feed addictive feeding Takifugu obscurus Research on effect ", to describe in 1999 is that white fish meal accounts for 56% to disclosed feed formula, starch accounts for 22%, Gluten accounts for 5%, yeast accounts for 5%, dregs of beans accounts for 3%, fish oil accounts for 1.5%, trace element, vitamin and other 7.5%; White fish meal accounts for 58% in the feed formula in " aquaculture " 2000 01 phases " fugu obscurus is to the Primary Study of mixed feed apparent digestibility ", described of Wu Bei fine jade, Shen Meifang, Yin Yue, Wu Guanghong for another example, alphalise starch accounts for 22%, yeast accounts for 5%, dregs of beans accounts for 5%, fish oil accounts for 2%, additive and other account for 8%; It is all very big to disclose the ratio that fish meal accounts in the feed formula at present; In feed, using a large amount of fish meal is the main cause that causes the fish meal resource scarcity, uses one or more fish to be raw material and fish meal is this, through deoil, high-protein feed raw material after the dehydration, grinding and processing is not high in the output of China; China's fish meal industry is because starting is late; And be mostly small-scale production, yield poorly, therefore depend on import more; In latter stage in 20th century, the annual approximately 700,000 tons of fish meal of import of China; A large amount of fish meal that use in feed owing to discharge phosphorus, nitrogen height, also cause the pollution of environment.
The shortage of fish meal resource, feasible brainstrust in the industry seeks to substitute the resource of fish meal energetically, and wherein plant protein source is easy to advantages such as acquisition because aboundresources, protein content height are arranged, and comes into one's own.
Summary of the invention:
One of the object of the invention is to disclose a kind of feed that is used for feeding Takifugu obscurus.
Another object of the present invention is the preparation method who discloses this feed.
Technical scheme of the present invention is following:
A kind of feed that is used for feeding Takifugu obscurus, wherein said feed comprise the following raw material that accounts for total weight percent: red fish meal 40%-49%, starch 22%; The combination 10%-12% of corn protein powder or the dish dregs of rice and cotton dregs, chicken meal or meat meal tankage 6%-10%, dregs of beans or peanut meal 6%-10%; Choline Chloride 0.4%-0.6%; Compound additive 2.22%, fish oil 2.7%-3.2%, flour or rice bran 0%-1%.
Feed in the technique scheme, wherein the best proportioning of each raw material is: red fish meal 46%, starch 22%; The combination 10% of corn protein powder or the dish dregs of rice and cotton dregs, chicken meal or meat meal tankage 8%, dregs of beans or peanut meal 8%; Choline Chloride 0.5%; Compound additive 2.22%, fish oil 2.9%, flour or rice bran 0.38%.
Feed in the technique scheme, the combination Chinese food dregs of rice of the wherein said dish dregs of rice and cotton dregs and cotton dregs respectively account for half the.
Feed in the technique scheme, the composition of wherein said compound additive is: coating lysine 25%, betaine 20%, B B-complex 30%, calcium dihydrogen phosphate 20%, anti-oxidant 5%.
The preparation method of the feed described in the technique scheme comprises the steps:
(1), with the dregs of beans of said mass percent or peanut meal with after Choline Chloride mixes, again with the combined hybrid of corn protein powder or the dish dregs of rice and cotton dregs, mixture A;
(2) compound additive is mixed with starch, get mixture B;
(3) mixture A is mixed with mixture B, obtain mixture C;
(4), flour or rice bran, chicken meal or meat meal tankage are mixed with fish meal, obtain mixture D;
(5), mixture C is mixed with mixture D, mixture E;
(6), the utilization feed granulator is processed mixture E the particulate material of soybean grain size;
(7), particulate material is mixed with fish oil, obtain feed.
Preparation method in the technique scheme is characterized in that: said step (7) is before the feed of throwing something and feeding, particulate material to be mixed with fish oil.
Each components in proportions of B B-complex described in the present invention is Vitaminpremix:gkg
-1Premix (content in the vitamin premix: gram/kilogram): thiamin (vitamin B1) 0.4; Riboflavin (vitamin B2) 3.1; Pyridoxine (vitamin B6) 1.0; D-Calcium pantothenic acid (calcium pantothenate) 5.0; Nicotinicacid (nicotinic acid) 5.0; Biotin (biotin) 0.05; Folic acid (folic acid) 0.18; Vitamin B12 (cobalamin) 0.005; Inositol (inositol) 5.0; Menadione (vitamin k 3) 2.0; Vitamin A (vitamin A) 20000000IU; Vitamin D3 (cholecalciferol) 400000IU; DL-a-tocopheryl acetate (dl-a-D-) 8.0.
Because adopted the preparation method of feed formula of the present invention and feed, the present invention has following beneficial effect:
1, this feed formula can be practiced thrift the fish meal resource, reduces the discharging of nitrogen phosphorus, and protection has positive role to water environment.
2, owing in this feed formula, reduced the consumption of fish meal; The minimum amount of fish meal is merely 40% in feed formula of the present invention; Can alleviate the pressure of the fish meal shortage of resources on China domestic market to a certain extent, alleviate dependence simultaneously external imported fish meal.
3, the compound additive that uses in this feed, the inside comprise trace elements such as abundant vitamin, lysine, calcium, and the growth of fugu obscurus is had positive role, have improved the speed of growth of fugu obscurus.
4, the feed among the present invention is processed the graininess of soya bean size, can improve the grazing rate of fugu obscurus, improves the utilization rate of feed.
5, each component of feed of the present invention order that feeds intake can ensure that various nutritional labelings mix; Before throwing is raised, add fish oil and can slow down in the feed in the water soluble ingredient dissolving entry, both reduced water pollution and can guarantee that also nutriment is fully by the fugu obscurus absorption of eating.
