The loach feed of high density large-scale breeding
Technical field
The present invention relates to the feed of culture fishery, relate in particular to a kind of loach feed of high density large-scale breeding.
Background technology
Loach (Misgurnus anguillicaudatus) belongs to Cypriniformes, Cobitidae, and flower loach subfamily, loach belongs to.Be commonly called as: loach, loach.English name: Oriental weatherfish.Its delicious flavour, fine and tender taste, nutritious, be a kind of high protein, low-fat high-grade aquatic products, be described as " genseng in the water ", the title of " ringdove in the sky, underground loach " is arranged, well imagine suitable the enriching of nutritive value of loach; Pharmaceutically also have higher value, the traditional Chinese medical science thinks that the loach flavor is sweet, property flat, beneficial gas, clearing damp detoxifcation, nourishing Yin and clearing heat, vein relaxing invigorating kidney qi in transferring.Put down in writing in the Compendium of Material Medica, loach has the effect of " beneficial gas in warm ", the wine that can quench one's thirst, diuresis, establishing-Yang, receipts hemorrhoid.That layer synovia of living loach outside can clearing liver, cholagogic, anti-inflammatory, and be helpful to hepatitis, cholecystitis.Because severe contaminations such as chemical fertilizer, agricultural chemicals, three industrial wastes cause the wild resource of loach to fall sharply now, the originally simple resource that relies on wild loach to provide can not satisfy modern humans's demand.Human living standard's raising, and in lifely also carry out the transition to matter from amount.Loach nutritious also receives the favor of numerous people gradually, and states such as Japan, Korea S, Malaysia are in a large number to China import loach at present, and demand is more than 500,000 tons, and light relies on wild resource even Chinese demand is all not enough, says nothing of to have exported.Therefore, the nuisanceless raising of manual scale high density has become the inevitable choice that satisfies domestic and international market demand, promotion human body health, safeguards ecological environment.
Summary of the invention
The objective of the invention is: a kind of loach feed of high density large-scale breeding is provided,, takes into full account requirement the quality requirement and the high density large-scale breeding of loach product according to life characteristic and the growth rhythm of loach; Utilize biotechnology to produce loach feed, digesting and assimilating and efficiency of feed utilization of enriched nutritive makes loach under the high density large-scale breeding; Fast growth, survival rate is high, and the price of deed is high; Drug residue free, good in economic efficiency.
For achieving the above object, technical solution of the present invention is that this loach feed is made up of following constituent mass percentage: dregs of beans 10.0, steam fish meal 2.0, the dish dregs of rice 15.7, cotton dregs 16.6; Rice bran 10.0, wheat 15.0, calcium dihydrogen phosphate 1.6, wheat bran 8.0, monosodium glutamate yeast 1.5; Meat meal tankage 6.0, system chaff 2.0, the plumule dregs of rice 4.0, maize alcohol stillage 3.6, phosphatide oil 1.5; Lysine 0.1, premix 1.0, Chinese herb feed additive 0.4, zeolite 1.0 adds up to 100%.
Wherein, above-mentioned premix is made up of following weight percentages of components: vitamin A 0.47, vitamin B1 0.04, vitamin B2 0.3, vitamin B6 0.1; Cobalamin 0.07, calcium pantothenate 0.25, nicotinic acid 0.35, folic acid 0.02, choline 2.00; Biotin 0.2, ferrous sulfate monohydrate 3.3, basic copper chloride 3.6, monohydrate zinc sulphate 2.3, manganese sulfate 1.2; The iodine 0.35 of mass concentration 1%, the selenium 0.35 of mass concentration 1%, zeolite 85.1 adds up to 100%.
Wherein, the said herbal medicine additive is made up of following weight percentages of components: rheum officinale 25, and the Radix Astragali 15, golden cypress 15, Radix Glycyrrhizae 15, the coptis 10, the root of large-flowered skullcap 20 adds up to 100%.
Feed ingredient is produced pellet according to normal aquatic granulated feed processing method in proportion, directly feed for loach according to the normal feeding method of loach again.
The present invention has following outstanding advantage and technique effect:
(1), raw material that the present invention adopted do not contain any violated agricultural chemicals and chemicals composition, and is safe and reliable.
(2), the present invention uses Chinese herbal and crude drugs preparations to replace the common chemical medicine, thereby prevent chemicals residual in the loach body effectively, guarantee that product meets the sanitary index requirement to loach.
(3), the present invention can guarantee the growth needs of loach under high density large-scale breeding condition, promotes digesting and assimilating of nutriment, improves the utilization rate of energy, albumen to greatest extent; Reduce aquaculture cost; Increase economic efficiency, reduce emission of harmful substances, keep the stable of water quality; Guarantee the good water body environment of fish body, promote the healthy growth of fish body.
(4), the present invention can make the feed rate that digests and absorbs improve 10~15%, feed coefficient descends 8~10%, the feed integrated cost descends 10~12%.
The specific embodiment
Embodiment below in conjunction with concrete is further described the present invention, and these embodiment can not be interpreted as the qualification to technical solution of the present invention.
Embodiment: comply with following raw material and 1000 kilograms of feeds of the present invention of Additive Production:
