Summary of the invention:
The objective of the invention is, provide a kind of river crab to become the prescription of crab feed.Another object of the present invention is to provide this feed formula to make the method that river crab becomes the crab mixed feed.Become mixed feed that the crab feed formula makes to the river crab good palatability by river crab of the present invention, the water-fast bubble time is long, and the river crab fast growth of raising, feed coefficient are low.
In order to achieve the above object, the percentage by weight of river crab one-tenth crab feed formula each component of the present invention adopts: fish meal 10-40, dregs of beans 20-32, inferior powder 10-20, corn flour 5-16, various mineral salt 1-3, cuttlefish meal 1-3, oily chaff 5-15, betaine 0.1-0.3, fish oil 3-5, multivitamin 1-3, shell plain 0.1-0.3, adhesive 1-3, antioxidant 0.01, mould inhibitor 0.01.
River crab of the present invention becomes the preferred percentage by weight of crab feed formula each component to adopt: fish meal 20-36, dregs of beans 23-30, inferior powder 12-18, corn flour 8-13, various mineral salt 1.5-2, cuttlefish meal 1.5-2, oily chaff 6-12, betaine 0.1-0.3, fish oil 3-5, multivitamin 1.5-2, shell plain 0.1-0.3, adhesive 1-3, antioxidant 0.01, mould inhibitor 0.01.
River crab of the present invention becomes the percentage by weight of crab feed formula each component the best to adopt: fish meal 31.98, dregs of beans 26, inferior powder 15, corn flour 8, various mineral salt 2, cuttlefish meal 2, oily chaff 7.8, betaine 0.1, fish oil 4, multivitamin 1, shell element 0.1, adhesive 2, antioxidant 0.01, mould inhibitor 0.01.
The percentage by weight of aforementioned various mineral salt each component can adopt:
Calcium hydrophosphate fodder 50, calcium lactate 5, potassium sulfate 7, sodium sulphate 1, magnesium sulfate 5, ferrous sulfate 2, copper sulphate 0.05, manganese sulfate 0.5, zinc sulfate 0.06, aluminum sulfate 0.1, cobalt chloride 0.02, KI 0.07, sodium chloride 5, bentonite 24.2.
The multivitamin content of aforementioned per kilogram can adopt:
VA 5,400 ten thousand IU, VD3 1080IU, VE 50000mg, VK3 5000mg, VB12000mg, VB2 15000mg, VB6 30mg, VB12 30mg, VH 2000mg, nicotinic acid 30000mg, folic acid 500mg, calcium pantothenate 2500mg, Choline Chloride 5000mg, VC 300g; The rest is wheat bran.
Aforesaid shell element can adopt cholesterol, adhesive can adopt poly-many aldehyde aquatic products adhesive, antioxidant can adopt dibutyl hydroxy toluene, mould inhibitor can adopt Sodium Benzoate or sodium sorbate, the content requirement of fish meal protein matter reaches more than 60%, and the dregs of beans Protein content requires to reach more than 44%.
The method that river crab of the present invention becomes the crab feed formula to make river crab compound feed follows these steps to order and carries out:
1, become the requirement of crab feed formula each component percentage by weight to take by weighing fish meal, dregs of beans, inferior powder, corn flour, various mineral salt, cuttlefish meal, oily chaff, betaine, fish oil, multivitamin, shell element, adhesive, antioxidant, mould inhibitor by river crab;
2, fish meal, dregs of beans, inferior powder, corn flour, oily chaff, cuttlefish meal were pulverized 40 mesh sieves respectively, and put into mixer simultaneously and mix;
3, betaine, shell element, multivitamin, various mineral salt, adhesive, antioxidant, mould inhibitor are crossed 40 mesh sieves respectively, put into mixer simultaneously and mix once more;
4, add fish oil again and become crab feed formula each component to add up to the water of weight 1%-2% with river crab, add steam simultaneously, make the temperature of mixture reach 60 ℃-80 ℃, and proceed to stir;
5, with granulator mixture is made the particle that particle diameter is 1-3mm;
6, keep 60 ℃-80 ℃ temperature 15 minutes;
7, with cold wind dehydration, cooling, making the particle water content is 10%-12%, and particle temperature is reduced to room temperature, promptly makes river crab and becomes the crab mixed feed.
The present invention has the following advantages and effect: because mixed feed of the present invention has added cuttlefish meal and betaine, can lure the river crab feed into, and good palatability, river crab is liked to eat; Because adopt poly-many aldehyde as the aquatic products adhesive, mixed feed soaks 12 hours still toughness in water, the promptly water-fast bubble time is long; Because forage compounding is scientific and reasonable, so the river crab growth is fast, feed coefficient is low, and the feed coefficient of this mixed feed is 1.5-2.
River crab with the present invention's preparation becomes the crab mixed feed to be used for the raising of river crab megalops larva, can form every 100 one-tenth crab that restrains specification then; Be used for the raising of 5-10 gram crab kind, can form every 150 one-tenth crab that restrains specification then.
