Summary of the invention
The objective of the invention is to the above technical problem that will solve, a kind of safety and Health, natural environmental-protective are provided, can effectively improve the mixed feed of golden butterfish body colour.
Another object of the present invention provides a kind of method for preparing this mixed feed.
The objective of the invention is to realize through following technological means:
A kind of mixed feed that can improve golden butterfish body colour comprises following components in weight percentage:
Fish meal 40~45%, fermented bean dregs 8~10%,
Corn protein powder 5~10%, corn 20~25%,
Peanut cake 5~8%, calcium dihydrogen phosphate 2~3%,
Rice bran meal 5~8%, fish oil 4~5%,
Vitamin premix 1~2%, mineral substance premix 1~2%.
As a kind of preferred implementation of the present invention, said mixed feed is processed by following components in weight percentage:
Fish meal 40%, fermented bean dregs 10%,
Corn protein powder 9%, corn 22%,
Peanut cake 5%, rice bran meal 5%,
Calcium dihydrogen phosphate 2%, fish oil 5%,
Vitamin premix 1%, mineral substance premix 1%.
According to mixed feed provided by the invention, said vitamin premix comprises vitamin A, vitamin D, vitamin B1, vitamin B2, folic acid, biotin, inositol, nicotinic acid, calcium pantothenate, vitamin E, prokeyvit, vitamin B6, cobalamin and defatted rice bran.
Further, contain vitamin A 10g, vitamin D 60g, vitamin B1 15g, vitamin B2 15g, folic acid 5g, biotin 28g, inositol 200g, nicotinic acid 96g, calcium pantothenate 62g, vitamin E 140g, vitamin K 33g, vitamin B6 40g, vitamin B1 29g, defatted rice bran surplus in per 1 kilogram of said vitamin premix.
According to mixed feed provided by the invention, said mineral substance premix is the mixture of ironic citrate, white vitriol, Potassiumiodate, manganese sulfate monohydrate, potassium chloride, cupric sulfate pentahydrate, sodium selenite, seven water manganese sulfates and zeolite powder.
Further, contain ironic citrate 18g, white vitriol 20g, Potassiumiodate 10g, manganese sulfate monohydrate 18g, potassium chloride 5g, cupric sulfate pentahydrate 35g, sodium selenite 20g, seven water manganese sulfate 0.5g, zeolite powder surplus in per 1 kilogram of said mineral substance premix.
The present invention also provides a kind of method for preparing this mixed feed, comprises following concrete steps:
1) quantitatively takes by weighing each raw material components;
2) all raw materials are mixed after, be crushed to the screen cloth that all feed particles all can be passed through 160~200 μ m;
3) steam that feeds 95~100 ℃ was modulated 2~3 minutes, under 100~105 ℃ temperature, carried out extrusion then;
4) under 85~90 ℃ of conditions, feed granules is dried;
5) cooling, packing.
The present invention adds corn protein powder, fermented bean dregs in the golden butterfish feed to as feedstuff, replaces adding artificial color.Wherein, corn protein powder contains the natural colouring matter that helps improving golden butterfish body colour; Dregs of beans can be removed ANFs such as most of trypsin ihhibitor, tannin after by fermentation.Experimental result shows, adds corn protein powder, fermented bean dregs in the golden butterfish feed to, can improve golden butterfish pigment deposition, makes golden butterfish reach natural body colour.Compare with existing golden butterfish mixed feed, mixed feed provided by the invention can effectively improve golden butterfish body colour, guarantees environmental-friendly natural and health simultaneously, avoids human because of taking in the multiple disease that artificial color causes indirectly.

Use golden butterfish mixed feed that embodiment 1~4 provides and commercially available interpolation to feed with the mixed feed that does not add artificial color, subjects is a 100g gold butterfish, raises and train after 1 week branch mailbox at random, every case 100 tails, and it is 3 parallel that each processing is respectively established.Formally throw something and feed and carry out pilot study before the experiment and measure its amount of being satiated with food, regularly confirm the rate of throwing something and feeding by the feeding volume of measuring of being satiated with food during formal experiment beginning, day throw something and feed 2 times (9:00,16:00), culture the 500g body weight.Its body colour is observed in the fishing back.Experimental result is following:
Experimental result shows, golden butterfish body colour and natural golden butterfish body colour that the mixed feed that adopts the embodiment of the invention 1~4 to provide is thrown something and fed are approaching, and it is too shallow not add the conventional mixed feed color of pigment, and the mixed feed color of interpolation artificial color is too dark.Therefore, mixed feed provided by the invention can effectively improve the body colour of raising golden butterfish, and healthy and safe, natural environmental-protective.
The present invention is not limited to above-mentioned embodiment; If various changes of the present invention or modification are not broken away from the spirit and scope of the present invention; If these are changed and modification belongs within claim of the present invention and the equivalent technologies scope, then the present invention also is intended to comprise these changes and modification.
