Description

Mandarin sturgeon synthetic diet and production method thereof

The present invention relates to a kind of mandarin sturgeon synthetic diet and output method thereof, belong to artificial synthetic diet technical field.

Mandarin sturgeon is that a national class watches for animals, and is in the Changjiang river in the past and ocean breeding and growth always.Along with the reach of science and artificial feeding development of technology, in recent years according to the mandate of Chinese aquatic science institute, the research that we begin to propagate artificially.Originally, the feed that we adopt the breed of mandarin sturgeon is: throw something and feed after smashing with some simple meats, perhaps directly throw in some small fish that give birth to by the sturgeon free choice feeding.Raise sturgeon with this feed, exist sturgeon to grow slowly, feed the high shortcoming of cost.

Purpose of the present invention is to make mandarin sturgeon grow soon, feed low mandarin sturgeon synthetic diet and the production method thereof of cost in order to provide a kind of.

Purpose of the present invention can reach by taking following measure: a kind of mandarin sturgeon synthetic diet, be characterized in forming: whole fish meal by following raw material, soy bean powder, meat section powder, the spraying blood meal, beer yeast powder, whey powder, big dregs of beans, rapeseed dregs, inferior powder, algin, soybean lecithin adds soya-bean oil, refining seawater fish oil, calcium dihydrogen phosphate, Choline Chloride, grease parcel vitamin and synthetic additive, hundred parts of ratios of the composition of described each raw material are: whole fish meal 35～55, soy bean powder 8～20, meat section powder 5～14, spraying blood meal 4～7, beer yeast powder 2～4, whey powder 6.5～8.5, big dregs of beans 8～12, rapeseed dregs 8～12, inferior powder 2.3～4.5, algin 0.5～1.5, soybean lecithin adds soya-bean oil 1～6, refining seawater fish oil 2～4, calcium dihydrogen phosphate 0.5～1, Choline Chloride 0.25～0.45, grease parcel vitamin 0.035～0.045, synthetic additive 0.3～0.5.

The production method of foregoing mandarin sturgeon synthetic diet is characterized in carrying out as follows:

1) by the good whole fish meal of aforementioned formula weighing, soy bean powder, meat section powder, spraying blood meal, beer yeast powder, whey powder, big dregs of beans, rapeseed dregs, inferior powder base stock, pulverizes, make powder base;

2) add soya-bean oil, refining seawater fish oil, calcium dihydrogen phosphate, Choline Chloride, grease parcel vitamin and synthetic additive by the good algin of aforementioned formula weighing, soybean lecithin, and with it with 1) go on foot the powder base of making and mix, make compound;

3) compound is fully stirred evenly and inspects by random samples chemical examination;

4) the sampling observation chemical examination is qualified, and compound is pressed into granular semi-finished product;

5) granular semi-finished product are carried out post curing, make the slaking semi-finished product;

6) semi-finished product after the slaking are dried processing;

7) spot-check after the cooling;

8) finished product packing.

This mandarin sturgeon synthetic diet has following outstanding advantage:

1, can make sturgeon required graininess in each period, feed is difficult for being dissolved in water after dropping into water, helps sturgeon and looks for food, and improves palatability and makes that sturgeon is easy to search for food;

2, synthetic diet nutrition is complete, is fit to the nutritional need of sturgeon growth phase, improves speed of production;

3, price of deed rate height, meat feed ratio can obviously be increased economic efficiency at 1: 2.5;

4, contain various trace elements, play the effect of preventing and curing diseases, improve into efficient;

5, this prescription raw material source is wide, not limited by natural endowment, can satisfy the industrial aquaculture demand.

Following table is three specific embodiments of the present invention:
