The powdery compound feed is characterized by comprising the following components in percentage by weight: 45-50 percent of fish meal, 21-23 percent of pre-gelatinized starch, 5-8 percent of extruded soybeans, 6-10 percent of fermented soybean meal, 1-2 percent of fish oil, 3-5 percent of beer yeast, 1-2 percent of soybean oil, 1-3 percent of minerals, 0.2-0.5 percent of choline chloride and 1-2 percent of calcium biphosphate, wherein the percentages are percentages by weight. Compared with other compound feeds, the powdery compound feed for sturgeons has the advantages of low cost, high food calling property, high feed viscoelasticity, high water stability, quick sturgeon growth, good economic benefit and good cultivating effect.

Description

Powdery compound feed for sturgeons

Technical field

The present invention relates to the mixed feed field, relate in particular to the powdery compound feed for sturgeons field.

Background technology

Sturgeons is large-scale Important Economic fish, also is precious fingerling.The sturgeon kind that China mainly cultivates has the kinds such as acipenser schrencki, hybrid sturgeon.Along with the Progress ﹠ New Products of sturgeon artificial culture technology, sturgeon has become a kind of fish that the cultivation prospect is arranged in the aquaculture most.The scale propagated artificially of sturgeon constantly enlarges in recent years, originally uses eel compound feed to develop into gradually the sturgeon special compound feed.

In the market take the sturgeon puffing granule compound feed as main sturgeon breeding, but along with the development of soft granule technology, powdery compound feed for sturgeons also begins to use in sturgeon cultivation, has the digestive utilization ratio advantages of higher.Powdery compound feed for sturgeons also is an important directions of sturgeon feed research.

Summary of the invention

The object of the present invention is to provide a kind of required powdery compound feed of sturgeon cultivation that is applicable to, can provide the cost of sufficient nutritional need and the cultivation of growing lower for sturgeon.

For achieving the above object, the present invention is suitable for feeding sturgeon, and it is a kind of mixture of being made by the processing method of powdery compound feed by each raw material components, and its each raw material components and content comprise:

Fish meal 45% ~ 50%;

Pre-gelatinized starch 21% ~ 23%;

Expanded soybean 5% ~ 8%;

Fermented bean dregs 6% ~ 10%;

Fish oil 1% ~ 2%;

Brewer's yeast 3% ~ 5%;

Soya-bean oil 1% ~ 2%;

Mineral matter 1% ~ 3%;

Choline Chloride 0.2% ~ 0.5%;

Calcium dihydrogen phosphate 1%～2%;

All percentages are percetage by weight.

Wherein, fish meal mainly provides protein sources and energy.Because mash feed will be made mixed feed of soft granules, the moisture of mixed feed of soft granules is higher, so the protein of mash feed is had relatively high expectations.Therefore the content of the fish meal among the present invention is 45% ~ 55%, when its content greater than 55%, feed cost strengthens; When its content less than 45% the time, feed conversion rate reduces.

Pre-gelatinized starch mainly is to play cementation for mash feed when soft pellet diet is made in the cultivation use, can make feed have preferably viscoplasticity, and keep preferably stability in water, is beneficial to ingesting of sturgeon, and reduces and scatter and disappear.

Expanded soybean mainly provides protein sources and energy, and its addition is subjected to cost impact, but feed conversion rate descends during too high levels.

Fermented bean dregs is obtained after the PROCESS FOR TREATMENT by fermentation by dregs of beans, can remove ANFs, helps to improve digestive utilization ratio.Protein sources and energy mainly are provided, and its addition is subjected to cost impact, but feed conversion rate descends during too high levels.

Fish oil mainly provides energy, and plays the food calling effect, all can increase when it adds when excessive technological requirement to product, feed storage request etc., and add when not enough, and the functions such as the energy of feed, food calling all descend.

Brewer's yeast mainly provides protein sources, and peptic function, is unfavorable for the water stability of feed when addition is too high.

Soya-bean oil mainly provides energy, all can increase when it adds when excessive technological requirement to product, feed storage request etc., and add when not enough the declines such as the energy of feed.

Calcium dihydrogen phosphate is mainly used in replenishing calcium, P elements; Mineral matter and Choline Chloride etc. play the effect of extra-nutrition all as additive, provide the fish body necessary trace element, promote the metabolism of fish body, and its addition is all not high.

Above-mentioned various raw material components all can be purchased in market.

For making product efficacy of the present invention better, can add in addition the fishing multidimensional in its raw material components, its content is 0.3%; Liver protectant, its content are 0.18%; Antioxidant, its content are 0.02%.Wherein, fishing mainly provides multivitamin with multidimensional, regulates sturgeon immunity; Liver protectant promotes digestion mainly for the protection of the sturgeon liver and gall; Antioxidant is mainly used in preventing feed Raw such as protein, fatty oxidized.Above-mentioned each raw material components is indium addition.

Add man-hour, generally adopt bile acid as liver protectant, antioxidant then generally adopts ethoxyquinoline.

Also can be added with the Kelp Powder that is beneficial to pigment deposition in the raw material components of the present invention, make the sturgeon breeding body colour near natural effect, its content is 2%.

Through in same plant, under the identical management mode condition, adopt the powdery compound feed for sturgeons cost of following each raw material components and content to descend at most, culture efficiency is best:

Fish meal 50%;

Pre-gelatinized starch 23%;

Expanded soybean 6%;

Fermented bean dregs 6%;

Fish oil 2%;

Brewer's yeast 5%;

Soya-bean oil 1%;

Mineral matter 2%;

Choline Chloride 0.5%;

Calcium dihydrogen phosphate 2%;

Fishing multidimensional 0.3%;

Liver protectant 0.18%;

Antioxidant 0.02%;

Kelp Powder 2%;

All percentages are percetage by weight.

Advantage of the present invention is: adopt powdery compound feed for sturgeons of the present invention with respect to other mixed feeds, cost is low, and attractant is good, and glutinousness of feed is good, and water stability is good, and the sturgeon growth is fast, and good in economic efficiency, culture efficiency is good.
