Background technology
Pelteobagrus fulvidraco (Pelteobagrus fulvidraco Rich) is under the jurisdiction of SILURIFORMES, Crocodylidae, Pelteobagrus fulvidraco genus; Have another name called yellow loud, high-pitched sound, yellow Buddhist nun, Huang Lading etc.; Being distributed widely in China the Changjiang river, the Yellow River, the Zhujiang River and Heilongjiang river, is common small-sized fresh water bottom economic fish in the waters such as China's rivers, lake, reservoir, irrigation canals and ditches.
Natural Pelteobagrus fulvidraco belongs to the gentle carnivorous small fishes of bottom, and its edibility is higher, also has certain medical value.In recent years, Along with people's is to the increase of Pelteobagrus fulvidraco demand, and wild Pelteobagrus fulvidraco can not have been satisfied the demand in market, and people begin to adopt agalactous method to culture Pelteobagrus fulvidraco.Pelteobagrus fulvidraco to the postlarva stage; Beginning in 5 days behind its membrane; Generally be to culture with the feed (like wheel animalcule, Copepods, chironomus larvas etc.) of yolk and so on, but the Pelteobagrus fulvidraco ubiquity aquaculture cost of propagating artificially is higher, fish bulk-growth speed is slow and the not high phenomenons of quality such as body colour is turned white, burnt hair through ingest zooplankter and artificial feeding.
Chinese invention patent 200610040418.0 " Yellow cartfish adult feedstuff " (the open date: on October 11st, 2006), 200610040419.5 " feeds of a kind of Pelteobagrus fulvidraco " (the open date: on October 11st, 2006) thus in all disclose and a kind ofly be used to realize that the body colour of Pelteobagrus fulvidraco protects the artifical compound feed that look improves its commercial value; Wherein patent of invention " Yellow cartfish adult feedstuff " is through in feed, adding the salt of cupric, iron, manganese, zinc, and patent of invention " feed of a kind of Pelteobagrus fulvidraco " is to reach the purpose of guarantor's look through in feed, adding a certain amount of corn protein powder and shrimp shell meal.The disclosed Pelteobagrus fulvidraco mixed feed of these two patents; Patent of invention " Yellow cartfish adult feedstuff " is fish meal 18%～26%, dregs of beans 12%～20%, the dish dregs of rice 6%～15%, cotton dregs 6%～12%, wheat bran 10%～16%, inferior powder 0%～15%, shrimp shell meal 2%～5%, corn protein powder 4v～10%, corn 4v～10%, soya-bean oil 1%, rape oil 1%, calcium dihydrogen phosphate 2%, additive 1%; Patent of invention " feed of a kind of Pelteobagrus fulvidraco " is fish meal 20%～30%, dregs of beans 10%～20%, the dish dregs of rice 5%～15%, cotton dregs 5%～10%, wheat bran 6%～18%, inferior powder 0%～10%, blood meal 0%～5%, shrimp shell meal 8%～10%, corn protein powder 5%～10%, corn 8%～10%, soya-bean oil 1%, rape oil 1%, calcium dihydrogen phosphate 2%, additive 1%; But it is when concrete the use; When particularly using, exist following deficiency in the area, Fujian:
1, fish meal is the favorite feedstuff of aquatic livestock.Pelteobagrus fulvidraco belongs to the bottom predacious fish, likes the feed of ingestion animal property, and the content of fish meal is on the low side in the above-mentioned patent, has reduced protein and content of amino acids in the feed, and the attractant of feed is had certain influence.
2, Fujian belongs to the deficient relatively area of agricultural resource; Raw materials such as the dish dregs of rice are less relatively; The fish culture enterprise in area, Fujian generally all selects the processing byproduct (like brewer's yeast, flour etc.) of the enterprises engaged in processing agricultural products (like beer enterprise, grain and oil enterprise etc.) suitable, that price is low relatively, that the quantity quality is secure to be used as the breeding feed raw material of fish nearby, thereby reaches the purpose that reduces cost.
3, above-mentioned patent is main through soya-bean oil, rape oil to culturing providing of fish energy, but the content of contained unrighted acid is on the low side in the soya-bean oil, rape oil, a little less than energy provides.
4, traditional mixed feed is bigger to the pollution of breeding water body, and it is relatively poor to culture digesting and assimilating of fish.And emerging expanded pellet feed because have that production cost is low, digestive utilization ratio is high, aquaculture cost is low, to breeding water body pollute less, advantage such as raw material source is extensive, demonstrate huge market potential gradually in the fish feed field.
In a word; Though protecting on the look in the Pelteobagrus fulvidraco body colour, the foregoing invention patent has certain effect; But aspect the contaminative of the growth performance of culturing the fish body, breeding water body certain deficiency is being arranged, the breed user in area, particularly relative Fujian, its production cost is higher, aquaculture cost is also higher.
Summary of the invention
The cost that the object of the present invention is to provide a kind of production cost integral body lower, Pelteobagrus fulvidraco when using to culture is also lower, and the higher swelling granular mixed feed for postlarva of pelteobagrus fulvidraco that is suitable for Pelteobagrus fulvidraco postlarva stage breeding of the Pelteobagrus fulvidraco quality of culturing out.
For realizing above-mentioned purpose; The present invention is suitable for feeding the Pelteobagrus fulvidraco in postlarva stage; Be that body weight restrains to the Pelteobagrus fulvidraco in the postlarva stage of 2 grams 0.2, it is a kind of mixture of being processed by the processing method of expanded pellet feed by each raw material components, and its each raw material components and content comprise:
Fish meal 50%～55%
Flour 18.48%～20.4%
Cotton dregs 1%～2.5%
Dregs of beans 11%～15%
Corn protamine 1%～2%
Fish oil 2.5%～3.5%
Brewer's yeast 4%～5.5%
Mineral matter 0.9%～1.5%
Choline Chloride 0.4%～0.7%
Multidimensional 0.2%
All percentages are percetage by weight.
The feed formula of aquatic products of the same race is along with different choice, its proportioning of raw material are different.But finally all be with reference to certain standard, Pelteobagrus fulvidraco has the standard (SC/T 1070-2004) on the industry, has stipulated the various nutritive index limit values in the mixed feed.Generally speaking, require nutritive index (protein, fat etc.) and safety and sanitation index to meet standard.Employed which kind of raw material in the prescription there is not concrete requirement.Still in actual production, but aquatic products use back fast growth, feed efficiency is high, the death rate is low, good in economic efficiency etc. all is important indicators of judging to the final method of checking prescription.
As Feed Enterprise, reduce cost, generating profit maximization is one of important target.The present invention compares with existing mixed feed, on the confirming of the selection of its raw material components and proportioning, all has obvious benefit:
1, increases the content of fish meal, be higher than the content of fish meal in patent of invention " Yellow cartfish adult feedstuff " and " feed of a kind of Pelteobagrus fulvidraco ", can increase Protein content in the feed like this, enriched content of amino acids, improved the attractant of feed; Simultaneously since the Pelteobagrus fulvidraco in postlarva stage to the having relatively high expectations of crude protein, so the content of the fish meal among the present invention relatively other in stage Pelteobagrus fulvidraco content higher, be 52.5%～55%.
2, owing to all use fish meal can increase the production cost and the aquaculture cost of feed greatly,, reach the purpose that reduces the Feed Manufacturing cost so the present invention selects can increase equally dregs of beans, corn protamine, the cotton dregs of dietary protein level; The corn protamine is also more remarkable to the pigmentation of Pelteobagrus fulvidraco body colour simultaneously.But because the assorted dregs of rice such as cotton dregs are unfavorable for the digestion of Pelteobagrus fulvidraco postlarva; Therefore the content of controlling cotton dregs is 1%～2.5%; The content of dregs of beans is 11%～15%, the content of corn protamine is 1%～2%, all is lower than the content of cotton dregs, dregs of beans and corn protamine in patent of invention " Yellow cartfish adult feedstuff " and " feed of a kind of Pelteobagrus fulvidraco ".
3, in the raw material of feed; Selected the processing byproduct (like brewer's yeast, flour etc.) of the more enterprises engaged in processing agricultural products (like beer enterprise, grain and oil enterprise etc.) in area, Fujian; Belong to the raw material of agricultural product category and abandoned the area, Fujian than the deficient dish dregs of rice, wheat bran, corn etc., thereby ensured price, the quality and quantity of feedstuff.Wherein brewer's yeast mainly provides protein sources, and peptic function.
4, flour (promptly formerly " the inferior powder " described in the patent) belongs to the feed of energy aspect, and content of starch is higher, has viscosity.The content of flour is higher among the present invention; Be 18.48%～20.4%; The content that is higher than flour in patent of invention " Yellow cartfish adult feedstuff " and " feed of a kind of Pelteobagrus fulvidraco " the content and energy of carbohydrate, has also utilized the viscosity of flour in improving feed.Because the present invention adopted expanded processing technology, do not scatter when making expanded feed, and stability is preferably arranged in water, just need to add the strong raw material of viscosity; In addition, the flour price is relatively low, under the prerequisite that reaches nutritive index requirement and processing technology, can be used as the fine setting filler of proportioning.
5, fish oil is rich in unrighted acid, simultaneously lot of energy can also be provided, and in actual production, compares with vegetable oil, and fish oil all is superior to vegetable oil at aspects such as growth promotion, raising aquatic product qualities; Fish oil is also more remarkable to the pigmentation of Pelteobagrus fulvidraco body colour simultaneously.Wang Jiteng etc. have studied seawater fish oil and vegetable oil is formed cobio juvenile growth, body and the influence of tissue fat acid composition, find that the vegetable oil feed has reduced the quality of cobio product; Fat source has produced remarkable influence to the growth of cobio; The fish oil feed has maximum rate of body weight gain and best feed conversion rate, is significantly higher than vegetable oil feed group (p＜0.05) and (sees " Wang Jiteng, Han Tao; work such as Tian Lixia; " influence that 3 kind of plant oil sources are formed cobio growth, body composition and aliphatic acid " [J], Oceanography Institute Of Zhejiang's journal (natural science edition), 2007,26 (3): the 237-244 page or leaf).Therefore raw material of the present invention has been selected fish oil for use, and has abandoned vegetable oil such as soya-bean oil, rape oil.
6, mineral matter, Choline Chloride and the multidimensional etc. in the raw material of the present invention play the effect of extra-nutrition all as additive, and fish body trace elements necessary is provided, and promote the metabolism of fish body, and its addition is all not high.Simultaneously because technology of the present invention is bulking process, need carry out the high temperature modulation, high-pressure extrusion is expanded, and is bigger to the loss of vitamin, therefore increased the content of multidimensional, to satisfy the demand of Pelteobagrus fulvidraco to vitamin.
