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 the increase of people to the Pelteobagrus fulvidraco demand, 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, behind its membrane 5 days, generally be to culture with the feed (as 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 by ingest zooplankter and artificial feeding.
Chinese invention patent 200610040418.0 " Yellow cartfish adult feedstuff " (the open date: on October 11st, 2006), " 200610040419.5 the feed of a kind of Pelteobagrus fulvidraco " (open date: all disclose a kind of body colour guarantor look that is used to realize Pelteobagrus fulvidraco on October 11st, 2006), thereby improve the artifical compound feed of its commercial value, wherein patent of invention " Yellow cartfish adult feedstuff " is by add cupric in feed, iron, manganese, the salt of zinc, patent of invention " feed of a kind of Pelteobagrus fulvidraco " are to reach the purpose of protecting look by a certain amount of corn protein powder of adding and shrimp shell meal in feed.The disclosed Pelteobagrus fulvidraco mixed feed of these two patents, patent of invention " Yellow cartfish adult feedstuff " is a 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 a 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, and the content of fish meal is on the low side in the above-mentioned patent, has reduced protein and amino acid whose content 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 (as brewer's yeast, flour etc.) of the enterprises engaged in processing agricultural products (as 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 by soya-bean oil, rape oil to providing of fish energy is provided, 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, Fujian relatively particularly, its production cost is higher, aquaculture cost is also higher.
Summary of the invention
The object of the present invention is to provide a kind of production cost and be used for all lower and higher Yellow cartfish adult expanded pellet feed that is suitable for the Yellow cartfish adult stage breeding of breed Pelteobagrus fulvidraco quality of cost that Pelteobagrus fulvidraco is cultured.
For achieving the above object, the present invention is suitable for feeding the Pelteobagrus fulvidraco in adult fish stage, be body weight the Pelteobagrus fulvidraco in 20 gram above adult fish stages, it is a kind of mixture of being made by the processing method of expanded pellet feed by each raw material components, and its each raw material components and content comprise:
Fish meal 36%～40%
Flour 15.58%～19.6%
Cotton dregs 3.5%～4%
Dregs of beans 16%～20%
Corn protamine 6%～7%
Fish oil 4.5%～5.5%
Brewer's yeast 6%～7%
Mineral matter 1%～1.5%
Choline Chloride 0.5%～0.6%
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.But the final method of checking prescription is still in actual production, and it all is important indicators of judging that aquatic products use back fast growth, feed efficiency height, the death rate low, good in economic efficiency etc.
As Feed Enterprise, reduce cost, generating profit maximization is one of important target.The present invention compares with existing mixed feed, all has obvious benefit on the determining of the selection of its raw material components and proportioning:
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 amino acid whose content, improved the attractant of feed; Simultaneously since the Pelteobagrus fulvidraco in adult fish stage to the requirement of crude protein than other in stage Pelteobagrus fulvidraco low, so the content of the fish meal among the present invention is 36%～40%.
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 production of fodder 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 Yellow cartfish adult digestion, therefore the content of controlling cotton dregs is 3.5%～4%, the content of dregs of beans is 16%～20%, the content of corn protamine is 6%～7%, 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 (as brewer's yeast, flour etc.) of the more enterprises engaged in processing agricultural products (as 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 15.58%～19.6%, 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, can also provide lot of energy simultaneously, in actual production, compares with vegetable oil, and fish oil all is better than 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, be significantly higher than vegetable oil feed group (p＜0.05) and (see " Wang Jiteng; Han Tao; work such as Tian Lixia; " influence that 3 vegetable 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.
