Description
Technical field the present invention relates to aquatic product matched field of fodder, relates in particular to adult fish buoyancy expanding granular mixed feed field in rainbow trout.
Background technology rainbow trout is a kind of cold water fishes that belongs to salmon section, originates in the U.S..Rainbow trout is cold water predacious fish, happiness inhabits in the streams, mountains and rivers that water quality is limpid, dissolved oxygen is abundant, taking aquatic insect and larva, shell-fish, small fish and shrimp, tadpole with fall into Lu Sheng insect in water as food, at the pellet of propagating the artificial dispensing of also ingesting well under condition artificially.Rainbow trout has very flourishing stomach, and enteron aisle is short, pylorospasm prosperity, swimming rapidly, suitable intensive culture, per unit area yield is very high, in Beijing, provinces and cities' large-scale cultivation such as Heilungkiang, Yunnan.
The report of domestic existing rainbow trout mixed feed patent of invention.Patent name is " a kind of rainbow trout feed ", the patent No. is that Chinese invention patent and the patent name of CN201110362591.3 is " a kind of rainbow trout fingerling feed ", although the disclosed technology such as the Chinese invention patent that the patent No. is CN201110362592.8 have distinctive technical characterstic separately, Shortcomings also aspect attractant, growth promotion.The present invention is different from published invention technology in the selection of raw material etc. and proportioning, has unique technical characterstic at the aspect such as attractant, growth promotion.
Because rainbow trout is at different growth and development stages, its nutritional requirement also exists larger difference, therefore in the cultivation of rainbow trout, general according to the different cultivation stages, the various raw materials of artifical compound feed are carried out to different scientific matching and form different mixed feeds.
Summary of the invention the object of the present invention is to provide adult fish buoyancy expanding granular mixed feed in the rainbow trout that is suitable for the middle adult fish stage that a kind of production cost is low and cultivation rainbow trout quality is higher.
For achieving the above object, adult fish buoyancy expanding granular mixed feed in rainbow trout of the present invention, is suitable for feeding the rainbow trout in adult fish stage in cultivation, and its component and weight percentage comprise:
| Fish meal | 45%～55% |
| Flour | 20%～25% |
| Expanded soybean | 3%～8% |
| FSPC | 2%～6% |
| Wheat flour strength flour | 1%～5% |
| Fish oil | 5%～10% |
| Brewer's yeast | 2.5%～5% |
| Mineral matter | 1%～2% |
| Calcium dihydrogen phosphate | 0.5%～1.5% |
| Choline Chloride | 0.4% |
| multidimensional | 0.2%. |
Wherein, fish meal mainly provides protein sources and energy, and plays good food calling effect.Because the rainbow trout in middle adult fish stage is low compared with postlarva and juvenile fish stage to the requirement of protein, therefore the content of the fish meal in the present invention relatively other in stage rainbow trout content lower, be 45%～55%, when its content is greater than 55%, feed cost strengthens, and while being less than 45%, feed conversion rate reduces.
Flour is beneficial to raw mixture shaping particles the good stability of tool while being mainly used for expanded granulation, compared with heavy property puffing granule compound feed, buoyancy expanding granular mixed feed needs the more flour of high-load.In the time that its content is greater than 25%, the crude protein of feed is reduced, while being less than 20%, particle is difficult is shaped, and feed easily sinks.
Expanded soybean, FSPC and wheat flour strength flour mainly provide protein sources and energy, and for Substitute For Partial fish meal, its addition is subject to cost impact, but feed conversion rate declines when too high levels; Wheat flour strength flour has good viscosity simultaneously, is conducive to promote feed to be shaped, and improves water stability.
Fish oil mainly provides essential fatty acid and energy, and plays food calling effect.All can increase when it adds the requirement such as technological requirement, feed storage to product when excessive, and add when not enough, the function such as energy, food calling of feed all declines.
Brewer's yeast mainly provides protein sources, and peptic function, is unfavorable for the water stability of feed in the time that addition is too high.
Mineral matter, calcium dihydrogen phosphate, Choline Chloride and multidimensional etc., all as additive, play the effect of extra-nutrition, provide rainbow trout 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 on market.
For making product efficacy of the present invention better, can in material composition of the present invention, add astaxanthin, its content is 0.1%; Emulsifying agent, its content is 0.1%; VC phosphate, its content is 0.1%; Antioxidant, its content is 0.02%; Phagostimulant, its content is 0.2%; Probiotics, its content is 0.18%.Wherein, astaxanthin is mainly used in strengthening rainbow trout pigment deposition, improves rainbow trout commodity value; Emulsifying agent mainly promotes rainbow trout digesting and assimilating fat; VC phosphate is mainly used in alleviating the loss of HTHP to VC, strengthens rainbow trout anti-stress ability; Antioxidant is mainly used in preventing that feed Raw is as oxidized in protein, fat; Emulsifying agent mainly promotes rainbow trout digesting and assimilating fat; Phagostimulant is mainly used in strengthening the food calling effect of feed, promotes that rainbow trout ingests; Probiotics is used for improving rainbow trout enteron aisle beneficial microbe colony, promotes digesting and assimilating feed.
Add man-hour, emulsifying agent is soybean lecithin powder, and antioxidant is ethoxyquinoline, and phagostimulant is betaine, probiotics bacillus subtilis and lactic acid bacteria.
Through in same plant, under identical management mode condition, adopt in the rainbow trout of following raw material components and content adult fish buoyancy expanding granular mixed feed food calling effective, fast growth, economic benefit is best, culture efficiency the best.
| Fish meal | 50% |
| Flour | 23% |
