Abstract
The invention discloses a powdery formula feed for elvers of American eels, which is suitable for feeding the American eels in the elver stage. The powdery formula feed comprises the following components: fish meal, pre-gelatinized starch, fermented soybean meal, soy protein concentrate, fish oil, immune polysaccharides, minerals, calcium dihydrogen phosphate, choline chloride, multi-vitamins and the like. The powdery formula feed for the elvers of the American eels, disclosed by the invention, has the following advantages: 1) the nutrition is comprehensive: the product is rich in various necessary protein sources, trace elements, special minerals, vitamins and the like, and can meet the demands of the American eels in the elver stage for various nutritional components; 2) the viscoelasticity is good, the stability in water is good, and the water-changing frequency is low: the various raw materials and additives are reasonably matched, the proportion of the pre-gelatinized starch is suitable, the prepared agglomerated feed is less prone to loss in the water, the pollution of a farming water body is effectively relieved and the water-changing frequency is reduced; and 3) the anti-stress ability is strong, and the farming economic benefits are good.
Description
Technical field the present invention relates to aquatic product matched field of fodder, relates in particular to eel elver powdery compound feed field.
Background technology eel originates in America east bank, be distributed in eastern North America to Guyana, Greenland.Produce seedling season in 1 annual～June, be wherein to produce seedling peak period 3～April.Along with the scarcity of Japanese eel and European eel seed resource, eel has become one of emerging common eel breed variety, and growth momentum is powerful.
In the breeding process of eel, culturist stirs the agglomerating eel of feeding afterwards with powdery compound feed.This mode of throwing something and feeding exists because feed leaches pollutes breeding water body, causes the drawbacks such as huge waste.In order to alleviate the pollution to breeding water body, reduce and change water frequency, require mixed feed to there is good viscoplasticity and water stability.This needs choose reasonable and the collocation of various raw materials in feed.
Because eel is at different growth and development stages, its nutritional requirement also exists larger difference, therefore in the cultivation of eel, 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 artifical compound feeds.
Summary of the invention the object of the present invention is to provide a kind of required powdery compound feed of eel elver stage that is applicable to, and can provide the cost of sufficient nutritional need and eel culture lower for the eel elver stage.
For achieving the above object, eel elver powdery compound feed of the present invention, is suitable for feeding the eel in elver stage, and its component and weight percentage comprise:
| fish meal | 57%～66% |
| pre-gelatinized starch | 23%～25% |
| fermented bean dregs | 3%～5.5% |
| fSPC | 3%～6% |
| fish oil | 0.5%～2% |
| immune polysaccharide | 1%～3% |
| mineral matter | 1%～2% |
| calcium dihydrogen phosphate | 0.5%～1% |
| choline Chloride | 0.3% |
| multidimensional | 0.2%. |
Wherein, fish meal mainly provides protein sources and energy, and plays good food calling effect.Due to the eel in elver stage, the requirement of protein is likend high to eel, so the content of the fish meal in the present invention wants high with respect to the content that becomes eel stage eel, is 57%～66%, when its content is greater than 66%, feed cost strengthens, and while being less than 57%, feed conversion rate reduces.
Pre-gelatinized starch is mainly used for mash feed and plays cementation when cultivation use stirs into bulk, can make feed have good viscoplasticity, and in water, keep good stability, is beneficial to ingesting of eel, and reduces and scatter and disappear.When its content is greater than 25%, the utilization rate of feed is reduced, while being less than 23%, reduce feed water stability, increase and scatter and disappear.
Fermented bean dregs and FSPC mainly provide protein sources and energy, for Substitute For Partial fish meal, reduce feed cost, and its addition is subject to cost impact, but feed conversion rate declines during too high levels.
Fish oil mainly provides energy, and plays food calling effect, all can increase, and add when not enough when it adds when excessive to requirements such as the technological requirement of product, feed storages, and the functions such as the energy of feed, food calling all decline;
Immune polysaccharide mainly improves fish body anti-stress ability and immunity, mainly contains manna oligosacchride, beta glucan etc.Addition is too high, increases feed cost.
Mineral matter, calcium dihydrogen phosphate, Choline Chloride and multidimensional etc., all as additive, play the effect of extra-nutrition, provide eel 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.
Preferably, eel elver powdery compound feed of the present invention, its component and weight percentage are:
| fish meal | 57%～66% |
| pre-gelatinized starch | 23%～25% |
| fermented bean dregs | 3%～5.5% |
| fSPC | 3%～6% |
| fish oil | 0.5%～2% |
| immune polysaccharide | 1%～3% |
| mineral matter | 1%～2% |
| calcium dihydrogen phosphate | 0.5%～1% |
| choline Chloride | 0.3% |
| multidimensional | 0.2% |
| coated vitamin C | 0.1% |
| antibacterial peptide | 0.1% |
| antioxidant | 0.02% |
| salt | 0.28%. |
For making product efficacy of the present invention better, can in material composition of the present invention, add coated vitamin C, its content is 0.1%; Antibacterial peptide, its content is 0.1%; Antioxidant, its content is 0.02%; Salt, its content is 0.28%.Wherein, coated vitamin C is mainly used in strengthening body premunition and to various adaptability that stress phenomenon; Antioxidant is ethoxyquinoline, is mainly used in preventing that feed Raw is as oxidized in protein, fat; Antibacterial peptide is mainly used in improving fish body immunity and anti-stress ability; Salt is mainly used in the osmotic pressure in balance eel body, the enteritis that simultaneously contributes to prevent eel.
Through in same plant, under identical management mode condition, adopt the eel elver powdery compound feed food calling of following raw material components and content effective, water stability is best, and economic benefit is best, and culture efficiency is best.
| fish meal | 61% |
| pre-gelatinized starch | 24% |
| fermented bean dregs | 4.5% |
| fSPC | 5% |
| fish oil | 1.5% |
| immune polysaccharide | 1.5% |
| mineral matter | 1% |
| calcium dihydrogen phosphate | 0.5% |
| choline Chloride | 0.3% |
