Abstract
The invention provides low-phosphorous feed capable of improving tachysurus fulvidraco feed efficiency and protein efficiency.The low-phosphorous feed is prepared from, by weight, 25-35% of fish meal, 15-25% of soybean meal, 8-15% of corn flour, 18-24% of flour, 7% of soyabean oil, 3% of fish oil, 2% of mineral substances, 0.4% of multi-vitamins, 0.15% of monocalcium phosphate, 0.2% of a mould inhibitor, 0.2% of a binding agent, 0.2% of astaxanthin algae powder, 1% of soyabean lecithin, 0.1-0.4% of vitamin D3 premix and 0.2% of choline chloride.The low-phosphorous feed has the advantages that vitamin D3 premix and astaxanthin algae powder are used for adjusting the component matching in the feed, the tachysurus fulvidraco low-phosphorous feed efficiency and protein efficiency are improved, the usage amount of monocalcium phosphate in the tachysurus fulvidraco feed formula is reduced, nutritional requirement for tachysurus fulvidraco growth is ensured, and feed cost is reduced.
Description
Technical field
The present invention relates to Pelteobagrus fulvidraco cultural technique field, particularly relate to a kind of low-phosphorous feedstuff improving yellow-head catfish feed efficiency and protein efficiency。
Background technology
Pelteobagrus fulvidraco (formal name used at school: Pelteobagrusfulvidraco), for SILURIFORMES, section, Pelteobagrus Fish, is distributed mainly on each Pacific Ocean, Eastern China water system。The adaptive capacity of the multipair environment of Pelteobagrus fulvidraco is relatively strong, lives in the shoal of hydrostatic or unhurried current。Pelteobagrus fulvidraco feeding habits are carnivorous is the ominivore-fish led。Pelteobagrus fulvidraco delicious meat, few thorn without squama and are of high nutritive value, and have significantly high economic worth。Under the wideling popularize of the breakthrough of Pelteobagrus fulvidraco artificial propagation techniques and multiple aquaculture model, Pelteobagrus fulvidraco aquaculture industry scale is increasing, it has also become one of Main Commercial Fishes of China's freshwater aquiculture。
Research shows, Fish are big to the requirement of calcium, phosphorus, and Fish must flow through food and supplement phosphorus, therefore cultured fishes need to obtain the P elements that major part is required from feedstuff。In current aquatic feeds, the addition of Phos is generally higher than the Fish demand to phosphorus, and as Wang Chunfang has investigated the addition of phosphorus in yellow-head catfish feed equal in November, 2013, result shows, the addition of phosphorus is Pelteobagrus fulvidraco to more than the twice of the demand of phosphorus。
The water environment of the breeding water body of high-quality is that cultivation is successfully crucial。In highly intensive aquaculture, substantial amounts of aquatic feeds is devoted in water body to obtain the maximum output of cultured fishes。When Dietary phosphorus is excessive, discharged to urinate phosphorus and fecal phosphorus form by phosphorus excessive and nonabsorbable in the feedstuff of fish, become phosphorus polluter primary in breeding water body together with residual bait, aggravate breeding water body Eutrophic Extent。Big quantity research shows, phosphorus is the restriction factor of most poisons in freshwater eutrophication。Therefore, effectively control phosphorus has just become one of first-selected measure of alleviation Water Eutrophication。Relative to the various regulating and controlling water quality measures administering serious eutrophication breeding water body, exploitation low-phosphorous environment-friendly aquatic feeds, reduce the phosphorus discharge caused because of high phosphorus feedstuff of throwing something and feeding and be undoubtedly the maximally effective phosphorus content in breeding water body that the most directly reduces, the method for control body eutrophication。Wang Chunfang etc. report a kind of method reducing the discharge of Pelteobagrus fulvidraco phosphorus, and its main purpose is to make Pelteobagrus fulvidraco small intestinal that active absorption and the Passive diffusion of feedstuff phosphorus are reached optimal balance point, thus improving Pelteobagrus fulvidraco to the utilization ratio of feedstuff phosphorus, reduction feedstuff phosphorus discharge。But, as cultivation worker, while paying close attention to the discharge of feedstuff phosphorus, the pursuit to feed efficiency should do not abandoned, feed efficiency is not only and is evaluated feed nutritive value and weigh Fish to one of important indicator of utilizing status of feedstuff, more closely related with culture benefit。Feed efficiency is more high, reflects that this feed nutritive value is more high, and the object raised is more high to the utilization rate of feedstuff, then the forage volume used in breeding process reduces, and this also means that culturist's less investment for feedstuff aspect, and cultivation efficiency is just high。
In Pelteobagrus fulvidraco intensive culture process, feed cost is maximum expenditure, as while exploitation low-phosphorous environment-friendly feedstuff, improve feed efficiency and protein efficiency ratio, PER, not only can reduce the discharge of phosphorus in breeding water body, increase the income of culturist, more can promote the environmentally friendly sustainable health development of Pelteobagrus fulvidraco intensive culture industry。
Summary of the invention
It is an object of the invention to by the rational allocation of component in Pelteobagrus fulvidraco low-phosphorous environment-friendly feed formula, breaking through the restriction to Pelteobagrus fulvidraco normal growth of the Pelteobagrus fulvidraco low-phosphorous feedstuff, it is provided that a kind of low-phosphorous feedstuff improving yellow-head catfish feed efficiency and protein efficiency。Use this feedstuff can improve Pelteobagrus fulvidraco rate of body weight gain WGR (weightgainrate, %) with specific rate of increase SGR (Specialgrowthrate, %/d) and day growth speed (averagegrowthratio is called for short AGR), reference is provided for the development of the low-phosphorous yellow-head catfish feed of environmental protection。
For achieving the above object, the present invention adopts the following technical scheme that
A kind of low-phosphorous feedstuff improving yellow-head catfish feed efficiency and protein efficiency, it is characterised in that: described low-phosphorous feedstuff is by following raw material components by weight percentageMixingComposition: fish flour 25～35%, soybean meal 15～25%, Semen Maydis powder 8～15%, flour 18～24%, Oleum Glycines 7%, fish oil 3%, mineral 2%, multidimensional 0.4%, dalcium biphosphate 0.15%, antifungus agent 0.2%, binding agent 0.2%, astaxanthin algae powder 0.2%, soybean lecithin 1%, vitamin D3Pre-composition 0.1～0.4%, choline chloride 0.2%。
