Abstract
The invention provides a feed additive for enhancing the utilization efficiency and coloring effect of colorant of farmed fishes, which is characterized in that synergistic agent blended into 1 kilogram of basal feed comprises the following components by weight: at least 200 milligrams of commercial astaxanthin, and 200 to 400 milligrams of ferrous fumarate. The feed additive can remarkably improve the utilization efficiency and coloring effect of carotenoid colorant on the fishes, has the technical advantages of high technical integration, safe usage, high biological availability and good coloring effect, can improve the utilization efficiency of the carotenoid colorant for the finishes, can promote the immunity of the finishes, balances nutrition, has no chemical medicinal residue, ensures the health of fish bodies, meets the nutritional requirement of the fishes, and has large popularization value.
Description
Technical field
The present invention relates to a kind of feed addictive, the especially a kind of utilization ratio of cultured fishes colouring agent and feed addictive of coloring effect of strengthening.
Background technology
The body colour of fish determines its market value and the market demand.For this reason, many fish must be added carotenoid colorant in the feed, to keep natural body colour in the process of culturing.Yet fish are limited in one's ability to absorbing of carotenoid, and wherein most colouring agent can not be absorbed by fish, but along with ight soil excretes, cause economic waste and environmental pollution.
At present, the method for more existing raising colouring agent utilization rates.Because carotenoid is easily oxidized, in feed, add a certain amount of antioxidant, as vitamin E, can protect carotenoid colorant, improve its utilization rate.But the oxidation resistance of carotenoid colorant is stronger than vitamin E, is 100 times of vitamin E as the oxidation resistance of astaxanthin.Under the situation that carotenoid exists, vitamin E is difficult to its antioxidation of performance.And carotenoid also has the protozoa activity of vitamin A, and promptly when the hypovitaminosis A in the aquatic livestock body, aquatic livestock can transform into vitamin A with carotenoid, has directly influenced coloring effect.
In addition, vitamin E and vitamin A all belong to the higher feedstuff of price, and cost must enter into consideration during interpolation.And vitamin E in the feed and vitamin A addition have the highest limiting the quantity of, can be to the effect of fish body toxigenicity in case exceed safe range.In addition, have the characteristics of nuptial coloration, have research to adopt methyltestosterone (a kind of androgen) to promote pigment deposition, but this is the method for country's use of prohibiting according to fish.
For this reason, must develop safer, effectively promote the feed addictive of carotenoid colorant utilization rate.
Summary of the invention
The technological deficiency that purpose of the present invention exists at prior art just, a kind of utilization rate that can improve fish to carotenoid colorant is proposed, can promote the immunity of fish again, guarantee fish body health, satisfy the novel fodder additive of the nutritional need of fish.
For achieving the above object, technical scheme of the present invention is as follows: a kind of synergist that promotes carotenoid colorant to the fish coloring effect, the synergist composition that mixes in every 1kg basal feed is: commodity astaxanthin and ferrous fumarate, the weight proportion of its commodity astaxanthin is at least 200mg, and the weight proportion of ferrous fumarate is 200mg---400mg.
Ferrous fumarate belongs to nutritional feed additive, safety, bioavailability height, commodity astaxanthin in conjunction with the carrotene that belongs to natural class, can prevent that carotenoid colorant such as astaxanthin is oxidized in feed processing and digestion and metabolism process, keep its biologically active, improve the utilization rate of colouring agent, improve coloring effect.Simultaneously, ferrous fumarate can strengthen the immunity function of fish, improves the premunition of fish.Ferrous fumarate be in animal body with the form of ferrous ion after duodenum and jejunum epimere are absorbed, in marrow, participate in the synthetic of hemoglobin, fumarate ion can participate in tricarboxylic acid cycle, it is required for the metabolism of body to form ATP, or as the carbon skeleton synthesizing amino acid, and further compound body albumen.In addition, ferrous fumarate is little to the composition influences such as vitamin in the feed.
Ferrous fumarate belongs to organic acid iron, has that cost is low, a good fluidity, effective advantage, can improve growth performance.Ferrous fumarate be a kind of organically, environmental protection, source of iron additive efficiently, its bioavailability height, addition is less relatively, can reduce production costs, and improves production performance, has very big promotional value.
Coloring effect lasting stability of the present invention, cheap, by improving the utilization rate of colouring agent, can reduce and not utilize colouring agent to discharge to breeding water body, alleviate the pollution of fish culture to environment; Ferrous fumarate can strengthen the disease resistance of fish.
The specific embodiment
Embodiment one:
Get the long map fish of two groups of 10cm (i.e. eye spot Astronotus) the experiment contrast of throwing something and feeding.
After getting the commodity astaxanthin stirring and evenly mixing of ferrous fumarate, 200mg of 200mg, join in the basal feed of 1kg the map fish of the test group of throwing something and feeding behind the stirring and evenly mixing, and an astaxanthin-containing in the map fish basal feed of contrast groups.
After throwing something and feeding 30 days, the content of commodity astaxanthin in skin of determination test group map fish and the fin ray compares with the map fish of the control group that only adds astaxanthin, and the skin of test group map fish and the content astaxanthin of fin ray are 3 times of control group map fish.
By the map fish that feed prepared of the present invention is thrown something and fed, its hyperchromic effect map fish hyperchromic with only adding astaxanthin compared, and detects by analysis, and the skin of map fish and the content astaxanthin of fin ray are as follows:
Contain a ferrous fumarate and a commodity astaxanthin astaxanthin-containing
Skin: 28.24mg/kg 9.55mg/kg
Fin ray: 24.73mg/kg 6.66mg/kg
Embodiment two:
After getting the commodity astaxanthin stirring and evenly mixing of ferrous fumarate, 200mg of 400mg, join in the basal feed of 1kg, the map fish that the 5cm that throws something and feeds behind the stirring and evenly mixing is long is after throwing something and feeding 20 days, the map fish fish body skin of gained and the pigment deposition of fin ray are obvious, and the coloring effect lasting stability.All can reach effect of the present invention.
Above content is in conjunction with further describing that concrete main embodiment is done, and can not assert that concrete enforcement of the present invention is confined to these explanations.Those skilled in the art without departing from the inventive concept of the premise, some other technology of done accurately, the deduction or replace that beautify, all should belong to protection scope of the present invention.
