Description

Feed for eel {feed for ell}

The present invention relates to feed for eel farming.

Recently, as the awareness that seafood is a health food spread, the consumption of aquatic products has increased, and fish farming has also increased in quantity.

Eel is a high protein stamina food and contains a lot of vitamins A, B and E. In addition, eel fat contains abundant DHA 1332mg, EPA 742mg and lecithin. Lecithin is the main component of the human cell membrane and is indispensable for brain cells.

The eel is divided into several stages of growth, and it is a unique species that cannot artificially spawn and hatch. Because of its physiological characteristics, eel must be caught in the middle stage of growth and cultured in a suitable environment. In the process, various infectious diseases such as bacterial diseases and parasitic diseases due to the mass density of aquaculture are caused, and many cases of farmed eel die.

In order to prevent this, antibiotics are added to feed or water for farming in order to prevent or treat diseases. However, this causes a problem of deteriorating food stability and worsening disease resistance. In recent years, researches on natural substances that can enhance immunity while being suitable for aquaculture fish have been steadily progressed to improve these problems. However, the development of suitable substances for applied fish is still insufficient.

On the other hand, Patent No. 0585500 discloses aquaculture freshwater eel feed additives and aquaculture freshwater eel feed comprising the same.

The disclosed aquaculture freshwater eel feed additive consists of a mixture chitosan oligosaccharide derivative obtained by hydrolyzing a mixture of Ganoderma lucidum extract added to chitosan. However, these additives can increase the immunity, but there is a disadvantage that the therapeutic effect against trauma that may be caused by mutual contact in the process of dense breeding is relatively low, and is not suitable as a mass additive feed additive.

The present invention is to solve the problems as described above, while containing the additives for eel farming feed additives that can improve the immune capacity and anti-history of eel and increase the healing effect on trauma that can be caused by dense breeding The purpose is to provide an eel farm food.

Eel culture feed according to the present invention for achieving the above object is 49% by weight crude protein, 3% by weight crude fat, 2% by weight calcium, 2.7% by weight, 3% by weight crude fiber, 18% by weight ash, squid meat The feed additive is added in an amount of 0.01 to 0.2 parts by weight based on 100 parts by weight of the basic feed consisting of 22.3% by weight, and the feed additive is dried mulberry leaves, mulberry branches, and mulberry trees, dried to have a water content of 15 to 20%. 360 grams of mulberry mixed with the same weight ratio of roots, dried to the water content of 15 to 20% 270 grams of the lotus leaf and lotus root cut at the same weight ratio and dried to 15 to 20% moisture content The mixture was mixed with 380 grams of ivy chopped and added to water having a weight of 5 to 7 times to precipitate an extract extracted at low temperature by 85 to 90 ° C., and then the filtrate was filtered and concentrated to 300 cc. .

Preferably, the feed additive is mixed with the water so as to further include 11 to 13 parts by weight of tomatoes mixed with 100 parts by weight of the mixed tomato stem and leaves cut to dry at a water content of 15 to 20% by weight. Apply the extracted data.

In addition, the feed additive is applied to the extracted by mixing in the water further comprises 8 to 12 parts by weight of the dried and cut to a water content of 15 to 20% to 100 parts by weight of the mixture.

As described above, according to the feed mixed with the additives and additives for eel culture according to the present invention, the immunity of the eel is improved during the aquaculture process, the mortality is significantly reduced, and the use of antibiotics can be suppressed, and the occurrence of wounds is prevented. Fast healing provides almost no scars on the appearance and provides the advantage of increasing growth efficiency.

Hereinafter, a preferred embodiment of the eel cultured feed according to the present invention will be described in detail.

The feed for eel culture according to the present invention consists of a basic feed and a feed additive, the feed additive is 35 to 37% by weight of the mulberry extract extracted from the mulberry, 25 to 27% by weight of the extract extracted from the lotus, ivy extract 37 extracted from the ivy vine To 39 weight percent.

The mulberry extract is applied to the extract from the mulberry leaves, mulberry branches, mulberry root.

Mulberry leaves contain water, carbohydrates, proteins and 25 amino acids, and reduce cholesterol, prevent and reduce fat, and the branches and roots of mulberry, which remove poisons, alanine and hemorrhagic diseases Routines that prevent and include a variety of substances that enhance immunity.

The lotus extract is extracted from lotus root and lotus leaf.

The kite contains alkaloids such as romerin, luciferin, anodine, and armeparin, d-n meticolaurin, quercekin, isoquicetin, flavonoids, natural organic acids such as tartaric acid and citric acid, and vitamins.

In particular, roemerine and luciferine contained in lotus leaf and lotus root have sedative effects and relieve stress of eel during dense rearing process. In addition, the lotus root is rich in vegetable fiber, which stimulates the barrier moderately to activate the intestinal activity and lower the body's cholesterol level

If you do, iron and tannin components contained in the lotus root is excellent anti-inflammatory action to reduce the inflammation of mucosal tissues can increase the healing power of trauma generated in the dense rearing process of eel.

Ivy extract is applied to extract from the ivy vine.

Ivy is an antioxidant that contains resveratrol.

In addition, the ivy is sweet in the stem and functions to relieve blood, pain. The ivy extract extracted from these ivy vines increased the appetite of the eel by the sweetness, it was confirmed that the healing power for trauma is also excellent.

Ivy vines are those that have been harvested on pine for more than three years.

Such mulberry extract, lotus extract and ivy extract may be applied to the powdered by drying the material and finely chopped, or by applying an extract concentrated by distillation extraction method using water or alcohol.

In case of extracting and applying the extract, the material is mixed with water and extracted by low temperature heat extraction at 85-90 ℃ for about 4 hours, and the precipitated primary extract is precipitated, filtered and concentrated by heating the primary extract again. Apply it.

On the other hand, with respect to 100 parts by weight of the mixture mixed with mulberry extract, lotus extract and ivy extract, it is preferable to further include 11 to 13 parts by weight of the tomato extract extracted from the tomato stem and leaves.

Extracts extracted from tomato stems and leaves were found to have an effect of inhibiting the growth of germs or worms present in the water quality of fish farms.

In addition, 8 to 12 parts by weight of plantain extract extracted from plantain is further included with respect to 100 parts by weight of the mixture mixed with mulberry extract, lotus extract and ivy extract.

Plantain contains apigenin, ursolic acid, pretaginine, beta sitosterol and acubin. In particular, the ingredients contained in plantain has a wound regeneration effect, it was confirmed that there is a rapid regeneration of the trauma generated during the dense breeding process.

As described above, the feed additive may be added to the basic feed for eel, which is commercially supplied in powder form, or the extract produced by the distillation method may be added to the basic feed.

Preferably, the basic feed is composed of 49% by weight crude protein, 3% by weight crude fat, 2% by weight calcium, 2.7% by weight, 3% by weight crude fiber, 18% by weight ash, 22.3% by weight squid meat. .

The ratio of the feed additive to the basic feed is 2 to 5 parts by weight of the feed additive is added to 100 parts by weight of the basic feed when applied in the form of a powder.

In addition, when added as a feed additive in the extract liquid relative to the basic feed is added 0.01 to 0.2 parts by weight of the feed additive extract based on 100 parts by weight of the basic feed. The method of adding the feed additive extract to the basic feed is made by mixing the extract with the basic feed, kneading it, and then preparing the granulated form with 15% moisture by a molding machine, or spraying the extract while stirring the basic feed formed in the granular form. A method of injecting by spraying in a manner may be applied.

As a result of feeding the feed additives added to the eel and rearing it, it was confirmed that the wound of the eel, which may occur in the dense rearing process, was quickly healed and mortality was suppressed by the increase of immunity.

Thereafter, the third sample was fed to another 2000 eels fed into another tank under the same conditions as in Experimental Example 1, and then cultured for 100 weeks to prepare a third experimental group.

On the other hand, the comparison group was cultured using only the basic feed without using the feed additive according to the present invention. At this time, only the feed type for the eel was different, and the same conditions as the experimental group and the comparative group were applied to the size, water temperature, oxygen amount, direct sunlight shading, and breeding number of eel tanks.

As described above, after the first, second, and third experimental groups and the comparative group were cultured, the meat quality, mortality, and taste of consumers who tasted the eel cultures were tested.

(1) Quality Analysis

The following table | surface was obtained by analyzing the meat quality of the 1st, 2nd, 3rd experimental group and the comparative group obtained in the said Example 1, 2, 3. In meat analysis, eel was removed from the head, internal organs and bones, and pure muscle tissue was collected and analyzed. The analysis method was water analyzer, crude protein Kjeldahl nitrogen quantitative method (N6.25), crude fat Soxhlet extraction method.

Item Experimental group 1 2nd experimental group 3rd experimental group Comparison Water content 50.9% 50.6% 50.8% 51.1% Crude protein 17.2% 18.3% 17.4% 15.2% Crude fat 24.9% 25.1% 24.8% 25.4%

As can be seen from Table 1, the crude protein of the experimental groups is higher than that of the comparative group.

(2) Mortality due to eel breeding

The mortality rate was calculated by feeding the feed during the aquaculture period and recording the mortality and incidence of trauma in the aquaculture journal. The results are shown in Table 2 below.

Item Experimental group 1 2nd experimental group 3rd experimental group Comparison Mortality 0.7% 0.7% 0.5% 7.8%

As can be seen from Table 2 above, the mortality rate of the experimental groups was drastically reduced for the comparison group.

In addition, although not dead, as observed from the appearance, the comparative group was a lot of wound traces on the skin due to frequent wound development, while the experimental group was clean enough to have almost no trace of wound.

In addition, as a result of comparing the weight by extracting the same number of population of 100 individuals for the experimental group and the comparison group, it was confirmed that the weight of the experimental group was about 2.5% higher for the comparison group. This result is expected to be an appetite boosting effect by the ivy extract.

<3> Surveying taste of consumers

Fifty randomly harvested eel diets fed the cultured eel diet according to the present experiment were evaluated to have a solid meat and improved taste. In addition, the experimental group 2 and the experimental group 3 of the experimental group was evaluated that much less fishy occurrence. This reduction in fishy predicts the effect by tomato extract.
