Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. , Which may vary depending on the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

As shown in FIG. 1, the dry crust feedstuffs containing the crustacean according to the present invention are prepared by crushing dried persimmon crust and pulverizing the crushed 20-mesh crumbs to freeze-store the freeze-dried food additives according to the growth stages of the laying hens It is produced by mixing with the injection.

At this time, the amount of the additive to be added is 0.5 to 5% by weight.

For the performance test of eggs produced from laying hens fed diets containing persimmon shells, eggs were collected for 25 treatments per 1 week interval after initiation of the test to determine egg shell strength, egg weight, egg shell thickness, egg yolk height , I was tested by analyzing yellow and rainfall unit values.

For the nutritional and protein components of eggs, 10 ml of 6N-HCl was added to 0.1 g of egg yolk and reacted at 110 ° C for 24 hours. After filtration, 25 ml of sodium citrate buffer (pH 2.2) After the addition, the solution was filtered with 0.2um and analyzed using an amino acid analyzer.

After adding 1 ml of 4% BF3 solution to the test tube, the lid was closed and heated at 90 ° C for 10 minutes, cooled at room temperature, cooled, added with 2 ml of distilled water, shaken, 3 ml of hexane was added again, After removal of the lower layer, Na2SO4 was added to remove the water. 2.5 ~ 3ul of the supernatant was taken into the gas chromatograph and the fatty acid was separated and quantitatively analyzed.

Immunity (disease resistance) test of laying hens was compared and analyzed for mortality and incidence of chicken after the test. After the test, 10 rats were randomly selected for the treatment and immunocytochemical composition and biochemical composition were obtained after blood sampling.

1. Manufacturing method of a damping additive

Example 1 (hot air drying).

The moisturizing additive according to the present invention is prepared by evaporating the moisture of the peel shell, drying it, pulverizing it into 20 to 30 mesh particles, and storing it in a frozen state to prevent decay and fermentation.

At this time, in the drying method, the hot air drying method is applied to the first embodiment of the present invention. In the hot-air drying method, the collected persimmon shells are dried by hot air at 40 ° C to 50 ° C, and the persimmon shells are stirred in a rotary drum so that hot winds are uniformly distributed throughout the persimmon shells, desirable.

Thus, drying of the crust is intended to prevent water from being removed from the crust and prevent the harmful bacteria in the feed from multiplying or the feed being fermented when it is added to the feed.

At this time, if the temperature of the hot air is high, the drying efficiency is increased, but the amino acid and vitamin C components in the crust can be destroyed, and the efficacy of persimmon shells can be lowered.

Therefore, in the case of hot-air drying, it is preferable that the temperature of the hot air is maintained at less than 50 ° C, and it is preferable that the concentration of hot air is prevented from concentrating on the gum husk at a specific position.

On the other hand, the hot-air dried persimmon crust is pulverized to a particle size of 20 to 30 mesh, wherein the size of the pulverized particle size is preferably changed depending on the growth stage of the laying hens to be fed.

In other words, early laying hens use relatively crushed crusts with small particle size as an additive, and as the growth stage increases, the crumb grain size also increases to produce the additive.

On the other hand, the hot-air-dried pulverized pulp additive has a water content of about 10%, which can completely eliminate the possibility that harmful bacteria may grow due to the protein components contained in moisture, sugar, There is no. Therefore, it is not desirable to set the shelf-life of the egg yolk for the laying hens containing the produced additive to an excessively long period.

Example 2 (lyophilization).

Meanwhile, the humectant additives according to the present invention can be prepared by a freeze (freeze) drying method.

The lyophilization method is a drying method in which an object to be dried is cooled and cooled at a low temperature, and the moisture contained in the object to be dried is sublimated to remove moisture, which is a method used in instance food production.

In the second embodiment of the present invention, the collected persimmon shells are first cooled to a temperature of -15 캜 to -30 캜 to be frozen.

Thereafter, the cooled persimmon shells are put into a decompression apparatus, and the reduced ice is sublimated into a gaseous state.

After the air in the decompression apparatus containing the vaporized moisture is ventilated, the freeze-drying process is completed.

At this time, the water content of the lyophilized persimmon shells varies depending on the freezing temperature and decompression degree, but is generally maintained at less than 5%.

In case of drying the persimmon crust according to the freeze-drying method, there is a disadvantage that the production cost due to the drying is somewhat increased. However, when mass-produced, economical efficiency is similarly increased in the hot-air drying, and the amino acid and vitamin C in the persimmon shell are effective It is possible to prevent the components from being destroyed by heating and to utilize the effective ingredients of the persimmon shell without loss.

Next, the lyophilized persimmon shells are pulverized with a particle size of 20 to 30 mesh according to the growth stage of the laying hens, thereby completing a damping additive.

In this case, when the freeze-dried persimmon crush is crushed through a crusher, the moisture content of the shell shell may be slightly increased due to absorption of moisture in the atmosphere during the temperature rise of the persimmon crust exposed to normal temperature. In particular, the amount of increase in water content may vary depending on the crushing environment (weather conditions, rainy weather, etc.).

In order to prevent this, in the present invention, lime can be mixed and pulverized during the freeze-dried crust of crust.

That is, the lime is included in the layering liquid to help calcium ingestion and decomposition of the laying hens, and acts as a hygroscopic agent in crushing the persimmon crust to prevent the moisture content of the persimmon crust from increasing.

At this time, the lime can be a powdery lime, and a lumpy lime can be injected to be pulverized together with the persimmon shell.

Here, the input rate of the lime may vary depending on the amount of lime contained in the injection, and it is preferable that the total amount of lime contained in the additive and the total amount of lime contained in the injection are 3 wt% or less of the total amount of the feed .

That is, in consideration of the fact that the content of lime in the dyestuff is generally about 2 to 3% and the content of the dyestuff additive in the dyestuff is less than 5%, the lime content in the dyestuff additive should be less than 60% by weight of the dyestuff additive, And preferably 30 to 40% by weight.

As described above, the dampening composition produced by freeze-drying has no heating process and is dried without any change in active ingredients such as crude protein, amino acid (especially free amino acid) and vitamin in the crust and has a moisture content of 3% to 5% It is less likely that the harmful microorganisms will grow in the feed even when stored at a room temperature for a long period of time when the feed is mixed with the feed, so that the distribution period of the feed can be set long.

Thus, although the increase in the production cost may be somewhat incurred in the case of the dry matter produced by the freeze-drying, excellent efficacy of the produced feed can be ensured.

Of course, in the hot-air drying method as described above, it is also possible to prevent the moisture content of the composition from slightly increasing in the pulverizing process by mixing the lime in the pulverization process.

2. Mix with injection

Next, the injections to be mixed with the dried / pulverized edible additives are produced in various compositions, largely varying in composition depending on the growth stage of the chicken.

Specifically, in the case of laying hens, broiler feed is used as a feed for chicks until the initial egg laying, and feeds for laying hens having different compositions according to the early stage, middle stage and late stage of egg laying are used.

As shown in FIG. 2, as shown in FIG. 2, crude protein content of the feed for laying hens is smaller than that of a typical edible feed, as shown in FIG. 2, Instead, it is found that the calcium content is high.

That is, the composition of lime in the feed for laying hens is large.

On the other hand, it is preferable that the content ratio of the above-mentioned additive is 4 to 6% by weight, considering the test results to be described later and economy.

3. Test results

As a result of the feeding of the feed for the laying hens produced as described above to the laying hens, the following effects were proved on the eggs obtained from the laying hens and laying hens.

(1) Results of growth of laying hens

As a result of observing the growth of the laying hens (test group) fed with the mixed food according to the present invention and the laying hens fed with the common dough (control group), as shown in FIG. 3, The growth of the control group was accelerated at the early age, but after 5 weeks, the 5% addition of persimmon showed a fine growth.

(2) Egg Production and Feed Intake (Feeding Rate)

As shown in FIG. 4, the amount of feed consumed per day (24 hours) on the basis of infinite pay was measured (the amount of feed was 150 g per marriage and the remaining amount was confirmed after 24 hours) In the early days, the feed intake rate of the test group was lowered, but the intake rate was recovered 4 weeks after ingestion. From then on, the intake of persimmon added diets tended to increase.

This suggests that the intake rate of the laying hens is lowered due to the tannin content of the early enamel shells, but the adaptation rate and the digestibility are increased.

Therefore, it is considered that feed containing persimmon husk is not suitable for broiler chickens with shorter growth period and can be judged to be suitable for laying hens.

(3) Scattering efficiency test

As shown in FIG. 5, in the case of 5-10 weeks after the consumption of persimmon fodder, the rate of egg production in the persimmon peel group was lower than that of the control group, And the feed intake rate increased from the control group after the adaptation to the husk.

(4) Disease resistance test

Comparison of survival rates by group. To date, the mortality rate in the experimental group is 0%. In order to confirm the disease resistance, after 5 weeks from the consumption of persimmon peel, blood samples were taken from 10 chickens of each group, and the composition of immune cells in the blood was examined. As a result, the number of leukocytes, lymphocytes, macrophages and B Antibodies were improved in the cells and analyzed by ELISA kit. Chicken in the test group was analyzed to have higher protein content than the control group.

(5) Comparison of raw materials and nutrients of persimmon peel

As shown in FIG. 6, when the basic nutrients of the present invention were dried for 6 hours in dry-oven and examined for each ingredient, the amount of the deficient additive contained a large amount of fibers insufficient for the injection , And although not listed in the table, it was confirmed that the content of amino acid was superior to the amount of the detergent additive.

(5) Sensory evaluation of eggs

As shown in FIG. 7, when the eggs produced by the test group and the control group according to the present invention were subjected to a sensory test, the weight of the eggs produced by the group containing 5% persimmon peel was the heaviest Respectively.

In addition, as shown in Figs. 8 and 9, egg yolk and egg white were observed for the contents of eggs of each group. As a result, it was found that the egg yolk color of the test group showed the color of bark , Egg size of the test group was slightly larger than that of egg white.

It is to be understood that the invention is not limited to the disclosed embodiment, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.

The present invention relates to a egg yolk obtained from a dry crushed ground skin containing a crustacean and a fertilized egg laying hens. According to the present invention, an effective ingredient such as crustacean crude fiber and amino acid vitamin is provided to a laying hens, It has the effect of improving the growth, disease resistance and susceptibility to disease and obtaining high quality eggs.
