Description

{PRODUCTION METHOD OF HIGH WEIGHT EGG USING FEEDSTUFF COMPRISING PERSIMMON PEEL FOR LAYING HENS AND EGGS PRODUCTED FORM THE HENS BEING FED WITH THIS FEEDSTUFF}

The present invention relates to a method for obtaining from a laying hen a heavy egg with an egg white portion and an egg shell portion developed by feeding a laying hen feed containing dry pulverized persimmon shell, and an egg produced thereby.

Persimmon trees are mainly produced in temperate Asia, Korea, China, and Japan, and can be cultivated anywhere in Korea, and are classified into sweet persimmons and red persimmons depending on the variety.Korea's native varieties are red persimmons, and red persimmons retain 1 to 2% of tannin even after maturation. As it contains, it was prepared as dried persimmon or new year after harvesting and edible.

Persimmon is an alkaline food rich in sugars such as glucose and fructose, vitamins A, C, and beta-carotene. It promotes contraction and secretion of the intestine, and has the effect of stopping bleeding and coughing. When ingested, it has the effect of increasing immunity and improving digestive function. Show.

On the other hand, as described above, due to the tannin (water-soluble) component contained in the red persimmon, it is difficult to ingest it as it is, and it is processed as dried persimmon or yeonshi to be consumed.In the manufacture of dried persimmon, the dried persimmon is prepared after peeling off the peel of the red persimmon. , Persimmon peel is discharged as a by-product.

In the case of Sangju, Gyeongsangbuk-do, which accounts for 60% of the nation's total production of dried persimmons, about 4,000 tons of persimmon by-products are generated annually.

Here, if you look at the ingredients of the astringent persimmon skin, the composition of the astringent persimmon skin is about 21.4% of moisture, 7.3% of crude protein, 2.1% of crude fat, 2.3% of crude fat, carbohydrates account for 66.9%, and water-soluble tannins are about 102.4. It is known to be mg/100g.

The sugar component is about 15 to 16% and mainly contains half of fructose and glucose. Total amino acids are 4.8g/100g, of which free amino acids are about 0.7g/100g.

Major amino acids include glutamic acid, proline, methionine, and aspartic acid, and proline is known to be the most free amino acid.

In addition, many major fatty acids include oleic acid, linoleic acid, and palmitic acid. In particular, unsaturated fatty acids are known to account for 72.8% of the total fatty acids, and the persimmon peel contains more vitamins A and C than persimmon flesh.

On the other hand, in the case of poultry farms equipped with automated facilities, as a result of investigating the blue rate at which produced eggs break during automated processes such as transport, washing, and packaging, it was found to be about 1 to 1.5% (according to the survey report, up to 7% Also reported), and the main cause of blueness was analyzed by the inexperienced development of egg shells (reported paper by the Poultry Products Research Committee / The effect of addition of Cheonnyeoncho extract and dietary sulfur on the productivity, quality, and sensory properties of eggs. Influence, etc.), the egg shell development of eggs is studied to be influenced by calcium intake of laying hens, and in addition to vitamin C and D and phosphorus intake.

As described above, persimmon shells are very good in ingredients so that they are used for food, and there are many advantages when used as feed additives. In fact, when persimmon shell is fed, it is known to be helpful in promoting growth, preventing and treating diseases, and preventing diarrhea, and Korean Patent Publication No. 10-2002-0040960 discloses a technology in which persimmon shell is used in feed for ruminants. have.

On the other hand, in recent years, various studies on “high-quality poultry products production technology research” have been conducted to improve the quality of eggs, and various functional eggs are provided by feeding fish and shellfish skins, legumes skins, herbal by-products, omega fatty acids, wood acetic acid, and pine by-products. A technology for producing is being developed and provided, and as an example, Korean Patent Registration No. 10-1401194 discloses a technology for a method of producing an egg with reduced cholesterol by feeding feed containing oyster shells.

Hereinafter, with reference to the accompanying drawings, a laying hen feed including persimmon skin according to a specific embodiment of the present invention and eggs produced from the laying hen fed the same will be described in detail.

Prior to the description, the effects, features, and methods of achieving them of the present invention will be clarified in the embodiments described later in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in a variety of different forms, only the present embodiments are intended to complete the disclosure of the present invention, and the general knowledge in the technical field to which the present invention pertains. It is provided to completely inform the scope of the invention to those who have it, and the invention is only defined by the scope of the claims.

In describing embodiments of the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted, and terms to be described later are in the embodiment of the present invention. These terms are defined in consideration of the function of the user and may vary according to the intention or custom of users or operators. Therefore, the definition should be made based on the contents throughout this specification.

Laying hen feed containing persimmon skin according to the present invention is basically, as shown in FIG. 1, pulverized dried persimmon skin and then frozen and stored persimmon additive powdered into 20 mesh particles according to the growth stage of the laying hen. It is produced by mixing with injection.

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

For the performance test of eggs produced from laying hens fed laying hens feed containing persimmon shell, 25 eggs are collected per treatment every one week after the start of the test, and egg shell strength, egg shell weight, egg shell thickness, and egg yolk height. , Egg yellow color and heavy rain unit values were analyzed and tested.

To test the nutrient and protein content of eggs, add 10 ml of 6N-HCl to 0.1 g of egg yolk, react at 110 C for 24 hours, and then filter.After filtering, remove chliride gas and add 25 ml of sodium citrate buffer (pH 2.2). It was added, filtered with 0.2 μm, and analyzed using an amino acid analyzer.

After putting the lipid separated from the yolk into the test tube, add 1 ml of 4% BF3 solution, close the lid, heat at 90 C for 10 minutes, cool at room temperature, cool, add 2 ml of distilled water, shake, add 3 ml of hexane, shake, and shake the lower layer. After removal, 8 ml of distilled water was added and shaken. After removing the lower layer, Na2SO4 was added to remove moisture, and 2.5~3ul of the supernatant was taken and injected into gas chromatography to separate and quantitatively analyze fatty acids.

The immunity (disease resistance) test of laying hens compared and analyzed the mortality rate and disease incidence rate of chickens after test breeding, and after the end of the test, 10 animals were randomly selected for each treatment group to confirm the composition of immune cells and biochemical composition after blood collection.

1. Manufacturing method of gamskin additives (freeze drying).

The skin additives according to the present invention are prepared by a freeze (freeze) drying method.

The freeze-drying method is a drying method in which an object to be dried is cooled to a low temperature to freeze, and the moisture contained in the object to be dried is sublimated to remove moisture, and is a method used in the manufacture of instant food.

In the second embodiment of the present invention, first, the collected persimmon shell is cooled to a temperature of -15°C to -30°C to make it in a frozen state.

Thereafter, the cooled persimmon shell is put into a decompression device, and the ice contained in the persimmon shell is sublimated through decompression to convert it into a gaseous state.

The freeze-drying process is completed after the air in the decompression device containing the vaporized moisture is ventilated to remove it.

At this time, the moisture content of the freeze-dried persimmon shell varies depending on the freezing temperature and the degree of decompression, but is generally maintained at less than 5%.

In the case of drying the persimmon skin by freeze drying as described above, there is a disadvantage of slightly increasing the production cost due to drying, but in case of mass production, not only the economy is similarly increased to that of hot air drying, but also amino acids and vitamin C in the persimmon shell are effective. There is an effect that the active ingredients of the persimmon shell can be utilized without loss by preventing the ingredients from being destroyed by heating.

Next, the freeze-dried persimmon shell is pulverized to a particle size of 20 to 30 mesh according to the growth stage of the laying hen to complete the persimmon additive.

In this case, when the freeze-dried persimmon shell is pulverized through a grinder, moisture in the atmosphere may be absorbed and the moisture content of the persimmon shell may slightly increase in the process of increasing the temperature due to exposure of the persimmon shell to room temperature. In particular, the increase in moisture content may vary depending on the grinding environment (weather conditions, rain, etc.).

In order to prevent this, in the present invention, the crushing process may be performed by mixing lime in the crushing process of the freeze-dried persimmon shell.

That is, the lime is included in the laying system injection material to aid in intake and decomposition of calcium by the laying hen, and it plays the role of a desiccant during the pulverization process of persimmon skin to prevent the moisture content of persimmon skin from increasing.

At this time, lime in powder form may be used, and lime in lump form may be added to be crushed together with persimmon skin.

Here, the ratio of the lime to be added may vary depending on the amount of lime contained in the injection material, and it is preferable that the total amount of lime contained in the gamma additive and the total amount of lime contained in the injection material be 3% by weight or less of the total laying hen feed. .

That is, in general, considering the fact that the lime content in the injection material is about 2 to 3%, and the content in the injection material of the sensitization additive is less than 5%, the lime content in the sensational additive should be added to less than 60% by weight of the sensitization additive, It is preferably added in an amount of 30 to 40% by weight.

The skinning composition produced by lyophilization as described above does not have a heating process, so it is dried without change in active ingredients such as crude protein, amino acids (especially free amino acids), and vitamins in the persimmon skin, and the moisture content is 3% to 5%. It is low, and there is an effect that the shelf life of the feed can be set for a long time due to low risk of harmful bacteria proliferating in the feed even when stored at room temperature for a long time when mixed with injections.

Accordingly, the reduction of skin additives produced by freeze-drying may slightly increase the production cost, but there is an effect of securing excellent efficacy of the produced feed.

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

2. Mixing with injection

Next, the injection material to be mixed with the dried/crushed persimmon additive is produced in various compositions, and the composition changes depending on the growth stage of the chicken.

Specifically, in the case of laying hens, broiler feeds are used as injections from chicks until early spawning, and feeds for laying hens having different compositions depending on the initial, middle, and end of spawning are used.

Here, the injection material is basically composed of a mixture of grains, watermelons, animal fats, grain by-products, and minerals including lime, and as shown in FIG. 2, the crude protein component in the laying hen feed is less than that of the general meat feed. Instead, it can be seen that the crude powder and calcium content are high.

That is, it can be seen that 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 skin-reducing additive as described above is 4 to 6% by weight in consideration of the test results and economic feasibility to be described later.

3. Test result

As a result of testing by feeding laying hens with the feed for laying hens produced as described above, the following effects were verified for the growth of laying hens and eggs obtained from laying hens.

(1) Results of observation of growth of laying hens

As a result of observing the growth of laying hens (test group) fed with the feed mixed with the persimmon additives according to the present invention and the laying hens fed with general injection (control), as shown in FIG. Microscopically, the growth of the control group was faster at the early weeks of age, but after 5 weeks, the group with 5% persimmon peel showed microscopically rapid growth.

(2) Egg production and feed intake (feed demand rate)

As a result of measuring the amount of feed consumed for one day (24 hours) per week based on unlimited feeding (feed 150g per animal and check the remaining amount after 24 hours to check the total intake), as shown in FIG. , Initially, the feed intake rate of the test group decreased, but the intake rate recovered 4 weeks after intake. From then on, the intake of persimmon skin added feed showed an increasing trend.

It is estimated that the intake rate of laying hens decreases due to the astringent taste due to the tannin component of the persimmon shell, but the intake rate increases as the adaptation and digestibility increases.

Accordingly, the feed containing persimmon shell is judged to be unsuitable for broilers with a short growth period, and can be determined to be suitable for laying hens with a long growth period.

(3) Scattering efficiency test

As a result of comparing each group by checking the spawning rate for each group, as shown in FIG. 5, in the case of 5-10 weeks after eating persimmon skin feed, the spawning rate of the persimmon intake group was lower than that of the control group, but this is the effect of the feed intake rate. The feed intake rate increased compared to the control group after adaptation to persimmon skin.

(4) Disease resistance test (comparison of survival rate by group)

The mortality rate during the test period in the experimental group was 0%.

To confirm disease resistance, blood was collected from 10 chickens in each group 5 weeks after consumption of persimmon skin feed, and the result of confirmation of the composition of immune cells in the blood, compared to the control group in the chickens in the test group, white blood cells, lymphocytes, macrophages, and B. Antibodies such as cells were improved, and as a result of analysis using the ELISA Kit, the chickens in the test group were analyzed to have higher protein content than the control group.

(5) Comparative investigation of raw materials and nutrients of persimmon peel

As a result of conducting an examination for each component after drying the basic nutrient ingredients of the gamma additive and the injection material according to the present invention in a dry-oven for 6 hours, as shown in FIG. 6, the gamma additive was found to contain a large amount of fiber insufficient in the injection material. It was confirmed, and although not described in the table, it was confirmed that the gamma additive was excellent in the content of amino acids.

On the other hand, the persimmon peel used in the persimmon skin additive according to the present invention basically uses the skin of the red persimmon that comes out as a by-product when processing the red persimmon into dried persimmon, but various parts of the red persimmon may be used depending on economy. In other words, when the amount of red-marking is large and the red-marked meat is disposed of, it is also possible to use the red-marked pulp.

(6) egg sensory test

As a result of sensory testing of the eggs produced by the test group and the control group according to the present invention, as shown in FIG. 7, the weight of the eggs produced by the 5% persimmon shell added group was the heaviest, as shown in FIG. Was analyzed.

In addition, as shown in Figs. 8 and 9, as a result of observing the yolk and egg white for the contents of the eggs for each group, there is no difference in the size of the egg yolk, but it was found that the eggs of the test group showed the barking color in color. , It was analyzed that the eggs of the test group showed a rather large tendency in the size of the egg white part.

On the other hand, although the egg shell thickness of the test group and the control group were directly measured, reliable results could not be derived due to the error range of the measuring instrument (vernier caliper). However, it was detected through the difference in weight and the weight of egg contents. It was analyzed that the thickness of the egg shell was further developed in the experimental group to which the gampi additive was administered.

4. Another embodiment of the present invention

On the other hand, the feed according to the present invention containing the freeze-dried persimmon skin as described above is rich in active ingredients such as crude fiber and amino acid vitamins, and the egg-white portion of the egg obtained therefrom is of course improved growth of the laying hens fed them. This is particularly developed and has the effect of obtaining a heavy egg.

However, looking at the test results by feeding the feed containing persimmon skin to the laying hens, however, when feeding the feed containing persimmon additives to the laying hen, the feed consumption rate of the laying hens decreases at the beginning of feeding (see Fig. 4), It can be seen that the feeding rate is similar to that of the general conventional feed after about 4 weeks have passed.

In addition, as a result of testing the eggs produced during this period, the overall weight of the eggs decreased, and the reason for this was that the sensory test results of the eggs obtained during these periods confirmed that there is no effect of developing the egg white portion, the advantage of the eggs according to the present invention. Became.

Accordingly, in the present invention, it is determined that the decrease in the feed consumption rate of the laying hens that occurs at the beginning of feeding the feed containing the persimmon skin additive is due to the peculiar bitter taste of the tannin contained in the persimmon skin, and the desorption process in the freezing process of the persimmon skin additive according to the present invention It provides an embodiment that is achieved together.

That is, another embodiment of the present invention is to perform the desorption freezing process, and the same freeze-drying process as described above is performed, but dry ice is added together with persimmons to the decompression device.

In this case, the persimmon shell is cooled by dry ice, and as the pressure in the pressure reducing device increases, moisture in the persimmon shell evaporates and carbon dioxide is vaporized from the dry ice.

On the other hand, in the case of another embodiment of the present invention, after the ventilation process of discharging the water vapor in the decompression device to the outside, the dry ice further comprises a maintenance step of maintaining the water vapor in the decompression device for a predetermined period of time. do.

During the freeze-drying process, the persimmon shell is exposed to a high concentration of carbon dioxide, and accordingly, the water-soluble tannin in the persimmon shell is changed to insoluble tannin, thereby removing the astringent taste peculiar to the persimmon shell.

In other words, the persimmon additives that have undergone the above-described de-insertion results have their characteristic astringent taste removed, and the feed for laying hens including this can maintain a high feeding rate even at the beginning of feeding, and accordingly, the egg white part of eggs produced at the beginning of feeding It is greatly developed and has the effect of producing high-weight eggs.

On the other hand, in the present invention, it is also possible to add sodium chloride together when dry ice is added to the pressure reducing device. The sodium chloride promotes the desorption process of converting water-soluble tannins into insoluble tannins, and when included in feed and provided to laying hens, it affects the thickness of the egg shells of the produced eggs, thereby producing a strong egg shell.

At this time, the amount of sodium chloride added is preferably about 0.3 to 0.44% by weight of the total feed, considering that the sensitized additives account for 4 to 6% by weight of the total feed, and considering the amount of loss in the pulverization and mixing process, the sodium chloride It is preferable that 5 to 15% by weight is added with respect to the sensitized additive.

That is, in the present invention, the use of sodium chloride to thicken the egg shell thickness of the production eggs can be expected to have a double effect of increasing the desorption efficiency of the skin additives.

Figures 10 and 11 show eggs produced from laying hens fed with feed for laying hens containing persimmon additives that have undergone a non-removal freeze-drying process, and from laying hens fed with feed for laying hens containing persimmons additives that have undergone a descaling freeze-drying process. The results of testing against produced eggs are shown.

As shown in Fig. 10, as a result of comparing the weight of the eggs, when feeding the feed that has undergone non-desorbing freeze-drying process, a temporary weight reduction phenomenon appears in eggs produced at the beginning of feeding (about 1 to 3 weeks). I can confirm.

This is, as shown in Fig. 11, as a result of observation and investigation of the egg yolk and egg white of the eggs for each of these weeks, in the case of eggs produced through feeding the feed that has undergone a non-destructive freeze-drying process, the initial feeding (about 1 to 3 weeks ), while the egg white part of the egg produced in) was relatively less developed, the egg produced through feeding the feed that had undergone a de-insertion freeze-drying process showed a relatively constant amount of egg white regardless of the feeding timing.

Accordingly, in the case of another embodiment of the present invention, there is an effect of obtaining a heavy egg with an egg white portion developed throughout the spawning period.

Of course, the underdevelopment of the egg white portion is a temporary phenomenon of about 1 month out of the total spawning period (about 16 months) of the laying hen, and the application of the desorption freeze-drying in the present invention takes into account the cost of the facility and the production cost. Can be applied selectively.

5. Feeding method

Feeding of laying hens is classified according to the growing age, and it is largely divided into the growing period (before spawning) and the spawning period.

The growing period is a period of about 20 to 25 weeks from chicks, and refers to a period in which the laying hen grows before starting spawning.

In the growing season, the feed for broilers is also fed to laying hens, and the feed for broilers is characterized in that the content of animal protein and fat is higher than that for injections for laying hens.

On the other hand, the feed feeding amount of laying hens in the growing season starts from 10g per day and increases the feeding amount sequentially, and reaches 80-90g per day at the end of the growing season.

Next, in the spawning period, a gamma additive is mixed and fed with an injection material for laying hens, and the content ratio of the gamma additive is determined to be 4 to 6% by weight as described above.

At this time, the amount of feed to be fed during the spawning period is 90 to 130 g/day, preferably provided by dividing it in two.

On the other hand, the spawning period is approximately 18 to 24 months, and it is divided into the early, mid, and late spawning periods in 6 to 8 months increments, and there is no significant difference in the feeding amount of the feed, but the reduction skin additive according to the present invention Mix and feed.

The rights of the present invention are not limited to the embodiments described above, but are defined by what is described in the claims, and that a person having ordinary knowledge in the field of the present invention can make various modifications and adaptations within the scope of the rights described in the claims. It is self-evident.
