Abstract

PURPOSE: Provided is a production method of an egg containing omega-3 fatty acid, thereby producing high nutrient eggs to contribute to health improvement. CONSTITUTION: The production method of egg containing omega-3 fatty acid is characterized by comprising the steps of: preparing a feed composition containing 0.2-0.7% of crickets, referred to total weight of a feed for a laying hen; and feeding a laying hen with the composition for 7-14 days.

Description

Production method of eggs containing omega-3 fatty acids {Production method of egg}

The present invention relates to a method for producing eggs containing omega-3 fatty acids, in particular by feeding the cricket-containing feed composition intensively to laying hens for a period of time to produce eggs containing large amounts of omega-3 fatty acids, It relates to a method of producing eggs containing omega-3 fatty acids that have high nutritional value and improve product quality to contribute to national health.

In general, it is reported that the incidence of heart disease among people of a country that consumes abundant fish or processed foods is lower than that of a country that does not consume fish. As a result of this investigation, the fish found that there are more essential fatty acids called omega-3 polyunsaturated fatty acids than other foods.

Omega-3 fatty acids are essential fatty acids that have a double bond to the third carbon from the end of the carbon side chain among unsaturated fatty acids. These essential fatty acids make up the tissue of the cell and promote the metabolism of the body as well as In addition to essential nutrients for growth and brain development, omega-3 fatty acids have been shown to have various effects on the prevention of cardiovascular diseases, anti-tumor effects, and prevention of learning ability by lowering cholesterol in the blood.

Therefore, due to the westernization of the diet, cardiovascular diseases including arteriosclerosis caused by eating meat are increasing as a cause of death in Korea due to the change from vegetarian to meat, and research on functional eggs is actively conducted to lower fat and cholesterol content. It is becoming.

However, in order to produce functional eggs, the meat quality of the broilers must first be improved, and the functional eggs must be produced through improved milking. Through this, the intended purpose, ie functional eggs could be produced, but when feeding the broiler's normal feed to the broiler, the content of fatty acids in the feed increased and the feed intake decreased. As a result of a decrease in the activity of the enzyme involved, weight gain was delayed, which caused various problems in that it was unable to produce functional eggs more effectively.

Therefore, the object of the present invention was devised in view of the above-described conventional problems, by intensively feeding feed compositions containing crickets to laying hens for a period of time to produce eggs containing large amounts of omega-3 fatty acids, It is to provide a method for producing eggs containing omega-3 fatty acids that have high nutritional value and improve product quality to contribute to national health.

As a means for achieving the above object, the present invention, after preparing a feed composition containing 0.2% to 07% of the cricket per total weight of a conventional laying hens feed, feed the feed composition to the laying hens 7 to 14 days The production of eggs containing omega-3 fatty acids is a fundamental feature of the technical configuration.

Hereinafter, preferred embodiments of the present invention will be described in detail.

First, the cricket and cricket feed composition used to obtain eggs containing omega-3 fatty acids are not only rich in omega-3 fatty acids, especially DHA, but also chitosan. It is abundant and is the only breed in the world as a food insect.

Therefore, crickets contain high fat (21.8% fat) and high protein (52.81% protein) components, contain large amounts of palmitic acid, oleic acid and linoleic acid, and essential ω-3 and ω-6 series essential unsaturated fatty acids. have.

These crickets are reared in large quantities in a breeding room, either mixed with a conventional feed in a live state, or rapidly frozen to prevent destruction of nutrients, and then dried and powdered in a freeze dryer at -40 ° C and mixed with a conventional laying hen. The content of crickets formulated in a conventional laying hen's feed consists of a feed composition containing at least 0.2-0.7% per total weight of the conventional laying hen's feed.

(Example)

Example 1

For 20 broiler chickens of 4 weeks of age, feed compositions containing 0.4 g of crickets (corresponding to about 2 crickets) per head were fed from 1 week before shipment.

Example 2

For 20 heads of three-week-old broilers, feed compositions containing 0.4 g of cricket per head were fed two weeks before shipment.

Comparative example

For 20 broilers, the conventional diet was fed for 5 weeks.

Test Example 1

While maintaining the indoor temperature 22 ℃, 60% humidity in a breeding ground of 1.2m horizontally and vertically, the experiment 1 and 2, and the comparative example was repeated four times to observe the feed intake and body weight, the results are shown in Table 1 It is described in.

(Unit: g / number) Feed week 3 Feed week 4 Feed week 5 Example 1 Feed intake 723 768 922 weight 423 857 1371 Example 2 Feed intake 694 758 896 weight 434 840 1343 Comparative example Feed intake 713 767 983 weight 429 910 1389

As can be seen in Table 1, in the case of Examples 1 and 2 feeding the feed composition containing the cricket of the present invention shows a similar intake and weight gain compared to the case of the comparative example of feeding a conventional feed, It can be seen that if the feed composition containing the cricket of the present invention is fed for one week or two weeks, it can have the productivity of a normal chicken level.

Test Example 2

The fatty acid composition in the carcasses of broilers of Example 2 and Comparative Example was measured, and the results are shown in Table 2 below.

Type of fatty acid Example 2 (%) Comparative example (%) C14: 0 0.42 0.61 C16: 0 24.87 25.53 C16: 1 n-7 7.54 6.64 C18: 0 4.89 6.68 C18: 1 n-9 45.59 45.74 C18: 2 n-6 ^** 14.90 13.31 C18: 3 n-6 ^** 0.13 0.13 C18: 3 n-3 ^* 0.72 0.65 C20: 1 n-9 0.14 0.08 C20: 2 n-6 ^** 0.00 0.00 C20: 3 n-6 ^** 0.06 0.05 C20: 4 n-6 ^** 0.53 0.43 C20: 5 n-3 ^* 0.09 0.04 C22: 4 n-6 ^** 0.13 0.11 C22: 5 n-3 ^* 0.00 0.00 C22: 6 n-3 ^* 0.00 0.00 Saturated fatty acid 30.18 32.82 Unsaturated fatty acid 69.82 67.18 -unit price 53.26 52.46 - 16.56 14.72

※ n-3 ^* stands for ω-3 and n-6 ^** stands for ω-6.

As can be seen in Table 2, the content of omega-3 fatty acids increased 1.1 to 2.3 times in Example 2 compared to the comparative example, the ratio of omega-6 fatty acids: omega-3 fatty acids was lowered Able to know. In addition, it can be seen that the polyunsaturated fatty acids increase and in particular, the ω-3 and ω-6 series of unsaturated fatty acids increase, which tends to improve meat quality.

Test Example 3

Fatty acids of eggs produced in the laying hens of Example 2 and Comparative Example were analyzed and the results are shown in Table 3.

Type of fatty acid Example 2 Comparative Example C _{14: 0} 0.37 0.50 C _{14: 1} 0.06 0.11 C _{15: 0} 0.08 0.09 C _{16: 0} 23.68 23.37 C _{16: 1} 3.05 4.04 C _{17: 0} 0.35 0.28 C _{17: 1} 0.35 0.34 C _{18: 0} 7.70 7.70 C _{18: 1} 47.49 46.77 C _{18: 2 n6} 11.79 12.08 C _{18: 3 n3} 0.51 0.46 C _{18: 4 n3} 0.24 0.32 C _{20: 0} 0.01 0.01 C _{20: 1} 0.25 0.30 C _{20: 3 n6} 0.10 0.07 C _{20: 4 n6} 1.91 1.87 C _{22: 4 n6} 0.22 0.17 C _{22: 5 n3} (DPA) 0.14 0.08 C _{22: 6n3} (DHA) 0.94 0.65 Unknown 0.76 0.79

As can be seen in Table 3, when the eggs produced in laying hens fed feed composition containing crickets, and the fatty acids contained in eggs of laying hens not fed feed composition, the amount in Example 2 was higher than in Comparative Example. It can be seen that the content of omega-3 fatty acids of the increase is particularly high.

As described above, according to the present invention, if the feed composition containing crickets is concentrated and fed to the laying hens for a certain period of time, it is possible to obtain a high quality egg as well as a nutritious value because it produces eggs containing a large amount of omega-3 fatty acids. Is much higher than ordinary eggs, which can contribute to national health.

The present invention has been described above with reference to specific preferred embodiments, but the present invention is not limited to the above embodiments and various changes and modifications may be made by those skilled in the art without departing from the gist of the present invention. Make sure you can.
