Description

Production method of broiler containing omega-3 fatty acid using cricket feed composition {Production method of the fowls}

The present invention relates to a broiler production method containing omega-3 fatty acids using a cricket feed composition, in particular feed composition containing a cricket to the broiler by varying the feeding time according to the use of broiler chicken in a high concentration in a short time The present invention relates to a broiler production method containing omega-3 fatty acids using a cricket feed composition to obtain chicken meat containing a large amount of omega-3 fatty acids.

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.

On the other hand, foods containing a high concentration of omega-3 fatty acids include eggs, pork, chicken, etc. Feed composition containing rapeseed seed, fish meal, flaxseed, linseed seed, perilla seed as mainly sources of omega-3 fatty acid Foods obtained by providing

Therefore, in recent years, due to the westernization of diet, cardiovascular diseases including atherosclerosis caused by eating meat are increasing in Korea due to the change from vegetarian to meat, and broilers with omega-3 fatty acids lowering fat and cholesterol content. In other words, research on chicken dishes is being actively conducted.

However, in the case of broilers, as the content of these fatty acids in the feed increases, feeding to the vegetable seeds should take place over a long period of time, resulting in a decrease in feed intake and a decrease in the activity of enzymes involved in body fat synthesis in the liver. There are various problems that delay weight gain.

The object of the present invention was devised in view of the above-mentioned problems, and selects crickets that contain a large amount of omega-3 fatty acids and are reared in large quantities, and the reared crickets are formulated in a conventional feed, and then broilers It is to provide a broiler production method containing omega-3 fatty acids using a cricket feed composition to obtain chicken meat containing omega-3 fatty acids by feeding to.

Another object of the present invention is to provide a large amount of omega-3 fatty acids in broilers by supplying a small amount of crickets in a short period of time by varying the feeding time of the feed composition containing crickets according to the intended use of broilers To provide a broiler production method containing omega-3 fatty acids using the cricket feed composition.

Another object of the present invention by feeding the cricket-containing feed composition to broiler chickens to prevent the delay of weight gain in broilers, as well as to obtain a nutritious and flavorful chicken meat omega- It is to provide a broiler production method containing three series fatty acids.

As a means for achieving the above object, the present invention provides a feed composition containing at least 0.2% to 0.7% of the cricket per conventional gross weight, and then the feed composition is differently fed according to the intended use of broilers. However, before the broiler chicken is shipped from 7 to 14 days before, if used for Samgyetang, from 10 days to 17 days after the chick stock, if used for general use from 21 days to 28 days after the chick stock intensive omega in a short time It is the technical feature that it is characterized by making -3 type | system | group fatty acid be contained in broiler chickens.

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

First of all, crickets and cricket feed compositions used to obtain chicken meat containing omega-3 fatty acids are not only rich in omega-3 fatty acids, especially DHA, but also rich in chitosan. It is the breed which is kept only as a food insect in the world.

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 nutrient destruction, and then dried and powdered at -40 ° C in a freeze-dryer and blended with a conventional feed. The content of crickets incorporated into the phosphorus feed consists of a feed composition containing 0.2 to 0.7% per total weight of conventional feed.

The feed composition was able to obtain a chicken containing omega-3 fatty acids in a short time by feeding to the milk system differently depending on the use of broilers.

For example, feed composition to broilers from 7 to 14 days before chickens are released, and feed composition to broilers from 10 to 17 days after chicks are used when used for samgyetang. Feeding broiler chickens from 21 to 28 days after stocking yields the appropriate omega-3 fatty acids.

In particular, from 10 or 11 days before the feed composition containing crickets, from 13 or 14 days after chicks are used for samgyetang, from 24 or 25 days after chicks are used for general use. When fed, they were able to obtain chicken meat containing the optimal omega-3 fatty acids.

(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.
