Description

Feed composition containing crickets {Feed-composite that include cricket}

The present invention relates to a feed composition containing crickets, and in particular, by lyophilizing a mass bred crickets, the powdered cricket raw material is mixed with a conventional feed at a predetermined ratio to prepare a feed composition, and then the feed composition is used for livestock or The present invention relates to a feed composition containing crickets, which is made by feeding farmed fish to improve meat quality so that the nutrition and flavor of meat is excellent.

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 westernization of the diet, cardiovascular diseases including atherosclerosis caused by eating meat are increasing as a cause of death in Korea due to the change from vegetarian-to-meat-based, and domestic animals with omega-3 fatty acids lowering fat and cholesterol content Or research on farmed fish is being actively conducted.

However, processed feed is essential for the breeding of livestock or farmed fish. As the fatty acid content of the feed increases, the feed for vegetable seeds should be extended over a long period of time. In addition, the increase in body weight was delayed due to a decrease in the activity of enzymes involved in body fat synthesis, and this naturally caused a great problem that meat quality was greatly reduced, nutrition was reduced, and taste was greatly reduced.

Therefore, the object of the present invention was devised in view of the above-described conventional problems, and after lyophilizing a large number of crickets, the powdered cricket raw material was mixed with a conventional feed at a predetermined ratio to prepare a feed composition, and It is to provide a feed composition containing crickets to improve the meat quality by feeding the feed composition to livestock or farmed fish.

As a means for achieving the above object, the present invention, after preparing a lyophilized powdered cricket at a temperature condition of minus 40 ℃ in a large-scale breeding biological cricket or frozen and lyophilizer, the cricket It is formulated into a feed composition by blending with a feed at a predetermined magnification, and the feed composition is characterized in that it contains at least 0.2% to 07% of the cricket per total weight.

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

(Example)

First of all, the cricket and cricket feed composition used to obtain chicken meat containing omega-3 fatty acids is a crustacean insect, 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 formulated in the phosphorus feed consists of a feed composition containing at least 0.2-0.7% per total weight of conventional feed.
