Description

Feed additive composition for pets containing black soldier fly {Feed additive composition for pet containing ptecticus tenebrifer}

The present invention relates to a feed additive composition for companion animals that has an immunity-enhancing effect, containing as an active ingredient the powder of black soldier fly larvae, dried and ground, and the mixture of the present invention has an excellent effect in improving the immunity of companion animals. In addition, it has the effect of improving skin diseases, so it can be very useful as a functional pet feed additive.

Although companion animals grow up protected as members of the family, they are frequently exposed to polluted natural environments such as air and water pollution, processed foods, and stress that humans experience. For this reason, companion animals are also suffering from various diseases that commonly occur in humans, such as skin diseases, respiratory diseases, and digestive disorders. In addition, since dogs live indoors, they have little exercise, which increases the risk of obesity and secondary diseases. Therefore, medicines and feed made with natural products exclusively for pets can help them live healthy lives by increasing their immunity. Material discovery is a very important task. According to the Korea Rural Economic Institute in October 2018, the size of the domestic pet food market was KRW 889 billion, and the industry estimates that it will approach KRW 1 trillion this year.

Pet food refers to food for companion animals. The most common ones are cat food and dog food, and are also called specialty feed (special purpose products). It refers to special-purpose feed that is manufactured using a special method in a separate production facility that is different from the manufacture of general livestock compound feed. It is manufactured by adding special-purpose feed ingredients such as colorants, anticoagulants, binders, flavoring agents, and antioxidants.

Black soldier flies are insects of the arthropod insect class Diptera and black soldier flies, which have black bodies and live in dirty water or manure piles. These black soldier flies are mainly distributed in Korea and Japan, but the American black soldier flies are widely distributed worldwide and are common in Australia in the southern hemisphere, the northern hemisphere, and the southern United States. In addition, 14 species are described in the black soldier fly family in Korea. In particular, the body length of adult black soldier fly larvae is approximately 20 mm, and the body length of adults is approximately 13 to 20 mm. Additionally, larvae are brown overall and adults are black.

Unlike common Diptera pests, these black soldier flies have a unique adult mouthpart and do not regurgitate after feeding, so they do not cause disease and do not cause direct harm to humans. Although distributed worldwide, it is not classified as a sanitary pest, does not invade human residential areas, and lives in livestock farms, food waste dumps, and compost sites with a lot of organic matter. It is known that adult insects do not feed.

There are methods for collecting and selecting black soldier flies such as larvae, pupae, adults, and egg masses. Larvae and pupae can be collected from pig manure yards and livestock manure yards, which are the habitats of black soldier flies, between July and August. Larvae that are developing by feeding on livestock manure and pupae that move from wet places and gather in dry places can be collected. To collect adult insects, traps are set up in the habitat where the adult insects can be attracted, and then the flying stratum is collected using an insect net. Therefore, in order to collect adult black soldier flies using conventional techniques, the collector must personally collect adult black flies in flight, so the amount of black soldier flies collected could not be large. Meanwhile, black soldier fly larvae are also provided as feed for various livestock (cattle, pigs, chickens, etc.) and farmed fish, so the range of use for black soldier flies is expanding.
