METHOD FOR PRODUCING FEED FOR RAISING CICADA LARVA USING OYSTER MUSHROOM MYCELIUM EXTRACT PRODUCED IN OAK SAWDUST CULTURE MEDIUM CONTAINING COTTONSEEDS, RICE BRAN, BEET PULP, AND SULFUR
The present invention relates to a feed for raising cicada larva using an oyster mushroom mycelium extract produced in an oak sawdust culture medium containing cottonseeds, rice bran, beet pulp, and sulfur, and a production method thereof. An oyster mushroom fruit body is produced by culturing a mycelium by inoculating a sawdust culture medium with an oyster mushroom mycelium cultured in a culture medium provided by mixing 65 wt% of oak sawdust, 12 wt% of cottonseeds, 11 wt% of beet pulp, 12 wt% of rice bran, and 2 wt% of sulfur and by combining and kneading the mixture with water. A mycelium powder is produced with oyster mushroom, sulfur, and sawdust through pulverization to a particle size of 100 mesh by using a pulverizing device after culturing a fruit body of a mycelium in a solid bottle culture medium at 25°；C for 30 days and by drying the same to have a moisture content of 4-5%. A sulfur liquid fertilizer is mixed with the mycelium powder, and hot water extraction is performed to obtain a filtrate. 90-95% of moisture of the filtrate is removed through a decompressed dryer, and a semi-solid concentrate is obtained and is freeze-dried. Accordingly, provided are an oyster mushroom mycelium produced in an oak sawdust culture medium, a feed additive for raising cicada larva comprising an extract thereof, and cicada larva fed therewith. An oyster mushroom mycelium powder or a hot water extract thereof including a culture medium cultured in an oak sawdust culture medium containing oak sawdust, cottonseeds, and sulfur is added to a feed for raising cicada larva at a proper ratio. Thus, the mortality of cicada larva can be remarkably reduced even without an antibiotic treatment, and a growth rate can be improved.COPYRIGHT KIPO 2018본 발명은 면실류, 미강, 비트펄프 및 유황이 함유된 참나무톱밥 배지에서 생산한 느타리버섯 균사체 추출물을 이용한 굼벵이 양식용 사료 및 그 제조방법에 관한 것으로서, 그 구성은 참나무톱밥 65중량%, 면실류 12중량%, 비트펄프 11중량%, 미강 12중량% 및 유황 2 중량%을 혼합한 후 물을 배합, 반죽하여 구비된 배지에 배양된 느타리버섯 균사체를 톱밥 배지에 접종하여 균사체를 배양하여 느타리버섯 자실체를 형성하고,
