광조사의 다양한 파장이 생체에 영향을 미치는데 생체 내 대사 및 화학반응 시 생성되는 가시광선의 극미약광은 세포 간 신호 전달을 증가시켜 면역 기전이 활성될 수 있다. 본 연구는 이유자돈의 사양성적, 산화효소 및 스트레스에 대한 극미약광(LED)의 영향을 알아보기 위해 실시되었다. 이유자돈(Landrace×Yorkshire×Duroc, 21일령 7.04±0.01kg) 120두를 공시하였고, 시험 기간은 이유 후 3단계로 나눠 총 6주간 진행하였다(Phase 1(0-14d), Phase 2(15-28d), Phase 3(29-42d)). 처리구는 Control과 LED로 두 가지로 진행하였으며, 10반복, 반복당 6두씩 배치하였다. 연구 결과, LED 처리에 따라 Phase 3에서 일당증체량 8.96% 증가 및 사료효율 8.93% 개선되었으며, Overall에서 사료효율 6.56% 개선되었다. Malondialdehyde (MDA) 12.58%, glutathione reductase(GR) 7.41%, total antioxidant capacity(TAC) 5.48% 감소로 항산화효소 활성이 개선되었다. 또한 Phase 3에서 LED 처리에 따라 Hair cortisol의 농도가 감소하였다(24.05%, p<0.05). 본 연구결과로 극미약광 조사는 이유자돈의 성장과 항산화활성 및 스트레스를 개선하는데 도움이 되는 것으로 판단된다. Weaning stress is the most common issue in weanling pigs, and increases diarrhea and mortality. Various wavelengths of light irradiation affect the body owing to the association with biophotons. Biophotons are very weak photons in the visible light range generated during metabolic and chemical reactions in vivo. Immune mechanisms are activated by increasing signal transmission between cells through biophoton emission. This study evaluated the influence of ultra-weak light (LED) on growth performance, antioxidant status, and stress of weaned piglets. A total of 120 weaned pigs with an average initial body weight of 7.04±0.01 kg (age: 21 d) were allotted to two treatments (Control and LED) with 10 replicates. Diets prepared in pellet form were administered to the pigs in three phases including Phase 1 (0–14 d), Phase 2 (15–28 d), and Phase 3 (29–42 d). At the end of the study, the average daily gain (8.96%, p<0.05) and feed efficiency (6.56%, p<0.05) of pigs was significantly increased at phase 3 in the LED treatment. Low concentration of malondialdehyde (12.58%, p<0.05) and high concentrations of glutathione reductase (7.41%, p<0.01) and total antioxidant capacity (5.48%, p<0.05) were observed in the LED treatment at Day 42. The concentration of hair cortisol was also decreased (24.05%, p<0.05) in the LED treatment at Day 42. In conclusion, the use of LED for weanling pigs is recommended to improve growth performance by modulating antioxidant capacity and cortisol level in hair.

Black soldier fly (BSF, Hermetia illucens) has been noted as an excellent feed ingredient. However, there is limited information on rearing and processing technology. Thus, this study was conducted to evaluate the substrates for rearing BSF and the optimal processing method for BSF performance. Study separated as 2 experiment, BSF rearing and drying method(Exp 1.) and EP-processing method(exp 2.). During the study, 30 clutches were reared, with 10 per substrate. Three substrates, namely food waste (FW), tofu by-product (TF), and vegetable waste with two drying methods, namely hot air dry (AD) and microwave dry (MW) at expanding (EP) ratios of 5:5 and 7:3, were examined by evaluating their rearing performance, nutrient contents, in vitro digestibility and lipid oxidation stability during storage (0, 14 and 28 days). In experiment 1, the rearing substrates and drying methods were evaluated. Compared with that of conventional methods (FW, AD), the TF substrates and MW method showed higher dry matter contents (3.43%) and in vitro digestibility (1.62%) but lower ether extract contents(3.53%; p<0.05). However, the malondialdehyde (MDA) concentration under MW treatments decreased during storage (5.77%, 4.69% and 3.24%; p<0.05). In experiment 2, compared with that of the 7:3 EP-BSF ratio, the 5:5 EP-BSF ratio showed higher in vitro digestibility (2.70%) and lower MDA concentration during storage (19.19%, 7.96% and 6.42%; p<0.05). In conclusion, the optimal conditions for BSF rearing and ensuring product quality were TF substrates, MW methods and a 5:5 corn:BSF ratio. Therefore, the optimal conditions for producing EP-BSF can present an excellent feed ingredient alternative for swine feed.
