“…활성산소종 이 과하게 축적될 경우 세포 손상, 돌연변이, 암 발생, 노화 촉진 등의 부작용이 일어난다 (Dröge, 2002). 식물체에는 활 성산소종을 제거하는 항산화 활성을 가진 물질들이 함유되 어 있기에 (Cho et al, 2015) 식물의 항산화 효과를 이용한 육계의 고온 스트레스 저감 연구들이 수행되어 왔다. 열대 식물인 노니를 첨가한 사료를 고온 환경 내 육계에 급여하 였을 경우 스트레스 지표인 corticosterone의 생성을 억제시 키는 효과가 있다고 보고되었다 (Rajaei-Sharifabadi et al, 2017).…”

This study was performed to investigate the effects of dietary supplementation with ginseng by-products on growth, organ development, blood biochemical profiles, immune response, and stress parameter of broilers reared in high ambient temperatures. One hundred one-day-old male chicks (Ross 308) were used. At week two, the birds were randomly allocated into five dietary groups; control (CON), 0.5% ginseng berry (GB1), 1.0% ginseng berry (GB2), 0.5% ginseng leaves and stems (GLS1), and 1.0% ginseng leaves and stems (GLS2). The temperature was maintained at 32±1℃ from 9 AM to 5 PM. Growth, serum immunoglobulins and corticosterone levels were monitored and analyzed. No significant differences among groups were observed in growth. However, during the finisher period (21～35d) and overall period (7～35 d), body weight gain in all supplemented groups tended higher than CON group. Blood biochemical profiles did not significantly differ among treatment groups except in bilirubin level. Serum immunoglobulins and corticosterone level showed no significant differences among groups. IgM and IgG levels were numerically higher in GLS1 than in other groups, but the difference was not significant. Corticosterone level also tended lower in all supplemented groups than in CON group, and larger decreases were observed in groups with higher ginseng by-product concentration. In conclusion, dietary supplementation of ginseng by-products shows potential to reduce heat stress in growing broilers with no negative effect on productivity.

Ulmus pumila L. bark underwent distilled water extraction under three temperature condition (4℃, room temperature, or 80℃) and two extraction times (1, or 5 min) in order to develop a functional beverage products. Changes in yield, pH, color, total phenolic (TP) content, tannin content and antioxidant activity of the aqueous extracts were evaluated for each extraction temperature and duration. Extraction conditions did not affect yield or pH value of the extracts; however CIE b* values were high in extracts prepared under high extraction temperature (80℃) and long extraction duration (5 min) conditions. Both extraction temperature and duration affected the TP and tannin contents of the extracts; however, all extraction conditions resulted in ≥450 mg GAE/g TP content and ≥80 mg CE/g tannin content. All extracts exhibited ABTS and DPPH radical scavenging ability similar to that of vitamin C. Nitric oxide inhibition activity was lower in the 5 min duration sample than in the 1 min sample. The 4℃ extraction temperature produced an extract with the highest reducing power and hydrogen peroxide values. Extraction temperature also affected sensory evaluation results with the 80℃ extraction temperature producing significantly higher flavor, bitterness, and color score, than those obtained under 4℃ and room temperature extraction conditions.
