The purpose of this study was to evaluate effects of replacing soybean meal with perilla seed meal (PSM) on growth performance, proximate composition of meat, meat quality, and fatty acids composition of meat in broilers. A total of 60 one-day-old chicks of ROSS 308 (initial body weight of 44.8 ± 0.4 g) were randomly allotted to four treatment groups (15 replicate cages with 1 broilers per cage) in a period of 5 weeks. Dietary treatments included control (CON) basal diet (corn-soybean meal-based diets) and test diets in which PSM was included at 0.5% (T1), 1% (T2), or 2% (T3) to gradually replace soybean meal. At the end of experiment, all broilers were slaughtered for collecting breast and thigh meat. At 5 weeks, T2 and T3 treatment groups had higher (p < 0.05) body weights than CON and T1 treatment groups. Weight gain was increased (p < 0.05) in T2 and T3 treatment groups. Feed intake was decreased (p < 0.05) in T3 treatment group. Broilers in T2 treatment group had lower (p < 0.05) feed conversion ratio than those in other treatment groups. In proximate composition of breast meat, there was no significant (p > 0.05) difference in moisture and ash. Fat composition of breast meat was significantly (p < 0.05) increased in T2 and T3 treatment groups. Regarding meat quality, broilers fed T3 diet had higher (p < 0.05) water holding capacity than those fed other diets. Regarding fatty acids composition of thigh meat, broilers fed T3 diet had higher (p < 0.05) linolenic acid than those fed other diets. In conclusion, soybean meal replaced by 2% perilla seed meal in broiler diet can improve growth performance, meat quality, and fatty acids composition of thigh meat in broilers. Perilla seed meal can be a lot of potential alternatives feedstuff for soybean meal in this study.

본 연구는 국내에서 사용되고 있는 몇 가지 단백질 원료사료를 사용하여 단백질 fraction과 in situ 단백질 분해율을 구한 다음 이들 사이에서의 상관관계를 살펴보고자 실시하였다. 원료사료는 대두박, 콘글루텐, 면실박, 카폭박 및 임자박이었다. 단백질 fraction은 CNCPS에서 제시하는 방법으로 구하였으며, in situ 단백질 분해율은 캐뉼라가 장착된 홀스타인 거세우 3두를 이용하여 반추위에서 원료사료를 4, 8, 12 및 24시간 배양하여 구하였다. 단백질 fraction 중 A fraction은 카폭박이 14.6%로 가장 높았고, 콘글루텐이 0.6%로 가장 낮았다(P<0.05). B1 fraction은 대두박이 8.27%로 가장 높았으며, B2 fraction은 대두박과 면실박이 74%로 가장 높았다. B3 fraction은 임자박이 40%로 다른 원료사료에 비교해 뚜렷하게 높았다. C fraction은 콘글루텐이 약 42.5%로 가장 높았다. In situ 조단백질 분해율은 대두박이 98%로 가장 높았고, 콘글루텐은 28%로 가장 낮았다. 단백질 fraction과 in situ 분해율 사이의 상관관계를 보면, 쉽게 용해되는 부분(A, B1 fraction vs a값) 사이에, in situ 조단백질 분해율과 소화가능한 단백질 fraction 사이에, 그리고 in situ 조단백질 분해율에서 a값을 제외한 값과 B2+B3 fraction 사이에는 상관관계가 높았다(P<0.01). 본 연구결과에 의하면, 단백질 fraction은 원료사료의 반추위내 분해율을 추정하는 데 이용될 수 있을 것으로 사료되며, 앞으로 더 정확한 평가를 위해서는 더 많은 원료사료에 대한 분석이 필요하다고 본다.

BACKGROUND: Biochar (BC) has a great potential for enhancing soil fertility and carbon sequestration while facilitating beneficial waste disposition. Therefore, it is essential to assess and mitigate any inadvertent consequences associated with soil biochar amendment. Earthworm activity is very vital in the soil system, yet there are a limited number of studies that have examined their impact resulting from biochar application to soil. METHODS AND RESULTS: In this study, the survival, growth, reproductive tests, and oxidative DNA damage tests (measured by 8-hydroxydeoxyguanosine (8-OHdG) and catalase (CAT) activities) to assess the potential toxicity to earthworm Eisenia fetida in artificial soil amended with BCs were investigated. The BCs derived from perilla meal, sesame meal, and pumpkin seed were pyrolyzed at 300 and $550^{\circ}C$, and then amended with soil at a rate of 5%. All the earthworms survived, but lost weight compared to control soil after 28 day incubation period. Moreover, the BC-amended soils did not significantly affect the cocoon numbers of earthworms. Slightly higher concentrations of 8-OHdG and CAT were observed in earthworms present in BC-treated soil than those in control soil. Furthermore, the 8-OHdG concentrations in the soil amended with BC produced at $550^{\circ}C$ were greater than those at $300^{\circ}C$, and it slightly decreased as the incubation time increased. CONCLUSION: These observations could be due to higher contents of toxic metal(loid)s and also higher pH in BCs pyrolyzed at $550^{\circ}C$ than $300^{\circ}C$. While BC is efficiently being used in agricultural fields, this study suggests that it is required to assess the unintended negative impacts of BC on soil ecosystems.

Korean vegetable dishes-Na mul are indigenous and popular foods for a long time, and have been eaten by not only the common people but also the royale people in the ordinary meal and customary affairs. Grains are principal item of diet for Koreans and additions of Na mul in diet provide the nutritional minerals and vitamins. Especially vegetable oils in seasoning played the important role in nutrition balance. This manuscript historically investigate the Korean vegetable dishes-especially Na mul, Seng chae, Ssam, and the vegetables, additional ingredients and seasonings. 1. Foreign vegetable were introduced very actively. As the result of it, the more variety of vegetables are available. 2. Vegetable oils such as sesame oil, perilla oil, roasted sesame seed and pine nuts, etc were widely used for seasonings. 3. Seng chae dishes had been prepared with more than two different kinds of vegetables. Seasonings are used from the various sources, and combination of ingredients and development of condiments are expected to research further. 4. Ssam foods basically used uncooked vegetables, but steaming and boiling are also common methods.

Optimization of the dietary formulation is the most effective way to reduce methane. Nineteen feed ingredients (brans, vegetable proteins, and grains) were evaluated for their potential to generate methane and change methanogen diversity using an in vitro ruminal fermentation technique. Feed formulations categorized into high, medium and low production based on methane production of each ingredient were then subjected to in vitro fermentation to determine the real methane production and their effects on digestibility. Methanogen diversity among low, medium and high-methane producing groups was analyzed by PCR-DGGE. The highest methane production was observed in Korean wheat bran, soybean and perilla meals, and wheat and maize of brans, vegetable protein and cereal groups, respectively. On the other hand, corn bran, cotton seed meal and barley led to the lowest production in the same groups. Nine bacteria and 18 methanogen 16s rDNA PCR-DGGE dominant bands were identified with 83% to 99% and 92% to 100% similarity, respectively. Overall, the results of this study showed that methane emissions from ruminants can be mitigated through proper selection of feed ingredients to be used in the formulation of diets.
