This study was conducted to investigate the effects of dietary supplementation of various types of fermented red ginseng marc with red koji to laying hens on eggshell and egg yolk quality characteristics. A total of 240 Hy-line Brown laying hens (40 wk of age) were randomly allotted to 24 pens (6 replicates per treatment and 10 laying hens per replicate). Experimental diets consisted of 4 treatments containing basal diet (control), 1% fermented red ginseng marc powder with red koji, 1% fermented red ginseng marc pelleted with red koji and 1% fermented red ginseng marc coated with red koji. During the 8-wk feeding trial, there were no significant differences in eggshell strength, eggshell thickness and eggshell color among the treatments, except for eggshell strength at 4 and 8 wk and eggshell thickness at 0 wk. In addition, no differences in egg yolk color and egg yolk index were found for all treatments throughout the 8-wk feeding period, except for egg yolk color at 0 wk. Thus, using various types of fermented red ginseng marc with red koji to laying hens did not improve eggshell and egg yolk quality characteristics.

We conducted two experiments to evaluate effects of feeding various types of red ginseng marc and Houttuynia cordata (H.cordata) on blood profiles of poultry in a completely randomized design. In experiment 1 (28 d), a total of 240 broilers (Arbor acres) were used. Four dietary treatments (15 broilers per pen with four replicate pens per treatment) were included: (1) control, (2) 2% red ginseng marc, (3) 1% fermented red ginseng marc with red koji, and (4) 2% liquid red ginseng. There were no significant differences in HDL and LDL-cholestrol among treatments (P > 0.05), but total cholesterol and triglyceride decreased in diets supplemented with red ginseng marc and 1% fermented red ginseng marc with red koji compared to that in the control treatment (P < 0.05). In experiment 2 (38 d), a total of 240 Pekin ducks were randomly divided into 4 groups by dietary treatments (control, 1% fermented H. cordata powder with red koji, 1% fermented H. cordata pelleted with red koji, and 1% fermented H. cordata coated with red koji) with 4 replicates of 15 ducks in each group. Total cholesterol and VLDL-cholesterol were not affected by diet with various types of H. cordata. However, increase in HDL-cholesterol and decrease in LDL and VLDL-cholesterol were greater in treatments with different types of H. cordata than in the control treatments (P < 0.05). In conclusion, using various types of red ginseng marc and H. cordata in poultry diets was effective for increasing HDL-cholesterol and decreasing total, LDL, and VLDL-cholestrol or triglyceride.

This study investigated the physicochemical properties of Pekin duck breast meat obtained from ducks fed diets consisting different types of sipjeondaebo-tang by-products and red ginseng marc with fermented red koji during storage. A total of 180 Pekin ducks (0-day old) were divided into four groups, each consisting of three replicates (15 ducks per pen). This study investigated diets with four types of treatments: control (basal diet),1% blend powder, pelleted 1% blend, and coated pellets of 1% blend; the blend was a mixture of sipjeondaebo-tang by-products powder and red ginseng marc with fermented red koji. There was no significant difference (p>0.05) in duck breast meat pH on storage days 3 and 7, TBARS on storage days 0 through 7, and DPPH radical scavenging on storage days 0 and 7. However, the pH values on storage day 0 and DPPH radical scavenging on storage day 3 were significantly different (p<0.05) in the meats from control and treated diet fed ducks. Especially, on storage day 7, the breast meat from ducks treated with different types of sipjeondaebo-tang by-products and red ginseng marc with fermented red koji showed lower TBARS values and increased DPPH radical scavenging activity compared to the control. In conclusion, addition of different types of sipjeondaebo-tang by-product and red ginseng marc with fermented red koji to 1% blend might be helpful in increasing antioxidant effects and reducing product wastage.

홍삼박을 에탄올 발효의 원료로 활용하기 위하여 홍삼박을 탄수화물 분해효소와 단백질분해효소로 처리한 결과 환원당의 함량이 7.2 g/L에서 101.1 g/L로 증가하였다. 홍삼박 효소분해물에 영양성분을 추가하지 않고 시판 효모를 접종하여 $25^{\circ}C$에서 7일간 발효한 결과 에탄올은 29.3 g/L까지 생성되었으며 총당대비수율은 0.274 g/g로 계산되었다. 이는 대조군보다 에탄올 생산량은 1,000% 이상, 수율은 50% 이상 향상된 결과이다.

홍삼 추출액 제조 후 생산되는 부산물인 홍삼박의 식품 소재화를 위해서 열풍 건조시킨 후 초미세 분말화 하였으며, 쑥 분말 첨가에 따른 고초균 발효 특성을 조사하였다. 홍삼박 분말에 탈지대두분말 3%와 monosodium glutamate(MSG) 2%, 쑥을 농도별(0~3%)로 첨가하여 발효하여 분석하였다. 홍삼박 발효물의 tyrosine 함량은 쑥 3% 첨가 시 581.3 mg% 로 가장 높은 함량을 나타낸 반면 protease 활성은 쑥을 첨가할수록 감소하는 경향을 나타냈으며 쑥을 첨가하지 않은 구에서 277.5 unit/g으로 가장 높은 활성을 나타냈다. 점조도 측정 결과 쑥 3% 첨가 시 $8.8\;Pa{\cdot}s^n$으로 가장 높게 나타났고, 점질물 함량은 쑥을 첨가하지 않은 구에서 11.5%로 가장 높은 함량을 나타냈다. 고분자 점질물인 PGA함량을 GPC를 이용하여 측정한 결과 쑥을 첨가하지 않은 구에서 15.9 g/kg 이었으며 분자량은 1,100 kDa으로 나타났다. 첨가된 MSG 전환율을 약 80% 정도로 나타냈으며, 쑥 첨가에 따른 전환율에 효과는 볼 수 없었다. DPPH radical 소거활성은 쑥 3% 첨가된 발효물에서 물과 70% 주정 추출물 각각 $IC_{50}$값이 0.62 mg/mL, 0.57 mg/mL로 나타났다. ABTS radical 소거 활성은 쑥 3% 첨가 시 물 과 70% 주정 추출물에서 각각 $IC_{50}$값은 1.24 mg/mL, 1.34 mg/mL로 나타났다.

Red ginseng marc is a by-product of Korean red ginseng (panax ginseng CA Meyer) and contains ginsenoside which has pharmacological effects. The Korean red ginseng marc was fermented with Bacillus subtilis (RGMB). This study was carried out to investigate the RGMB effect on swine immunity. The variation of ginsenoside depending on the RGMB fermentation time was analyzed. Swine (Landrace${\times}$Yorkshire) were divided into control group (basic diet) and RGMB group (RGMB 1% diet). One percent RGMB was fed to the RGMB group for 28 days. The biochemical parameters, cytokine and immunoglobulin were analyzed. For 48 hours of fermentation on RGMB, ginsenoside Rb1 had increased 180.94%, Rg3 235.85%. Rg1 wasn't detected before fermentation, but was detected after 48 hours of fermentation. The RGMB had effect of deceasing initial AST concentration $79.33{\pm}12.85U/L$ to $54.00{\pm}14.46U/L$ in final and was significantly lower (P<0.05) than control in final. In final RGMB had significantly lower (P<0.05) ALT concentration of $48.57{\pm}8.26U/L$ comparing with control group of $65.43{\pm}10.31U/L$. RGMB had the effect of significantly decreasing (P<0.05) $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ concentration of $2.44{\pm}1.31ng/mL$, $0.71{\pm}0.36ng/mL$ and $0.51{\pm}0.21ng/mL$. The IgA concentration had significantly increased (P<0.05) in RGMB group of $0.56{\pm}0.06mg/mL$ in final. These results demonstrate that RGMB has effect of increasing immunity and practicable to use as feed additives on swine.
