Red ginseng marc (RGM) has been used on primary industries using fertilizer or forage, and it mostly has been dumped. To improve utilization of RGM, the biological activities of RGM were examined. RGM was extracted and fractionated using various solvents and their biological activities were compared. The hexane fraction from the methanol extract of RGM (RGMMH) showed strong anti-cancer activity (58.56 ± 6.04% at 100 ㎍/mL) and anti-inflammatory effect (65.72 ± 1.33% at 100 ㎍/mL). But, oil extract of RGM extracted with hexane (RGMH) showed low activities (anti-cancer: 16.42 ± 3.33%, at 100 ㎍/mL, anti-inflammatory activity: 29.46 ± 2.10%, at 100 ㎍/mL). Their metabolites were analyzed using HPLC. Panaxydol known as anti-cancer compound of RGM was one of major compounds in RGMMH. Meanwhile, panaxydol was detected in trace amount in red ginseng marc oil (RGMH). In addition, RGMMH and RGMH showed big differences in HPLC profiling. This research suggests optimal extraction method of RGM oil.

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.

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 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.

The aim of the present study was to determine the effects of soil microbial agent with red ginseng marc on growth of watermelon during 5 months. The three treatments were distributed in a completely randomized design with four replicates per plot. After 1 week in planting dates, the growth of watermelon (full length, stem thichness, leaf length and lead width) showed no significant difference in all treatments. During elongation stage (20 days), soil microbial agent with red ginseng marc was increased by 5% in leaf thickness (May 23) and 7~14% in leaf length (May 16 and 23) when compared to other treatments. For changes in fruit bearing thickness, there were no differences among treatments. Characteristics of watermelon in harvest season have an effect on harvest and length, stalk length, naval length, weight, sugar content and yield, except for harvest and width. In particular, yields increased with treatments with two soil microbial agent (7~12%), indicating that soil microbial agent with red ginseng marc showed higher yield than the other treatments. In conclusion, red ginseng marc-treated soil microbial agents have a positive effect on the harvest season of watermelon and can provide useful information for the selection of the functional microbial properties and the registration of microbial fertilizer.

This study was conducted to evaluate the effects of red ginseng marc powder on egg freshness in laying hens during 4 weeks. A total of 60 Hy-line Brown laying hens, 50 week of age, were randomly assigned to 2 groups with diets containing 0% and 2% red ginseng marc powder. There were 3 replications per group with 10 laying hens per pen. Throughout the period of the trial, there were no effects of red ginseng marc powder on egg weight (but not 4 weeks). Haugh Unit (HU) values were observed by showing significant differences between red ginseng marc powder and controls at 0 and 4 weeks, except for HU at 1 through 3 weeks. For egg yolk color, red ginseng marc powder has no difference in comparison with controls at 0, 3 and 4 weeks (but not 1 and 2 weeks). In conclusion, the dietary supplementation with 2% red ginseng marc powder improved HU values throughout the experiment.

This study was conducted to determine the effects of mixed Korean red ginseng marc with aluminum sulfate on gas concentration and volatile fatty acid (VFA) in poultry litter during 4 weeks in terms of livestock and environment managements. A total of 240 broiler chicks were randomly allocated to four treatments in four replications and 15 birds per replicate. The four treatments was mixed to rice hull under each pen at 0, 10 g or 20 g red ginseng marc + 90g aluminum sulfate, and 100g aluminum sulfate per kg poultry litter (rice hulls). Carbon dioxide, methane, acetic acid, and propionic acids were measured weekly. The results that could be available include: First, during the experimental period, carbon dioxide emissions were not remarkably different among treatments. Second, no differences were observed among treatments in methane emissions at 2 weeks through 4 weeks, but at 1 week, the reduction in methane emissions was in following order: 100 g aluminum sulfate > 20 g red ginseng marc + 90 g aluminum sulfate > 10 g red ginseng marc + 90 g aluminum sulfate > control. Third, in spite of statistically differences, treatment with 10 g or 20 g red ginseng marc + 90g aluminum sulfate, and 100g aluminum sulfate reduced acetic acid and propionic acid as a function of time, except acetic acid in aluminum sulfate treatment at 2 and 4 weeks. In conclusion, the results indicated that like aluminum sulfate, using 10 g or 20 g red ginseng marc with aluminum sulfate was effective in decreasing methane and propionic acid released from poultry litter.
