This study was conducted to evaluate natural plant extracts for methane gas reduction in ruminants. Rumen fluid was collected from cannulated Hanwoo cow (450±30 kg) consuming 400 g/kg concentrate and 600 g/kg timothy. The 15 ml of mixture comparing McDougall’s buffer and rumen fluid in the ratio 2 to 1, was dispensed anaerobically into 50 ml serum bottles. Rumen fluid contents were collected and in vitro fermentation prepared control (timothy, 300 mg), ginseng, balloon flower, yucca plant, camellia, tea plant and ogapi extracts were added at the level of 5% against 300 mg of timothy as a substrate (v/w) and incubated for 3, 6, 9, 12, 24, 48, and 72 h. In vitro pH values range 6.55~7.41, this range include rumen titration. The dry matter digestibility was not differ between all treatments and control. Total gas emission was significantly higher (p<0.05) in ginseng and balloon flower treatments on 24 h than in control. Carbon dioxide emission was not differ all treatments on 9 h than in control and significantly higher (p<0.05) yucca plant, camellia and tea plant treatments on 12 h than control. Methane emission was not differ all treatments on 6 h than in control. The rumen microbial growth rate was significantly higher (p<0.05) in ginseng, balloon flower on 12 h and significantly higher (p<0.05) in ginseng, yucca plant, tea plant and ogapi treatments on 24 h than in control.

In this study, the DPPH free radical scavenging activity, antimicrobial effects, growth inhibition and cytotoxicity of herb extracts were determined to screen alternative antibiotics. Hot water extracts of 10 species herbs (Origanum vulgare, Monarda didyma, Echinacea purpurea, Ocimum basilicum, Mentha piperita, Melissa officinalis, Thymus vulgaris, Stevia rebaudiana, Rosmarinus officinalis, Matricaria recutica) were used. DPPH free radical scavenging activity of all herb extracts was ranged from 31.4-49.9%, and significantly great activties were found at Rosmarinus officinalis, Origanum vulgare and Matricaria recutica (P<0.05). Hot water extracts of monarda didyma, origanum vulgare, thymus vulgaris and rosmarinus officinalis showed greater antimicrobial activities compared to others. Additionally, those four extracts represented relatively low cytotoxicity compared to others. As a result, it was found that Origanum vulgare and Rosmarinus officinalis which possessed great antioxidant and antimicrobial activity with less cytotoxicity. So these two herb extracts can be used as an alternative of antibiotics for organic farming.
