Abstract

The objective of this study is to investigate the effects of Cynanchum wilfordii (CW) on cell viability, anti-oxidant activity, volatile fatty acid (VFA) production and methane gas production. Collected rumen fluid incubated with CW powder (1% w/v) for 12 and 24 hours were analyzed for pH, VFAs and methane. Alamar blue assay showed no significant difference on the viability of 3T3-L1 and C2C12 cells treated with CW for 24 hours. TBARS data showed a dose dependent increase on the antioxidant activity of CW. VFAs increased in the CW-treated groups compared to the control group. In addition, propionate increased more than other VFAs by the treatment with CW. There was a significant decrease in methane gas production in batch culture treated with CW in 12hrs. In conclusion, it was suggested that Cynanchum wilfordii could manipulate rumen fermentation considered by increasing VFA production and inhibition of methanogenesis.
