This study was conducted to examine the effects of defaunation (removal of live protozoa) on fermentation characteristics, degradation of ryegrass hay and $CH_4$ (methane) production by rumen microbes when incubated with plant oils (SO, sunflower oil and LO, linseed oil) in vitro. Sodium lauryl sulfate (0.000375 g/ml) as a defaunation reagent was added into the culture solution and incubated anaerobically up to 24 h at $39^{ circ}C$ . pH from defaunation was increased for all treatments from 6 h incubation times (p $C_2$ (acetate, p $C_3$ (propionate), however, was increased by defaunation at all incubation times (p $C_2$ to $C_3$ was decreased by defaunation at all incubation times (p $CH_4$ production, $CH_4$ % in total gas and $CH_4/CO_2$ at all incubation times (p $CH_4$ production (p $CH_4$ % in total gas (p $CH_4$ production. No difference, however, was observed in all the examinations between SO and LO. |
