Abstract EN
This research was carried out to evaluate the effects of flavone, myricetin, naringin, catechin, rutin, quercetin, and kaempferol at the concentration of 4.5% of the substrate (dry matter basis) on the rumen microbial activity in vitro.
Mixture of guinea grass and concentrate (60 : 40) was used as the substrate.
The results showed that all the flavonoids except naringin and quercetin significantly (P<0.05) decreased the dry matter degradability.
The gas production significantly (P<0.05) decreased by flavone, myricetin, and kaempferol, whereas naringin, rutin, and quercetin significantly (P<0.05) increased the gas production.
The flavonoids suppressed methane production significantly (P<0.05).
The total VFA concentration significantly (P<0.05) decreased in the presence of flavone, myricetin, and kaempferol.
All flavonoids except naringin and quercetin significantly (P<0.05) reduced the carboxymethyl cellulase, filter paperase, xylanase, and β-glucosidase activities, purine content, and the efficiency of microbial protein synthesis.
Flavone, myricetin, catechin, rutin, and kaempferol significantly (P<0.05) reduced the population of rumen microbes.
Total populations of protozoa and methanogens were significantly (P<0.05) suppressed by naringin and quercetin.
The results of this research demonstrated that naringin and quercetin at the concentration of 4.5% of the substrate (dry matter basis) were potential metabolites to suppress methane production without any negative effects on rumen microbial fermentation.
