Natural Products as Manipulators of Rumen Fermentation
Open accessAbstract
There is increasing interest in exploiting natural products as feed additives to solve problems in animal nutrition and livestock production.Essential oils and saponins are two types of plant secondary compounds that hold promise as natural feed additives for ruminants.This paper describes recent advances in research into these additives.The research has generally concentrated on protein metabolism.Dietary essential oils caused rates of NH 3 production from amino acids in ruminal fluid taken from sheep and cattle receiving the oils to decrease, yet proteinase and peptidase activities were unchanged.Hyper-ammonia-producing (HAP) bacteria were the most sensitive of ruminal bacteria to essential oils in pure culture.Essential oils also slowed colonisation and digestion of some feedstuffs.Ruminobacter amylophilus may be a key organism in mediating these effects.Saponin-containing plants and their extracts appear to be useful as a means of suppressing the bacteriolytic activity of rumen ciliate protozoa and thereby enhancing total microbial protein flow from the rumen.The effects of some saponins seems to be transient, which may stem from the hydrolysis of saponins to their corresponding sapogenin aglycones, which are much less toxic to protozoa.Saponins also have selective antibacterial effects which may prove useful in, for example, controlling starch digestion.These studies illustrate that plant secondary compounds, of which essential oils and saponins comprise a small proportion, have great potential as 'natural' manipulators of rumen fermentation, to the potential benefit of the farmer and the environment.(Asian-Aust.

In the citing paper
“Plant secondary metabolites are natural substances with the potential ability to alter rumen fermentation without causing microbial resistance, and their residual effects can positively affect the animal end products (27, 28).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
