Effect of plant secondary metabolites on in vitro biohydrogenation of polyunsaturated fatty acids by rumen microbes

The large interest in improving the health value of ruminant products has driven research to find ways to manipulate the rumen fatty acid metabolism. Plant secondary metabolites, such as essential oils, flavonoids, tannins and spaonins have received increasing interest as natural alternatives to the use of antibiotics. Screening of different herb metabolites will be performed using a rumen stimulation in vitro technique.
