The removal of lipids from grass powder significantly increased NDF digestibility of grass by mixed rumen microorganisms. When the lipids from the grass were adsorbed to the grass residue (grass powder from which lipids were removed), NDF digestion decreased to a value less than that of the original grass powder. These results indicate that grass lipids have an inhibitory effect on the growth or activity of fibrolytic bacteria. The growth of protozoa and bacteria was also suppressed by grass
