Goal of our research was to determine effects of hop cones on in vitro activity of rumen microorganisms, effect on degradability and digestibility of nutrient and how hop cones affect the microbial biomass production. In addition, we wanted to determine if hop cones have effects also on rumen fermentation products and their effects on ratios between short chain fatty acids, from which the release of methane and carbon dioxide were calculated. The results showed that hop variety did not have any effects on rumen microbe activities (gas production and concentrations of acetic, propionic and butyric acids). Hop variety did not have any effect on dry matter and crude protein degradability and digestibility and did not affect microbial biomass production. On contrary, the concentration of hop cones affected all above mentioned parameters except on the digestibility of dry matter and crude protein. These changes in microbial activity and dry matter and crude protein degradability suggested that microbial biomass production increased when the hop cones were added to the ruminant diet.
