  • Research highlights cattle emissions reduction opportunity

    Researchers in Denmark have measured the quantities of greenhouse gases in the breath of dairy cows and demonstrated a heritable variability between individual animals. “This means that we have an opportunity to select for breeding those individuals which will produce offspring that generate less methane,” says Dr Jan Lassen who led the research project on individual methane ...

  • Transport Of Fecal Bacteria From Poultry Litter and Cattle Manures Applied to Pastureland

    Abstract  Land applications of manure from confined animal systems and direct deposit by grazing animals are both major sources of bacteria in streams. An understanding of the overland transport mechanisms from land applied waste is needed to improve design of best management practices (BMPs) and modeling of nonpoint source (NPS) pollution. Plots were established on pasturelands receiving ...

  • Tapping the potential of codigestion

    Codigestion refers to processing multiple biodegradable substrates (feedstocks) in an anaerobic digestion (AD) system. A more contemporary definition refers to the digestion of a combination of select biodegradable feedstocks with a base substrate that an AD system was designed to handle. The intent is to maximize the production of biogas (i.e., renewable energy) by adding substrates that produce ...
