Monensin fed cows (MON, 600 mg d–1) were compared with untreated control cows (CON, 0 mg d–1) with respect to the effects of monensin on the production of three greenhouse gases (GHG), ...

  • Adding Value To On-Farm Digesters

    ANAEROBIC digestion of dairy manure and food processing residuals in Michigan is not a new undertaking.

  • Environmental and Economic Perspectives of Milk Production in Feedlot and Grazing Systems

    Abstract Dairy production systems involve large inputs and large outputs. In environmental and economic terms, this means dairying is potentially a large consumer of natural resources and a generator of large amounts of pollutants and waste as green house gases (GHG) and manure. To ensure a sustainable milk production system; it becomes important to understand the environmental and ...

  • Effect of cattle slurry separation on greenhouse gas and Ammonia emissions during storage

    Storage of cattle slurry leads to emissions of methane (CH4), nitrous oxide (N2O), ammonia (NH3), and carbon dioxide (CO2). On dairy farms, winter is the most critical period in terms of slurry storage due to cattle housing and slurry field application prohibition. Slurry treatment by separation results in reduced slurry dry matter content and has considerable potential to reduce gaseous ...
