    • Antibiotic residuals and anaerobic digestion of dairy manure 

      Ray, Lauren; Gooch, Curt (Dairy Environmental Systems Program, 2020-11)
      Antibiotic residuals found in dairy manure can impact the anaerobic digestion process, and conversely anaerobic digestion can impact residual antibiotics that may be present in dairy manure. While anaerobic digesters are ...
    • Antibiotic residuals and composting of dairy manure 

      Ray, Lauren; Gooch, Curt (Dairy Environmental Systems Program, 2020-11)
      The impact of antibiotic residuals on the composting process and the potential mitigation of antibiotic residuals in stockpiles and compost (turned and in-vessel) from a research review is presented. The specific results ...
    • Antibiotic residuals and solid-liquid separation of dairy manure 

      Wright, Peter; Gooch, Curt (Dairy Environmental Systems Program, 2020-11)
      Antibiotic residuals in dairy manure have different characteristics that facilitate sorting by solid-liquid separation. Partitioning of antibiotic residuals, oxytetracycline and sulfadimethoxine, was measured in an on-farm ...
    • Fate of antibiotic resistance genes in dairy manure treated by anaerobic digestion and composting 

      Ray, Lauren; Gooch, Curt (Dairy Environmental Systems Program, 2020-11)
      The fate of antibiotic resistance genes in anaerobic digestion systems and composting systems is presented from a research review and on-farm study. Generally, higher temperature systems (thermophilic rather than mesophilic) ...
    • Fate of antibiotic-resistant bacteria in dairy manure treated by anaerobic digestion and composting 

      Ray, Lauren; Gooch, Curt (Dairy Environmental Systems Program, 2020-11)
      The fate of antibiotic-resistant bacteria (ARB) in anaerobic digestion systems and also in composting systems is reviewed. The effect of these manure treatment systems on ARB and their associated antibiotic resistance genes ...
    • Feasibility of Reducing a Dairy Farm’s Manure Enterprise Costs Using a Wet Gasification Technology 

      Wright, Peter; Gooch, Curt (Dairy Environmental Systems Program, 2018-10)
      Manure management is a major system on dairy farms and there is a goal to minimize costs and maximize benefits. Adding a wet gasification system to reduce spreading costs and possibly increase byproduct sales was evaluated ...
    • Impact on Antibiotic Resistance by a Solid-Liquid Separator - Rotary Drum Composter Manure Treatment System on a New York State Dairy Farm 

      Ray, Lauren; Gooch, Curt (Dairy Environmental Systems Program, 2020-11)
      An initial assessment of an on-farm manure treatment system consisting of a screw press solid-liquid separator continuously feeding the separated solids to a rotary drum composting unit was conducted to identify possible ...
    • Part 1: Overview of advanced manure treatment 

      Terry, Timothy; Wright, Peter (Dairy Environmental Systems Program, 2020-10)
      Dairy farms are looking for ways to further partition and recover concentrated nutrient components of nitrogen, phosphorus, and potassium, from manure that has been preprocessed, typically with anaerobic digestion and/or ...
    • Part 2: Phosphorus recovery technologies 

      Terry, Timothy; Wright, Peter (Dairy Environmental Systems Program, 2020-10)
      Dairy farms are looking for ways to further partition and recover concentrated nutrient components of nitrogen, phosphorus, and potassium, from manure that has been preprocessed, typically with anaerobic digestion and/or ...
    • Part 3: Nitrogen recovery technologies 

      Terry, Timothy; Wright, Peter (Dairy Environmental Systems Program, 2020-10)
      Dairy farms are looking for ways to further partition and recover concentrated nutrient components of nitrogen, phosphorus, and potassium, from manure that has been preprocessed, typically with anaerobic digestion and/or ...
    • Part 4: Energy extraction 

      Terry, Timothy; Wright, Peter (Dairy Environmental Systems Program, 2020-10)
      Primary methods of manure treatment to produce energy include direct combustion of dried manure and controlled anaerobic digestion to convert manure volatile solids into methane. Additional advanced treatment technologies ...
