    • Using Wet Brewers and Wet Distillers Grains on Dairy Farms 

      Chase, L.E. (Dairy Environmental Systems Program, 2021-10)
      Brewers and distillers grains have been used as animal feeds for centuries. Wet brewers (WBG) and wet distillers (WDG) grains may also be available and used as feeds on farms. Using WBG and WDG as animal feed recycles ...
    • Wet Brewers and Wet Distillers Grains in Dairy Cattle Diets 

      Chase, L.E. (Dairy Environmental Systems Program, 2021-10)
      Brewers and distillers grains have been used as animal feeds for centuries. Brewers grain is a co-product of brewing beer. Distillers grains are a co-product of ethanol production. The commercial feed industry routinely ...
    • How Food Waste Contributes to Greenhouse Gases 

      Sharpsteen, Eric; Wright, Peter (Dairy Environmental Systems Program, 2021-08)
      It is estimated that one-third of all food produced in the world each year for human consumption never reaches the table. This leads to increased greenhouse gas (GHG) emissions from the food that is not consumed by the ...
    • Farm Safety - Manure Handling 

      Terry, Timothy; Wright, Peter (Dairy Environmental Systems Program, 2021-06)
      Dairy manure storage is a nutrient efficient and environmentally friendly way to allow recycling of the manure by field application during the growing season. During storage, bacteria and other anaerobic processes breakdown ...
    • Part 5: Biofilter media management considerations 

      Oliver, Jason; Gooch, Curt (2016-09)
      Biofilter performance is directly tied to media management that in turn governs both air flow and microbial activity. At start-up, biofilter media must be managed for the establishment of a robust, targeted contaminant-degrading ...
    • Part 4: Biofilter design information 

      Oliver, Jason; Gooch, Curt (2016-09)
      Design flexibility and the capability to operate across a range of conditions makes biofilters suitable for point-source gaseous emissions from dairies.
    • Part 3: Basics of biofiltration 

      Oliver, Jason; Gooch, Curt (2016-09)
      Biofiltration is a low-cost, robust mitigation technology applicable to various agricultural emissions. Biofilters are essentially a pile of wood chips, mulch, compost or other porous, typically organic, media and its ...
    • Part 2: Applicability of biofilters to dairy point-source emissions 

      Oliver, Jason; Gooch, Curt (2016-09)
      Point-source gaseous emissions from dairies contain complex mixtures of contaminants in ranging concentrations emitted at various flow rates. While most air pollution control technologies have optimal application limits, ...
    • Part 1: Potential point-source gaseous emissions from dairies 

      Oliver, Jason; Gooch, Curt (2016-09)
      Various point sources of gaseous emissions may be associated with modern dairy production. Though most of the generated emissions are benign; the emissions from these point sources may contain odorous, hazardous and ...
    • Part 5: What is known about antibiotic residues in dairy manure? 

      Oliver, Jason; Gooch, Curt (2017)
      Antibiotics are chemicals that kill or impede bacterial cell growth. They are important medicines used by dairy farms to treat bovine bacterial infections, prevent infections, and to a declining degree to promote growth/milk ...
