Animal Feeding

Listed are practices for each specific animal that will reduce emissions. Click on the livestock animal link to read the publications.

Remove excess protein from livestock diets to reduce emission, which can also save on feed cost.

Dairy cattle
Dairy
  • Install floors that divert urine away from feces to reduce ammonia emissions
  • Select bedding (e.g. sand or pine shavings) that separates feces and urine
Swine
Swine
  • Use pull-plug housing rather than deep-pit houses
  • Install biofilters on ventilation exhausts
Turkeys
Poultry
  • Change from high-rise layer housing to a manure-belt system
  • Lower in-house temperature
  • Frequently remove manure and change litter
  • Plant vegetative environmental buffers (VEB) outside ventilation fans and install biofiters on exhausts
  • Decrease pH of litter by adding alum
  • Use sodium bisulfate to reduce ammonia emissions from manure
  • Add urea inhibitor to manure and litter in layer houses
  • Add gypsum-zeolite to poultry diets, which can prevent the conversion to NH3 and retain nitrogen in the manure for field application
