Livestock manure produces several gases including four main toxic gases, hydrogen sulfide, methane, ammonia and carbon dioxide. [4] In animal housing it is very common in swine and beef breeding to have manure storage under the building's floor. In this setup low concentrations of these toxic gases are commonly noted throughout the year. [4]

The spokesman said the cost to produce renewable natural gas from cattle manure is the same as traditional production. South Dakota Public Utilities Commissioner Chris Nelson attended the event.
The production of slurry is especially common in housed dairy cattle. Treatment. Whilst solid manure heaps outdoors can give rise to polluting wastewaters from runoff, this type of waste is usually relatively easy to treat by containment and/or covering of the heap.
For instance, sheep manure is high in nitrogen and potash, while pig manure is relatively low in both. Horses mainly eat grass and a few weeds, so horse manure can contain grass and weed seeds, as horses do not digest seeds as cattle do. Cattle manure is a good source of nitrogen as well as organic carbon. [3]
A cattle feedlot too small to need a state-required manure management plan has apparently polluted Iowa streams for years, the Iowa DNR says
Compost bedded pack barns are typically bedded with wood shavings/sawdust, or other organic materials that are compostable. [ 3 ] For the composting process to work in a CBP, the internal temperature of the pack must be maintained at approximately 43.3–65.0 °C (109.9–149.0 °F) and have a moisture content at approximately 40–60%.
